  1. Features

    • 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 suit individual needs
    • Cross Contamination Eliminated
      • Each medium is individually gasketed
      • The space between gaskets is vented to the atmosphere
    • Easy to Inspect and Clean
      • 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 locate in gasket grooves positively
      • Lock-in feature available on most models
    • Highly Efficient Heat Transfer Performance
      • “U” values of 1,500 and higher 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 was 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
