Water-cooled process liquid chiller - nominal cooling capacity 12.4 - 191.7 kW

The basic unit includes: electronic expansion valve, storage tank, phase monitor and compressor crankcase heater. With pump and condensation control valve.

It is the optimum solution for all industrial applications requiring high performance, continuity of operation and reduced running costs.

Technological innovation, reliability and customer satisfaction have made us a leader in the industrial refrigeration market for 40 years. The result of careful research, Frozen units are specifically designed for Process Applications and are equipped with a standard tank and pump to simplify installation.

The innovative configuration with the evaporator submerged in the tank reduces heat loss to the outside and ensures excellent temperature stability of the process fluid even with highly variable thermal loads.

The use of top brand components and the testing of all units ensure high levels of reliability, minimising the danger of downtime. The numerous accessories available, combined with one of the widest operating ranges on the market, make the Frozen perfectly suited to the specific requirements of a wide variety of industrial applications.
