Accu-Therm® Plate Heat Exchanger

Accu-Therm plate heat exchangers are designed to provide you worry-free, highly efficient heat transfer whether you are processing simple fluids, viscous solutions, or particulates. Accu-Therm plate heat exchangers are available in an extensive range of sizes, alloys, and frame configurations to meet your exact needs. 

Defining Features

  • Indoor
  • Accelerated Delivery
  • Flexible Requirements


  • Close Approach Temperatures
    • Approach temperatures of 2 to 3°F are possible because of the true counterflow and high heat transfer efficiency of the plates.
  • Compact and Lightweight
    • Requires 1/5 to 1/2 less floor space than other types of heat transfer equipment.
    • Lighter in total weight than other heat exchangers because of reduced liquid volume and the more efficient surface area for a given application.
  • Connections
    • Studded ports are standard and can be fully lined to protect against erosion and corrosion of the frame.
    • Lap-joint, weld-neck, ferrule, and victaulic connections are also available.
    • Connections can be mixed and matched to suite individual needs.
  • Cross Contamination Eliminated
    • Each medium is individually gasketed.
    • The space between gaskets is vented to atmosphere.
  • Easy to Inspect and Clean
    • Simply remove the compression bolts and slide away the moveable end frame to inspect 100% of the Accu-Therm heat transfer surface.
    • Easy and economical to clean-in-place (CIP).
  • Expandable
    • Adjust the unit’s thermal performance by adding or removing plates.
  • Extensive Selection
    • Heat transfer surface areas from 0.5 to 51 square feet.
    • Multiple embossed patterns.
    • Exclusive “free-flow” plate design.
  • Frame Assembly
    • Heavy-duty construction.
    • Optimum plate pack compression and leak prevention.
  • Gaskets
    • Designed to positively locate in gasket grooves.
    • Lock-in feature available on most models.
  • Highly Effecient Heat Transfer Performance
    • “U” values of 1,500 and greater are possible!
    • Accu-Therm plates promote high turbulence at low fluid velocities.
    • High turbulence results in very high heat transfer coefficients.
  • High Flow Rates
    • Flows up to 24,000 gpm.
    • Port diameters up to 20".
  • Inspection and Testing
    • Rigorous quality assurance inspections.
    • Each circuit independently tested at full design pressure.
    • ASME registration available.
  • Lower Cost
    • More economical than other types of heat exchangers due to the higher thermal efficiency and lower manufacturing costs.
  • Multiple Duties with a Single Unit
    • Heat or cool two or more fluids within the same unit by installing intermediate divider sections.
  • More Heat Transfer Surface
    • Up to 25,000 square feet (2,323 square meters) of heat transfer surface in a single exchanger.
  • Reduced Fouling
    • High turbulence, uniform fluid distribution, smooth plate surface, and high shear stresses reduce fouling.
  • Shrouds
    • Optional OSHA-approved plate pack shrouds are available in attractive and durable embossed aluminum or 2B stainless steel to protect personnel.
