About Us

The UK's First and Only National Plate Heat Exchanger Manufacturer

Backed by 20 years of engineering experience, MeSource is establishing Britain's domestic manufacturing capability for copper brazed plate heat exchangers.

Every unit is vacuum-furnace brazed and undergoes helium leak testing and hydrostatic pressure testing before dispatch. Our quality management system is being developed in accordance with internationally recognised standards. ISO 9001 certification in progress.

  • ✓ Designed and manufactured in the United Kingdom
  • ✓ Pressure equipment conformity requirements addressed
  • ✓ 100% leak tested before every dispatch

Where It's Used

Where the MeSource Heat Exchanger Fits in Your System

Our compact brazed plate heat exchanger sits at the centre of the hydraulic separator and buffer tank, transferring heat between the energy sources — boiler, heat pump and chiller — and the building's hot water, ambient water and chilled water circuits.

Product Features

Why Copper Brazed Plate Heat Exchangers?

A gasket-free, compact construction with a high-turbulence flow design, outperforming conventional heat exchangers on every front.

High Thermal Efficiency

A corrugated plate pattern creates turbulent flow, delivering high heat transfer performance from a compact surface area.

Compact & Lightweight

Significantly smaller and lighter than many conventional heat exchanger designs, easy to install even in the tightest plant rooms.

High Pressure Resistance

Vacuum-furnace copper brazing creates a gasket-free construction rated for working pressures up to 45 bar.

Long Service Life

AISI 316L stainless steel plates provide excellent corrosion resistance and long-term durability.

Sustainable by Design

Low internal volume and efficient heat transfer can help reduce system energy consumption, making the technology well suited to heat pump applications.

Our Mission

We supply the compact, efficient heart of the heat pump.
