- EN - info@finicompressors.it 40069 Zola Predosa (BO) - ITALY 5.5 REFRIGERATING COMPRESSOR The refrigerating compressor is the pump in the system, gas coming from the evaporator (low pressure side) is compressed up to the condensation pressure (high pressure side). The compressors utilized are manufactured by leading manufacturers and are designed for applications where high compression ratios and wide temperature changes are present.
- EN - info@finicompressors.it 40069 Zola Predosa (BO) - ITALY 5.9 FILTER DRIER Traces of humidity and slag which could accumulate inside the chilling plant, or smudge which could occur after a long use of the dryer, could limit the lubrication of the compressor and clog the capillary tube. The function of the Filter Drier, located before the capillary tubing, is to stop the impurities, so avoiding their circulation within the system.
- EN - info@finicompressors.it 40069 Zola Predosa (BO) - ITALY 5.13 REFRIGERANT PRESSURE SWITCHES P – P – P As operation safety and protection of the dryer a series of pressure switches are installed in the gas circuit. PB : Low-pressure controller device on the suction side (carter) of the compressor, is enabled only if the pressure drops below the pre-set value.

This drain consists of a condensate accumulator where a capacitive sensor continuously checks the level of the liquid: as soon as the accumulator is filled, the sensor passes a signal to the electronic control and a diaphragm solenoid valve will open to discharge the condensate.
