Designed with quality and performance in mind, this High Amperage Dual Fan Controller breaks new ground in the industry of electric fan controllers. 100 per cent USA made, a bulletproof design, 35 amp per fan amperage rating, adjustability from 150 degree-240 degree F, and a die cast bright finish aluminum cap, come together to make this dual fan controller stand out from the crowd. It's capable of controlling two separate 35 amp fans at different turn-on temperatures, with only a single probe. The first electric fan will be activated at the temperature set by the user followed by the second electric fan when the temperature becomes 10 degree F warmer. Each electric fan will turn off at 10 degree F below its turn-on temperature. Kit comes complete with wiring harness, fusible link, all necessary electrical connectors and 3/8 inch NPT thread-in probe.
