Description
WiseWater Brazed Plate Heat Exchanger features a lightweight and compact design for easy installation and maintenance.
It is constructed with 316L stainless steel plates and brazed with 99.9% copper, equipped with 1" MPT male threaded connections.
Compared to traditional heat exchangers, this unit uses corrugated plate technology, generating highly turbulent flow to achieve a true counter-current heat exchange, which significantly improves thermal efficiency.
Its compact structure and reduced material usage make it a cost-effective heat transfer solution for a wide range of heating applications.

Freeze Protection Guidelines
To prevent freezing and ensure safe operation:
- Use freeze-protection thermostat and flow switch (if applicable)
- Maintain continuous water flow before, during, and after operation
- Use ~1mm filter mesh
- Use antifreeze (up to 50% glycol) when required
- Avoid operating during pump downtime
Welding Instructions
- Recommended welding method: TIG or MIG
- Use damp cloth around connections to prevent overheating
- Apply small nitrogen flow to prevent internal oxidation
