Hellmich GmbH & Co. KG

The environmental engineering ­specialist Hellmich is focussing on heat exchangers (read: heat recovery) at this year‘s Ceramitec.

Much of the overall cost in the production of ceramics goes for energy, and that cost pool is bound to expand in the years to come.

One way to keep a lid on it, though, is to recover thermal energy from kiln exhaust gases. With that in mind, Hellmich has come up with a flue gas/air heat exchanger made of rectangular pipes instead of the usual round tube bundles, so Hellmich‘s heat exchangers can be cleaned by means of a simple, robust, low-maintenance system that ensures consistently good heat transfer. In addition, part of the recovered warm air is added to the cooling air, hence ­effectively preventing unwanted condensation.
