SmartComfort PAM4 Single-Packaged Air Conditioner System with R-454B Refrigerant Single Phase 2 to 5 Nominal Tons (Sizes 024-060)

Features / Benefits

Application:
This unit is a packaged air conditioner designed for manufactured housing, residential, and light commercial applications. It reflects our commitment to developing the finest air conditioners that modern technology can offer.

Cabinet Design:
Built in one basic cabinet size with round or rectangular side-by-side duct configuration.

Refrigerant:
Uses R-454B, the latest refrigerant meeting the 2025 GWP requirement. The unit is tested and designed with R-454B and includes a dissipation system for added safety.

Factory-Assembled Package:
A compact, fully self-contained electric cooling unit with horizontal supply and return ducts. Available in a variety of standard cooling sizes to meet both residential and light commercial needs. Designed for easy installation on a ground-level pad.

Easy to Install:
Compact, lightweight unit with an identical 32 x 51-in. (813 x 1295 mm) footprint for all sizes. Uses less sheet metal, making it lighter and easier to handle. Built-in handholds on the unit basepan simplify positioning on the job site.

Aerodynamic Fan Blade Design:
Reduces overall sound levels, operating as quietly as 70 dBA.

Service Access:
Designed for quick installation and maintenance with access from both the side and front. Routine tasks like coil cleaning are simplified with multiple side access panels.

No-Rust Basepan with Integrated Drain Pan:
Standard on all units. Made of a tough, high-tech composite material that prevents rust and eliminates premature basepan replacement.

Durable Pre-Painted Steel Cabinet:
Provides protection against harsh weather. The watertight and corrosion-resistant finish helps the unit maintain a like-new appearance. The cabinet includes a louvered coil enclosure for added protection from vandalism and hail.

Indoor Air Quality:
Sloped drain pan minimizes standing water, helping prevent mold and mildew. Made of rust-proof material that resists deterioration and won’t release foreign particles into the airstream.

Lightweight, Compact Construction:
Ideal for residential and manufactured housing. One of the lightest packaged units available, weighing only 244 lb (111 kg) for the 024 size. The low-profile design reduces ductwork needs and keeps the unit discreet.

Structural Design:
Uses a structural beam design to form all four sides of the cabinet. Only 12 unique sheet metal parts are used, simplifying construction and improving reliability.

Efficient, Dependable Performance:
Features durable compressors designed for high efficiency. Offers up to 13.4 SEER2 cooling efficiency, which may reduce energy expenses by up to 30% compared to older models.

Durable, Dependable Compressors:
Hermetically sealed for protection and long life. Includes internal overcurrent protection and vibration isolation for quiet operation.

Direct-Drive Multispeed Blower Motor:
Standard on all models. Delivers high efficiency and strong airflow performance compatible with most duct systems.

Direct-Drive PSC Condenser-Fan Motors:
Helps reduce energy usage and allows for cooling operation down to 40°F (4.4°C).

Refrigerant System:
Built for reliability with factory-charged R-454B (non-ozone depleting, low GWP). Includes liquid refrigerant filter driers, service connections for easy pressure checks, and factory-installed leak detection dissipation system.

Air Handling Leakage:
Cabinet air leakage is less than 2.0% at 1.0 in. W.C. and less than 1.4% at 0.5 in. W.C., tested per ASHRAE Standard 193.

Accessory Electric Heaters:
Optional electric heater modules available. Installed on the blower inlet with remote-mounted controls for flexibility.
