PSI Heat Exchangers (HEX-SM / HEX), also referred to as melt coolers, provide exceptional efficiency when cooling or heating viscous fluids.  The countercurrent flow, single-pass shell and tube design is available with helical static mixer inserts or with open tubes.

HEX-SM models add static mixing elements (alternating bow-tie twists) within the tubes to break up laminar flow that can inhibit heat transfer.  The turbulent movement fully exposes the process fluid to the cooling or heating surface achieving heat transfer rates three (3) to seven (7) times those of conventional open tube heat exchangers.  Offering a compact footprint and short residence times for space-critical applications, PSI’s HEX-SM heat exchangers are a smart solution for temperature control of prepolymers, polymers, and hot melt adhesives.

HEX open tube models have a larger footprint as compared to the HEX-SM models and are recommended for applications requiring low pressure drop and greater versatility.  Small diameter, stainless steel single pass, straight tubes have high surface-to-flow area for optimal heat transfer. The shell side features a single segmental baffle arrangement.

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