For high capacities the Kelvion GBS1000H is a familiar sight. If this unit is due for replacement, the UNEX PB88 is the 1:1 alternative: identical port-to-port dimensions (723 × 237 mm) and the same DN100 flange connections. The PB88 therefore connects seamlessly to the existing pipework and the existing flange joints. The PB88 is a brazed plate heat exchanger with AISI 316L stainless steel plates, copper-brazed. The series is available from 50 to 150 plates; you choose the version with the same number of plates as your current GBS1000H. A GBS1000H-90, for example, is replaced by the PB88H-90. Versions in this size are quickly available on request. Send us the type number of your unit — or look it up in the table above — and we will let you know the delivery time straight away.
