Brazed plate heat exchanger
0.09 - 8 kW | M series COSTANTE SESINO

WATER-OIL HEAT EXCHANGERS
WITH BRAZED PLATES
TECHNICAL CHARACTERISTIC
Maximum working pressure 30 bar. Working temperature must be between -160° and +225°C. The maximum temperature difference between the fluids is 100°C For all exchangers the graph relating to thermal yield, as a function of the oil rate, shows the heat value in kw or in kcal/h that the exchanger is able to disperse for each degree of difference between the inlet temperatures of water and oil. The yield diagrams have been calculated with a ratio between the oil and the water flow rates of 2/1; for higher ratios, the lower water consumption, it is necessary to multiply the factors obtained from the graph by the following Ka coefficients
Ratio 2/1 3/1 4/1 5/1 6/1 7/1 8/1 9/1 10/1
Ka 1 0,92 0,85 0,75 0,7 0,65 0,6 0,55 0,5
The yield diagrams and the pressure losses are valid for oil ISO VG46; for different oil viscosity it is necessary to multiply the value obtained from the graph for the Kc coefficients, by the yield diagrams, and Kp by the pressure loss diagrams.
