R brazed plate heat exchangers are intended for cooling or heating systems to work as evaporators or cooling medium condensers.
The HEXONIC R series is a brazed plate heat exchanger engineered for refrigerant-side duty in cooling and heating systems, where it works as an evaporator or a cooling medium condenser. Specially adjusted corrugation geometry in the heating plates ensures effective refrigerant evaporation or condensation, making the R series a proven solution for heat pumps and refrigerating units.
Designed for compact, high-performance HVAC-R equipment, the R series combines high heat exchange efficiency, solid compact construction, and compatibility with modern refrigerants. The range also features HEXONIC’s Refrigerant Distribution System (RDS), which improves droplet distribution and supports even evaporation across the full heat exchange surface, regardless of heating channel position relative to the inlet connection.
Key Features
- Effective refrigerant evaporation and condensation: The specially formed channels and adjusted corrugation pattern are designed to support efficient phase-change heat transfer in evaporator and condenser duty.
- Optimised for modern refrigerants:The R series is suitable for today’s refrigerants used in heat pumps and refrigeration systems.
- RDS refrigerant distribution system: THEXONIC’s RDS improves even refrigerant distribution in evaporator channels and helps reduce steam overheating fluctuations, supporting more effective use of the full plate area.
- High operating pressure capability: The R series allows operation with cooling medium pressures up to 45 bar.
- Compact, robust construction: The product offers a solid, compact design suitable for integration into heat pumps, refrigeration equipment, and other space-constrained systems.
- Resistance to frosting and high heat exchange coefficient: These are listed among the core product features on the live page.
- Material flexibility: The R series is offered with copper brazing or stainless LUNA brazing, depending on application requirements.
