Ten Top Tips for Gasketed Plate Heat Exchangers
- Make sure the operating conditions, temperatures, and flow rates comply with design specifications.
- On start-up, vent the heat exchanger whilst slowly opening and closing the valves to avoid pressure surges and water hammer.
- Use up-stream filters and strainers to remove particulate fouling and to protect the heat exchanger.
- Check for changes in temperature or pressure and signs of external leaks on a daily basis.
- Keep the tightening bolts clean and well-lubricated.
- Have a performance check undertaken to avoid having to open the plate heat exchanger for inspection.
- Have a Cleaning-In-Place (CIP) service undertaken to avoid having to open the plate heat exchanger for cleaning.
- Always keep stand-by units clean and dry; if a heat exchanger is taken out of service flush with fresh water and drain completely.
- Protect heat exchangers from water splash and rain and avoid exposure to ultra violet rays and ozone typically generated from electrical sources.
- Only use genuine spare parts for guaranteed performance, reliability, and equipment life.
