Rooftop Condenser Fan Motor

Heavy-duty, weather-protected electric motors engineered for rooftop HVAC units, commercial air-cooled chillers, and remote condensers operating under high ambient temperatures.

The Rooftop Condenser Fan Motor delivers continuous duty performance in outdoor packaged rooftop units and commercial refrigeration systems. Built with IP55 weather sealing, Class F insulation, and double-shielded ball bearings, this motor withstands direct sun exposure, high temperature extremes, and continuous moisture without thermal degradation. Designed to fit standard 48 and 56 frame mounting configurations, it provides reliable airflow for efficient heat rejection across commercial HVAC applications.

Weather-Sealed Enclosure: IP55 TEAO housing prevents rain, dust, and debris from entering internal windings.

High-Ambient Thermal Rating: Rated for continuous operation in ambient temperatures up to 60°C using Class F insulation with Class B temperature rise limits.

Precision Ball Bearings: Synthetic grease-filled double-shielded ball bearings handle vertical shaft-up or shaft-down axial loads.

Corrosion-Resistant Hardware: Cast iron end shields, zinc-plated fasteners, and epoxy-coated rotor surfaces resist atmospheric corrosion.

Low Noise Profile: Dynamically balanced rotor assembly minimizes structural vibration transmitted into rooftop ductwork.

Packaged Rooftop Units: Drives condenser heat rejection fans in single-zone and multi-zone rooftop commercial air conditioning systems.

Air-Cooled Liquid Chillers: Operates in multi-fan chiller arrays requiring constant airflow under fluctuating ambient outdoor conditions.

Commercial Refrigeration Condensers: Powers condenser fans on supermarket walk-in coolers, rack refrigeration systems, and cold storage units.

Remote Air-Cooled Condensers: Serves as the primary air-moving drive in split-system commercial air conditioning and industrial process cooling.

Shaft Specifications: Single or dual shaft extensions, flat section geometry, keyway dimensions, and stainless steel material selection for coastal marine locations.

Electrical Winding Modifications: Custom voltage taps, thermally protected automatic or manual reset options, and inverter-duty magnet wire.

Drain Plug & Sealing Options: Removable rubber drain plugs at both end shields accommodate vertical shaft-up, shaft-down, or horizontal mounting orientation.

Lead Wire Terminations: Customized lead lengths, protective conduit sleeves, quick-connect terminals, or IP67 water-tight junction boxes.

Prototyping & Technical Validation: Delivery of evaluation samples with dynamometer test reports, thermal rise data, and 2D/3D CAD models within 15 to 20 working days.

Tooling & Stamping Customization: In-house stator and rotor die fabrication for custom frame geometry and specialized mechanical fitment.

Automated Batch Manufacturing: CNC machining, automated coil winding lines, and computer-controlled varnish processes ensure unit-to-unit consistency.

Quality Inspection: Every production unit undergoes 100% testing for insulation surge withstand, no-load current, power input, vibration, and high-potential safety limits.
 

Extended Thermal Reserve: Built with Class F magnet wire and Class H varnish to ensure stable operation under roof surface temperatures exceeding 60°C.

Water Ingress Protection: Shaft water slingers, liquid gaskets, and multi-lip seals block rainwater migration along the shaft into the bearing cavity.

Certified Compliance: Manufactured under ISO 9001 quality management systems with products meeting CE, UL, and RoHS regulatory standards.

Production Flexibility: Production lines configured to accommodate low-volume specialized OEM runs as well as high-volume scheduled container shipments.
