V-Belts: Emerson, Browning Industrial Automation
Browning has introduced its latest notched V-belts with the benefits of EPDM heat-resistance and durability. The company has added an expanded temperature rating of -60°F to 250°F to some of the most commonly used V-belt cross sections in the HVAC industry: AX, BX, CX, 3VX, 5VX, and 8VX Gripnotch belts. Company officials said the EPDM formulated belts have a 110ºF (43ºC) higher heat tolerance than industry-standard polychloroprene belts, making them ideal for rooftop blower units, commercial kitchen, or industrial process exhaust systems.
EPDM (ethylene propylene diene monomer) is a synthetic rubber compound formulated for strength, flexibility and resistance to heat, decay, ozone, oxidation, and humidity. Browning's notched V-belt styles are designed to improve drive efficiency 2% to 3% over wrapped style V-belts, saving about $300 per year on a 20-hp/15-kW drive at $0.12/kWh.
