Carrier’s versatile packaged air-handling units satisfy design requirements with:
FEATURES / BENEFITSEasy-to-install and economical 40RU units provide reliable service.
- Multi-position design for horizontal or vertical installation without modification.
- Standard sloped drain pans and cleanable insulation treated with Environmental Protection Agency (EPA) registered antimicrobial agent improve indoor air quality.
- High-static design meets a wider range of applications than competitive packaged air handler lines.
- Ultra LOW LEAK Economizer accessory provides ventilation air and “free” cooling with built in Fault Detection and Diagnostic (FDD) capabilities.
- Cooling coils with mechanically bonded fins provide peak heat transfer.
- Hot water coil, steam coil, and electric heat accessories are available.
- Standard factory-installed thermo-static expansion valves (TXV) with removable power element on 40RUA units.
- Die-formed galvanized steel casings provide durability and structural integrity. Optional paint is available.
- Optional Staged Air volume (SAVt) system with 2-speed indoor fan VFD controller (07--30 models)
The 40RU Series air-handling units are the best choice for packaged air handlers. Model 40RUA units have direct-expansion coils. 40RUS units are chilled water packaged air handling units. All models offer excellent fan performance, a unique combination of indoor air quality features, easy installation, and affordable prices. Their versatility and state-of-the-art features will provide economical performance now and in the future.Indoor air quality features
The unique combination of features in the 40RU Series air handlers ensures that clean, fresh, conditioned air is delivered to the occupied space. Cooling coils prevent the build-up of humidity in the room, even during part-load conditions. Unit sizes of 10 tons and above feature dual-circuit face-split coils. Two-inch (51-mm) disposable filters remove dust and airborne particles from the occupied space. Thermal insulation contains an immobilized anti-microbial agent to inhibit the growth of bacteria and fungi. The anti-microbial agent is registered with the U.S. Environmental Protection Agency (EPA). Pitched drain pan can be adjusted for a right-hand or left-hand connection to provide positive drainage and prevent standing condensate.Economy
The 40RU Series packaged air handlers have low initial costs, and they continue to save money by providing reduced installation expense and energy-efficient performance. Quick installation is ensured by the multi-position design. Units can be installed in either the horizontal or vertical (upflow) configuration without modifications. All units have drain-pan connections on both sides, and pans can be pitched for right-hand or left hand operation with a simple adjustment. Fan motors and contactors are pre-wired and TXVs are factory-installed on 40RU models. High-efficiency, precision balanced fans minimize air turbulence, surging, and unbalanced operation, thereby cutting operating expenses. Economizer accessory precisely controls the blend of outdoor air and room air to achieve comfort levels. When the outside air is suitable, outside air dampers can fully open to provide “free” cooling. Economizer is an Ultra LOW LEAK design that includes return and outside air damper leakage that meets California Title 24 section 140.4 requirements. Controller meets California Title 24 Section 120.2 Fault Detection and Diagnostic (FDD) requirements.Rugged dependability
Die-formed galvanized steel panels ensure structural integrity under all operating conditions. Mechanically bonded coil fins provide improved heat transfer. Galvanized steel fan housings are securely mounted to a die-formed galvanized steel deck. Rugged pillow-block bearings (14 thru 30 size) are securely fastened to the solid steel fan shaft with split collets and clamp locking devices. Smaller unit sizes have spider-type bearings.Coil flexibility
Model 40RU air handling units have galvanized steel casings; inlet and outlet connections are on the same end. Chilled water coils have 1/2-in. (12.7mm) diameter copper tubes mechanically bonded to aluminum sine wave fins. All chilled water coils have non-ferrous headers. Direct expansion (DX) coils are designed for use with Puron® R-410A refrigerant and have copper tubes mechanically bonded to aluminum sine-wave fins. Direct-expansion coils include matched, factory-installed thermostatic expansion valves (TXVs) with matching distributor nozzles.Easier installation and service
The multi-position design and component layout allow for quick unit installation and operation. The DX coils have factory-installed TXVs with matching distributor nozzles. Units can be converted from horizontal to vertical operation by simply repositioning the unit. Drain pan connections are duplicated on both sides of the unit. The filters, motor, drive, TXVs, and coil connections are easily accessed by removing a single side panel.
