Carrier’s easy-to install and economical 40RF/40RU units provide reliable service and versatile packaged airhandling units satisfy design requirements with:
Multi-position design for horizontal or vertical installation without modification.
Standard sloped drain pans and cleanable insulation treated with an immobilized anti-microbial agent to inhibit the growth of bacteria and fungi on the insulation.
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 thermostatic expansion valves (TXV) with removable power element on 40RFA/40RUA units.
Die-formed galvanized steel casings provide durability and structural integrity. Optional paint is available.
Upgraded unit control board with intuitive indoor fan adjustment.
Standard Staged Air Volume (SAV™) system.
Indoor air quality features
The unique combination of features in the 40RF/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 partload conditions. Unit sizes 10 tons and above feature dual-circuit face-split coils. 2 in. (51 mm) disposable filters remove dust and airborne particles from the occupied space. Pitched drain pan can be adjusted for a right-hand or left-hand connection to provide positive drainage and prevent standing condensate. 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.
Economy
The 40RF/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 prewired and TXVs are factory-installed on 40RF/40RU models. High-efficiency, precision balanced fans minimize air turbulence, surging, and unbalanced operation, thereby cutting operating expenses.
Rugged dependability
Die-formed galvanized steel panels ensure structural integrity under all operating conditions. Mechanically bonded coil fins provide improved heat transfer. For 40RU units, galvanized steel fan housings are securely mounted to a dieformed galvanized steel deck. Rugged pillow-block bearings (40RU sizes 14-30) are securely fastened to the solid steel fan shaft with split collets and clamp locking devices. 40RF units (sizes 07-12) have spider-type bearings. This air handling unit has thermal insulation containing an immobilized antimicrobial agent to inhibit the growth
Coil flexibility
Model 40RF/40RU air handling units have galvanized steel casings; inlet and outlet connections are on the same end. Chilled water coils have 1/2 in. (12.7 mm) 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
With the new EcoBlue™ Vane Axial fan system, there is no longer a need to adjust belts or pulleys as in past designs. This frees up maintenance and installation time. 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. There are simple, fast plug-in connections to the standard integrated unit control board (UCB). The UCB has clearly labeled connection points to reduce installation time. Also, a large control box provides room to work and mount Carrier accessory controls. 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.
EcoBlue™ Technology
The direct drive EcoBlue Technology indoor fan system on 40RF units uses a Vane Axial fan design and electronically commutated motors. This new Vane Axial design over past belt drive systems has 75% fewer moving parts, uses up to 40% less energy and has no fan belts, blower bearings and shaft.
Easy to use
The newly re-designed Unit Control Board by Carrier puts all connections and troubleshooting points in one convenient place. Most low voltage connections are made to the same board and make it easy to access it. Setting up the fan is simple by an intuitive switch and rotary dial arrangement.
Staged Air Volume (SAV™) system
Our SAV units will automatically adjust the indoor fan motor speed in sequence with the unit's cooling operation. Per ASHRAE 90.1 2010 standard section 6.4.3.10.b, during the first stage of cooling operation the fan motor (either ECM or controlled by VFD) will adjust to provide two-thirds of the total cfm established for the unit. When a call for the second stage of cooling is required, the fan motor will allow the total cfm (100%) established for the unit. During the heating mode the fan motor will allow total design cfm (100%) operation and during the ventilation mode the fan motor will allow operation to two-thirds of total cfm.
