Working principles
The heating surface consists of thin corrugated metal plates stacked on top of each other. Channels are formed between
the plates and corner ports are arranged so that the two media flow through alternate channels, always in counter-current
flow. The media are kept in the unit by a brazed seal around the edge of the plates. The contact points of the plates are also
brazed to withstand the pressure of the media handled.
Standard design
The plate pack is covered by cover plates. Connections are located in the front or rear cover plate. The channel plates are
corrugated to improve heat transfer efficiency and to make them rigid.
Standard materials
Cover plates: Stainless steel AISI 316
Connections: Stainless steel AISI 316
Plates: Stainless steel AISI 316
Brazing material: Copper
Particulars required for quotation

Hydraulic oil cooler Description
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 AISI 316, vacuum brazed with cooper. 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.
Operating Details
Medium:
Water glycol
HFC operating fluids
Water
Oil
Contamination
The quantity of particles in suspension should be less than 10 mg/l, particle size <0.6mm
Thread like particles cause a rapid rise in pressure drops.
Temperature range:
10C to 225C (freezing point and boiling point must be taken into consideration)
Pressure:
Max 45 bar up to 225C, testing pressure 60 bar.
Corrosion
The following limits refer to a pH value of 7
Free chlorine. CL2<0.5ppm
Chloride ions CL
<700 ppm at 20C
<200 ppm at 50C
Other limits
PH7-10
SULPHATE so4 2-<100 ppm
[HCO3]/[SO4 2-]>1
Ammonia, NH3< 10 ppm
