1. The role of Sullair cooling fan in the dryer
The Sullair cooling fan is used to cool the circulating compressor oil to take away the heat generated during the compression process and the radiant heat in the carport. The main function of the Sullair cooling fan (fan) is to provide a cooling air source for the fan cooler. The flowing room temperature air passing through the heat exchange surface of the heat exchanger will take away the heat in the high temperature oil or high temperature gas, effectively reducing the temperature of Sullair dryer oil and compressed gas.
The Sullair cooling fan can be driven by a motor or a diesel engine. Sullair cooling fans are divided into axial fans and centrifugal fans according to their different structures; Sullair cooling fans are divided into suction and exhaust types according to the angle of the fan blades. Sullair dryers can be manually reversed in cold weather in high-cold areas. The suction fan will increase the temperature in the chassis, effectively preventing malfunctions such as icing of the control pipeline, and ensuring the normal operation of the internal control components of the machine.
