Hermetic Piston Compressor
A piston compressor, also known as a reciprocating compressor, is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure. A hermetic design makes the compressor safe to operate and function smoothly. Made from quality materials and electronic parts, this hermetic reciprocating compressor runs reliably and efficiently, and it has a long service life, is relatively quiet, and saves energy. Several types of thisgas compressor are available for customers' differing needs, which are used in manufacturing air conditioners, refrigerators, cooling machines, and dehumidifiers.
