REFRIGERATOR - HEATER UNITS SINGLE CIRCUIT



In the standard production these liquid chillers single circuit are composed by:

  • Semi-hermetic motor-driven piston or screw compressor with power ratings ranging from 15kW to 300kW
  • Insulated stainless steel plate evaporator for cooling water and anti-freeze mix
  • Forced-air condenser
  • Electrical control box with electronic coolant temperature control
  • Insulated coolant storage tank with fittings and full discharge valve
  • Motor-driven centrifugal pumps(two for standard models, one of which is for the recirculation of the coolant from the tank to the evaporator and the other one for the users: "SP" plate or "SM" coaxial exchangers, heat-conditioned tanks, ventilated batteries for cooling the premises or cold stores, etc.)
  • Monobloc structure on stainless steel sections and containment panelling made of finely-glazed or satin-finished AISI 304 stainless steel sheeting

Standard working range: +45°C to -10°C.

These models can be provided with touch-screen control and management, equipped by:
- PLC with designed software, for the management of the system
- colored back-lighted touch-screen user interface for a simple and intuitive management and control of the chiller
- possibility of changes on the logical operation of the system by PLC software update, without perform changes on the electrical connections

The use of these chillers are numerous and can be used for many works, for example to temperature control and stabilization of foodstuff before or after the packaging, to air-conditioning environments, to conditioning medium and low temperature cold stores(+7°C -30°C), to cooling tunnels for oven-baked products or to froze food, to cool down the temperature of vapors, to cool down distilling plants, to cool down cutting or pneumatic oil for machine tool, etc..

The Serie ZG liquid chillers can be matched with other machinery that we produce: heat exchangers, accumulation and pumping units, integrated temperature control systems and/or plants.

Our refrigerator-heater units "Serie ZG" can be designed on customer request.

Our liquid chillers are supplied fully-tested, with "CE" certification, with instruction and maintenance manual and gas-filled with ecologic refrigerant.
