BRAZED HEAT EXCHANGER
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.
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
