Brazed Plate Heat Exchangers

Variant L 

Designed for heating and cooling installations, the L series offers high thermal performance with minimal operating costs. The brazing process ensures a permanent and airtight connection of plates, optimising performance and reliability. 

Variant R 

Optimised for cooling systems, the R series is used as an evaporator or condenser in heat pumps and refrigeration units. Its specialised refrigerant distribution system (RDS) ensures even evaporation and effective heat transfer. 

Variant SafePLATE 

Equipped with a double-wall system, SafePLATE heat exchangers prevent fluid mixing and provide early leak detection. They are ideal for applications requiring the highest safety standards. 

Variant Luna 

Constructed entirely from stainless materials, Luna series exchangers ensure high hygiene levels, making them ideal for systems with aggressive media, demineralised water, and sanitary installations. 

Variant AS 

Designed specifically for heating applications, AS asymmetric exchangers maximise heat transfer efficiency while minimising pressure drops. They are compact and allow for the use of lower power pumps. 

Variant L Ultra 

The L Ultra series is an eco-friendly solution optimised for CO₂ applications. Its high-pressure resistance and robust design make it ideal for modern cooling and heating systems.

Evaporators 

A two-phase refrigerant enters the bottom welded connection and evaporates as it moves through the heat exchanger, achieving the required overheating level. Water or glycol flows in a counter-current direction to maximise heat transfer. 

Condensers 

Hot refrigerant vapours enter the top welded connection and condense as they move through the heat exchanger, ensuring optimal subcooling. Water or glycol flows in the opposite direction for maximum efficiency. 

Heating & Cooling 

In HVAC and industrial systems, these heat exchangers effectively transfer thermal energy between media, ensuring stable operation and energy efficiency. 

Leak Detection & Safety 

SafePLATE’s double-wall system prevents fluid mixing by directing leaks outside the exchanger for quick identification and maintenance. 

With a wide range of variants and configurations, Brazed Plate Heat Exchangers provide reliable and efficient solutions for various heating and cooling applications.
