cycle is 50% (75% is preferred). If the compressor cannot be unloaded then a hot gas bypass to the
suction line must be installed. See Figures 3-11 through 3-14.
Cooling Tower (optional).
When selecting a cooling tower, careful attention must be given to
operating wet bulb conditions. It is advisable to check with your local cooling tower distributor for
their recommendations based on actual operating conditions in your area. An average wet bulb of
78
°
F is typical in the U.S., but many localities have designed wet bulbs as low as 72
°
F or as high as
82
°
F.
The cooling tower water pump must be capable of delivering the required volume of water through
the condenser. Due to cooling tower location and pressure drop through water lines and regulating
valves, the water pump must be sized for each installation. Table 3-3 shows the total heat rejection,
in 1000 BTU’s per hour for the P34AL-15 and P34ALOF-15 at different suction temperatures. The
water piping for the cooling tower and the installation of the pump must be in accordance with the
manufacturer’s instructions. Caution must be used to prevent the condenser water pump from losing
prime during off cycles.
Proper water treatment for the prevention of mineral and foreign matter accumulation in the
condenser or cooling tower is recommended. A water analysis should be obtained to determine the
proper chemicals to use. The use of a 40 mesh strainer in the condenser water supply line is also
recommended.

Total Heat Rejection is based on pulldown of 105
°
F SDT and are nominal values based on open drive
reciprocating compressor.
Consult factory for condenser sizing if desired.
TABLE 3-3
Total Heat Rejection (MBH)
The condenser water pump should be sized on GPM required for condenser at 80 ft. total discharge
head for a typical installation. However, due to cooling tower location and pressure drop through
water lines, the water pump should be sized for each installation.
