2022 High quality Highly Hitachi Compressor - RefComp Piston Refrigeration Compressor Series SP series SP6H4000 – Hengyi

RefComp Piston Compressor Flexibility For A Wide Range Of Applications

SP Series

This series can be used with R22, and with the chlorine-free refrigerants R407C, R134a, R404A and R507 as well without making it necessary any mechanical changes.

Developed specifically for air-conditioning and refrigeration applications at mid or low evaporating temperatures, this range can work up to 80 [°C] condensing temperature with R134a and down to -40 [°C] evaporating temperature with R22 or R404A or R507.

It is available either with “full size” (H) electric motors – for air conditioning systems – or with “small size” (L) electric motors – for refrigeration systems.

SB Series

Two-stage semi-hermetic reciprocating compressors, suitable for R22, R404A-R507 refrigerants.

To further improve the efficiency of the compressor, it is possible to install a subcooler (as option – already fitted or not). This way the gas contained in the intermediate chamber is cooled down by the injection of liquid refrigerant before the second compression stage occures.

The lubrication is assured by an oil pump and a Venturi internal oil recovery system. It is protected by a high efficiency oil filter and can be monitored by means of differential pressure switches.

Electrical motor provided with an electronic protection device based on temperature control and generously selected to grant the best performances, safety and reliability.

Suction and discharge plate equipped with reed valves and made of specific materials for low temperature applications.
