Cleanroom HVAC and Air Handling Equipment
Water-Cooled Condensing Unit
A skid-mounted refrigeration package that transfers cleanroom DX cooling heat into a condenser-water circuit for quiet indoor mechanical-room installation.
- Compact Skid Package
- Water-Side Heat Rejection
- Low Indoor Sound
- Accessible Refrigerant Circuit
Product Introduction
This water-cooled condensing package integrates a scroll compressor, shell-and-tube condenser, receiver, refrigerant accessories and electrical controls on one rigid base. Cooling water removes compressor heat through the condenser while liquid refrigerant feeds a remote DX air-handler coil. The absence of outdoor condenser fans reduces footprint and sound, making the format useful where a building condenser-water loop is already available.
Key Features
Skid piping includes receiver, filter-drier, sight glass and isolation points arranged for service access.
Compact compressor and control placement suits indoor plantrooms with restricted outdoor equipment space.
Removable water-box covers permit inspection of the condenser tube sheet and mechanical cleaning access.
Customer Product Concerns
An indoor condensing package must balance compactness, water-side serviceability and stable refrigerant delivery to a remote evaporator.
Outdoor equipment space or allowable sound is limited.The unit rejects heat to building water and operates without large condenser fans.
Condenser tubes gradually collect scale or suspended solids.A removable end cover provides direct tube-sheet access for inspection and cleaning.
Field-built refrigeration skids create inconsistent component layouts.Factory assembly places the compressor, receiver, controls and service valves on one tested structural base.
Variable condenser-water temperature can destabilize head pressure.Water-flow control and refrigerant safeties maintain an appropriate condensing range as the loop changes.
Typical Applications
Hospital cleanroom air handlersHigh-rise laboratory HVACPharmaceutical plants with central cooling towersIndoor process-cooling skidsNoise-sensitive clean manufacturing facilities
