Coiled heaters - Import export

In linguistic usage occasionally the terms coil heaters, nozzle heating elements, hot runner heating elements, cable nozzle heaters are used. Our HotMicroCoil heating elements can be used in a wide variety of applications. Their high level of plasticity ideally suits them to the heating of hot runner nozzles and for accurately heating the contours of three-dimensional surfaces. Many of our customers order HotMicroCoil elements in their unformed state of mineral insualted cable heaters and perform the subsequent shaping work themselves, while others commission us to shape and fit the heating cable elements. A large number of ready-to-fit heating solutions are available for plastic injection nozzles with clamping mechanisms, housing bezel, reflection tube or heat conduction sleeve.

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.

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 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.

CSN® EXPLOSIONPROOF SPACE HEATERS CSN® explosionproof space heaters are used for heating zone 1 and 2 hazardous areas. Standard devices are available in the common temperature classes T1 to T4; temperature classes T5 and T6 can be offered on request. The use of finned tubes for the CSN® explosionproof space heaters is the most economical solution for heat transfer in the field of electric heaters. By coiling corrugated helical fins on tubes of different alloys, we obtain extremely large tubes surfaces and, consequently, low temperatures on their surfaces. We use this interaction to produce explosionproof space heaters on a highquality level. CSN® explosionproof space heaters with coiled fins are intended for horizontal mounting and suitable for both wall and floor mounting (for permanent installation)

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).

Evaporation coils are available in many different lenghts, diameters, coil lenghts and coil pitches. These resistance heaters with their very high melting points will bring practically any metal to the boil. At the same time, their high corrosion resistance and outstanding material purity prevent any contamination of the substrate. The range includes evaporation coils made of the following materials: — Grain stabilized tungsten (WVM) for the evaporation of aluminum — Tantalum — Molybdenum — Molybdenum-lanthenum (ML) for particularly long service lives

Hot air fan heaters with water coil (20 to 106 kW) - ATR The hot air heaters with hot water coil are ideal for heating all types of commercial, industrial or agricultural premises where a flow of hot air is required to heat different areas of the premises to be heated. The hot water must be produced by a diesel, gas or biomass boiler. The hot water, by means of a circulation pump, passes through the interior of the heating coil of the air heater and the heat transfer is carried out by the air fan of the air heater. The fan can be axial or centrifugal, the axial type is used for direct dissolution and the centrifugal fan allows a network of ducts to be applied in addition to having a greater reach.

BIEGLO offers finished or semi-finished parts directly formed from polyimide powder with all the attributes of sintered PI. The advantage of direct formed parts are the lower costs as quantitiy is increasing. Due to almost zero percent waste during production it can be a more economic production method. Machined parts are widely used for small series high precision applications. Polyimide direct formed parts can be used in different applications: Automotive industry: racing engine fuel line. Jet engine: vane bushing or lock nut insert. Industrial machinery: hotrunner systems nozzles or plasma cutting torch as gas distributers or sealing components. Semicon HDPCVD Equipment: e.g. heater coil spacer. Life sciences: rotor seal or pneumatic surgical tool vane.
