Since 1896: Because experience counts

WITT staff 2006

Unlike our competitors, WITT does not just produce one product group. We can offer you a great variety of solutions precisely tailored to your needs, which will prove their quality and reliability in operation for years.

You can rely on our many years of experience and the professional expertise of our approximately 110 employees.

Leading supplier of industrial refrigeration

WITT has a global reputation as a proven leading supplier with stocks of high-quality refrigerant pumps and highside float regulators. We also supply custom-fit separator solutions, including top-quality, compact pumping stations, evaporator units with plate-in-shell heat exchangers and CO2-cascades for refrigeration plant manufacturers.

Our product philosophy for separator stations has a clear customer focus: high efficiency through reduced assembly time and reduced on-site costs for refrigerant plant manufacturers.

Saving energy, protecting the environment

Our product development always prioritises energy efficiency and protecting the environment. That is why WITT favours natural refrigerants like ammonia (NH3) and carbon dioxide (CO2) since its inception. These refrigerants offer our customers ecological benefits and save them energy.

Using natural refrigerants to protect the environment and promoting sustainable management of refrigeration equipment are important priorities for us, which is why we are active members of the following organisations and initiatives:

Refrigeration Research Council (Forschungsrat Kältetechnik)
DKV - German Society of Refrigeration and Air Conditioning (Deutscher Kälte- und Klimatechnischer Verein)
IIAR - International Institute of Ammonia Refrigeration
VDMA - Association of German Machinery and Equipment Constructors (Verband Deutscher Maschinen- und Anlagenbauer)

worldwide representation

WITT is represented almost everywhere in the world. We are always looking for business partners to expand our network even further, to help maintain our leading role in industrial refrigeration in the future.
