Watlow's THERMASLEEVE™ Nozzle Heaters Create a Precise Temperature Profile for Your Hot Runner System

Watlow's new THERMASLEEVE™ nozzle heater with patented manufacturing technology allows hot runner manufacturers to utilize a heater with rapid thermal response packaged in a low physical profile with a precise fit to the nozzle. The self-clamping heater is easy to install and remove and supports commercially available thermocouples.

Rapid Thermal Response...

Watlow's THERMASLEEVE heaters are designed to have intimate contact with the entire surface of the nozzle. This intimate contact combined with lower heater mass contributes to rapid transfer of heat to and from the tip versus conventional heaters.

Precise Temperature Profile...

Watlow's exclusive technology allows hot runner manufacturers to create precise temperature profiles beyond the limits of conventional heaters.

Low Physical Profile...

The THERMASLEEVE hot runner nozzle heater is designed to have an extremely low profile. Wall thickness ranges from as little as 2.00 mm (0.08 in.) up to 2.80 mm (0.11 in.).

Precision Fit...

Watlow’s THERMASLEEVE heater has intimate contact with the nozzle body due to its self-clamping feature. No additional clamping device is needed.

Repeatability...

THERMASLEEVE heaters allow accurate temperature and customizable wattage distribution across all of the nozzles on a hot runner system.

Optional External Thermocouple...

The THERMASLEEVE heater can house an external thermocouple secured to the nozzle’s body. The heater is designed with a slot to accommodate commercially available, off-the-shelf, thermocouple wire.

Easy Installation and Removal...

Watlow’s new self-clamping THERMASLEEVE nozzle heater can be easily installed and removed from the nozzle with the installation and removal tool.
