Dual-circuit portable chillers have a tandem scroll compressor arrangement for dual-circuit capacity control. Iceman Dual Circuit is suited for applications with varying cooling load requirements, or when future growth is planned and only a portion of the chilling is needed today. The tandem design provides down to 10 percent of overall capacity for smaller applications, offering greater efficiency. For larger applications requiring more capacity, both circuits work together to meet the need of the process. It is available in 10 to 40 ton cooling capacities.
