SWEP E5TH Brazed Plate Heat Exchanger – 40 Plate, 3/4" BSP (E5THx40)

SWEP E5THx40 Brazed Plate Heat Exchanger

The SWEP E5THx40 is part of the SWEP E5TH series of brazed plate heat exchangers, designed for efficient heat transfer between two separate water circuits while maintaining hydraulic separation.

Brazed plate heat exchangers use stacked stainless steel plates with copper brazing to maximise heat transfer surface area in a compact design. The E5TH series is commonly used in heating systems where space is limited but reliable heat transfer is required.

The E5THx40 is suitable for both heat pump systems and traditional boiler heating systems, making it a versatile option for residential and light commercial installations.

Temperature Difference (ΔT)
Typical heating systems operate with a temperature difference depending on the application:

• Heat pump systems: typically 5–10°C ΔT
• Boiler systems: typically 10–20°C ΔT

Typical Applications

• Boiler heating systems
• Heat pump installations
• Underfloor heating circuits
• Thermal store connections
• Hydraulic separation between heating circuits

Other Popular E5TH Plates

Installers often select from the following E5TH plates depending on system size:

• E5THx20
• E5THx30
• E5THx40
