Service that’s bound to impress

After Sales & Service Header


As further proof of FUNKE’s commitment to the customer, we have an experienced customer service team who offer comprehensive services relating to heat exchanger repair and maintenance.

For plate heat exchangers, we offer services ranging from general inspections and thorough cleaning to re-gasketing of plate packs. It is essential to clean plate heat exchangers regularly, to ensure that heat exchange remains as energy efficient as possible, and to minimise the risk of malfunction. Proper cleaning entails removing all organic and inorganic contamination, and checking for leakages.

FUNKE experts can clean smaller exchangers on-site. With its many years of experience, our service team can properly clean plate heat exchangers in short order, for safe, energy-efficient operation.

Larger exchangers and plate packs are dismantled, taken to FUNKE for cleaning, then reinstalled. Re-gasketing of bolted plate heat exchangers is another service on offer, to ensure that the related production processes continue to run smoothly, and includes replacing worn gasket elements.

Customers can request general inspections of both plate and shell-and-tube heat exchangers, in which case the FUNKE team will arrive promptly in its modern, well-equipped vehicle, and will attend to the maintenance and repair of the equipment in expert fashion.

To minimise the risk of heat exchangers malfunctioning, FUNKE also offers its customers longer service contracts mandating regular inspections. Specific checks and regular cleaning can significantly extend the service life of heat exchangers, helping to avoid production downtime.
