Basic principles of climate control components Guide to selecting suitable units. 1.1 As electronic components become ever smaller and are more densely packed in enclosures and electronic cases, systems are becoming increasingly sensitive to external factors such as dust, oil, moisture and temperature. Heat in particular is a deadly enemy of sensitive microelectronics.
Fast selection Before you start, please consider your peripheral conditions such as external temperature, internal temperature and protection category. 2.1 Heat dissipation For targeted, effective cooling, it is important to ensure correct calculation of the required climate control components and where applicable, perform thermal analysis using computer-assisted flow models (CFD – Computational Fluid Dynamics). Basic selection: TItarget > TUmax.
Project planning General information Calculation bases for enclosure climate control 3.1 In natural convection, heat loss is dissipated to the outside via the enclosure panels. The pre-requisite for this is that the ambient temperature must be lower than the temperature inside the enclosure. The maximum temperature increase (ΔT)max. which may occur inside an enclosure compared with the ambient air is calculated as follows: . Qv (ΔT)max. = k A . Qv = Heat loss installed in the enclosure [W] .

Cooling units Applications Ambient conditions Cooling units keep the enclosure internal temperature at a constant level, even to below room temperature. The air routing meets individual requirements. Two separate circuits prevent the ingress of dust into the enclosure. Heat Dust ● Climate controlled enclosures ● Roof-mounted cooling units ● Wall-mounted cooling units 4.
Cooling units Selection criteria Enclosure climate control poses escalating demands on integration and adaptation to the local conditions and the existing process control and monitoring system. Rittal offers the right solution to suit every requirement.
Cooling units Assembly Sealing of the enclosure The enclosure must be sealed on all sides (IP 54). Particular attention should be paid to the sealing of the area around the cable entry openings and above all, the floor section of the enclosure. Additionally, the door seal must be in perfect condition. The sealing material included with the cooling units must be applied in accordance with the installation instructions. Take care not to bend the side panel or enclosure door. 4.
Cooling units Air routing External circuit Flow and siting conditions In the outer circuit, enclosure cooling units should be spaced 200 – 400 mm from the wall and/or from each other (air inlet and outlet openings). In order to ensure adequate air circulation, at least one air outlet opening must be kept free. If this clearance cannot be maintained, air baffle plates will need to be used. The external circuit supports all siting variants.
Cooling units Air routing Free air circulation 200 It is important to ensure “even” air circulation inside the enclosure. Air inlet and outlet openings in the internal circuit must on no account be obstructed by electrical installations. This would prevent air from circulating inside the enclosure. Under such conditions, the cooling capacity of the device would not be adequately utilised. A clearance of > 200 mm must be guaranteed.
Cooling units Air routing Air-ducting system for TopTherm roof-mounted cooling units With the air duct system, it is possible to route the cold air directly to specific areas of the enclosure. This effectively eliminates the risk of “short circuits” in the air circulation due to self-ventilated components. Note: ● Never direct the cold air flow straight at active components. ● Route the air duct system directly downwards with no bends. ● Cold air must be able to escape unobstructed at the end of the duct.
Cooling units Condensate management Condensate routing (roof-mounted units) 1 2 Any condensation which forms on the evaporator coil (with high humidity and low enclosure interior temperatures) is routed to the right and/or downwards out of the device via a drain in the evaporator tray. For this purpose, a piece of hose should be connected to one of the two condensate nozzles (1 or 2). The drain which is not required should be tightly sealed. The condensate must be able to run off freely.
Cooling units Condensate management Condensate evaporation, electrical integrated into TopTherm cooling units Condensate arising inside the enclosure or on the evaporator coil of the cooling unit is effectively evaporated. The evaporator device inside the cooling units has a very high evaporation output (several litres per day). This is achieved thanks to the principle of direct evaporation. Important note: The enclosure must be sealed on all sides.
Cooling units Electrical connection and control Supply connection ● Supply connection data (voltage and frequency) must be observed in accordance with the rating plate. ● The pre-fuse specified on the rating plate must be used.

