Evaporator units

You decide, we have the solution.

WITT evaporator units are always the right solution when the refrigerant should be limited to the machinery room and a secondary refrigerant pumped to the coolers (indirect refrigeration). WITT installs either fully welded or semi-welded evaporators in evaporator units with a flooded design. Of course, all heat exchangers from recommended brand names. The selection of a suitable heat exchanger is not only depending on the application and operating conditions. We are happy to support you.

According to your individual requirements you decide quite flexibe any additional equipment for your evaporator unit, i.e.:

  • Stop valves
  • Overflow valves
  • Service valves
  • Automatic fast acting valves
  • HR and HS high-pressure float regulators
  • NGX maximum level switch
  • Stand pipe with level control
  • Differential pressure piping incl. pressure gauges and
  • WITT oil management

The positioning of connections on the pressure vessel for inlet and outlets can be chosen according to your needs taking into account the technical feasibility
