HIGH COUNTRY TEK – Hybrid Fan System Controller, EMC-6 & EMC-6L

Increase fuel economy and reduce emissions with High Country Tek's EMC-6, the industry's first variable speed hybrid fan controller capable of simultaneously controlling variable speed electric and hydraulic fans, water pumps, and engine accessories. Maximize engine performance by reducing the load on the engine and controlling the temperature regulated systems as needed.

The automotive industry worldwide is investing to find the most effective means of improving fuel efficiency and reducing emissions while cutting costs. The EMC-6 is the simplest solution that provides immediate results by providing extensive input/output selection with easy to use complete customizable configuration software. This enables automotive/mobile design engineers and manufacturers the flexibility of reducing weight, combining electronic control systems and maximizing engine performance. A positive change for the environment while realizing significant financial savings.
