Re/Gent B.V. is a Test and R&D centre specialized in refrigeration, air conditioning and heat pumps, with emphasis on green innovations, energy efficiency and alternative refrigerants. Re/Gent B.V. has its own laboratory, available for practical investigations on domestic and commercial appliances and components. A part of the activities of Re/Gent B.V. consists of testing and verification of various requirements of domestic and commercial products or equipment. In this respect it is relevant that Re/Gent B.V. is ISO/IEC 17025 accredited for testing the energy consumption and performance of household refrigerators, commercially used plug in coolers or freezers and refrigeration equipment. Test rigs and test facilities are produced in-house and are also delivered to customers upon request. Re/Gent B.V. has built its own software tools for actively developing new innovative refrigeration systems. Rankine and Peltier based refrigeration systems are regularly used, but Re/Gent B.V. is also familiar with “not in kind technologies” such as the Stirling cycle, evaporative cooling, air cycle or magnetic cooling. Consultancy is given to customers, upon request completed with theoretical studies and literature surveys. The design and development of computer simulation software completes the list of activities.
