Tubular Heaters
Deep Heaters is a trusted tubular heater manufacturer in India, delivering reliable and energy-efficient heating solutions for diverse industrial applications.
Tubular Heater for Industrial Heating Applications
Deep Heaters manufactures precision-built tubular heaters designed for direct air, liquid, and surface heating in industrial systems. Each industrial tubular heater is developed to handle continuous production conditions while maintaining stable and controlled temperatures.
The heaters are commonly utilized in the ovens, dryers, water heating systems, oil tanks, HVAC devices, packaging machines, food processing facilities, and chemical facilities. They are also versatile in construction to enable them to be shaped into straight or customized shapes to fit machine layouts and machine space demands.
Being a well-established tubular heater supplier, Deep Heaters assists industries where heating performance must be consistent to maintain continuous product flow, product quality, and productivity.
What Is a Tubular Heater?
A tubular heater refers to an electric tubular heater which is developed to change electrical energy into heat and transmit it effectively to air, liquids, or metals.
The inner heating coil is a nickel-chromium resistance wire that is usually placed in the middle of a metallic sheath. Highly compacted magnesium oxide powder is placed between the coil and sheath space to offer good insulation of electricity and good thermal conductivity properties.
This construction provides a safe operation, rapid heat transfer, and mechanical stability in the medium- and high-temperature industrial use.

How Does a Tubular Heater Work?
Tubular heaters are based on the theory of electrical resistance heating, in which electrical energy is changed to thermal energy and applied to necessary material.
1
Electrical Current Flow
When power is supplied, current flows through the internal resistance wire positioned at the center of the heater.
2
Heat Generation
The resistance wire generates heat due to electrical resistance, quickly reaching the designed operating temperature.
3
Insulated Heat Transfer
The electrically insulating and highly heat-conductive compacted magnesium oxide powder surrounding the coil conducts the heat to the outer metal sheath.
4
Heat Delivery to Application Surface
The outer sheath conducts the heat generated to air, liquid, or point of contact to maintain constant and controlled temperature performance.
Installation and Maintenance Guidelines
Correct installation and periodic inspection help maintain heating efficiency and extend operational life.
- Select proper watt density for the application
- Ensure adequate immersion level in liquid heating
- Avoid dry operation in immersion systems
- Secure mounting to minimize vibration stress
- Inspect terminals and wiring connections regularly
- Remove scale buildup in water heating applications
