Carrier 5H open-drive reciprocating Compressor

Automatic unloaded starting, so expensive high torque motors are unnecessary, reducing the initial expense. The high-efficiency motor can further increase the efficiency of Carrier 5H and Carrier 5F compressors. The crankcase casting, cylinder head, and valve plate designs allow for a smooth, unrestricted refrigerant flow. A refined, two-piece shaft seal assembly virtually eliminates seal leakage for maximum reliability over a wide temperature range.

The efficient crankcase heater design prevents the accumulation of liquid refrigerant in the crankcase during a shutdown and dilution of the compressor’s oil supply. As suction pressure changes, capacity control automatically reduces compressor capacity to as low as 35% of full-design load, reducing horsepower requirements as demand changes. Part-load operation increases energy efficiency, reducing utility bills.
