Material

Selecting the wrong gasket can be a timely and costly mistake. Let our experienced THS sales team recommend the most durable and cost effective gasket material for your application by providing us with the pressure, temperature and process liquid details.

Buna (NBR/Nitrile), EPDM or Viton materials are the most common plate & frame heat exchanger gaskets depending on the operating application.

Food Grade

Standard Grade

Aggressive Chemical Compounds

Changes in Gaskets:

Time – Relaxes
Temperature – Deteriorates
Oxidizing Agents – Hardens
Swelling – Chemical Absorption

Gaskets Material Depends on:

Fluids Used
Temperature and Pressure

Standard Gasket Styles

Clip - will usually have rubber tabs that are visible from the outside of the heat exchanger

Glue – no tabs and in most cases the brown glue is visible under the gasket; typically used in high pressure or high temperature applications

Ball - used in HVAC or FDA applications to allow for easy removal in the field

WHEN SHOULD A PLATE & FRAME HEAT EXCHANGER BE SERVICED?

As a heat exchanger becomes fouled with dirt, debris or scale, often the modulating valve provides additional hot or cold liquid to help compensate for the loss of efficiency of the heat exchanger.

Over time the control valve will continue to open fully. Unfortunately, on the hottest or coldest days, even with the valve fully open the heat exchanger cannot meet the thermal transfer requirements and the situation becomes critical.

Monitoring just the operating temperature provides a false sense of security. Recording the difference in the outlet and inlet pressures provides a more accurate result of the amount of fouling.

Fouling equal to the thickness of a piece of paper represents a 20% loss of thermal efficiency. In addition, the energy cost for pumps increases since the pump must work harder to overcome the increased pressure resistance through the PHE

T.H. Industrial Solutions Inc. (THS) has been servicing industrial plate and frame heat exchangers as with shell and tube heat exchangers. Professionally solving process problems across Canada since 2009. THS head office is located in Pickering, Ontario with a 6,000 square foot service center in Hamilton, Ontario.

Today there are fewer qualified people in this industry that know the products and understand the applications. Utilizing hands on experience and knowledge that has been gained by our THS sales and service technicians for over the past 30 years, we will take the time to understand what you require and strive to provide a prompt, educated and accurate response at a competitive price.

Our Heat Exchanger Cleaning Services, along with heat exchanger gasket replacement systems, and knowledge of heat exchanger gasket materials make THS your Industrial Heat Exchanger Service Solution
