5H

The 5H by Trelec is an Open-Drive Reciprocating Compressor designed for versatile use in air conditioning and refrigeration systems. It supports both belt and direct drive configurations, allowing for flexible integration into various system designs. This compressor is compatible with common refrigerants including R-134a, R-404A, and R-407C.

Key features include automatic unloaded starting, which eliminates the need for expensive high-torque motors, reducing initial costs. The design incorporates a refined two-piece shaft seal assembly for enhanced reliability and an efficient crankcase heater to prevent liquid refrigerant accumulation. Capacity control is automatic, reducing compressor output to as low as 35% of full-design load based on suction pressure, which improves energy efficiency and lowers utility bills during part-load operation.

The compressor is available in various sizes, with nominal horsepower ranging from 25 to 150 HP and nominal capacities from 92 to 346 cfm. Physical dimensions and operating weights vary by model size, with options ranging from 31 inches in length and 610 lbs for the smallest size to 47 inches in length and 1,580 lbs for the largest.

This compressor is suitable for building custom systems or as part of a complete marine condensing unit offered by Carrier. Its robust design ensures positive pressure lubrication through a large-capacity oil pump and an integrated oil-filtering system, extending the operational life of the unit.
