20+ employees
More than 20 specialists from the fields of refrigeration technology, control technology, pipeline construction and plant engineering plan and realise industrial refrigeration systems.
KSI Kältetechnik combines engineering, manufacturing and project handling in one continuous system and realises industrial refrigeration systems from planning through design and pipework to installation, filling, wiring and commissioning. This results in technically well-designed, operationally reliable and economically efficient systems.
In doing so, KSI Kältetechnik consistently relies on natural refrigerants. These systems remain permanently free of regulatory restrictions, ensure stable operating costs and offer high investment security. An interdisciplinary team of engineers, technicians and project planners guarantees a standard-compliant implementation as well as a design suited to industrial continuous loads.

Company Profile
More than 20 specialists from the fields of refrigeration technology, control technology, pipeline construction and plant engineering plan and realise industrial refrigeration systems.
We have been implementing refrigeration projects of various sizes for over 15 years. The scope of services ranges from planning and design to on-site installation.
For complex systems, KSI Kältetechnik works together with our specialised planning partner 2K Plan GmbH. There, system architectures, energy assessments and 3D planning models are created for seamless project coordination.
KSI Kältetechnik realises refrigeration systems for the automotive industry, food production, metalworking, medical technology, IT infrastructure, the plastics industry, as well as industrial end users with high demands on operational reliability and energy efficiency.
System planning and energy structures
KSI Kältetechnik plans and realises industrial refrigeration systems as integrated overall systems. All components are technically and energetically matched to one another, rather than being treated as individual solutions. This enables stable, efficient and expandable systems for industrial applications.
In addition to refrigeration technology, adjacent energy systems are also integrated. These include temperature control systems, large-scale heat pumps, heat recovery, brine systems and air conditioning. This allows energy flows to be specifically controlled and operating costs to be reduced.
Start your project nowStrategic direction
KSI Kältetechnik develops refrigeration systems with natural refrigerants as the technical basis for long-term stable industrial plants. These systems ensure regulatory independence, high supply reliability and predictable operating costs.
As one of the few specialists in Germany, KSI Kältetechnik plans systems that combine cooling, heat and energy in an overall system. This includes heat recovery, large-scale heat pumps and coupled energy systems that are technically scalable and designed for future requirements.
Natural refrigerants form the basis for this. They enable permanently safe operation, long-term availability and reduced environmental impact.
