Carrier freezes out excessive noise with new refrigeration unit

ATHENS, Ga. — In its own quiet way the Supra 950 truck refrigeration unit boasts the highest output of any truck unit made by Carrier Transicold, while its sound output is significantly lower than its predecessor from Carrier.

The new diesel-powered unit completes a two-year transformation of Carriers single-temperature truck refrigeration line, which also includes the Supra 550, 650, 750 and 850.

It will be a favourite 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, said David Kiefer, Carrier Transicolds product manager Truck Products. At 100oF ambient with its setpoint at 35oF, the Supra 950s cooling capacity is a huge 32,000 BTUs.

Sporting a new skin package with a contemporary appearance, the Supra 950 units exterior is made of a composite material that is 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.

Besides giving it great looks and quieter operation, we also improved the unit for easier maintenance and service access, added Kiefer. Basic inspections can be performed without opening doors or removing panels. Operators and technicians can easily check the engine oil level, check and add engine coolant and inspect the refrigerant level without opening the unit. Grab bars attached to the frame on both sides 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 deliver high-capacity refrigeration while running at relatively low speeds, reducing wear and tear on the mechanical system and conserving fuel.
