Water Chiller (Air Cooled)

Water Chiller (Air Cooled)

New SCA series portable chillers are quality engineered for year-round, 24 / 7 operation under demanding industrial applications. Combining a compact design, durable construction and a new control platform, SCA chillers will provide maximum cooling for your application.

SCA series chillers have cooling capacity of 3.1 TR to 59 TR with operating temperature of 8°C to 30°C in ambient air temperature up to 40°C.

Unique Features
  • Microprocessor / PLC based control
  • Energy efficient & reliable scroll compressor with hermetically sealed suction gas cooled motor
  • High performance, low maintenance system with switching cycle control
  • Crank case heater to prevent liquid migration of refrigerant in compressor
  • Filter dryer to ensure moisture free system
  • Sight glass with moisture indicator
  • Large size stainless steel insulated tank to prevent heat loss
  • Dry running protection of pump by water level sensor in the tank
  • Water re-feeding valve to maintain level in the tank automatically
  • Antifreeze thermostat for protection of evaporator and compressor
  • High volume, high pressure pump with stainless steel impeller
  • Inbuilt process water bypass with valve
  • All chilled water contact surfaces are non ferrous for protection against corrosion
  • All wetted surfaces are stainless steel, copper or other non ferrous material
  • Proven component suppliers like Danfoss, Copeland, Grundfos, Ebm, Siemens have been chossen for ultimate reliability
  • Tool free access panels and a neatly organized internal component layout provide easy access and service. Simply remove the panels to gain access to the entire cabinet of the chiller
  • All chillers are factory tested under load prior to shipment
  • Condenser fan blade, motor, nozzle and guard are a single piece assembly for improved reliability with the fan motors having rugged external rotor design
  • Finned & Tube condenser - high surface area due internally grooved copper tube, generously sized for industrial environment and tasted to 500 PSIG
  • Brazed Plate Evaporator / Shell and Tube Evaporator - provide higher heat transfer coefficients due to reduced fouling
  • Evaporator Stainer - protects the evaporator from solid contaminants in the process water stream
Control Feature
  • Large, dual 4-digit LED displays for process data, alarms and operation
  • Scroll and Function buttons allows you to navigate the chiller's control parameters
  • Selectable temperature control point choose between to process, from process or average
  • Five status lights that show pump, compressor, alarm and units selection status
  • Control on No. of compressor on / off cycles
  • On board test facility of all input / outputs
  • Temperature deviation alarms for precise control on water temperature
  • Display of set value and actual value on the screen
  • Display of return water temperature on screen
  • Display of total run - hour time of compressor / pump
  • RTD Temperature sensors yield higher precision and repeatability than thermocouples
  • Three phase monitor protects against unit damage due to phase reversal or loss of phase
Refrigerant Options :
R 22 - Standard / R 134a / R 407c
