About Us
Cool Partners is a small consulting company with a little twist – Cool Partners bring more experience and more expertise with it than most larger companies will be able to offer, yet you’ll still benefit from a personal one to one service.
Per Skærbæk Nielsen has more than 35 years in the industry, and has been working intensively with compressors, valves, troubleshooting, system development and design through his hole career. All the knowledge gained from this is used in the consulting work and summed up in technical seminars for advanced education and training of refrigeration technicians in the industrial refrigeration area.
Cool Partners cater to all areas of the industry, including manufacturers, refrigeration contractors and end users, and more importantly Cool Partners build close relationships with all our customers to become their preferred partners throughout the growth of their companies.
The focus is on the industrial and large commercial refrigeration segment. The primary focus areas are energy optimization and energy audits, trouble shooting, review and optimization of existing systems and new builds, as well as design and development of advanced processes and equipment for the refrigeration segment. Solutions already developed address well known problems in refrigeration systems with a new approach, with highly efficient and simple operation resulting in savings in service and operating costs.
- CO2 cascade systems – with or without hot gas defrosting
- Industrial transcritical CO2 systems
- Oil return with built-in purification
- Oil analysis – system diagnostics
- Thermodynamic calculation and design of systems, heat exchangers, vessels etc
- Design of process equipment
