Introduction The square, compact design of the Model P and rectangular Model S allow easy handling and installation. In most cases, only one person is needed to carry a unit. What’s more, the Model P can be stored standing on end. This means several units can be loaded on a single skid for moving from one point to another. Yet, the benefits of this compact design go beyond ease of installation. They continue with attractive styling.

Features & Benefits Features & Benefits: Overview Trane propeller unit heaters feature the largest selection of standard sizes from any line in the industry. In fact, vertical Model P and horizontal Model S unit heaters provide enough ‘off-the-shelf’ selections to fit almost any application. The versatile two-in-one Model P is available in 15 sizes with capacities from 41.3 MBh to 705.6 MBh. The companion standard and bypass Model S is available in 23 sizes with the capacities from 8.0 MBh up to 360 MBh.

Features & Benefits Steam Pressure Control SPST switch opens on a rise in pressure. Control is automatically reset, has a range of 0 to 15 PSIG (0 to 103 KPa) and has an adjustable differential. Other actions, ranges, circuits and manual reset models are available on request. Manual Starters Single and three-phase models are available. Standard models are single-speed, toggle-operated, NEMA Type 1 and are surfacemounted.

Application Consideration General Rules In locating or spotting Trane Propeller Unit Heaters – either the Model S Horizontal or Model P Projection Unit Heater – the following general rules should be considered. 1. Spot units at points of greatest heat loss. Blanket outside doorways effectively and provide ample coverage for exposed window areas. 2.
PAGE 8
Application Consideration increase the downward projection of heat by as much as 45% over units without diffusers. Model P Units with the Louver Cone Diffusers can also be used to blanket doorways effectively, as shown in Figure 2 by simply adjusting half of the louvers vertically, and half closed. Model S horizontal-type units are ideal for mounting in plant areas where ceilings are low.

Selection Procedure Trane Propeller Unit Heaters Both Model S and Model P Propeller Unit Heaters are ideally suited to such a wide variety of installations that there can be no hard and fast rules regulating their selection. In determining the type and size of the units for any building, the following points are generally considered: BTU Requirements While the choice of units depends upon several important factors, the total Btu requirement is usually determined first.
PAGE 12
Selection Procedure Formula The following formula is used to arrive at final air temperature volume when 70 F (Standard Air Basis) is known or vice versa: Table 1. Max. Mounting Heights and Distance of throw for Model S Units (based on 2 lbs Steam Pressure 60F entering Air) Cfm at final temp.
PAGE 13
Selection Procedure obtained by equipping these units with Louver Cone Diffusers. The individually adjustable blades of the Louver Cone permit an infinite variety of adjustments to meet any on-the-job problems. By setting the blades vertically to straighten the airstream, as much as 45% increase in throw can be obtained. 4. Solution: Under 40 F and across from 30 lbs. in Table 2, find the factor 1.51. Hot Water Selection Example 1. Equivalent capacity of required unit at 2 lbs.

Performance Data Technical & Mounting Data Horizontal Unit Heaters Technical Data The performance data listed in Table 13, Table 14, and Table 15 include sound ratings. The ratings provide a guide in determining the acceptable degree of loudness in particular occupancy situations. Certain general rules apply to specific selection of unit heaters with regard to degree of quietness (or loudness); • The greater the fan diameter, the higher the sound level.
