For any application the right solution

You decide, we have the solution.

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

Pumping stations

WITT pumping stations are perfectly matched assemblies for systems with direct refrigeration. In addition to a high-efficient integrated separator system, a pumping stations is equipped with a certain amount of pumps to meet the capacity requirements. The station comes with downlegs and delivery piping incl. differential pressure piping and overflow line.

Evaporator stations

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.

CO2-Cascade systems

WITT CO2-Cascade systems are a future-proof, sustainable solutions using the benefits of the refrigerant CO2. In the WITT workshop in Aachen we will build cascade system according to your individual needs and deliver it with all required components, such as refrigerant pumps or plate heat exchangers. For fast and easy installation on site we pre-assemble and align the entire cascade and certify it in one unit.

Of course we look at the relevant conditions of your refrigeration system to match all the components for trouble-free operation.
