Permutadores de calor de placas HYDAC Hex S400-722 xxx

GENERAL

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

Plates and connections are manufactured from stainless steel to 1.4401 (AISI 316), vacuumbrazed with copper. The plates have smoothed edges and the end plate is provided with edge protection. The special moulding 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. The turbulent flow of the medium also has a selfcleaning action: fluids passing through the narrow channels induce highly turbulent flow at the walls. This results in a scrubbing action reducing contamination on the surfaces.

APPLICATIONS

Cooling circuits in reverse flow using water, coolants, HFC operating fluids or oil.
Typical applications are:

  • Machine tools
  • Presses
  • Plastic injection moulding machines
  • Engines
  • Test rigs

Generators

OPERATING DETAILS

Medium:

  • Water glycol (coolants)
  • HFC operating fluids
  • Water
  • Oil

Contamination:

  • 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.
  • Temperature range: up to 200 °C (freezing point and boiling point must be taken into consideration!)
  • Pressure: max. 30 bar Test pressure: 45 bar Nickel-brazed designs are available with an operating pressure up to 10 bar.
  • Water quality: The following ions are not corrosive under normal conditions: phosphate, nitrate, nitrite, iron, manganese, sodium and potassium The following limits refer to copperbrazed plate heat exchangers and a water temperature of max. 60 °C.
