Introduction de produit

The scroll compressor chiller combines several hermetic scroll compressors in independent or paired refrigerant circuits. Each orbiting scroll compresses gas continuously with few moving parts, producing low vibration and a compact enclosure. Compressor staging matches part-load demand in small increments, and a circuit can remain off or be serviced while other circuits operate. Air-cooled versions use condenser fans and finned coils; water-cooled versions use a compact condenser connected to a water loop.

Key Features

Multiple scroll compressors create smaller operating steps than one large fixed-capacity compressor.

Hermetic construction and continuous compression reduce external shaft seals and vibration.

Independent circuits maintain partial cooling when one circuit is unavailable.

Compact compressor dimensions support packaged chillers and modular plant layouts.

Préoccupations du client produit

Scroll chillers rely on coordinated staging and adequate water volume to prevent excessive starts under light or rapidly changing load.

The chiller cycles when the active process load is smaller than its first capacity step.Multiple smaller compressors and appropriate buffer volume lengthen operating cycles.

Simultaneous compressor starts create a large electrical demand peak.Timed staging starts compressors sequentially as leaving-water demand increases.

One refrigerant leak removes the entire cooling plant.Independent circuits isolate the affected section while remaining circuits continue.

Condenser fouling raises pressure and trips compressors during hot weather.Accessible coil faces and staged fan control maintain design condenser airflow.
