Our solutions for the safe storage of temperature-sensitive substances
Our solution for the storage of substances for pharma & medicine
Ultra-low temperature cold storage (ULT)
The KTI Ultra Low Temperature (ULT) storage system is a high quality, flexible, mobile and reliable storage solution for vaccine manufacturers, pharmaceutical companies, logistics and distribution centers and research institutes. In the temperature range from -30°C to -110°C.Â
With air as the refrigerant, the ultra-low temperature storage system is the most innovative product on the market for storing vaccines, pharmaceuticals and other temperature-sensitive substances.
Your innovative, safe solution for storage at the right temperature
This is how the KTI air chiller works in our ultra-low temperature warehouse
The air chiller operates in an open circuit. It draws in air that may contain ice crystals and dirt from inside the cold room, cleans it with two redundant filters, cools it and finally blows the air back into the cold room.
A distribution system evenly distributes the expanded cold air in the cold room. This results in an extremely homogeneous temperature distribution throughout the room.
The extremely low temperature at the intake reduces the dew point temperature by up to 20 K. This means that the products are stored in a particularly dry environment.


Air as a natural refrigerant - pure sustainability
Air as a natural refrigerant - pure sustainability!
The ULT mobile warehouse uses an innovative, efficient and sustainable air cycle refrigeration technology. The chiller is based on the Joule-Bryton process with air as the only refrigerant. With a maximum overpressure of 1 bar, this is an extremely safe and stable process.
At its core is an oil-free compressor-expander unit that compresses and expands on the same shaft for energy recovery.
The main advantage: air as a refrigerant is natural, always available and free of charge, non-toxic, Non combustible and harmless to humans and the environment!
Highest operational reliability through innovation
One of the most common causes of refrigeration system failure is compressor damage. The reasons include liquid refrigerant entering the compressor or insufficient lubrication due to lack of oil or poor oil quality. In addition, in cascade systems for low-temperature plants, several compressors have to operate simultaneously, which increases the probability of failure.
Advantage of the KTI technology: Our technology has no phase change, no oil and is wear-free with its air bearing. This guarantees the highest level of reliability.
