Lennox launches three-phase nitrogen-charged air conditioner and heat pump units

Dallas, TX – (March 22, 2012)Three-phase nitrogen-charge split system air conditioners and heat pumps are now available from Lennox. Offered as replacement units for 3- to 5-ton equipment that currently uses R-22 refrigerant, these nitrogen-charged products are designed to accommodate ambient temperatures up to 125ºF.

The units feature a nitrogen-charged, high-efficiency scroll compressor that is grommet-mounted for quiet operation and protected internally against high-temperature motor overload conditions. Enhanced aluminum fins and copper tubing coils offer high efficiency and capacity; a raised design prevents debris from collecting in the bottom of the coil, preventing loss of airflow.

Both the air conditioner and heat pump units are built with a heavy-duty galvanized steel cabinet coated with a baked polyester paint finish for maximum durability. The design also includes a full metal louvered panel coil guard and rounded safety corners. Controls located in the corner post and external gauge ports offer easy installation and service. Finally, a raised base pan with ports installed with the air conditioner offers excellent water and debris drainage.

Additional features of the new nitrogen-charged split system air conditioners and heat pumps include a discharge muffler for quiet operation, and a bi-directional filter drier for long-lasting durability and system protection. Easily accessible service valves allow quick installation and easy cleaning and service, while a low-pressure switch protects against loss of charge. Trade-available components are offered on both air conditioner and heat pump units.

Finally, the heat pump unit is also equipped with a reliable, solid-state, time-initiated, temperature-terminated defrost system with a field-selectable defrost cycle in 30-, 60- or 90-minute increments. The system is also equipped with Quiet-shift™ capable defrost control, short-cycle compression protection and built-in diagnostics to help contractors save time on the job.

A 1-year warranty on parts and 5-year compressor warranty are included.