Cooling units Benefits Rittal TopTherm cooling units offer holistic process protection. Above all, this includes the cooling of sensitive electronics in enclosures and cases for industrial process control. Climate control is largely independent from the respective ambient conditions. But these are not isolated solutions – with Rittal, everything is interconnected. The monitoring and control of these eco-friendly, energy-efficient units is perfectly interconnected. 4.

Recooling systems Applications Ambient conditions Recooling systems ensure centralised, efficient cooling and provision of the cooling medium (generally water), and are used with particularly high heat loads. They may serve several pieces of equipment simultaneously, and are particularly effective in terms of cool- Heat Dust ing output. 5.
Recooling systems Selection criteria Generally speaking, recooling systems are divided into open and closed systems. In the pressure-sealed configuration, the water circuit is equipped with a pressure relief valve and automatic exhaust. In this way, the cooling medium volume can be routed directly to the consumer with the integral pump, and no additional tank reservoir is needed. Recooling systems designed as an open system have a tank made of PP plastic or stainless steel 1.

Recooling systems Selection criteria Recooling systems (for oil) see Catalogue 31, page 613/614 When cooling oil, particular requirements are placed on a recooling system. The recooling systems for oil, equipped with a high-capacity geared pump, are designed as standard as once-through coolers without a tank, and ensure efficient cooling of the hydraulic oil that is heated during the course of the machining process.
Recooling systems Assembly Unity with enclosures For example, recooling systems may be connected directly to a bayed enclosure suite, providing effective, centralised cooling for all enclosures and housings on a machine or system. 2 2 Recooling systems in the TS 8 Top enclosure system are easily integrated into existing enclosure combinations. For applications in confined conditions, the Mini-recooling systems for wall and roof mounting are ideal, with their space-saving, compact design.
Recooling systems Notes/benefits Assembly and commissioning In the case of air-cooled recooling systems, the following minimum distances from the wall and ceiling should be observed: 2 1 Recooling system 1 Wall: At least 1x condenser height 2 Ceiling: At least 3x the condenser height Distance from equipment Site the recooling system close to the equipment in order to avoid long distances, which could lead to performance losses.
Air/water heat exchangers Applications Ambient conditions Air/water heat exchangers effectively dissipate high heat losses. Thanks to the spatial separation of the heat exchanger and recooling system, the room is not burdened with waste heat. Heat Dust Ideal at any installation site 6.1 High ambient temperatures and extreme levels of contamination are ideal conditions for the use of air/water heat exchangers.
Air/water heat exchangers Selection criteria Application example: Parallel connection of 4 air/water heat exchangers Example: Parallel connection of air/water heat exchangers with cold water supply via a recooling system. Overflow valves and bypass control should be integrated into the recooling system and the customer's own pipeline system respectively. 1 Recooling system 2 2 2 2 2 Air/water heat exchangers 3 Corner safety valve 4 1 4 4 SK 3301.900/.910/.
Air/water heat exchangers Assembly Application benefits Compact and lightweight Air/water heat exchangers have a low weight and a comparatively low volume in relation to the heat loss dissipated. As a result, they are easily mounted on vertical enclosure surfaces or on the roof. Air/water heat exchanger integrated into the side panel The side panel combines effective heat dissipation with minimum space requirements. It may be used in all 600 mm deep, 1800 mm/2000 mm high TS 8 enclosures.
Air/water heat exchangers Air routing Free air circulation 200 It is important to ensure “even” air circulation inside the enclosure. Air inlet and outlet openings in the internal circuit must on no account be obstructed by electrical installations. This would prevent air from circulating inside the enclosure. Under such conditions, the cooling capacity of the device would not be adequately utilised. A clearance of > 200 mm must be guaranteed.

Air/water heat exchangers Condensate management Note: Condensate discharge (wall-mounted units) For wall-mounted units, a hose should be connected to the condensate nozzle on the bottom of the unit. The condensate drain pipe should be laid with a gradient, taking care to ensure there are no kinks in the pipe! Condensate discharge 6.5 If the condensate discharge is extended, its cross-section must not be reduced. Condensate hose SK 3301.612 (12 x 2) For unit(s) SK 3209.xxx/SK 3210.xxx SK 3364.

