Mokon introduced an energy-efficient Iceman SM series of modulating portable chillers in 5-, 10- and 15-horsepower capacities at NPE2012.
The line uses the Copeland Scroll-brand digital compressor, which can provide variable horsepower output from 10-100 percent by axially separating internal scroll members, said Ray Cracknell, engineering technician with Mokon in Buffalo, N.Y.
The compressor operates in loaded and unloaded phases depending on demand requirements. In the loaded phase, the bypass solenoid valve is closed and the compressor delivers full capacity. In the unloaded phase, the valve is opened, resulting in minimal or no capacity through the compressor.
Units in the Iceman SM series are ready for shipment, Cracknell reported.
