Dometic's Blizzard Turbo auxiliaary ACThe new Blizzard Turbo from Dometic is claimed to be the industry’s coolest and most powerful auxiliary air conditioner for trucks.

As anti-idling laws become the norm across the country, engine-off auxiliary air conditioning becomes more and more attractive for drivers’ comfort when resting, the company says.

Powered by batteries, generator, or shore power, the Blizzard Turbo provides 7000 BTUs of cooling. In lab tests, says Dometic, it outperformed competing models that claim to provide up to 10,000 BTUs.

It’s a split system that puts the noise of the condenser unit on the outside of the truck while the quieter evaporator unit blows cool air within the cab interior.

Improving on previous models, the new air conditioner includes a higher efficiency dual-circuit evaporator coil, improved base pan design for efficient condensate drainage, internal electrical box with easy-start circuitry to minimize starting-current surge, and easy-access high- and low-pressure service ports on the exterior unit.

A key new addition is a centrifugal blower, providing high air flow and high static-pressure performance. It’s rotatable for vertical or horizontal discharge, which increases installation options.

Dometic says it has also improved compressor bracing and vibration dampening for a quiet ride and extended component life. For convenient service anywhere, Dometic designed the Blizzard Turbo to operate with R-134A refrigerant, the most commonly available refrigerant.

Dometic has also made advances to the condenser, which include increased side inlet openings for improved air flow, a 12 VDC fan to allow use of a smaller  transformer and an optimized electrical box. This new system will continue to offer Dometic’s patent protected use of quick-disconnect refrigerant fittings.

Designed for the harsh trucking environment, both the interior and external components of the Blizzard Turbo are vibration- and corrosion-resistant and have improved mounting and fastening.
