ULTRAMAX® Welded Heat Exchanger

The ULTRAMAX® heat exchanger is designed for use with liquids, gases or two-phase mixtures at extreme temperatures to 343°C (650°F) and pressures up to 45 barg (650 psig) for standard range units. Extended range units are available for higher temperature and pressure applications.

ULTRAMAX® significantly high “U” values result from the unique turbulence created by the unit’s corrugated plates. The resulting velocity profile eliminates stagnant areas and promotes maximum heat transfer. ULTRAMAX® welded plate heat exchangers provide true countercurrent flow, unlike some competition cross flow units. Countercurrent flow offers full LMTD and allows for 1°C (2°F) temperature approaches. Induced turbulence scours the heat transfer surface during operation, thereby reducing fouling. This turbulence also aids the effectiveness of CIP procedures.

Working in much the same way as a conventional, gasketed plate & frame heat exchanger, the ULTRAMAX® embossed metal plates are arranged alternately into cassettes and welded to form channels for hot and cold media. The plate pack is enclosed in a welded core with nozzles and installed in a frame to provide pressure integrity.

The majority of the heat transfer plate welding is performed via a cost effective and reliable seam weld. The baffle clips eliminate continuous welding between the cassettes.
