Carrier Transicold, a provider of industry-leading transport temperature control, is proud to introduce, through its Container Products Group, the PrimeLINE container refrigeration unit — designed specifically to reduce environmental impact and lifecycle cost through exceptional efficiency. Unveiled at the Intermodal 2007 event (4th – 6th December) held in Amsterdam, the PrimeLINE unit is distinguished by its unique features, including design enhancements that simultaneously boost cooling capacity and energy efficiency.

The PrimeLINE uses R-134a, the standard refrigerant throughout Carrier's container product line. While more energy efficient, the PrimeLINE unit takes a 'no compromises' approach to performance with best-in-class pulldown capacity – nearly 10 percent better than its nearest rival. It has the highest deep-frozen capacity of any unit with R-134a. At ambient temperatures of 38ºC (100ºF) and box temperature of -29ºC (-20ºF), it offers cooling capacity of 4,400 watts (15,000 Btu/hr.). Numerous design enhancements contributed to the efficiency of the PrimeLINE unit. Topping the list is the first digital scroll compressor developed for use with R-134a, which came from a collaboration between Carrier and the Copeland team at Emerson Climate Technologies.

Additional platform enhancements include an efficiency-boosting redesign to the evaporator fan and stator with blades optimized to exceptional levels of efficiency. According to the company’s press release, boosting the cooling capacity is a larger condenser coil, as well as other design enhancements made possible through computer modeling at Carrier’s engineering center. The PrimeLINE unit complements Carrier’s core container refrigeration family, which also includes the industry-leading EliteLINE scroll compressor unit, the ThinLINE reciprocating compressor unit, the StreamLINE unit for 20-foot containers and the ThinLINE DT convertible dual-temperature refrigeration system.
