The IMI Hydronic Engineering Germany GmbH is a company of heating technology developed, heating valves, produces and markets worldwide. It is based in Erwitte, North Rhine-Westphalia .
history
The company was founded in Lippstadt in 1928 by the engineer Theodor Heimeier. He first set up a production line for raw and finished parts, which produced pressed and cast parts made of brass for general valve construction. After the company's founder died in 1946, the company began specializing in heating fittings in the 1950s and began building a gunmetal foundry in 1952 ; In 1965 the company moved to Erwitte, 6 km away. There was the launch of the radiator regulating valve Mikrotherm formed by a liquid-filled 1969 thermostatic valve has been added. The global oil crisis sharpened the focus on energy-conscious systems and paved the way for the increasing demand for thermostats and heating fittings.
In 1980 it was therefore possible to set up representative offices in Canada, Australia, Japan and the Far East as well as in the USA; the production facilities in Erwitte have been continuously expanded since 1960. In 1995 the company was taken over by the IMI plc group.
The company generated € 100 million in 2010, 70% of which in Germany and employed 400 people, including 31 trainees.
Products
Initially, the production of gas shut-off valves (1935) and, increasingly, heating fittings began. The Mikrotherm regulating valve formed the core business in 1959 and was further developed in 1969 into a liquid-filled thermostatic valve for which a patent was pending. In 1980 a total of 50,000 valves left the foundry every day.
The thermostatic valve forms the core area of the company today and has therefore been continuously developed. There are currently 120 different valve bodies and 40 different thermostat heads. There are valves for reverse flow direction, reverse effective direction, particularly low-resistance valves as well as designs for all types of radiator connection and authority models . In addition to the setting positions 1–5 for the room temperature, the thermostat heads have optical markings for frost-proof operation and night setback as well as tactile grooves which make operation easier for the visually impaired. Transition pieces enable the attachment of thermostatic heads from competing products.
Other products include a. thermal actuators for underfloor heating and for heating, ventilation and air conditioning systems, room thermostats, special fittings, balancing valves for hydraulic balancing and overflow valves .
With the advent of data transmission, radio and bus systems were developed.
