screw compressor vs reciprocating compressor

screw compressor vs reciprocating compressor

Reciprocating compressors are best for applications that require air for shorter durations of time and have breaks between uses. This unloaded power consumption typically consumes about 35% of the compressor full load value. The vast majority of Sabroe compressor models (both reciprocating and screw types) are available with variable-speed drive (VSD) to provide stepless control of your compressor capacity. However, repair costs in the event they do break could be much higher than with some other compressors. The valve of a Reciprocating Compressor is considered to be the heart of the equipment. The short answer it that each compressor type has its particular advantages, depending on the required operating conditions. “A&W is the finest compressor company I’ve ever had the pleasure of dealing with. They works well in high temperature applications, delivering energy savings. The age-old debate is explored by Russell Hattingh, engineering manager, Johnson Controls Systems and Service, South Africa. For heavy-duty, high horsepower needs, a rotary screw could be your best bet. Relevant criteria, such as required capacity, operating conditions, part load, energy consumption, temperature levels, refrigerant, ease of maintenance, investment and available space should be taken into consideration. Rotary compressors generally require simple filter and lubricant upkeep. Screw Compressor Scroll Compressor However, in India, most air conditioners unit integrates either Rotary Compressor or Reciprocating Compressor so, it is quite important for you to understand the difference between these two types of compressors. By the nature of its design, the rotary compressor generates less vibration . ”, “A&W is the finest compressor company I’ve ever had the pleasure of dealing with. Small reciprocating and portable compressors are ideal for small job sites, whilst stationary rotary screw compressors provide much higher volumes of compressed air. A reciprocating air compressor, or piston compressor, is a low horsepower compressor for applications where reliability is vital. However, after the same number of operating hours the energy savings with a recips will typically be three to five times larger than the higher maintenance costs. On typical reciprocating compressors, used on some OEM equipment, the compressor is driven by a stand-alone diesel or gas engine, or is hydraulic-driven, and operates continuously while the engine is running. There is no single answer to this question of choosing between recips and screws — it depends on the application, operating conditions and attitudes. The oil-injected type is most common, because it has a much lower price-tag than the oil-free one (which you should only use if your application requires 100% oil-free air). Usually sturdy and able to resist harsh industrial environments, reciprocating air compressors can stay maintenance-free for quite some time and tend to have longer lifetimes. They truly care about their employees and customers and do all they can to make sure everyone is beyond happy with the services they provide. Small reciprocating and portable compressors are ideal for small job sites, whilst stationary rotary screw compressors provide much higher volumes of compressed air. In general, the recips will typically incur about twice the maintenance costs of a screw but seen over a 40 000 to 50 000 hour operation period, the maintenance costs will even out and the recips will typically incur 20 to 30% higher maintenance costs. A Reciprocating Compressor uses piston cylinder to compress the refrigerant gas. For air-conditioning applications the compressor will run off-design 99% of the time according to Standards. A reciprocating air compressor is probably the top option for your Nashville garage or Knoxville shop utilizing a lower volume. Screw compressors are much more compact than reciprocating compressors when we talk large capacities.
