Shipping: These units are heavy, and as such, we have quoted a shipping price based on the unit shipping out on a pallet through a freight company. If we can find a cheaper way to ship the unit, we will do so. If the buyer wants to arrange their own shipping, this is welcome as well. Duties may apply to orders being shipped over the border. Item is shipping from Canada. About Copeland Scroll Compressors: Scroll Compressors When Emerson first pioneered the use of scroll technology in compressors, it changed the industry forever. Since then, Copeland Scroll® technology remains at the forefront for HVACR applications, impressing contractors and original equipment manufacturers (OEMs) with its superior efficiency, proven reliability and ease of installation. With the broadest product line in the industry, Copeland Scroll compressors range from 1-60 HP and are installed in more than 80 million locations around the world. They have become the compressor of choice to lead the industry through major transitions, including the 13 SEER minimum-efficiency requirement and R-22 phaseout. Copeland Scroll compressors can be used in single or tandem configurations and can also be modulated for increased efficiency and homeowner comfort.How Scroll Compressors Work The Copeland Scroll compressor has one scroll, or spiral, orbiting in a path defined by a matching fixed scroll. The fixed scroll is attached to the compressor body.
The orbiting scroll is coupled to the crankshaft and orbits, rather than rotates. The orbiting motion creates a series of gas pockets traveling between the two scrolls. On the outer portion of the scrolls, the pockets draw in gas, and then move into the center of the scroll, where the gas is discharged. As the gas moves into the increasingly smaller inner pockets, the temperature and pressure increase to the desired discharge pressure.
Better Liquid Handling Axial and radial compliance allow the scroll members to separate in the presence of liquid refrigerant, thus, providing protection against liquid damage
Greater Efficiency More efficient over their entire operating range
Improved Sound Operate at lower sound and vibration levels than traditional compressors
Unmatched Reliability
