Especially for high-cavity PET plastic injection moulding there are various industry standards of clamp-band nozzle heaters available. Most common are the Axial Clamp-Band Heater and the Two-screw Clamp-Band Heater. Our HotCoil cable heaters with clamp band represent 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.

Our Locking System provides a quick, easy and reliable clamping of the heating element on the nozzle to be heated. It facilitates an effective heat transfer, as the inside sheath is pressed to the nozzle with a high level of precision creating an interference fit. Due to the method of construction of the lock, installation is possible in the restrictive space of small cavities. The lock can be operated quickly and efficiently with simple readily available tools.

Besides its own systems Freek also manufactures original Rosemount-systems that can also be used as "Husky-replacement heater" (see spare part cross-reference list). For example the two screw clamp band (FB) and the axial clamp band (FE). Both systems can be supplied with MicroCoils in "Rosemount style" (Ø 1,4 mm) as well as MicroCoils in "Freek style" (1,3 x 2,3 mm).

Characteristics of our HotMicroCoils with reflection tube are easy mounting and variable heat distribution. Because of its direct touch and toleranced fit, the sleeve coil heater allows a very good heat transmission to the nozzle. In all our HotMicroCoil heaters with reflection sleeve the assembly of a thermocouple is possible and recommended for bigger diameters and power.

The Freek heat transfer nozzle heater type especially addresses manufacturers and users who operated their hotrunner nozzles with cast-in heaters in the past and would like to stick to their engineering know-how without paying the high price of this former heater design. The standard material of our patent pending Freek heat transfer alternative is brass, with or without coating, basically with a slit. Characteristics of our HotMicroCoil nozzle heaters sheathed by a reflection tube are easy mounting and variable heat distribution. Because of its direct touch and toleranced fit, the heater allows a very good heat transmission to the nozzle. In all our HotMicroCoils with reflection tube the assembly of a thermocouple is possible and recommended for bigger diameters and power. Also most common nozzle heater solutions are HotMicrocoil heating elements with clamp bands with diverse locking mechanisms.

Owing to their small cross-sectional dimensions, MicroCoils are most often connected at both ends and do not permit the addition of a thermocouple. We prefer to use nickel as the sheath material here because it combines the best thermal conduction properties, high corrosion resistance and excellent deformation properties. To ensure that the standard 1000 mm PTFE-insulated connection cable can be positioned at one end, despite the standard two-ended connection of the element, in most cases the MicroCoil is formed into a hairpin shape and wound/laid in a bifilar (parallel) format. Our unformed MicroCoils are also supplied in the hairpin bend shape as standard. round cross secitons:Ø1,3 mm, Ø1,8 mm flattened sections:1,0x1,6 mm, 1,3x2,3 mm

The Freek heat transfer nozzle heating system especially addresses manufacturers and users who operated their hotrunner nozzles with cast-in heaters in the past and would like to stick to their engineering know-how without paying the high price of this former heater design. The standard material of our Freek heat transfer nozzle heater alternative is brass, with or without coating, preferably with a slit. The slit allows the assembly of an external bendable thermocouple and facilitates the disassembly, e.g. in case of a revision and can be coiled over. This is not possible at competitor's nozzle heater solutions. Freek's tight coiling at the heater's ends provides a maximum possible power concentration (patented).

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. Industry standard 1:Ø19,05 x 25,40 mm (Ø 3/4" x 1") Industry standard 2:Ø19,05 x 30,50 mm (Ø 3/4" x 1,20") Industry standard 3:Ø22,23 x 30,50 mm (Ø 0,875" x 1,20" Industry standard 4:Ø22,40 x 30,50 mm Industry standard 5:Ø 22,55 x 30,50 mm

The Freek-MicroCoil 1.3 x 2.3 mm used in the "Brazed-Together" energy-saving nozzle heater is wound tightly onto a precision tube with good thermal conductivity and encapsulated and thermally insulated by means of an outer housing. For even more reliable heat transfer, the heater can optionally be vacuum brazed. The "Brazed Together" design combines many advantages: high accuracy, good heat conduction, high power density, mechanical stability and, last but not least, up to 20% higher energy efficiency. Freek is one of the technology leaders in the field of hot runner heating and supplies the who's who of the industry. Energy efficiency is one, if not the central innovation topic here. Manufacturers of high-cavity PET hotrunners and moulds in particular benefit from the BT nozzle heaters, and in several ways: because the less energy that is put into the system, the less energy has to be taken out on the cold side, the mould. This saves even more energy and shortens the cycle time.

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. round cross sections:Ø2,0, Ø3,0, Ø3,3, Ø4,0 mm rectangular sections:1,4x2,4, 1,8x3,2, 2,0x4,5, 2,2x4,2, 3,0x4,8, 4x6 mm square sections:3,0x3,0, 3,2x3,2 mm
