Material & Thickness

The most common material for plates is 304 or 316 Stainless Steel and Titanium in a (.4mm)*, (.5mm) or (.6mm) thickness. Also available in SMO 254, Alloy C276, C22 and Nickel 200.

*Service is not available on (.4mm) plates. Since these plates are quite thin and damage easily, tightening tends to deform the plate channel not allowing the gaskets to seal properly which will cause the PHE to leak. When service is required on PHE’s with (.4mm) plates THS highly suggests upgrading to (.5mm) or higher.

Double Wall Plates

Double wall plates provide double the security against liquids intermixing in the event of a plate rupture. Consisting of two identical plates laser welded together, leaving a thin air gap between the plates acting as a safety zone in case either of the plates were to fail. In the case of failure, one of the two fluids would leak through the first plate preventing it from going any further due to the air gap and the second plate. The leak would be seen externally on the heat exchanger. This design offers maximum safety against cross contamination.

Typical applications include:

Transformer Oil Cooling – Water / Oil mixture can result in severe damage to transformer

Chemical Processes – Intermixing can cause contamination, explosions, chemical reactions, corrosion

Potable Water Heating – Distributing heat generated in a centralized location for residential and commercial heating requirements such as space heating and water heating, intermixing could scald, pollute tap water

Type (Standard)

Starter

A full gasket seals all the ports diverting the media directly into the ports and not across the plate.
Flow

(Channel)

Multiple plates with alternating gaskets compressed together to create a plate pack. Hot and cold media alternates through open channels transferring heat. The amount of flow plates in the heat exchanger are determined by the size of the heat transfer surface required.
Partition

Typically found in multi-pass configurations, made of solid carbon steel.
Transition

Added to the plate pack to prevent media from making contact with the partition or pressure plate.
End

The end plate is blank without port holes reversing the media back through the plate pack. Multiple pass plates have only two holes for redirecting the media.
