Heat exchangers are used to exchange heat between two fluids. Plate heat exchangers are high performance components and provide a high level of efficiency combined with compact dimensions and low weight. Their efficiency reduces the amount of cooling water required for heat transfer which results in low operating costs.

Features N/A Plates and connections are manufactured from stainless steel to AISI 316, 1.4401, vacuum-brazed with copper. The special molding of the plates produces the turbulent flow necessary for effective heat transfer and provides the plate heat exchanger with a high level of mechanical strength. Nickel brazed option available.
Contamination N/A The quantity of particles in suspension should be less than 10 mg/l.
Particle size < 0.6 mm (spherical).
Thread-like particles cause a rapid rise in pressure drops.
Corrosion N/A The following limits refer to a pH value of 7
  • Free chlorine, CL2 < 0.5 ppm
  • Chloride ions CL
      • < 700 ppm at 20 ºC
      < 200 ppm at 50 ºC
Other Limits N/A
  • ph 7 - 10
  • Sulphate SO4 2- <100 ppm
  • [H CO3 -] / [SO4 2- ] >1
  • Ammonia, NH3 <10 ppm
  • Free CO < 10 ppm
The following ions are not corrosive under normal conditions:
phosphate, nitrate, nitrite, iron, manganese, sodium and potassium
Applications N/A AIB cooler element bypass option for high viscosity applications.
Pressure Drop Across Heat Exchanger N/A This is based on an ISO VG45 oil at 130ºF and shows the pump flows with the 1,800 RPM motors. If other grades of oil are to be used, consult the sizing software. When using the 72 psi clogging indicator the pressure drop should not exceed 15 psi max across the heat exchanger. When using the 29 psi clogging indicator the pressure drop should not exceed 30 psi max across the heat exchanger.
Additional Information N/A The cooling capacity is also dependent on the viscosity class. At a lower viscosity class the cooling capacity increases, at a higher viscosity class it decreases. In order to make an accurate calculation, the following details are required:
  • type of oil
  • permissible tank temperature
  • required outlet temperature of the oil or necessary cooling capacity
  • inlet temperature of the water and maximum water quantity.
Selection Program

The cooler selection program calculates the correct heat exchanger in the case of non-standard operating data.
Please contact our technical sales department.
Note N/A Mounting brackets must be ordered separately.

Pipes must be connected so that connections are stress free. Linear expansion and vibrations from the pipes to the heat exchanger must be avoided.

For mounting heat exchangers with 60 plates and above, two clamps are recommended.
