Brazed Plate Heat Exchanger - 20 Plates 4"x12" 1"MPT 240,000 Btu

WiseWater Brazed Plate Heat Exchanger has a lightweight and compact design that allows for easy installation and service. It is made of stainless steel 316L, brazed with 99.9% copper, and has 1" male fittings. When compared to other types,the advantage of this heat exchanger is that it features corrugated plates that produce a highly turbulent flow which allows for a true counter-current exchange. A counter-current flow is the most efficient way of exchanging heat between two fluids. Because of this, and due to the smaller size and reduced material content, Brazed Plate Heat Exchangers can be the most economical heat transfer choice. Depending on the application, the capacity ranges from 160,000 - 240,000 Btu/hr. This product has a 1 year warranty against manufacturer defects and is UL listed.

FAQ and Support
How to protect against freezing:
There are a few ways to help prevent freezing in your heat exchanger:
Using a freeze-protection thermostat and a flow switch in the spare connections (if available) to guarantee a constant water flow before, during, and after compressor operation;
use a filter mesh ~1mm; use antifreeze when the evaporating temperature is close to liquid side freezing. In addition to these freeze prevention tips, try to avoid operating the unit during pump downtimes. This product can be used with glycol (50%) for antifreeze purposes.
