Key Features
-
High Efficiency
Unit is designed to meet or exceed ASHRAE 90.1-2004 standards. -
Comfort/ IAQ
Corrosion-resistant, removable, double-sloped drain pan provides application flexibility, durability and improved serviceability.
With Cooling Only units, it is possible to field install an electric heating unit on an existing unit and convert it to a heat pump at a later date. Helix wound nichrome elements are used for this purpose.
An individual element limit control provides better control over your air conditioning needs. -
Serviceability
Hinged access panels provide quick access to components and protect panels and roof from damage during servicing.
Full-perimeter base rail provides greater structural integrity, so the unit is easier to handle when rigging and transporting.
Isolated compressor compartment allows performance check during normal compressor operation without disrupting airflow.
Fork slots on three sides make it easy to pick up and transport units from almost any angle.
Independent motor mount allows for easy and efficient service access without removing the top panel. -
Reliability
Pre-defined supply fan motor/drive combinations make selecting components to meet static and airflow requirements quick and easy.
Thermostatic expansion valves provide peak cooling performance across the entire application range.
Scroll compressor provides reliable, long-term operation.
