Advanced HVAC Solutions
VARIABLE-SPEED TECHNOLOGIES
Model L units feature a lead variable-speed compressor and variable-speed blower to maintain a constant discharge air and room temperature to efficiently deliver complete comfort.
- HUMIDITROL+
- Humiditrol+ is a modulating hot-gas reheat dehumidification system that can vary the sensible and latent capacity of the Model L unit to better match the dehumidification demand of the space.
- ENHANCED DEHUMIDIFICATION MODE
- Model L units are enabled with enhanced dehumidification (EDH) mode, which is designed to provide additional dehumidification when both cooling and dehumidification demands are present.
- DIRECTPLUS™ BLOWER
- 3-12.5-ton Model L units are equipped with a direct-drive, variable-speed blower that eliminates maintenance and service costs associated with traditional belt-drive motors.
Ultimate IAQ System
Factory or Field Installed
- Healthy Climate® High-Efficiency Air Filters
- Disposable MERV 8, MERV 13, or MERV 16 (Minimum Efficiency Reporting Value based on ASHRAE 52.2) efficiency 2-inch pleated filters
- Needlepoint Bipolar Ionization (NPBI) Kit
- NPBI technology integrates with system controls for effective air treatment Ionization has been shown to effectively reduce harmful pathogens, pollutants, and odors. Brush-type ionizer introduces a high concentration of both positive and negative ions into the air stream
- These bipolar ions are then dispersed into the occupied space through the duct system proactively reducing the airborne contaminants.
- Ions travel within the building air stream and attach to particles, pathogens, and gas molecules, making them larger and easier to capture in the filtration system
- UL 2998 certified for zero ozone emission
- Healthy Climate® UVC Germicidal Lamps
- Germicidal lamps emit ultra-violet (UV-C) energy, which has been proven to be effective in reducing microbes such as viruses, bacteria, yeasts, and molds. This process either destroys the organism or controls its ability to reproduce
- UV-C energy greatly reduces the growth and proliferation of mold and other bioaerosols (bacteria and viruses) on illuminated surfaces (particularly the coil and drain pan)
