Coil Heater Manufacturers in Pune

Coil Heater in Pune - Surya Industrial Products

Surya Industrial Products is an Ultimate Coil Heater Manufacturers in Pune, Suppliers and Dealers in Pune. A coil heater is a form of industrial heating element that is used to supply high temperatures with a small form factor. It consists of a heating component (resistance heater, typically nickel-chromium alloy) held inside an enclosure (usually stainless steel or nickel alloy) and sealed with a high-purity substance such as magnesium oxide (MgO). Such heaters are sometimes coiled like coils or helices to encircle or stick onto the objects that need heating.

What is a Coil Heater?

Coil Heater Manufacturers in Pune are a kind of heating element used in industries, which is made in a compact form to offer high temperatures efficiently. It is usually a resistance wire (such as nickel-chromium) wrapped into a coil and surrounded by a metal sheath (usually stainless steel) stuffed with an insulating material such as magnesium oxide (MgO). The coil may be coiled into cross-sectional shapes to either wrap around or be put inside equipment that needs to be heated.

Types of Coil Heater

Being as well-established Coil Heater Suppliers in Pun, these are the types of Coil Heater as per requirement which are given below :

Based on shape

  • Round Coil Heater: It is a common type of coil heater that has a round material with a cross-section that can be used in a wide range of heating purposes.
  • Flat Coil Heater: Shaped in a flat form, and is easy to install in tight areas and is commonly applied in injection molding equipment.
  • Square Coil Heater: Square in cross section and are applied in situations where a particular shape or fit is necessary.

According to the constructions and functionality

  • Micro Coil Heater: This is a compact and versatile type of heater that is applied in such processes as hot runner nozzles and other industrial heating processes.
  • Micro Tubular Coil Heater: Like micro coils except that the cross-sectional area is larger, hence this makes it possible to have high power density and heat output.
  • Hot Runner Coil Heater: This is meant to be used in hot runners used in both plastic and metal injection molding machines.
  • Maxi Coil Heater: This is a heavier, larger heater with an increased wattage capacity and is used in high-performance applications in large molding machines.
  • Formable Coil Heater: Industrial coil heater manufacturer is a flexible heater, which can bend or shape it to fit the challenging or unusual geometry without breaking the internal heating components.
  • Star-Wound Coil Heater: The design has offset coils that apply to pipes and ducts. Turbulent flow is generated by the offset, and this enhances heat transfer.
  • Straight/Pre-formed Heater: Coil Heater Suppliers are straight, straight and ready-made heating elements whose ends can be bent in place to fit into equipment, or the elements can be utilized where a coil is unnecessary.
