Carrier Transicold has introduced three new diesel-powered truck refrigeration units — the Supra 650, 750 and 850 — designed for protection of perishable and frozen food and other refrigerated cargo in medium to large trucks.

The units are built within a contemporary housing that dramatically reduces sound levels by nearly half compared to previous models, Carrier says. The acoustically designed housing is manufactured using a composite material designed to be damage-resistant and easy to clean, including a bottom panel engineered to improve sound quality.

“The sound output of the new Supra series is about as low as previous models equipped with a noise-reduction package,” says Dave Kiefer, product manager of truck products for Athens, Ga.-based Carrier Transicold, a business unit of United Technologies Corp. “For many users, additional abatement devices now will not be necessary. However, if ultra-quiet operation is required, the Stealth noise abatement option takes the new Supras to even lower levels, and at a reduced price, providing the customer with greater value.”

According to Carrier, the new design also makes maintenance easier by allowing basic service inspections without having to open doors or remove panels: The operator now can check engine oil level, check and add engine coolant and inspect the refrigerant level without opening the unit. New handles attached to the frame on both sides of the unit provide secure, convenient grips for service technicians.

Supra units use the CT3-44 TriVortex diesel engine and either a 2-cylinder or 4-cylinder compressor, depending on the model of the unit. All units in the series are controlled by the Cab Command microprocessor with an in-cab digital readout. All Supra units also have an electric standby motor option for reduced noise and exhaust emissions at the loading dock and for compliance with applicable environmental regulations.
