High Quality Components • Seawater side of condenser coils are made ofcupronickel, and refrigerant shells are copper(NOT steel) for maximum efficiency and corrosionresistance.• Compact copper brazed, stainless steel plateexchangers are designed for maximum efficiency in a confined space.• Computer matched components provide maximumcooling/heating capacity.• All chillers use thermal expansion valves (TXV).Unlike the capillary tubes, TXVs automaticallyadjust to changing load requirements to maintain optimum performance.• Each stage is individually protected by a circuitbreaker, flow switch, freeze protection, water tem- perature high limit, high pressure refrigerant switch, and low pressure refrigerant switch.These safeties are in addition to the compressor thermal overload. Innovative Design • Compact base design provides flexibility in engineroom layouts.• Multiplexed modules offer precise BTU require-ments for any application.• Lightweight, aluminum construction enhancesease of installation while providing corrosion resist- ant durability.• Complete control circuit provides multiple fail safesfor system protection.• Vertically mounted units are available. Individual Refrigerant Circuits • Redundant design assures cooling if one circuitmalfunctions. Serviceability • All compressors accessed from front of condens-ing unit ensuring easy change out. Quality Assurance • Each unit is pre-charged, load tested and calibrated at the factory• Charge Guard
® protection provides sealed accessports, ensuring environmental protection and sys-tem integrity.• All units meet or exceed applicable ABYC andU.S.Coast Guard regulations.

Product Description The staged Chilled Water Units are available in capacities ranging from 48,000 to 900,000 BTU/H.SCWs are available in single phase or threephase, 50Hz or 60Hz, and all standard voltages (208, 230, 380, 460 VAC).Multiple compressors and refrigerant circuits are incorporated to provideminimal power consumption versus load demands, as well as redundancy throughout the unit.Each refrigerant circuit is hermetically sealed and fac-tory pre-charged with R-22.Each condensing unit is monitored and protected with freeze controls, high limit switches, high and low aquastats, timersand on-board fuses or breakers.All access ports to the refrigerant system are protected with CHARGE GUARD
® , a factory installed seal, ensuring system integrity from shippingthrough final installation.Condenser coils are constructed with cupro-nickel to provide high corrosion resistance.Unique stainless steel evaporator plates are designed for max-imum efficiency of heat transfer.SCW’s can be built with circulation pump mounted in the chiller frame.Frames are welded with marine grade aluminumalloy, primed, then finished with a corrosion resistant epoxy.These condensing units can be installed in any convenient location and are highly resistant to vibration, moisture or ambient temperatures up to140°F/60°C.Units meet or exceed Coast Guard regulations.
