Anupam Electroheat’s Micro Tubular Coil Heater is a small, linear heating element that can be formed into different shapes and configurations. Also known as a Hot Runner Heater for its extensive use in Hot Runner Systems, the Micro Tubular Coil Heater is a high performance heater which allows high wattage in a limited space. The ability to shape a Hot Runner Heater when cold enables to heat up parts with different shapes. During coiling, the gap between turns of coil can be modified to compensate for the heat losses at each end of the coil or to insert the heating element into slots. Micro Tubular Coil Heater has a larger cross-sectional area and is thus capable of greater power than Micro Coil Heaters. For this reason the Hot Runner Heater is used in hot runners with adequate space and where high heat densities are required. Micro Tubular Coil Heater can accommodate type “J” or “K” thermocouple sensors. Since the measurement point of a built-in thermocouple is situated in the Hot Runner Heater and never where the heat is actually required, our Micro Tubular Coil Heater with a thermocouple makes particular sense where the application allows the use of larger processing temperature or where the installation location or the design requires protection against overheating. The standard connection for our Micro Tubular Coil Heater is a 1000 mm PTFE-insulated lead wire with Fiberglass sleeve with protective earth conductor lead.

Micro Coil Heater is a high performance heater for smaller diameter Nozzles and Nozzle Tips that can also be formed in grooves to create three dimensional heating applications. Owing to their small cross-sectional dimensions, Micro Coil Heater is most often connected at both ends and do not permit the integration of a thermocouple. The Controlled atmosphere annealing at the end of the manufacturing process allows the bending of this type of Micro Coil Heater into very complex shapes with extremely narrow bending radius. Passing through this process helps the Micro Coil Heater have total flexibility in the distribution of heating density on the whole surface of the heated body. 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 Micro Coil Heater is formed into a hairpin shape and wound in a parallel format. Our unformed Micro Coil Heater is also supplied in the hairpin bend shape as standard. Micro Coil Heater solves heating problems, where space is limited.

Mini Coil Heater is manufactured in Two Standard Round Diameters of 1.5mm and 1.8mm. The Mini Coil Heater is swaged and compacted to these diameters and fitted into special clamps to tighten over circular parts for heating purpose. Sheath material available is Chrome Nickel Steel. The Flat diameter of 1.3 mm x 2.3 mm can also be made which is tightly coiled on a heat-conducting precision tube and encapsulated and thermically insulated by an outer lathing part. The Mini Coil Heater clamping styles is designed to save hours of downtime in moulds. The Mini Coil Heater is equipped with special cover for easy fitment over circular parts.

Characteristics of our Inner Outer Sleeve Coil Heaters are easy mounting and variable heat distribution. Because of its direct touch and tolerance fit, the Inner Outer Sleeve Coil Heaters allow a very good heat transmission to the nozzle. The Coil Heating Element when used with the Inner & Outer Sleeves increases the maximum surface load capacity. In all our Inner Outer Sleeve Coil Heaters, the assembly of a thermocouple is possible to carry out a controlled temperature measurement. The Inner Outer Sleeve Coil Heaters are recommended for bigger diameters and power. The Inner and Outer Sleeves protect the Coil Heaters from Mechanical Damages. The Inner & Outer Sleeves can be delivered for a lot of Coil Heating Element dimensions. The Coil Heating Element is available with an option of using either Brass or Stainless Steel sleeves. The Coil Heating Element can be encased only on outer surface or both on the Outer & Inner Surfaces for more protection from Mechanical Damages.  

Anupam Electroheat’s Low & Medium Density Cartridge Heater is developed for heating applications not requiring high watt densities and sheath temperatures not exceeding 300°C. These Cartridge Heating Elements are designed in maximum watt densities of 30 to 45 watts per square inch depending on applications. Such a Cartridge Heating Elements of various sheath diameters can be used in any assembly, equipment or machine. The Low & Medium Density Cartridge Heater can be absolutely customized to suit customer’s needs. Such Cartridge Heating Elements can be an economical option for customers not requiring high process temperatures. Cartridge Heating Elements are designed & calibrated perfectly to ensure that optimum conductivity between the resistance coil and the Cartridge Heater is achieved. The Low & Medium Density Cartridge Heater design consists of a helically wound resistance coil made from nickel-chrome wire, evenly stretched and strung through holes in a round ceramic insulator. The element assembly is inserted into a Chrome Nickel Steel. This alloy provides the best combination of physical strength and resistance to heat oxidation up to 450°C. Specially selected grain size and high purity magnesium oxide is used to fill all remaining space inside the ceramic insulator to increase thermal conductivity, dielectric strength, and provide longer operating life of the Cartridge Heater.
