For more than 40 years, Webex has been the industry’s first choice in maintaining consistent and cost-effective temperature management with our Precision Engineered Heat Transfer and Chill Rolls.
Webex Engineers rely upon industry experience and a proprietary analysis process to predict exactly what the heat transfer results will be prior to manufacturing, to within ±1º F (0.5º C) across the face of the roll. We also specialize in rolls with ultra-tight tolerances, special plating and finishing.
To meet your exact application parameters, every Webex Heat Transfer and Chill Roll is designed for optimal balance between heat transfer, minimal pressure drop inside the roll, correct fluid velocity and minimum temperature rise across the roll face. Whatever roll size or specification you need, Webex is the proven source for heat transfer roll performance.
