A partnership with McQuay Intl. results in the RTCW frictionless chiller, achieving a 35 percent savings over rotary screw designs. A digitally controlled magnetic bearing system, consisting of both permanent magnets and electromagnets, replaces conventional lubricated bearings. The frictionless compressor shaft is the compressor's only moving component. With two independent centrifugal compressor circuits and shell and tube evaporator and condenser components, the units range in size from 120-190 ton capacity.

Freezing on contact
The Frigoscandia SuperContact contact freezer quick-freezes the surface of a wide range of delicate food products using an ingenious method to freeze food: products are conveyed on a thin polyethylene film running over a refrigerated plate. The underside of the product gets a stabilizing crust. It is hard enough to allow the product to be transported onto a regular freezer belt with no mesh marks or sticking problems.
