Nexthermal Hotlock Coil Heater

Introducing the next generation Hotlock mini coil heater. The new design utilizes a positive locking positioning ring and machined components to reduce manufacturing complexity. Installation is easy with a twist of the end cap ring the heater is secured into position on the nozzle, and with the integrated thermocouple slot located under the cap the thermocouple is precisely located. No tools are required for installation or removal.
 
Nexthermal’s proven mini coil technology is at the heart of the Hotlock. This Hotlock design protects the mini coil heater with an inside, outside stainless sheath and enclosed end rings for superior durability. Standard IDs of 0.75-in. and 0.87-in. will be stocked with standard lengths, voltage, and wattages. Custom build to order Hotlocks can be manufactured in 2 weeks or less. Nexthermal will develop custom inside diameter Hotlocks for major OEM opportunities.
