Product Variants
Our brazed plate heat exchangers are available in different circuit configurations and operating variants to match specific system requirements. From compact single-circuit units to dual-circuit and liquid suction gas designs, the portfolio enables precise adaptation to refrigerant circuits, pressure requirements, installation conditions and connection layouts.
Single Circuit models are used as evaporators or condensers and are available in several model sizes. The catalogue defines operating variants such as evaporator/condenser, evaporator with distributor, high-pressure version and high-pressure version with distributor.
Best for:
Refrigeration systems, air conditioning units, heat pumps and compact thermal systems with one refrigerant circuit.
Models include: S06, S07, S09, S12 - S12M, S16, S22, S62, S82 - S82M, S85, S87, S93, S101, S182 - S182M, S187, S202 - S202M, S404 - S404M, S606 - S606M, S608 and S727
Dual Circuit brazed plate heat exchangers support applications with two separate refrigerant circuits and one secondary fluid circuit. This configuration is suitable for systems that require greater flexibility, redundancy or divided refrigerant flow within one compact heat exchanger design.
Best for:
Chillers, larger HVAC systems and applications requiring two refrigerant circuits in one heat exchanger.
Liquid Suction Gas variants are designed for dedicated refrigerant-side heat exchange applications. They support compact integration into refrigeration systems and are available as specific LSG models for suitable system layouts.
Best for:
Refrigeration applications requiring liquid suction gas heat exchange in a compact brazed plate design.
High Pressure variants extend the operating range of selected brazed plate heat exchangers for systems with increased pressure requirements. Depending on the configuration, they are also available with distributor functionality, enabling compact and reliable integration into demanding refrigeration and air conditioning applications.
Best for:
Compact refrigeration and air conditioning systems with increased pressure requirements.
