• Condensers and evaporators

Century’s high-efficiency ECM (electronically commutated motors) and PSC (permanent split capacitor) motors are optimized to reduce energy consumption, making them a top choice for HVAC manufacturers and contractors. The quiet operation, long service life, and automatic overload protection built into many models help ensure worry-free heating and cooling.

For variable air volume (VAV) systems and energy-compliant upgrades, Century’s variable speed motors like Genteq Evergreen (a Regal brand) integrate seamlessly with modern HVAC technologies. With options for open and enclosed enclosures and direct OEM replacements, Century motors are a go-to solution for both new installs and retrofits.

🐄 Agricultural Equipment

Century’s farm duty single phase motors are engineered to thrive in rugged agricultural settings, where exposure to dust, humidity, and fluctuating temperatures is routine. These motors are ideal for:

• Crop conveyors and augers
• Barn exhaust and ventilation fans
• Irrigation pumps
• Grain dryers and silo unloaders

Equipped with TEFC (Totally Enclosed Fan Cooled) enclosures, high starting torque, and weather-resistant coatings, Century farm duty motors are designed for maximum durability and minimal downtime. They feature corrosion-resistant materials and double-sealed ball bearings, making them reliable even in the most demanding field conditions.

Century motors meet or exceed NEMA service factors, ensuring they can handle continuous heavy-duty operation. Whether you're running a dairy farm or a commercial greenhouse, Century motors provide the power and reliability needed for uninterrupted productivity.

🏊 Pool & Spa Pumps

Century is a dominant force in the pool and spa motor industry, trusted by pool professionals and OEMs alike. Their motors power pumps from major brands like Pentair, Hayward, Sta-Rite, and Waterway, making them widely compatible and easily serviceable.

Product offerings include:

• Single-speed motors for standard filtration
• Dual-speed motors for energy-efficient cycling
• Variable speed motors like the VGreen® series for maximum energy savings and programmable performance

These motors are built for outdoor exposure, featuring sealed ball bearings, corrosion-resistant end bells, and integrated thermal protection. Many Century pool motors are UL-listed and designed for chlorinated and saltwater environments, ensuring long-lasting performance with minimal maintenance.

Their quiet operation and low energy draw meet growing consumer demand for eco-conscious pool equipment that complies with DOE Energy Efficiency Standards.
