| APPLICATION
NOTES : Where values have been placed within brackets ( ), isentropic discharge temperature exceeds 120oC and water cooling for the cylinder jacket is essential. Capacity and Power Consumption are proportional to speed. Minimum permissible speed is 600 RPM. Please refer to us for Capacities and Power Consumption at other temperatures of evaporation and condensation and at other speeds. All figures are rounded off to + 2 %. Direction of Rotation : Anticlockwise when viewed from shaft end. |