Air/water heat exchangers Electrical connection and control Intelligent control The two controller variants for operational reliability offer a comprehensive range of functions. Essential control electronics are well protected and cooled in the inner circuit.
Air/water heat exchanger Benefits The air of the enclosure interior may also be cooled to below the level of the external temperature, if required, by using cooling water from a central recooling system. The ingress of dust from outside into the cooled enclosure is prevented. The waste heat from the enclosure does not raise the temperature of the ambient air, provided the heat exchanger and cold water supply system are spatially separated from one another.
Air/air heat exchanger Applications Ambient conditions Air/air heat exchangers use the external temperature for cooling. By separating the internal and external air circuits, the ingress of dust into the enclosure is prevented. Cool Dust Outstanding performance and design The requirement for use of air/air heat exchangers is that the ambient temperature must be below the required enclosure internal temperature.
Air/air heat exchangers Selection criteria Cool ambient air Air/air heat exchangers utilise the ambient air to cool the air in the enclosure interior. Based on the counterflow principle, the completely separate airflows are routed through the heat exchanger module by powerful fans. ● Ambient conditions: The ambient temperature Tu must be lower than the permissible enclosure interior temperature. A temperature difference of 10 K is ideal. ● Also ideal for use in dusty ambient conditions. 7.
Air/air heat exchangers Assembly Sealing of the enclosure The enclosure must be sealed on all sides (IP 54). Particular attention should be paid to the sealing of the area around the cable entry openings and above all, the floor section of the enclosure. Additionally, the door seal must be in perfect condition. The sealing material included with the heat exchangers must be applied in accordance with the installation instructions.

Air/air heat exchanger Benefits The requirement for using air/air heat exchangers is that the ambient temperature must be below the required enclosure internal temperature. Dust and aggressive ambient air are unable to enter the enclosure interior, thanks to the two separate air circuits. ! Benefits in brief ● Specific thermal out- put from 17.
Fan-and-filter units Potential applications/selection critiera Ambient conditions Fan-and-filter units utilise the ambient air for direct cooling of the enclosure interior. This requires cool, reasonably clean ambient air. Cool Application diversity and design In most cases, it makes sense to install the axial fan with the air directed from outside into the enclosure so that overpressure is created inside the enclosure, as per the delivered state. This helps to avoid the ingress of unfiltered ambient air.
Fan-and-filter units Potential applications/selection critiera Practical example of a fan-and-filter unit Fan-and-filter units are used in virtually all segments of industry: from the smallest enclosures, to command panels and consoles, through to large and bayed enclosure systems. They are the easiest method of protecting against overheating and hotspots. 5 5 The basic pre-requisite for their use is that the ambient temperature must be significantly below the enclosure internal temperature.
Fan-and-filter units Assembly Benefits of Rittal fan-and-filter units and outlet filters ● All-round foamed-in seal as standard to achieve a protec- tion category of IP 54 ● Additional mounting catches for fast, screwless assembly, to ensure secure attachment to the enclosure ● A new unlatching system for removal of the louvred grille Super-simple assembly without screws Benefits: ● Air throughput from 20 to 700 m3/h ● Super-fast assembly ● Air flow direction may be reversed from extracting (standard set
Fan-and-filter units Benefits Fan-and-filter units are ideal for dissipating heat loads costeffectively. The pre-requisite is that the ambient air must be relatively clean and with a temperature below the desired enclosure internal temperature. The entire range of fan-and-filter units is now also available with EMC shielding and all required rated voltages. ! Benefits in brief ● Air throughput from 20 m3/h to 700 m3/h ● Super-fast assembly ● IP 54 as standard ● Reversing the direc- tion of air flow.
Enclosure heaters Applications Ambient conditions Heaters evectively prevent the formation of hazardous leakage current caused by condensation. Cool Damp Enclosure heaters are used to prevent the formation of condensation inside the enclosure and maintain a constant minimum operating temperature (e.g. when the system is switched off overnight). They achieve thermal outputs of 10 to 1000 watts. Modern enclosure heaters are equipped with PTC elements.
Enclosure heaters Assembly / electrical connection Installation option for the enclosure heaters The device is attached vertically, i.e. with the connection cable pointing downwards. The connection cable should be tightly secured. In order to create the required convection, a distance of at least 50 mm from components must be maintained above and below the device. The thermal safety clearance from neighbouring components is at least 35 mm.
Enclosure heaters Benefits The prerequisite for optimum conversion of electrical energy into thermal energy is perfect interaction between the thermal output, surface temperature and ambient temperature. Conventional resistor heaters The surface temperature is limited via an additional safety thermostat. As a result, the heater is forever cutting in and out, which means that the continuous thermal output actually produced is low.

