Besides their own clamp-band designs Freek also manufactures original Rosemount clamp-bands that can be used as "Husky-replacement heaters" (see spare part cross-reference list). For example the two screw clamp band (FB) and the axial clamp band (FE). Freek has all the various industry standards for clamp-band nozzle heaters in Ø19,05 and Ø22,40 in their assortment, too. HotCoil minitubular heaters with clamp band are a highly demanded and very flexible clamping system, especially for heating larger nozzles and bushings with high power. The size-variable customizable clamp bands counteract the heating's thermal-related "lifting ambition" during heat-up and thus effectively prevent a possible critical overheating. For an even better protection all HotCoil heating elements can also be provided with an integrated thermocouple. As alternative to our standard clamping mechanism with welded clamping elements a space-saving lug clamping mechanism can be supplied.

We can offer flexible heating elements manufactured from three different insulation materials: silicone, polyimide (Kapton) or polyester. Each of these materials possess different properties which make them suitable for diverse applications. Silicone heaters can also be produced in very large sizes, whereas polyimide is significantly thinner and polyester unbeatable in price when it comes to high quantities. All three of them are bespoke products made according to your needs, so within the bounds of what is technically feasible you as the customer can determine almost every feature of your heater. This can include; voltage, wattage, dimensions, shape, sensors, leads, plus much more. Due to their low thermal mass flexible polymer insulated heaters distinguish themselves by a very short response time and excellent controllability.

Thermo Sensors are needed in any controlled heating process. For various applications different types of thermocouples are obtainable. Most common are thermocouples (TC) and resistance sensors (RS). Both types are available in the same executions as a matter of princible. For non-contact measuring infrared sensors are the rights choice, either in stationary executions or as portable measuring instrument.
