Corrosion Protection E-coated aluminum-fin coils have an extremely flexible and durable epoxy coating uniformly applied to all coil surfaces. Use offsets in interconnecting lines between 2 condensers and provide isolation where pipes pass through building walls or floors. Consult application engineering for assistance in designing and selecting process systems. but use a similar device. The receiver will become vapor locked under these conditions if re-evaporated gas is not allowed to flow back to the condenser for recondensation. edge coverage. E-coated copper-fin coils have the same flexible and durable epoxy coating as E-coated aluminum-fin coils. Condenser head pressure control Efficient operation of evaporator thermostatic expansion valve requires a 90 F minimum saturated condensing temperature when compressor is operating at 100% capacity. A drop in the entering-air temperature results in a lower saturated condensing temperature. this option combines the natural salt and environmental resistance of all-copper construction with the highest level of corrosion protection. The discharge line should be well supported near the condenser hot gas connection. Specify E-coated aluminum-fin coils for industrial environments with high levels of air pollution. The control works only with single-phase motors. It must be large enough for the liquid to flow to the receiver and. the head pressure control modulates the motor speed of one condenser fan from full to minimum rpm to maintain a constant saturated condensing temperature for full yearround head pressure control. When outdoor temperatures are low enough to cause low condensing pressures. a check valve should be installed in the hot gas line. DOUBLE HOT GAS RISER TO CONDENSER RISER NO. fan cycling control can be applied to one fan to achieve head pressure control. 1 FROM COMPRESSOR Liquid lines • Liquid lines can generally be sized for a 1 to 2° F change in saturation temperature. E-coated coils provide this protection since all coil surfaces are completely encapsulated from environmental contamination. NOTE: Minimum Outdoor-Air Operating Temperature table shows the minimum temperature with fan cycling control and head pressure control. head pressure control is required. This line should be sized so the velocity does not exceed 100 fpm. NOTE: A receiver. The highest point in the discharge line should be above highest point in the condenser coil. Consequently. if used in the system. Unlike brittle phonolic dip and bake coatings. these applications may require switching the set point of the fan cycling control. This option also provides better protection compared to standard or precoated aluminum-fin coils in industrial environments. If the condenser is located where the entering-air temperature could be higher than the enteringair temperature at the compressor location. Specify E-coated copper-fin coils in the harshest combination of coastal and industrial environments. When fan cycling alone will not achieve the required minimum motor speed control is required. 2 RISER NO.Application data (cont) Protect the compressor from liquid refrigerant or oil draining back during compressor off cycles. The use of the defrost thermostat kit (50BB-900---001) also is recommended to sense frost on the evaporator coil if suction temperature drops too low. metal adhesion. allow flow of refrigerant vapor in the positive direction back to the condenser. it is always applied with fan cycling control on the other motor. When units have a lowpressure switch. corrosion resistance. 80 F for 75% capacity. The hot gas line should loop to the floor if the condenser is located above the compressor. so on 3-phase units the motor is changed to a single-phase motor. Process applications tend to have constant heat rejection requirements throughout the year. Generous sizing of this liquid (condensate) line is especially important if the receiver is exposed at any time to a warmer entering-air temperature than the condenser. Liquid lines should be free of any traps or loops. A purge valve should be applied at this point. Units are not qualified for use with Motormaster® speed control. When outdoor-air temperature drops below the minimum temperature listed in the Minimum Outdoor-Air Operating Temperature table on page 29. E-coat provides superior protection with unmatched flexibility. especially if the hot gas riser is long. should be located below the condenser. and the condenser to receiver liquid line must be sized to allow free drainage. most importantly. However. at the same time. The winterstart kit bypasses the low-pressure switch on start-up. On 2 condenser-fan units. • Piping should be routed to avoid excessive strain on system components or the piping itself. When motor speed control is used on 2-fan units. thermal performance and. • Liquid lines should be as small as possible to minimize system change. the use of the winterstart kit (CRWINSTR001A00) is recommended.
