RC2-790B-Z 276HP Screw Refrigeration Compressor For Rack System

Engineered for large cold storage warehouses, food processing lines, and commercial water chiller packages, the RC2-790B screw refrigeration compressor provides continuous duty under demanding operating conditions. At 50Hz, it runs at 2950 rpm to move a displacement of 791 m³/h, which increases to 952 m³/h at 60Hz. Designed to work with common working fluids including R134a, R22, R407C, R404A, and R507A, this unit handles heavy heat loads while keeping discharge temperatures within safe operating limits.

In industrial cooling installations, operating at full load during off-peak hours leads to unnecessary power expenses and premature mechanical wear. The RC2-790B screw refrigeration compressor resolves this issue by incorporating internal slide valves that support 4-step capacity control (30%, 50%, 75%, 100%) and continuous stepless modulation from 25% to 100%. Matching displacement directly to real-time cooling demands lowers energy draw during partial-load cycles while keeping cold room temperatures consistent.

Featuring a 5-to-6 asymmetric rotor profile housed inside a heavy FC25 cast iron body, this screw refrigeration compressor resists structural deflection during high-pressure operation while reducing running vibration. Internal motor cooling channels pass incoming suction gas over the stator coils to remove heat before compression. Built-in PTC thermistors continuously monitor winding heat and discharge gas temperatures, working with electronic protection modules to stop operation if thermal limits or phase imbalances occur.
