Water-Cooled

Central Chillers (MW Series)

5 to 180 Tons Capacity








The MW Series Central Chiller provides precise temperature control 
from an economically affordable and reliable unit. Perfect for plastic injection 
molding, blow molding, extrusion and other industrial applications.



Features:
  • 5 to 180 Tons Capacity
  • Multiple refrigerant Zones
  • Water-Cooled Condenser
  • Process Temperatures from 20 F to 65 F
  • Galvanized Steel Frame
  • Nema 12 Electrical Cabinet
  • Coolant flow switch and freezestat safety
  • Sight glass with moisture indicator
  • Removable condenser caps for easy service
  • Excellent for start-up installation or expansion of current systems

The water-cooled condenser has removable caps and  compressor suction/discharge valves for easy access and servicing. A brazed plate evaporator provides efficient heat exchange.  The galvanized steel frame offers a sturdy construction. 

Controlled by a mechanical thermostat, the MW Series central chiller includes a coolant flow switch, coolant freezestat, compressor motor overload protection, refrigerant high and low pressure switches, and a refrigerant pressure release valve for safety.

The 5 - 40 ton single zone, 20 - 80 ton dual zone, and 90 - 120 ton triple zone models are equipped with a braze plate evaporator.  Shell and tube evaporators are on the 5 - 40 ton single zone, 100 - 120 ton dual zone, and 90 120 ton triple zone models. Condenser manifolds are on all dual and triple zone with single supply and return ports.

Hermetic scroll compressors on 5 - 30 ton single zone models and 20 - 60 dual zone models. Semi-Hermetic compressors used on 35 - 60 ton single zone models, 70 - 120 ton dual zone models, and 90 - 180 tone triple zone models. Dual and triple zone compressors are staged individually. 

All single zone models are controlled by a mechanical thermostat.  A microprocessor-based multi-zone thermostat controls all dual and triple zone chillers.

Water-cooled models are recommended where adequate condensing water supplies are available from tower or city water sources.
