Carrier Transicold’s new Fourward series of both Vector Hybrid and X-2 belt-driven refrigeration units is designed to improve operating efficiencies while also incorporating emissions control reduction technology to meet U.S. Environmental Protection Agency Tier 4 standards
Much of the improvement came through sophisticated engineering of refrigeration components like the evaporator and condenser. These “micro-channel” heat exchangers need less compressor head pressure to force the refrigerant through the system, and the thinner coils they incorporate require less horsepower from the fans; an electronically controlled expansion valve helps. All are coordinated with the Apex control system, which now has more sophisticated algorithms to optimize all the factors for efficiency. Noise levels also are reduced, in part because of the reduced power needed from the fans.
