High efficiency models, available from 7.5- to 10-tons in gas/electric and electric/electric configurations, offer more than 100 field-selectable options to meet a variety of applications. Each unit can be made up to 25 percent more efficient with the addition of an optional, single-zone VAV (Variable Air Volume) supply fan. All K-Series HVAC units come standard with an Eco-Last Coil System that uses up to 52 percent less refrigerant, are up to 59 percent lighter and have up to 20 percent fewer brazed joints than standard units for increased efficiency and cost savings.
For added installation and service convenience, K-Series models offer several features designed to reduce time on the job. They include an isolated compressor for fast, accurate charge diagnostics; a slide-out blower that allows for quick and easy cleaning, belt adjustment and parts replacement; and an easy-to-reach gas compartment for quick and easy analysis and service.
The new K-Series models offer efficiencies of up to 12.7 EER and 13.2 SEER, compared to standard K-Series units offering efficiencies of up to 11.4 EER and 13.2 SEER.
Warranties offered on the K-Series rooftop HVAC units include a 15-year limited warranty on the stainless steel gas heat exchanger, a 10-year limited warranty on the aluminized gas heat exchanger, a five-year limited warranty on the compressor, a three-year limited warranty on the Eco-Last Coil System and a 1-year limited warranty on all covered components.
