Design Center
The Natural Fluids Refrigeration Center (NFRC) is a collaboration between Isotherm and GIK Institute of Engineering Sciences and Technology.
Our purpose is to provide refrigeration solutions on a global scale. And we will accomplish this by providing the industry with continuing improvement in refrigeration processes.
The Center offers world-class research and analytical services to industry, academia, private, and government organizations.
The NFRC is one of the unique research centers that has been actively conducting research on thermal-hydraulic characteristics of high-efficiency heat exchangers using natural refrigerants.
The primary goal of the Center is to work on new and innovative techniques related to natural refrigerants and their effective use in refrigeration systems.

The Center has a team of highly qualified researchers and well-trained technical staff with advanced equipment. It collaborates with universities, institutes, and companies around the world that are interested in the core subject.
THE NFRC TEAM
Our mission is to conduct applied and fundamental research, provide consultancy and analytical services in Process Heat Transfer, Refrigeration, and Air Conditioning.

THE NFRC FACILITY
The Center is an experimental facility for detailed analysis of problems and challenges, and industry innovation.
- Modular design provides operational flexibility and control of experiemental parameters
- Designed so that condensation and evaporation heat transfer experiments are carried with minor changes in the set up
- A concentration on environmental issues
- The Center coordinates with different International Institutes and technical societies with common goals
- NFRC provides researchers, graduate students and engineers from industry and academia with the education and training they need to enjoy long and productive careers.
- Several types of experiments can be easily conducted for different refrigerants on different types of heat exchangers in single- and two-phase applications
- NFRC serves as a research and development hub covering all aspects of refrigeration technology (such as compressors, heat exchangers, controls, piping, novel materials, and metallurgy)
- The Center has developed high-quality experimental facilities to acquaint trainees with hands-on training
- We offer short technical courses for professional engineers working in today’s multi-faceted industry
