HXP-135 Compact Plate Heat Exchanger

Part No. HXP-135 This product is archived and displayed for information only. It is no longer available for purchase. Released: 23 October 2009

Plate heat exchangers provide highly efficient heat transfer between two liquids without allowing them to mix. They are ideal for managing coolant pressure differences, and for isolating sensitive equipment from potentially damaging liquids. Koolance plate heat exchangers are among the most compact and cost effective available.

The HXP-135 is a proprietary Koolance design, and possibly the smallest heat exchanger of its kind. It is made of copper-brazed stainless steel and plated externally in nickel. A detachable heavy steel mounting bracket and screws are included. G 1/4 BSPP threading.

Liquid Coolants

Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth. Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use silver with nickel in the same system.
