During your PHE service our team will thoroughly examine your PHEs, making sure that any sealing problems or deformities are corrected. Our servicing centre is specifically designed to take worn plates, test their integrity and refurbish them ready to use again.  Unison only uses top of the range spares, and we ensure that we use the best quality gaskets and glues. 

Unison's Service team can dismantle the pack on location, perform the service and return to fit it when complete or alternatively plate packs can be delivered directly to our Limerick based service centre. 

Unison can also provide full on-site servicing which includes changing plate packs out, regasketing, Inspection and Reporting on PHE's. 

For any model or brand Regardless of where or when they were made, Unison is well a one stop shop for servicing, refurbishment and repair.

Risks of attempting to service your PHE's yourself

Reconditioning with the wrong tools or parts can seriously damage your PHEs. Scraping and chemicals can harm the plates, and improper sealing can lead to leakage.  We would highly recommend that you use a service team that are experienced in Heat Exchanger Servicing. Attempting reconditioning yourself or using a less qualified supplier may save time and expense up front, but without the right experience, smaller defects can be missed which can lead to major problems in the future.

Some plate failures which can occur due to incorrect servicing or refurbishment include: Plates Being Destroyed, Leakage, Production Losses, Safety Risks, Damaged plates, gaskets being damaged or falling off.

The Risk isn't worth the potential damage, make sure you use a trusted, experienced supplier like Unison!
