MAXCHANGER® single- and multiple-pass designs fit virtually any application requirement. The MAXCHANGER all-welded plate heat exchanger offers higher performance, in less space, at a lower cost. The unique geometry of the patented MAXCHANGER’s variable interspaces produce extremely high “U” values. Channels formed between the specially dimpled, welded plates direct the two heat transfer media counter currently through alternate paths for maximum efficiency, immediate thermal response and a close temperature approach capability of less than 1°C (2°F).

The 1-mm (0.039-in.) thick dimpled heat exchanger plates are sandwiched between top and bottom plates specified to withstand the design pressure. Special spacers separate the plates, isolating the channels and establishing countercurrent flow. Four corner angles (or half-pipes) are welded to side plates, top and bottom plates and to the heat exchange plate points, forming inlet and outlet headers.

The corner angle fittings or corner half-pipe fittings, enable inlets and outlets—NPT or flanged—to be located in any number of configurations for maximum flexibility in tight spaces.

This exploded view of the welded MAXCHANGER® unit shows the large number of dimpled contact points that provide maximum pressure resistance and heat transfer.

MAXCHANGER® can achieve an extremely close temperature approach of less than 1°C (2°F).
