PSI Heat Exchangers (HEX-SM), also referred to as melt coolers, provide exceptional efficiency when cooling or heating viscous fluids. The countercurrent flow, single-pass shell & tube mixer design features brazed helical static mixer inserts. Brazing optimizes thermal conductivity through the tubes into the mixers or vice-versa. Removable mixer elements are optionally available for applications requiring occasional cleaning, such as product changeovers.

The static mixer inserts (alternating bow-tie twists) eliminate the insulation and fouling layer that builds up along the inner wall in conventional open-tube designs. Flow within the mixer tubes provides consistent turbulent movement that fully distributes and exposes the process fluid to the cooling or heating surface. This results in heat transfer rates three (3) to seven (7) times those of conventional open-tube heat exchangers, in turn, yielding a compact footprint and short residence times for space-critical applications. These energy-efficient heat exchangers are a smart solution for temperature control of prepolymers, polymers, and hot melt adhesives.

HEX-SM heat exchangers are custom manufactured to individual process specifications.
