NH3-CO2 cascade systems
mashav3.gif The WITT cascade systems will be made according to customer specification in our work-shop in Aachen (Germany) incl. all pipe work. After the pre-assembling and pressure test, the system will be divided into parts for the transport to our customers around the world.

Here is an example of a three-stage cascade NH3/CO2 with a cooling capacity of 2 x 330 KW, with a NH3 evaporation temperature to = -32 ° C and a CO2 condensing temperature of tc / o = -28 ° C. In this plant, CO2 is used as an evaporating brine.
