AFW Series High Efficiency Wall Mount Hydronic Heat Air Handlers
Features and Benefits
APPLICATION VERSATILITY
Front or bottom return air. Offset hanging brackets attach to unit and wall to allow hanging inside closet. Can be AHRI matched with most brands of air conditioners or heat pumps.
• A2L refrigerants require a Refrigerant Detection System (RDS) for compliance. In accordance to UL 60335 Refrigerant Detection Systems are factory-installed on A2L refrigerant ready air handlers.
• ETL listed for R22 and 410A. ETL listed for R454B and R32 with (RDS) Refrigerant Detection System.
120V Constant Torque ECM Motor (Hydronic Heat)
Constant torque ECM speeds and torques are controlled by embedded motor software and factory pre-programmed. Direct drive blowers circulate air quietly and efficiently. Air moving system is plated mounted to allow for easy removal and service.
LOW LEAKAGE CABINET
Less than 1.4% air leakage from cabinet when tested in accordance with ASHRAE standard 193. Unit must be installed according to Aspen installation instructions. Sturdy, fully insulated galvanized steel cabinet; stick pins ensure 1/2” insulation remains in place. Unit ships with disposable filter.
MODULAR HYDRONIC HEAT KITS
Heat kits available with either circuit breakers or terminal blocks.
Available in 2, 3 & 4 row, providing 16,000 to 59,000 BTU’s of heat. Heat kits are ordered factory-installed. Freeze stat is standard, wired into circulating pump control circuit. Controls are accessible from the front for easy service. Electrical connections can be made from the top or left. Disconnect does not protrude through the wall panel. Fan time delay relay standard for increased efficiency. Heat kits are available with or without circulating pump and check valve. Units are provided with auxiliary relay for remote pump. Schrader ports are standard on water-out manifold, hose bib available as an option. Totally lead free constructed coil. Suitable for potable applications.
BLOWER
Direct drive multi-speed blowers circulate air quietly and efficiently. Motor speeds can be easily selected via motor terminals. Swing mounted blowers can be easily removed for service.
ELECTRONIC CONTROL BOARD
An electronic board controls the functioning of the system reducing moving parts. The board provides for various hot water supply source connections and the blower time delay to maximize heat/cool extraction. As an enhanced feature the pump circulates hot water every 6 hours to prevent water stagnation.
DX COIL
High efficiency rifled copper tubes/enhanced aluminum fins provide maximum heat transfer. All coils immersion tested at 500 psi then nitrogen pressurized and factory sealed for maximum reliability. Liquid-line Schrader allows pre-installation pressure testing. Available with either check style flowrator or TXV metering device. Field-installable TXVs are also available. Galvanized metal drain pan with bottom primary and secondary drain connections or alternate right side primary. All connections 3/4” FPT. Access door allows for coil cleaning.
WARRANTY
Five-year limited parts warranty with registration.
