Description

Explosion-proof heating element is mainly used for heating fluids (e.g. water, oil) and gases (e.g. air, nitrogen). By a multi-purpose construction concept there are many applications. There are several materials available, so the correct harmonisation on the medium to heat can be made.

They are widely used in air, water, oil, acid and alkaline liquids, and can be effectively adapted to various environments, such as air separation equipment, metallurgy, high temperature runners, medical equipment, environmental protection equipment, etc. Out of consideration for problem-free operation, there are several materials available, so the correct harmonisation on the medium to heat can be made.

Compared with ordinary electric heaters, explosion-proof heating element is safer because they have explosion-proof treatment, and thus are favored by many industries. However, they cannot be used in all environments. Due to the explosion-proof feature, there are certain requirements in terms of usage conditions and environments.

Operating conditions and environment for explosion-proof electric heaters:
1.The altitude does not exceed one thousand meters, and this requirement can be easily met.
2. The explosion-proof electric heater cannot be used in extremely humid environments. Therefore, the humidity level should not exceed 90%.
3. The environmental temperature must be between minus twenty degrees Celsius and fifty degrees Celsius.
4. In the usage environment, there must be no any conductive objects, explosive objects or corrosive substances around; otherwise, it will be extremely dangerous.

We make the most common grades of stainless and acid-resistant steel, as well as a wide selection of high-alloy steel for harsh environments, high temperatures, etc.Junction boxes for immersion heaters are available in a wide variety of materials and executions, both as finished standard cabinets and as special round or rectangular cabinets.

The flame-proof (d) enclosures have been designed for hazardous areas to protect the environment against gas-explosions, caused by sparking by electrical connections of the heating elements and control devices.The screwed types for dimensions up to 3".The terminal enclosures have a IP66 degree of protection.All heaters are standard internal wired on terminals.

Most of the explosion-proof heating element is manufactured by argon arc welding to connect the electric heating pipe to the flange for centralized heating. It can also use the form of a fastening device, so each electric heating pipe is welded with a fastener. Then lock the flange cover with a nut. The tubes and the fastener are welded by argon arc without leaking. Fastener seal adopts scientific technology.

Feature and advantage:

1. The explosion-proof heating element is mainly used for heating in open and closed solution tanks and circulation systems. It's surface power is large, and the surface load of air heating is 2 to 4 times.

2. Highly dense and compact. Because the whole is short and dense, it has good stability and no bracket is required for installation.

3. Most of the combined types use argon arc welding to connect the electric heating pipe to the flange, and also can use the form of a fastening device, so each electric heating pipe is welded with a fastener, and then the nut is locked with the flange cover. The firmware is argon arc welded and does not leak. Fastener seal adopts scientific technology, single replacement is extremely convenient, greatly saving future maintenance costs.

4. Select imported and domestic materials, scientific production technology, strict quality management to ensure the superior electrical performance of electric heating pipes.