Climate control tailored to enclosures Rack-mounted cooling units and fans facilitate direct cooling of electronics by mounting in the 482.6 mm (19˝) level. Other components are also used for optimum routing of cold air inside the enclosure. Rack-mounted climate control All rack-mounted climate control components are mounted on the 482.6 mm (19˝) mounting level for subracks. Because they are positioned directly below the electronic components, effective cooling and the avoidance of hotspots are guaranteed.
Climate control tailored to enclosures Ventilation systems Ventilation systems Ready-to-use, wired modules equipped with fans for numerous Rittal enclosure system platforms offer effective air throughput and minimal assembly work. Fan roofs, fan cross members for server enclosures (door installation), internal fan mounting panels and enclosure internal fans are all available.
Liquid cooling systems Liquid cooling is silent, as well as being 1,000 times more efficient than heat dissipation via air. With this in mind, Rittal offers a range of very innovative and highly effective liquid cooling concepts for industry and IT. Air/water heat exchanger – the classic liquid cooling option for extremely heat and dust-laden ambient conditions. Dissipation of high heat loads without putting thermal pressure on the ambient air.

Liquid cooling systems DCP – Direct Cooling Package/application, assembly Applications: Power electronic components can be cooled particularly effectively using the liquid cooled DCP mounting plate. Heat losses are cleverly dissipated from the enclosure or housing without compromising the high enclosure protection category in any way. Furthermore, liquid cooling is both quiet and 1,000 times more efficient than heat dissipation via air.
Liquid cooling systems CoolingUnit/PanelCooling – Application, assembly Rittal DCP – CoolingUnit Application: The CoolingUnit is available in two variants. As a stand-alone unit with press-fitted cooler tubes, or as an add-on in conjunction with a Rittal Cold Plate. The optional housing for the cooler ensures even more efficient air routing and thus reliable cooling of the air inside the enclosure. Further technical information is available at www.rittal.de/dcp.
Monitoring All the relevant parameters for the function and cooling output of the climate control components are available on the control desk for monitoring and control purposes. Master/slave operation 7 In open bayed enclosure systems which are not separate from one another, cooling units and air/water heat exchangers with Comfort control should always be used. These may be placed in master/slave mode via bus cable SK 3124.
Monitoring Connection example: Master/slave operation Description: The address of the master depends on the number of attached slave units (09 = master with 9 slave units). The address of a slave device always begins with a 1. The second number represents the actual address. Up to a maximum of 9 slave units may be operated with one master unit, whereby any unit may be a master. The maximum overall length of all connected units is 50 m. single-phase and 3-phase units may be connected.
Accessories Regulation/control Digital temperature display/thermostat: SK 3114.100/.115/.024 For installing on the enclosure door or wall and in a cooling unit or heat exchanger. Speed control Temperature-dependent speed control to minimise noise and save energy in part-load operation. Thermostat: SK 3110.000 Especially suitable for controlling fan-and-filter units, heaters and heat exchangers, this thermostat can also be used as a signal generator for monitoring the enclosure internal temperature.
Service International climate control service A central point of contact, decentralised implementation, short response times – this is the successful concept behind our International Climate Service team. High-tech system climate control must offer a permanently high level of reliability in enclosure cooling as well as in machine and process cooling. For this reason, we aim to achieve a maximum global response time of 48 hours.
Service Rittal climate checks Service packages for every aspect of enclosure climate control Load test 482.6 mm (19˝) slide-in equipment which simulates the thermodynamic response of servers allows you to determine in advance whether your cooling system is adequate for any planned extensions. Furthermore, after installing the LCP family, the cooling response can be tested directly, without the presence of a server. Load tests as the optimum basis for planning.
