About Kreutzträger Kältetechnik
Kreutzträger Kältetechnik Schweiz AG is part of the owner-managed Kreutzträger group of companies based in Bremen, which has been planning, building and servicing industrial and commercial refrigeration systems since 1960. Since its founding, more than 500 new large-scale industrial systems have been realized, predominantly using the natural refrigerants ammonia (R717), carbon dioxide (R744) and propane (R290). The range of services covers plant construction and engineering, industrial and commercial refrigeration, air conditioning technology, fruit and vegetable cold storage rooms with ULO storage, special plant engineering as well as heat pumps. Assemblies, aggregates and container systems are prefabricated in the company's own workshop in Bremen, complemented by electrical and control engineering and control cabinet construction. A technical customer service with after-sales service is on call 24/7/365; this includes overhauls, retrofits, compressor technology, rental refrigeration systems (ThermoRent), remote maintenance and training. The Engelburg site (Canton of St. Gallen) serves the Swiss market.

Refrigerants and Processes
Ammonia (NH3)
Natural refrigerant for industrial refrigeration systems, e.g. ice sports facilities in the industrial sector.
Carbon dioxide (CO2)
Natural refrigerant for sustainable refrigeration systems in the industrial and commercial sectors.
Propane
Natural refrigerant for commercial refrigeration and environmentally friendly air conditioning technology.
R410A
Synthetic refrigerant, used among other things in an ice sports facility with 385 kW of refrigeration capacity.
