BRAZED HEAT EXCHANGER

Oil Cooling Applications

Operating Details

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.

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:
50°C to 437°F (10° to 225°C)(freezing point and boiling point must be taken into consideration!)

 

Pressure:

  • max. 49 psi (3 bar) (static) up to 257°F (125°C)
  • max. 435 psi (30 bar) (static) up to 437°F (225°C)
  • test pressure: 650 psi

 

Corrosion:
The following limits refer to a pH value of 7

  • free chlorine, CL2 < 0.5 ppm
  • chloride ions CL < 700 ppm at 20°C, < 200 ppm at 50°C

 

Other limits:

  • 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:
phophate, nitrate, nitrite, iron, manganese, sodium and potassium
