Level Recuperator

In 1992 Bart Veltkamp, founder of Level, designed and patented the ‘366’ shape heat exchanger. This heat exchanger is still the standard in the market, with more than a million units produced by his patents. 30 years of designing and producing cutting edge, highly effective heat exchangers have culminated in the next level heat exchanger. A complete rethink of the manufacturing process has resulted in the next level heat exchanger, made completely from polypropylene and produced without hotmelt. The next level heat exchanger is 100% recyclable, has an exact fit and has a fully customisable height up to 800 mm. Of course, no concessions were made on performance; the next level heat exchanger has the highest effectiveness available with a 50% lower pressure drop!
