Air Chiller Water Cooled

Air Chiller Water Cooled

Advantage
  • Air Chiller Air Cooled is used to supply a cooled air ring of blown film extrusion line. Cooling of air with the help of direct expansion of refrigerant saves energy compare to conventional water chiller plus heat exchanger system
  • Air Chiller Air Cooled provides consistent air temperature irrespective of ambient condition which is very essential for processing of plastics on blown film lines
  • Five SAC series chillers have cooling capacity of 9.4 TR to 28.5 TR with operating temperature of 5°C to 20°C in ambient air temperature up to 40°C
  • Compact in size which reduce foot print up to 25% compare to conventional water chiller plus heat exchanger system
Unique Features
  • Energy efficient & reliable scroll compressor with hermetically sealed suction gas cooled motor
  • Each model is equipped with PLC based platform. Control features include 2 line 16 character LCD display, onboard fault indication with audio alarm
  • Accurate temperature control with the help of modulating hot gas bypass valve
  • Intelligent program to save energy for dual compressor chiller circuit (SAC 40 SAC 55 & SAC 80) specifically for part load application
  • Display of set value and actual value on the screen
  • Display of return air temperature on screen
  • Scroll and function buttons allow your to navigate the chiller's control platform
  • Tool free access panel with neatly organized internal component layout. Simply remove the panel to get the access of entire cabinet of the chiller
  • Proven component supplier i.e. Copeland, Danfoss, Siemens, Emerson, EBM, IFM have been chosen for ultimate reliability and availability
  • All chillers are factory tested under load prior to shipment
  • Condenser fan blade, motor, nozzle and guard are a single pece assembly for improved reliability with the fan motors having rugged external rotor design
  • Finned & Tube Condenser - high surface area due internally grooved copper tubes, generously sized for industrial environment and tested to 500 PSIG
  • Finned & Tube Evaporator - high surface area due internally grooved copper tubes, generously sized for industrial environment and tested to 300 PSIG with lower pressure drop
  • RTD Temperature sensor yield higher precision and repeatability then thermocouples
  • Three phase monitor protects against unit damage due to phase reversal or loss of phase
Options
  • Refrigerant pressure gauges
  • Eco friendly refrigerant - R407c
  • Air filter at the inlet of evaporator
  • Air filter at the inlet of condenser
  • Condenser fan cycling - regulates chiller capacity when the ambient air temperature is below the normal design temperature
  • SCADA communication
