Spindle Oil Coolers

Reliance Engineering Company offers Spindle Oil Coolers. These are used to reject the heat generated by the spindle bearings during high speed operations thereby increasing the life of the bearings and assisting in attaining accuracy. The spindle oil/coolant is drawn from the SS sump available in the cooler and circulated through the cooling circuits of the spindle. The unit utilises a brazed plate heat exchanger to transfer heat at a constant level and maintains the sump temperature uniformly. The differential temperature controller maintains the oil/coolant at a constant temperature with respect to the ambient temperature thus avoiding vast difference in temperature of the spindle and ambient to avoid water condensing on the spindle head during operations. The company has the following standard models to offer. Specifications: Models – SOC 10 – SOC 15 – SOC 20 – SOC 30 – SOC 45; capacity in watts/hour – 1000 – 1500 – 2200 – 3000 – 4500; power input in watts – 650 – 850 – 1250 – 1750 – 2250; source – both 230 V single phase 50 Hz and 440 V 3-phase 50 Hz versions; refrigerant – R-134a – R-22 – R-22 – R-22 – R-22; dimensions in mm (L x B x H) – 400 x 500 x 800 – 480 x 650 x 1150; and weight-dry in kilograms– 40 – 45 – 55 – 65 – 80.
