Carrier Transicold has enhanced the dehumidification capabilities of its PrimeLine refrigeration container units, enabling them to maintain relative humidity (RH) levels as low as 50 percent with no compromise in energy efficiency. The PrimeLine unit was developed to help shipping lines conserve fuel and reduce emissions related to shipboard power generation.
Low RH is important for shipping certain types of produce, such as ginger and other root crops, onions, garlic, and flower bulbs. Keeping things dry can also be helpful when shipping paper products, artwork, pharmaceuticals, electronics, and even certain metals that might be prone to surface staining.
Thanks to the PrimeLine unit's electronic expansion valve, the dehumidification enhancement was done entirely through sophisticated software algorithms. No change to the mechanical design was required. This enhanced capability can also be added to existing PrimeLine models when users upgrade to the latest control software.
The PrimeLine units offer exceptional pull-down capability and high deep-frozen capacity for units using non-ozone-depleting R-134a, the refrigerant with the lowest global warming potential of all contemporary container refrigerants.
