In its own quiet way, the Supra 950 truck refrigeration unit boasts the highest output of any truck unit made by Carrier Transicold, the company says. Not only is the Supra 950 a cooling capacity leader, but Carrier — a business unit of United Technologies Corp. — says its sound output is significantly lower than its predecessor.
The Farmington, Conn.-based company says the new diesel-powered unit completes a two-year transformation of its single-temperature truck refrigeration line, which also includes the Supra 550, 650, 750 and 850.
“It will be a favorite for frozen applications, such as ice cream, and for the leasing industry, where the varying demand on the daily rental trucks requires a refrigeration unit with the highest capacity,” says David Kiefer, who directed the product line upgrade as Carrier Transicold’s product manager for truck products. “At 100 degrees Fahrenheit ambient with its setpoint at 35 degrees, the Supra 950’s cooling capacity is a huge 32,000 BTUs.”
Sporting a new “skin” package with a contemporary appearance, the Supra 950 unit’s exterior is made of a composite material designed to be lightweight, damage-resistant and easy to clean. Like others in the series, the Supra 950 was acoustically engineered to significantly reduce sound output. A new all-composite bottom panel seals against the housing, helping to buffer and redirect engine noise, Carrier says.
“Besides giving it great looks and quieter operation, we also improved the unit for easier maintenance and service access,” Kiefer says. Basic inspections can be performed without opening doors or removing panels, and operators and technicians can easily check the engine oil level, check and add engine coolant and inspect the refrigerant level without opening the unit, Carrier says. Grab bars attached to the frame on both sides are designed to provide secure, convenient grips for service technicians.
The Supra 950 unit uses a 1.1-liter CT3-69 TriVortex diesel engine and a 6-cylinder compressor. The large engine and compressor are designed to deliver high-capacity refrigeration while running at relatively low speeds, reducing wear and tear on the mechanical system and conserving fuel. For even greater fuel savings, the Supra 950 unit can be optionally equipped with an electric standby motor that also helps reduce noise and eliminate exhaust emissions at the loading dock.
All Supra units are controlled by the Cab Command microprocessor with a driver-friendly in-cab digital readout, Carrier says. For more information, go to www.trucktrailer.carrier.com.
