SWEP AsyMatrix^TM

SWEP was the first company on the market to offer asymmetric brazed plate heat exchangers. SWEP’s innovative asymmetrical channel configuration combines maximum heat transfer on the refrigerant side with minimum pressure drop on the secondary side. This asymmetric plate design technology delivers improved thermal performance and higher efficiency than conventional heat exchangers, with a smaller footprint and lower energy consumption.

The benefits of SWEP AsyMatrix technology include:

Lower energy consumption
Lower total cost of ownership
Optimizing system efficiency and energy usage of the pump
Increased system-design flexibility
Minimal system footprint
Enhanced safety due to low refrigerant charge
Reduced carbon emissions, based on optimized use of materials and refrigerant

Symmetric plate pattern

The self-supporting plate geometry of a brazed plate heat exchanger (BPHE) delivers outstanding performance with only a fraction of the weight, footprint, and internal volume of a shell and tube. However, the plate design of a symmetric BPHE is always a compromise, where thermal performance is balanced against fluid pressure drop. Higher heat transfer results in excessive pressure drop, reducing the system’s performance.

SWEP AsyMatrix plate pattern

The asymmetric plate pattern of a SWEP AsyMatrix BPHE makes it possible to optimize the channel geometry according to the application area. SWEP AsyMatrix BPHEs combining excellent heat transfer with low pressure drop and reduced refrigerant charge. This improves the sustainability and efficiency of the system while also improving thermal and hydraulic performance.

How does it work?

The same mass flows through an asymmetric BPHE as through a symmetrical one. However, the asymmetrical patterns on the plates make it possible to achieve optimal pressure and heat transfer on both sides, conserving energy.

The SWEP AsyMatrix advantages in chillers

To achieve greater cooling capacity, fluid flows in chillers are high. In traditional heat exchangers, a high fluid flow increases the pressure drop, which means that more energy is needed for pumping, reducing the system’s overall efficiency. SWEP AsyMatrix technology reduces the hold-up volume of the inner circuit by up to 30%, while also maintaining both the pressure on the secondary side and the flow rate, for exceptional heat transfer and an improved COP.

SWEP AsyMatrix for boilers

In addition to being the first company on the market to offer asymmetric heat exchangers, SWEP was also the first company on the market to launch heat exchangers specially designed for the boiler industry—the SWEP E-range. We work continuously to improve our technology, launching our most recent asymmetric plate design concept in 2023.

SWEP AsyMatrix offers a genuinely asymmetric solution for boiler applications, with two thermally different sides that deliver

Improved heat transfer on the tap water side
Lower pressure drop on the central heating side
Fewer plates
Smaller footprint than shell and tube
Smaller, lighter brazed plate heat exchangers require less pumping capacity in central heating circuits

SWEP AsyMatrix offers a genuinely asymmetric solution for boiler applications, with two thermally different sides.

The SWEP AsyMatrix range

The SWEP FI22AS, SWEP PIT5AS, and SWEP FI190 are a few of our models equipped with our patented SWEP AsyMatrix technology. They function as asymmetric evaporators that combine low water pressure drop with high performance in chiller and heat pump applications. They deliver full performance at both full and half load.
