FT4B Performance PREMIUM ENVIRONMENTALLY RESPONSIBLE AIR HANDLER/FAN COIL
Thermostatic Expansion Valve (TXV) designed to maximize performance with Puron® refrigerant
Energy Efficient Operation
Variable Speed Constant Airflow ECM (Electronically Commutating Motor) operates efficiently at all speeds
Maximizes efficiency of heating and cooling systems
Ultra low power consumption during fan only operation
Indoor Weather Control
Warm, comfortable heating air temperatures
Unmatched humidity control
Airflow and Sound Technology
Diffuser air discharge section for high airflow efficiency and quiet, smooth operation
High duct static capability
Design meets stringent regulations for cabinet air leakage of less than 2% when tested at 0.5 inches W.C., and cabinet air leakage less than 1.4% at 0.5 inches W.C. when tested in accordance with ASHRAE 193 standard.
Condensate Control and Disposal Technology
Minimal standing waterless microbial growth for improved IAQ and reduced condensate line clogging and related condensate leakage
Condensate fittings relocated away from turbulent airflow patterns at the blower entrance for improved condensate control performance
Overflow feature for slope coil units allows condensate to exit the unit without damage to product under clogged primary and secondary line conditions
Tested for condensate disposal at conditions much more severe than those required by AHRI
Primary and secondary drain connections to comply with HUD
All pans constructed of an injection molded glass-filled polycarbonate engineered resin material, with brass drain connections.
High density, super thick cabinetry insulation with vapor barrier
