SM Heat Exchanger

What is SM Heat Exchangers?

Samhwa specializes in building SM (Static Mixing) Heat Exchangers which incorporate tubes of static mixing elements are especially suited for heating and cooling highly viscous fluids.

The mixing elements of SM Heat Exchanger continuously create a new Interface between the product and tube wall, thereby producing a uniform heat history in the product. This arrangement produces a heat transfer rate that is three to seven times that of conventional heat exchangers. These heat exchangers are very compact, producing a short residence time.


  • Polymer Cooler & Heater
  • Devolatilization Preheater & Feed Heater
  • Maintaining constant hot oil temperature in recirculation loops
  • Cooling hot melt adhesive products immediately before packaging
  • Heating viscous food product such as taffy, glucose products, corn starch
  • Healing proprietary sealants in production of self-sealing automobile tires
  • Cooling precursors used in carbon fiber production
  • Cooling polystyrene foam in extrusion processes

Standard Specification
SM Heat exchangers are custom designed for each application.

  • Material : Carbon Steel, Stainless Steel, Hastelloy, Inconel, etc.
  • Pressure : Exceeding 350 bar (5,705 psi)
  • Viscosities : Exceeding 20,000 Pas (20,000,000 cp)
  • Certifications : ASME, DIN, Chinese Safety Quality License, Others

Benefits / Advantages

  • Increased heat transfer coefficients three to seven times that of traditional open tube designs
  • Low pressure drop against high viscosity materials
  • Short and uniform residence time
  • Smooth shape and edge sealing of mixer elements allows no dead spaces for product
  • Can be used for materials with low to high viscosities
  • No moving parts, therefore no maintenance
  • Can process highly corrosive materials upon various options of materials to be chosen
  • Uniform temperature – no hot spots
