Refcomp SP8H7000 SP8H700E 70HP High Temperature Chiller Reciprocating Compressor
SP8H7000 70HP reciprocating compressor
,SP8H700E high temperature chiller compressor
,semi hermetic refrigeration compressor
- Flexible Capacity Regulation: Equipped with multi-stage capacity control (100%, 75%, 50%), this chiller reciprocating compressor efficiently matches varying system loads to reduce overall energy consumption.
- Precision Crankshaft Assembly: Features precision-balanced crankshafts, connecting rods, and pistons engineered to deliver smooth, low-vibration operation in heavy-duty refrigeration systems.
- Internal Safety Protection: An internal safety valve connects the high and low pressure chambers to maintain safe internal pressure limits and ensure reliable protection during pressure surges.
- Integrated Motor Cooling: The optimized suction channel allows cool intake refrigerant gas to circulate through the motor, ensuring continuous thermal protection and stable continuous duty.

A: Selection requires validating required cooling capacity, target evaporating and condensing temperatures, refrigerant type, power supply compatibility, and the 100%, 75%, 50% capacity steps.
A: Piping design must accommodate the 54 mm (2-1/8") exhaust pipe inner diameter and 67 mm (2-5/8") suction pipe inner diameter to maintain optimal gas velocity and low pressure drop.
A: The built-in safety valve automatically opens if internal pressure exceeds designated safe limits, equalizing high and low sides to prevent structural component damage.
A: Ensure the 230V-200W crankcase heater is powered on before startup to prevent liquid floodback, verify stable supply voltage, and check that starting and operating currents stay within specified limits.
