Features/Benefits

Industry-leading cooling EERs The 48HJ015 (13 tons) and 017 (15 tons) units provide leading ARI (Air Conditioning and Refrigeration Institute) certified cooling EERs (Energy Efficiency Ratios) of 10.5 and 10.3, respectively. The fully-rated 20-ton 48HJ025 has an EER of 9.3. These exceptionally high ratings assure minimum operating costs.

Semi-hermetic compressors All three 48HJ units use the Carlyle 06D semi-hermetic compressors. These serviceable compressors are highly regarded, preferred by owners and users, and offered exclusively on the Carrier high-efficiency 13 to 20 ton HJ units. Two 06D semi-hermetic compressors on independent refrigeration circuits are offered on the 48HJ017 and 025 units for 2 steps of capacity control and redundancy. A single 06D semi-hermetic compressor with unloading capability is offered on the 48HJ015. All compressors have service valves and a full complement of safety devices, including high and low pressure switches, over temperature protection, an electronic cooling lockout device, and crankcase heaters.

High static oversized fan motors and variable pitch belt drives The 48HJ units have oversized evaporator fan motors and variable pitch belt drives supplied standard from the factory to provide up to 2 in. wg of external static pressure at 400 cfm per ton with wet coils and clean filters installed. A 5 hp motor is provided standard on the 48HJ017 (15-ton unit), and a 10 hp motor is standard on the 48HJ025 (20-ton unit).

Easy installation The 48HJ 13 to 20 ton rooftop units are perfect for vertical supply and return roof curb mount installation on new construction, retrofit, and replacement applications. The unique industry leading compact size and weight are favored by designers, contractors, owners, and users. The compact physical size and weight are not only advantages in terms of minimizing required roof structures on new construction and retrofit jobs, but also make the 48HJ the perfect replacement unit for any of the original Carrier 48DP,DR 012-020 units installed in the late 1970s and early 1980s to meet the upgraded job requirements of the 1990s.
