MILFORD, Indiana, U.S.A. — Chore-Time has introduced direct-drive models of its innovative ENDURA® Fan. The new 57-inch (145-cm) direct-drive fans meet grower requests for low maintenance, while maximizing energy efficiency through variable-speed capabilities.

Low Maintenance

With no belts, pulleys or bearings, the direct-drive motor eliminates the need for regular greasing, as well as other common maintenance needs on ventilation systems. For further reliability, the materials used in the proven ENDURA Fan design were strategically selected to provide corrosion resistance, high strength and maximum durability in both extreme high and extreme low temperatures.

Superior Efficiency

The direct-drive ENDURA Fans efficiently produce one of the highest airflow ratings in the industry. Variable speed functionality allows growers to achieve further energy savings by slowing the fan whenever the air flow requirements allow. Fan speed is controlled automatically by a CHORE-TRONICS® 3 Controller, in combination with a variable frequency drive.

Even greater efficiency comes from the use of Chore-Time’s HYFLO® Shutters featured on the ENDURA Fans. HYFLO Shutters do not suffer the typical 12- to 15-percent loss of efficiency and air speed typical of dirty louver-style shutters, so air speed is maintained to the end of the flock, when it is needed most. HYFLO Shutters improve fan performance by minimizing obstructions during operation. A cable attachment helps maximize efficiency by allowing the HYFLO Doors to float left or right together.

Additional Details

Other features of the direct-drive ENDURA Fans include a black, high-density polyethylene cone for light control and a long glass fiber composite shroud and HYFLO doors for durability. The units are engineered to have a slight downward tilt, making them self-draining.

The new fans are available with a standard mount and can be installed 60 inches (152.4 cm) on center over 56.5-inch (143.5-cm) framed openings. They can also be retrofitted over openings for many 48- through 54-inch (121.9- through 137.2-cm) fans.
