All-welded heat exchangers

Tranter PHE has launched a high volume Ultramax all-welded plate heat exchanger for extreme temperature and pressure applications, and corrosive applications unsuitable for traditional gasketed exchangers.

The large capacity model is suitable for liquids, oil and gases or two-phase mixtures at temperatures up to 343°C and pressures up to 70barg for standard range units, with extended temperature and pressure range versions also available to order.

The exchangers feature counter-current flows on adjacent plates, offering full LMTD (log mean temperature difference) and allowing closer temperature approaches between product and heating/cooling streams. Large capacity or multi-pass configurations incorporate up to five cores within a single frame.

The range offers eight different plate lengths, including the largest plate size in its class, with an area of 0.989m2. Maximum surface cooling area of the largest unit is 300m2 with flow rates in excess of 1500m3/h.
