ORLANDO, FLA. (April 6, 11 a.m. ET) — Circulating liquid temperature control systems developer Mokon (Booth 3363) introduced an energy-efficient Iceman SM series of modulating portable chillers in 5-, 10- and 15-horsepower capacities.
The line uses the Copeland Scroll-brand digital compressor, which can provide variable horsepower capacity output from 10-100 percent by axially separating internal scroll members, said Ray Cracknell, engineering technician with Mokon in Buffalo, N.Y. Mokon uses chillers only from Copeland, an operation of Emerson Electric Co.’s climate technologies business.
The compressor operates in loaded and unloaded phases depending on load demand requirements. In the loaded phase, the bypass solenoid valve is closed, and the compressor delivers full capacity. In the unloaded phase, the bypass solenoid valve is opened resulting in minimal or no capacity through the compressor.
In late 2011, “we saw a need in our chiller line,” Cracknell said.
Mokon was aware that Copeland had created energy-efficient compressors with digital technology for the residential market several years ago. Mokon adopted the technology once Copeland made the compressors available for the industrial market.
Units in the Iceman SM series are ready for shipment, Cracknell reported.
