Aspen Manufacturing Introduces LEM Series High-Efficiency, Multi-Position Aluminum Coil Air Handlers 

Humble, Texas, June 8, 2022 - Aspen Manufacturing, LLC (Aspen), one of the largest independent manufacturers of evaporator coils and air handlers for the residential and commercial residential heating, ventilation, and air conditioning (HVAC) marketplace in the United States and Canada, announces the introduction of the LEM Series high-efficiency, multi-position, aluminum coil air handlers.

The LEM Series offers outstanding installation versatility. The units are shipped as upflow or horizontal right and can be converted for downflow or horizontal left installations onsite by HVAC technicians. When a proper metering device is used, the LEM Series units are ETL listed for use with R-22 or R-410A refrigerants.  In addition, they can be AHRI certified with most brands of air conditioners or heat pumps. All LEM Series models are backed by a 10-Year Limited Parts Warranty with registration.

When properly installed and tested in accordance with ASHRAE standard 193, the sturdy, fully insulated galvanized steel cabinet offers less than 2% cabinet air leakage. A factory-provided knockout for duct return is standard on all LEM Series models, and all feature an easy access door for coil cleaning.

All LEM Series models feature a high-efficiency 120-volt ECM motor with factory-programmed software to control motor speeds and torques. Aspen’s proprietary software encoding allows the ECM motors to provide optimal performance and reliability. Rail-mounted blowers allow easy removal during service and routine maintenance by HVAC technicians. An electronic control board includes a blower time delay to maximize heat/cool extraction and offers an integrated fuse for additional protection.
