The HCC controller line is designed to power large scale equipment up to 100 liter heating mantels. Built with the same uncompromised commitment to safety as our Model 270, the HCC series is available in 3 models for 120 or 230 volt operations. This controller also incorporates a 100 hour timer to turn heating OFF (or ON) when the time expires. The HCC controller line is designed for easy customization to meet unique research or additional safety needs.
