Scroll compressors are positive-displacement devices that work by internal compression. [5][1] They were not commercially produced for air conditioning until 1983 when Hitachi launched the world's first air conditioner with a hermetic scroll compressor. Free postage. Oilless Scroll Air Compressors are the way to go for operations that require pure air. Léon Creux first patented a scroll compressor in 1905 in France and the US (Patent number 801182). [2] Creux invented the compressor as a rotary steam engine concept, but the metal casting technology of the period was not sufficiently advanced to construct a working prototype, since a scroll compressor demands very tight tolerances to function effectively. It is commonly used in fridges and freezers to pump around the freon. They are generally defined as positive displacement devices having orbital motion and interleaving scrolls used to compress, pump, or expand fluids. Hier finden Sie alle Produktinformationen im Überblick >>, Krinner Drucklufttechnik GmbHFriedrich-Bergius-Str. This air compressor use scroll technology that results in a noise output as low as 63dBs*, making it the quietest compressor … If the compressor is designed to operate near a single operating point, then the scroll compressor can actually gain efficiency around this point if there is no dynamic discharge valve present (since there are additional discharge flow losses associated with the presence of the discharge valve as well as discharge ports tend to be smaller when the discharge is present).[19][20]. Some compressors use the pressurized discharge gas to push both scrolls together, eliminating the need for tip seals and improving sealing with use; these compressors are said to wear-in instead of wear-out,[14][15][16][17] but other parts such as the Oldham ring can still wear out. Kontinuierlich wird die angesaugte Luft in den immer enger werdenden Innenraum gedrückt, wodurch pulsationsfreie, … What is scroll technology? That remnant gas from the last cycle then occupies space intended for suction gas. Typically, an air-conditioning scroll does not have a dynamic discharge valve. The presence of multiple cylinders in reciprocating compressors reduces suction and discharge pulsations. This is the best place to start for a basic understanding of the technology behind Air Squared. [22], In 2006 a major manufacturer of food service equipment, Stoelting, chose to change the design of one of their soft serve ice cream machines from reciprocating to scroll compressor. An eccentric shaft can provide the orbital motion but the scroll must be prevented from rotating, typically with an Oldham-type coupling, additional eccentric idler shafts, or a bellows joint (particularly for high-purity applications). [21] The scroll compressors are more efficient in this case because they do not have a dynamic discharge valve that introduces additional throttling losses. Die SF-Scrollkompressoren stehen für Zuverlässigkeit und Qualität. [citation needed]. A scroll compressor is a uniquely designed device that compresses gas through internal compression using two inter-fitting scrolls. They found through testing that the scroll compressor design delivered better reliability and energy efficiency in operation.[23]. This creates a continuous flow of air. The new SCROLL series combines creative ingenuity with advanced engineering to provide a top quality, oil-free compressed air solution. Many residential central heat pump and air conditioning systems and a few automotive air conditioning systems employ a scroll compressor instead of the more traditional rotary, reciprocating, and wobble-plate compressors.

When efficiency, quiet operation, low maintenance and a small footprint are critical, Scroll Air Compressors are the smart choice. [3] However, the scroll expander engine could not overcome the machining hurdles of radial compliance inherent to achieving efficiency in scroll operation that would not be adequately addressed until the works of Niels Young in 1975. It is commonly used in fridges and freezers to pump around the freon. £5.16. They have casings filled with lubricant to prevent abrasion of the exterior of the pump tube and to aid in the dissipation of heat, and use reinforced tubes, often called 'hoses'. $200.00 shipping. Another method for producing the compression motion is co-rotating the scrolls, in synchronous motion, but with offset centers of rotation. SCROLL series is 100% oil-free and is equipped with a high efficient IE 3 Motor and operates with 61 db(A) (SCROLL 04) at low noise level and low vibration.
