Explosion-proof Heater

This is an explosion-proof electric heater. I have provided its working principle, structural composition, technical specifications, advantages, and images below for your reference.

Working Principle

The core working principle of the air heater is the energy conversion of “electric energy → thermal energy+wind energy”, and the specific process is divided into two steps:

• Heating link: The internal electric heating elements (such as PTC ceramics and resistance wires) generate heat after being electrified, which converts electric energy into heat energy and raises the ambient air temperature.

• Air supply link: The built-in fan operates to push the cold air to flow through the heating element to be heated, and then blow the hot air to the external space through the air outlet to realize rapid temperature rise.

Structural Composition

• Three-dimensional box: the outer color square shell is the core accommodation structure of the equipment, and the core components such as motor and wind wheel are usually installed inside.

• Control panel/wiring area: the red wiring terminal+switch area on the side of the box is used for power supply access and circuit control.

• Air outlet/air inlet: a cylindrical structure with a red border on the right side, which is a channel for airflow transportation.

• Warning sign: yellow label on the top of the box, which generally indicates safety precautions (such as power consumption and operation warning).

• Connecting wire: white cable at the bottom of the box, which is used to connect the equipment with external power supply/control system.

Introduction to Industrial Hot Air Blowers

Components：

• Heating module: Built-in high-power heating elements (usually PTC ceramics or metal heating tubes) are the core components to realize rapid temperature rise.

• Air supply system: equipped with a fan, which can quickly spread the heated hot air into the space.

• Control unit: including gear adjustment knob (supporting multi-gear power switching) and power switch, some models have temperature control function.

• The fuselage structure：
  Shell: made of high-temperature resistant and insulating plastic or metal;
  Protective parts: grid-like grille at the air outlet (preventing foreign bodies from entering+preventing scalding);
  Portable parts: top handle+bottom bracket, easy to move and place.

Product Specifications：

Model Number：ST

Heating Power：3000W/5000W

Rated Voltage：220V

Frequency：50HZ

Colour：Black / Military Green + Yellow

Product Advantages

• Built-in heating chip, stable performance, using energy-efficient PTC heater, quick heating for heating.

• The number of gears can be adjusted, that is, it is hot when it is opened, mild and not harmful to the eyes, and the temperature rises rapidly.

• Fully enclosed motor, powerful and stable operation, longer service life of all-copper coil.

• Stable site support, more convenient and safe

• Thickened shell, the surface is made of environmentally-friendly high-temperature resistant powder, and the heat-resistant and insulating layer is arranged in the middle.

Energy-saving Mechanical Electric Heater

This is a high-power, energy-saving industrial electric heater with mechanical controls. It features adjustable settings, a pure copper motor, and a stainless steel heating element, offering intelligent constant-temperature performance. The specifications and images are provided below for your reference.

Product Structure

• The unit is made of metal, with an eco-friendly, high-temperature-resistant powder coating on the surface for heat resistance and insulation, and features an insulation layer in the middle.

• It utilizes a stainless steel finned heating element. Made of stainless steel material, it is energy-saving and electricity-efficient, features rapid heat conduction, and offers a longer service life.

• At its core is a large-diameter centrifugal fan on the front. The impeller and diffuser design rapidly push heat over long distances, enabling hot air circulation in large areas. The protective guard outside the fan prevents foreign objects from entering, ensuring safe operation.

• The control buttons are located on the side of the unit, used to adjust the gear settings, set the temperature, control the fan speed, and power the machine on/off. Some models are also equipped with a temperature sensor to achieve constant temperature control.

• Equipped with universal casters on the bottom, the unit can be moved flexibly to adapt to heating and drying needs in different work areas. The brake system can secure the device in place to prevent sliding.
