HotCoils − Coil Heaters

HotCoils have a larger cross-sectional area and are thus capable of greater power than MicroCoils. For this reason they are used in hot runners with adequate space and where high heat densities are required. Owing to the large number of variants and for cost reasons, the sheath material for HotCoils is stainless steel - the standard for the market and thus also for Freek. HotCoils are large enough that thermocouples can be integrated into them. Our standard here is Type J (Fe-CuNi; red/blue), while Types J and K are also available conforming to the IEC and ANSI standards (see colour codes). Since the measurement point of a built-in temperature sensor is situated in the heater and never where the heat is actually required, a HotCoil with a thermocouple makes particular sense where the application allows the use of larger processing (temperature) windows or where the installation location or the design requires protection against overheating. The standard connection for our HotCoil heating elements is a 1000 mm PTFE-insulated lead wire with fibreglass sleeve and protective earth conductor.

HotCoil Variants

MultiPower HotCoils

Despite their comparatively large cross-sectional areas, HotCoils can also be successfully used in miniaturisation. They offer ample space for a heating coil wound out and back plus an integrated thermocouple. As a special design, meanwhile, we also offer HotCoils with two separate heating zones, that is, two separate heating coils. These can be controlled independently of one another (MultiPower option) or connected in parallel (fail-safe option).

HotCoil Cartridge

For many precision applications, even the smallest conventional cartridge heater dimensions are still too big. Particularly where temperature-regulated process control must take place at the same time, yet due to lack of space can only be achieved via the heater, low-voltage HotCoil-based heating cartridges are a trusted alternative. Here Freek has built up an extensive body of practical knowledge through successfully resolving a large number of special applications.
