For any application the right solution

Refrigerant storage, efficient separation, refrigerant pumping or heat exchange.

In a refrigeration system the refrigerant must be stored and its liquid and gas phases separated (separation). Pressure vessels with integrated separation equipment are used for this purpose. Receivers for refrigerant are also needed at locations of the refrigeration system.

WITT can offer you the ideal solution for all applications. Whatever you need, either just a receiver, a surge drum, a cascade system or a complete unit with refrigerant pumps or plate evaporators:

We design and build sophisticated pressure vessels and complex units to meet your individual requirements, using all our experience. On-site you just have to connect the pipework and electrical wiring.

At WITT pressure vessel units are manufactured according to PED with the AD2000 regulation and delivered with the required CE documentation. This saves additional certification on site.

Flexible according to your needs

For the WITT pressure vessel units the following components are available:

  • semi-welded plate heat exchangers (i.e. Alfa Laval or Thermowave)
  • Fully welded plate heat exchangers (i.e. Vahterus)
  • WITT stainless steel standpipes
  • WITT oil recovery system
  • WITT NGX maximum level switch
  • Stop valves (i.e. AWP or Parker Herl)
  • Electronic level indicator (i.e. RTK)
  • Pre-piped assemblies (i.e. oil traps)
  • Insulation
