Designed for multi-temperature trailer applications, the new Vector 1800MT refrigeration unit from Carrier Corp. is the first to use hybrid diesel electric technology. The company’s patented Deltek technology is said to offer unprecedented system reliability and performance, plus an estimated 30% reduction in maintenance costs. As well, the Vector 1800MT is the first multi-temp system to use Carrier’s Advance microprocessor control, which delivers precise refrigeration control, driver set-up ease, and exclusive
fuel-optimization options, the company says.

By expanded use of electronics and maintenance-free electrical components, the Vector eliminates two-thirds of the serviceable
mechanical components found in conventional systems — such as idler pulleys, vibrasorbers, most belts, fan shafts, the compressor
shaft seal and clutch — while using only half the refrigerant charge compared to conventional systems.

Other features: built-in electric standby capability for fuel savings, emissions and noise reduction, and regulatory compliance at the
loading dock; 100% electric heat, instead of hot gas, for constant heating capacity independent of ambient temperature; and less noise thanks to the elimination of many mechanical components and optional ‘Stealth’ components.

The unit employs three major components to deliver refrigeration and heating: 1) a direct-injection Kubota diesel engine; 2) an
aircraft-quality, high-performance electric generator; and 3) an electrically driven sealed compressor.

The system lends itself well to electric standby, Carrier says, which is why the 1800MT comes with built-in 460-volt plug-in capability.

Especially important in urban distribution, facilities can tap into standby power for emissions and noise abatement as well as fuel savings.
