Ultra-low temperature units

As a solution provider, we design each individual system for the respective application and the temperature level to be achieved. Standard solutions have no place here. Depending on the requirements, compressors may be configured in two stages or as a multi-stage cascade. In addition to air and classic cooling media, other circulating media such as glycol mixtures, brines or thermal oils, can also be cooled. For shock freezing of sensitive, active pharmaceutical ingredients, we have developed our own system technology in the form of our plate freezer.

L&R deep-freeze systems are always designed individually. In addition to reliability, energy efficiency and sustainable operation of the system over its entire lifespan are of key importance.

The choice of refrigerant also has a tremendous impact on these factors. As a matter of principle, only refrigerants that work particularly reliably and efficiently, and use of which readily complies with all applicable legal requirements (such as the F-Gas Regulations) are used. In addition, other factors, such as flammability, toxicity and explosion risks, are taken into account.

L&R uses conventional safety refrigerants, as well as natural refrigerants with very low Global Warming Potential (GWP) values, such as ammonia, propane, propene and CO2. L&R has gained extensive experience in this field over many years.

Since the machines are almost exclusively used in production, very high availability through the use of high-quality components from renowned manufacturers is top priority. Should it nevertheless become necessary, we are, of course, at your disposal for service, maintenance and repair. This can be done “just in time” in the event of an emergency, as our service hotline with competent staff is available 24 hours a day, 7 days a week.
