DIP AND FLOW COOLERS USER’S MANUAL Introduction Please read all the information in this booklet before using the unit. Warning HIGH TEMPERATURES ARE DANGEROUS: they can cause serious burns to operators and ignite combustible material.
DIP AND FLOW COOLERS USER’S MANUAL Introduction Veuillez lire attentivement toutes les instructions de ce document avant d’utiliser l’appareil. Avertissement DANGER DE TEMPERATURES ELEVEES : les opérateurs peuvent subir de graves brûlures et les matériaux combustibles risquent de prendre feu.
DIP AND FLOW COOLERS USER’S MANUAL Einleitung Bitte lesen Sie diese Bedienungsanleitung komplett bevor Sie dieses Gerät benutzen. Warnung HOHE TEMPERATUREN SIND GEFÄHRLICH: sie können dem Bediener ernsthafte Verletzungen zufügen und brennbare Materialien können sich leicht entzünden. Techne hat bei der Konstruktion dieses Gerätes sehr darauf geachtet, daß der Bediener vor Gefahren geschützt ist.
DIP AND FLOW COOLERS USER’S MANUAL Introducción Le rogamos lea cuidadosamente la información contenida en este folleto antes de manipular el aparato. Aviso LAS TEMPERATURAS ELEVADAS SON PELIGROSAS: pueden causarle graves quemaduras y provocar fuego en materiales combustibles.
DIP AND FLOW COOLERS USER’S MANUAL INTRODUCTION Read the whole of this book before commencing work with the unit. The book applies to a range of Techne fridge units, Dip Coolers RU200 and RU-500 and Flow Coolers FC-200 and FC-500. Hence paragraphs or sections without a heading or reference apply to all units while paragraphs or sections with headings apply to specific units. For Refrigerated Baths there is a separate booklet.
DIP AND FLOW COOLERS USER’S MANUAL Flow Coolers The FC-200 and the FC-500 are designed to work with the Techne C-85 circulator to give the temperature control. They are normally used to give circulation round a closed loop system, but may also be used in the open tank situation where the use of a dip cooler is impractical. The Flow Coolers use a refrigerant which is circulated through a compact heat exchanger which has inlet and outlet pipes for the working liquid on the rear of the unit.
DIP AND FLOW COOLERS USER’S MANUAL Specification The minimum temperatures quoted in the specification are achieved in an ambient of 20 oC with the appropriate liquid in a well insulated 8 litre bath. However many things will affect the minimum obtainable temperature, such as: ambient temperature, insulation and length of circulation system, condition of the working liquid, heat input and so on.
DIP AND FLOW COOLERS USER’S MANUAL Siting Considerations All the units are air cooled, air being pulled in through the front and expelled from the rear. The ventilation grilles should never be obstructed, therefore, as this will detract from the performance. Also the fridge units should never be situated in an enclosed space or near an extractor fan, this too will detract from the performance. MINIMUM 150 mm (6") MINIMUM 150 mm (6") Setting up the unit 1.
DIP AND FLOW COOLERS USER’S MANUAL 2 Recommended liquids: When working at low temperatures always use a liquid suitable for the lowest temperature at which the unit is capable of achieving, see the list of recommended liquids below. When using a flow cooler up to 30oC in an enclosed circuit use the recommended liquid.

DIP AND FLOW COOLERS USER’S MANUAL Carrying a Dip Cooler A support clip is provided which should be fixed to the side of the unit if it is required to move the unit frequently. It not only makes it easier to carry it also protects the flexible hose. The support clip consists of a block and a long screw. To fit it to the Cooler, remove the screw in the cover at the rear on the opposite corner to the coil, the long screw goes through the block and replaces the screw just removed.
DIP AND FLOW COOLERS USER’S MANUAL OPERATION Precautionary Measures 1 Do not operate any of the fridge units without liquid in the circuit. Ensure that the evaporation coil on the Dip Cooler is covered. Ensure that the heat exchanger in the Flow Cooler is full. 2 Freezing may occur if there is insufficient circulation or the incorrect liquid is used. While this will not harm the unit some time may pass before the unit can be used again.
DIP AND FLOW COOLERS USER’S MANUAL Daily Maintenance As mentioned earlier, it is imperative that the air flow is not impeded in any way. It is important that the grilles are kept clean and clear at all times. Even dust and fluff can impair the performance, therefore the units must be used in a clean environment or they should be regularly cleaned.
DIP AND FLOW COOLERS USER’S MANUAL Service 1 Complete servicing and repair of Techne products is available at Techne see the contact information on pages 3 or 4. 2 A Service Manual is available and servicing may be undertaken by any competent refrigeration engineer.
DIP AND FLOW COOLERS USER’S MANUAL ADDITIONAL INFORMATION Brief fault finding notes and lists of accessories are given in this section. NOTE THAT THIS EQUIPMENT SHOULD ONLY BE DISMANTLED BY PROPERLY TRAINED PERSONNEL. REMOVING THE OUTER COVERS OR BASE EXPOSES POTENTIALLY LETHAL MAINS VOLTAGES AND A FAN. THERE ARE NO USER SERVICEABLE PARTS WITHIN THE EQUIPMENT.
