New applications demand ever-increasing performance. In response to the call, GEA PHE Systems remains in the forefront of technological develop- ment. Because conventionally sealed plate heat exchangers quickly reach their limits with critical media, GEA PHE Systems provides the answer – the new Laser-Welded Cassettes (LWC) plate heat exchanger. Agressive media ty- pes can now ow safely. The LWC range is based on the NT plate technology and bene ts from the very latest computational design and manufacturing techniques.
