The 495017214-2150 Polyimide Heater Jacket for 1.7 inch diameter vacuum tubing straight sections is 14.0 inches long and operates at 200-240 VAC. Series 49UL polyimide heater jackets feature a new advanced Series 49UL temperature controller and intuitive user interface system that enables quick and easy system access and diagnostics. Polyimide heaters can be used in all critical applications where minimal outgassing, ultra-low particle generation, elevated temperatures up to 200°C, and ease of installation are required. These patented heaters are constructed with fully squared ends and a form fit shape to maximize thermal efficiency and temperature uniformity, minimizing thermal losses and power consumption. Polyimide heaters enable lower cost heating compared to other solutions. The new advanced Series 49UL controller technology allows for more versatility providing maximum flexibility in system configuration. This unique controller integrates a temperature process controller, a high-low temperature alert, power switching with a safety high limit, and detailed diagnostics. The user friendly Series 49UL User Interface System allows quick and easy set up and operation with a downloadable software application that provides full access to all functions of the Series 49UL heater control system. The application provides intuitive system control set up, monitoring, diagnostics and parameter adjustments creating a user friendly experience. The User Interface System adjusts variables such as temperature set points, upper and lower temperature threshold alarms, control parameters, and heater identification as well as advanced parameter setting for users to fine-tune the Series 49UL heater network. The user interface app contains a sequential auto-addressing function which automatically sets the address of the heater controllers in a network, ensuring accurate communication and identification of each connected heater.
