48GJ Single-Package Rooftop Units Electric Cooling/Gas Heating with Chlorine-Free Refrigerant

5 to 10 Nominal Tons

Carrier has designed the new Tierra™ Series based on customer needs to provide products that address several environmental concerns such as ozone layer depletion and global warming.

Features/Benefits

 First ''Ozone-Friendly'' rooftop line in the industry. Rooftops charged with R-407C chlorine-free refrigerant for zero ozone depleting potential. Industry's leading environmentally designed rooftop product line.

 High efficiency cooling performance with SEERs of 12.0 and EERs of 10.1 using scroll compressor technology.

 Most efficient rooftop line in the industry for heating. Dimpled heat exchangers with 2 stage gas valves on all units.

 Quietest sound operation in the industry-isolated compressor rails. All compressors mounted on independent vibration isolators. All compressors use the quiet scroll design. Standard belt-driven evaporator fan motors on all units.

 Unprecedented ease of maintenance achieved by self diagnostics on the Integrated Gas Unit Control Board (IGC), optional direct digital controls, standard size filters, no tool filter access, simple compressor access, complete compressor and exclusive gas heat anti-cycle protection, and permanently lubricated fan motors.

As the industry leader, Carrier's commitment to the environment has led to the development of alternate technology that is both safe for the environment and does not sacrifice customer comfort or energy efficiency. The new refrigerant, R-407C, is specially designed for both zero ozone depletion and high-efficiency performance. R-407C is an HFC (hydrofluorocarbon) and does not contain chlorine, which is present in HCFCs (hydrochlorofluorocarbons) that destroy the ozone layer. The new chlorine-free refrigerant has virtually identical operating pressures as R-22. This allows Carrier to use the same high efficiency design of the 48HJ Weathermaster rooftop line. The 48GJ units operating efficiencies attain SEERs (Seasonal Energy Efficiency Ratios) as high as 12.0 and EERS (Energy Efficiency Ratios) as high as 10.1. This allows the Tierra™ series to qualify for most utility rebate programs and most demand side and peak electrical load reduction programs. This high efficiency results in the Tierra series consuming less power and fossil fuels than standard efficiency equipment. These lower emissions (resulting in a reduction in greenhouse gases) and zero ozone depletion make the Tierra series the ozone friendly solution.
