SCW Staged Multi-Ton Chillers

Air Conditioning From 48K to 900K BTUs

Staged Chilled Water (SCW) units are available in capacities ranging from 48,000 (4-ton) to 900,000 (75-ton) BTU/hr. SCWs are available in 1 or 3 phase, 50Hz or 60Hz, and all standard voltages (208, 230, 380, 460).

Multiple compressors and refrigerant circuits are incorporated to provide minimal power consumption versus load demands, as well as redundancy throughout the unit. Each refrigerant circuit is hermetically sealed and factory pre-charged with R-22.

Each condensing unit is monitored and protected with freeze controls, high limit switches, high and low aquastats, timers, and on-board fuses or breakers.

Seawater side of condenser coils are made of cupronickel, and refrigerant shells are copper (NOT steel) for maximum efficiency and corrosion resistance.
Compact copper brazed, stainless steel plate exchangers are designed for maximum efficiency in a confined space.
Computer matched components provide maximum cooling/heating capacity.
All chillers use thermal expansion valves (TXV). Unlike the capillary tubes, TXVs automatically adjust to changing load requirements to maintain optimum performance.
Each stage is individually protected by a circuit breaker, flow switch, freeze protection, water temperature high limit, high pressure refrigerant switch, and low pressure refrigerant switch. These safeties are in addition to the compressor thermal overload.
Compact base design provides flexibility in engine room layouts.
Multiplexed modules offer precise BTU requirements for any application.
