An apparatus for regulating a compressor lubrication system includes an oil- flooded rotary gas compressor, a reservoir flow connected to the compressor, a best exchanger for cooling a lubricant, and a controller. A thermal muting valve regulates the temperature of the lubricant flowing to the compressor. A first temperature sensor measures a discharge temperature at a compressor outlet, and provides a signal corresponding to the discharge temperature to the controller. A second temperature sensor measures a lubricant temperature at a inlet be the compressor, and provides a signal corresponding to the lubricant temperature to the controller. A pressure sensor measures the pressure at the outlet of the compressor, and provides a corresponding pressure signal to the controller. A valve means continuously regulates the supply of lubricant to the compressor, the valve means being controlled by the controller in response to the temperature signal of the first temperature sensor sad the pressure signal. Operation of the thermal mixing valve is controlled by the controller, in response to the temperature signal of the second temperature sensor, to continuously regulate the temperature of the lubricant supplied to the compressor to minimize preheating of the low pressure gas.
