Racks and components

Refrigeration capacity from 70 to 700 kW

Advanced Industrial Construction

• New generation units
• Designed for high working pressure
• Pressure and vacuum tested units
• Construction codes PED, SVTI, ASME and other on request
• Stainless steel or titanium plates evaporators and condensers
• Automatic oil recovery system

Low ammonia charge

• Thanks to the use of plate heat exchangers, it is possible to achieve very high cooling capacities with a minimum filling of ammonia in the circuit. This type of chillers satisfies the requirement of environmental safety and compatibility and permits to simplify the steps required by the Authorities for the installation and the use of ammonia plants.
• Easy installation
• The chillers are delivered complete preassembled, wired and insulated. The only activities required on site are the power supply to the switchboards and the connection to the solution circuit and cooling media circuit if any.

Low operating costs

• Reduced energy consumption
• Step capacity control which adjusts the refrigerating capacity according to the demand
• Possibility of infinite capacity control by means of inverter (optional)

Cooling capacity from 70 to 1100 kW

Wide application range

• Cooling of unreezable solutions for industrial refrigeration systems. (I.e. H2O and ethylene or propylene glycol, calcium chloride brine, CO2, unfreezable solutions for low temperature up to -45 °C)

• Built-in control and regulation panel with electromechanical or PLC version
• Factory motor prealignment
• Minimised sound pressure and vibration levels

Low operating costs

• Reduced energy consumption
• Possible use of an economizer to increase the capacity
• Infinite capacity control through a built-in slide valve adjusts the refrigerating capacity according to the demand
• Variable Vi control system (option) which, through a built-in slide valve, adjusts constantly the internal volume ratio to the running conditions and ensures the optimal efficiency of the compressor.
