What features take into account when choosing a compressor

Compressor technology is one of the most popular methods to cool systems down – compressor being the heart of a refrigerant machine. Main function of compressor is to rise the refrigerant’s pressure from evaporation temperature to condensation temperature. Being a mechanic machine, compressors require electricity to function and fluid to reduce the amount of friction.
Maintenance according to compressor type – know the technical facts of the machine
Compressors are divided to different groups according to their structure : hermetic, semi-hermetic and open compressors. When a compressor brakes down, it is not always profitable to mend it. When it comes to the most common compressor type – hermetic compressor – the easiest way to fix the malfunctioning compressor is to buy a new one from the same manufacturer. If the exact same compressor is no longer at the market, we are more than happy to help you to find a new one of similar kind. Searching of a new compressor is easy with the technical data sheets from the manufacturer. At Darment we have large product base including compressors and maintenance components – with the most known brands such as Danfoss, Tecumseh, Embraco, Emerson, Bitzer.
Hermetic compressors – take your pick from the large selection
In hermetic compressor, electric engine and compressor are inside the shell on top of transportation belt. Usage of belts minimizes the vibration of the components, which occurs due the movement. As the shell is closed by welding, hermetic compressor is hard to open without braking it. Hermetic compressors are applied in household refrigeration and freezers, super market refrigeration components, air conditioning components, water refrigeration machines and in heat pumps. Darment’s selection of hermetic compressors is especially wide.
Semi-hermetic compressors – maintain or purchase a new one
At Darment we also provide a selection of semi-hermetic compressors. In this model the engine and the compressor is inside a shell that can be opened, which makes the compressor easy to fix when a bug appears. Semi-hermetic compressors are mainly applied in super market refrigeration components but also in air conditioning products and water refrigeration systems.
Open compressors – buy spare parts for the maintenance
In open compressors the motive power is brought via the compressor’s shell via axis. The engine power is transferred to the open compressor via axis switch or belt. Open compressor is as easily fixed as the semi-hermetic compressor. Open compressors are usually applied in vehicle air conditioning systems, transportation refrigerant systems and to industrial applications. Grocery store refrigeration system is a sample of industrial application where open compressors are the most common compressor type. Open compressors are not in Darment’s selection at this time, but spare parts do belong in our product range. Ask for more!
