AHRC18/AHRR18 Design Features
SPLIT SYSTEM AIR HANDLING UNIT
HIGH PERFORMANCE AIR HANDLING UNIT WITH AN IMPENETRABLE INTERNAL METAL LINING DESIGN++
- Circular Cabinet Design of continuous curvature suppresses flow corner singularities and eddies for higher energy efficiency++
- Insulated double walls in cylindrical and rectangular cabinets reduce energy Losses; sound power level and air leakage rate to ASHRAE standards.
- Inner sheet metal wall lining prevents airflow contacts with fiberglass insulation and dust particles for high Indoor Air Quality (IAQ)
- Designed specifically for high IAQ requirements in Homes, Schools, Healthcare facilities and Government/Public Offices.
- Equipped with Thermostatic Expansion Valve (TXV), Transformer, Time-delay; and direct drive programmable ECM motors for efficient operation
- Carefully rated heating elements for comfortable room temperatures
- Direct Expansion coils are designed with rifled tubing, louvered surface and rippled Edge aluminum fins for high energy efficiency
- Powder-coated pre-painted cabinet for rust-free appearance
- All copper joints are sweat connections to prevent refrigerant leaks
- Several electrical knockouts provided for direct access to power supply and low-voltage lines
- Mounting tracks provide easy installation and removal of evaporator coil
- Multi-position cabinet installation with support brackets for circular cabinet
- Removable sliding filter-racks for easy access for installation and removal of air filters
- Capacity and Efficiency based designs
- Meet AHRI and ASHRAE Standards and conform to ETL Testing Standards
