Danish Technological Institute (DTI) is one of the world’s largest private institutes supplying technological services. DTI services include research on energy and climate issues as well as testing and consultancy services on heat pump and refrigeration technologies and the use of natural refrigerants. The centre for Refrigeration and Heat Pump Technology has special expertise in R744, R718, and R717 projects.

Many DTI activities revolve around the use of natural refrigerants, including CO₂, (R744) and the laboratory facilities comprise an XXL climate chamber with a transcritical booster CO₂ plant which enables testing of almost all kinds of systems and components for refrigeration and heat pump systems, such as heat exchangers (e.g. plate heat exchangers, shell-and-tube or finned tube heat exchangers), evaporators, gascoolers and oil separators as well as control systems. The transcritical CO₂ plant has a cooling capacity of 150 kW and a frost capacity of 20 kW.

Other facilities enable accredited testing of all types of commercial refrigerated display and storage cabinets, and the testing facilities are equipped to test remote CO₂ cabinets with an evaporation temperature down to -35°C.

DTI activities also include conferences and training courses providing the latest know-how on current topics, e.g. the training course: Refrigeration Plants with CO₂ – theory and hands-on. For more information and registration: www.teknologisk.dk/k27561
