Company
Precision-engineered thermal solutions.
HEAT-ONN is a manufacturer and engineering partner for industrial heating elements and temperature sensors, headquartered in Peenya, Bangalore.
Company introduction
Established with a foundation of technical expertise dating back to 2005 (originally founded as Sun Electricals and formally structured in 2016), HEAT-ONN is a trusted manufacturer and engineering partner for industrial heating elements and temperature sensors.
Headquartered in the major industrial hub of Peenya, Bangalore, we specialize in delivering high-performance, precision-engineered thermal solutions designed for original equipment manufacturers (OEMs) and demanding industrial applications worldwide.
Our mission
To supply heating elements that hold their specification in service, and to make the engineering behind them easy for a customer to check.

Made & tested in-house
Manufacturing Infrastructure & Specialized Facilities
Unlike traditional single-roof setups that risk cross-contamination or production bottlenecks, HEAT-ONN operates four distinct, purpose-built units across Bangalore.
This strategic segmentation allows us to maintain strict quality control, specialized machinery, and dedicated engineering workflows for each product category.
Unit 1
Cartridge & Thermocouple Manufacturing Unit
Dedicated strictly to the production of high-density cartridge heaters and precision temperature sensors (Thermocouples and RTD probes), ensuring high electrical insulation standards and exact sensor calibration.
Unit 2
Ceramic & Mica Heater Manufacturing Unit
Equipped for specialized winding, insulation assembly, and stainless-steel cladding required for high-efficiency ceramic and mica band, strip, and nozzle heaters.
Unit 3
Tubular Heater Manufacturing Unit
Optimized for heavy-duty operations, including element bending, swaging, and automated welding/brazing for industrial immersion, flanged, and finned air tubular heaters.
Unit 4
Corporate & Commercial Office
Houses our management, customer support, custom engineering design teams, and logistics coordination—separating administrative workflows from the factory floor to ensure rapid communication and project turnaround for our clients.
Quality Assurance & Compliance
At HEAT-ONN, reliability is engineered into every product. We adhere to rigorous global quality frameworks to ensure our components seamlessly integrate into critical machinery:
ISO 9001:2015 Certified
Our quality management systems govern everything from raw material sourcing and in-process dielectric testing to final wattage and resistance verification.
CE Standard Compliant
Manufactured in alignment with European safety, health, and environmental protection requirements, making our catalog viable for global machinery exports.
Core Industries We Serve
Our specialized manufacturing units enable us to support diverse industry verticals that demand continuous thermal stability and precision control:
Plastic Processing, Extrusion, and Injection Molding Machinery
Packaging Equipment and Sealing Systems
Medical and Laboratory Devices
Food Processing and Industrial Ovens
Special Purpose Machines (SPMs) and Heavy Process Engineering
What we do in-house
Element Winding
Resistance wire wound and tensioned to the calculated wattage for each build.
Sheath Forming
Tube drawing, swaging and bending to the dimensions the assembly requires.
Insulation & Compaction
Magnesium oxide and mica insulation compacted for dielectric strength and heat transfer.
Assembly & Termination
Terminals, leads, braids, conduits and thermocouples fitted to specification.
Electrical Testing
Resistance, insulation resistance and continuity checked on every element.
Replacement & Retrofit
Existing or obsolete elements reverse-engineered from a sample.
From enquiry to dispatch
01
Requirement Review
Operating temperature, medium, dimensions, wattage and voltage are confirmed before design.
02
Design & Sample
A drawing or sample is prepared and agreed so fit and termination are settled early.
03
Manufacture
Elements are wound, formed, insulated and assembled against the approved specification.
04
Testing & Dispatch
Each element is electrically tested and visually inspected before packing.
How we work
Application First
Specification starts with the process, not a catalogue page.
Honest Engineering
Clear answers on what an element will and will not do in service.
Consistency
Repeat orders built to the same agreed specification.
Direct Support
Speak to the people who make the heaters, not a call centre.
