Description

In the same power condition, finned tubular heater for air cooler has fast heating efficient,long life working advantage.In the limited heating space ,it can contain 2-3 times power ,lowering the heating volume and save the customers' cost.

Tube bundle is the main part of the air cooler, which is composed of finned tube, tube box and frame, and is an independent structural whole.

The advantage of the finned tubular heater for air cooler has the following advantage:

1. Strong heat transfer capacity.According to the principle of enhanced heat transfer, fins are added on the surface of the tube with a small heat transfer coefficient to increase the heat transfer area, promote turbulence and improve the heat transfer coefficient. The test shows that the heat transfer area can be increased by 2~10 times and the heat transfer coefficient can be increased by 1~2 times.

2.Compact structure ,due to the increase of heat transfer surface per unit volume, heat transfer capacity, the same heat load compared with the light tube, it has less tubes,shell diameter or decrease the height.

3.More effective and rational use of materials • Not only because of the compact structure to reduce the amount of materials, but also for heat transfer and process requirements can be flexible selection of materials. Examples include Mosaic or welded finned tubes made of different materials.

Finned tubular heater for air coolers bring a series of advantages as below:

Save industrial water consumption and avoid environmental pollution caused by industrial water discharge;

Low scale and corrosion of air;

The maintenance cost of air cooling systems is only 20-30% of that of water cooling systems

It is built-in overtemperature protection device, if heating temperature is higher than 120℃, there must be a heat insulation or heat dissipation zone between the junction box and the heater.They are widely used in application which require forced convective heating of air or gases at low to medium temperatures.

They are more efficient than tubular heaters since fins greatly increase surface area.permit faster rate of heat transfer to air,and thus higher wattage levels are achievable in the same flow area.

Electric Finned Air Tubular Heating Element has been developed to satisfy the need of temperature controlled air or gas flows which is present in several industrial processes. It is also suitable to keep a closed ambient at a specified temperature.They are designed to be inserted into ventilation ducts or air conditioning plants and are directly flown by the process air or gas.

Electric Finned Air Tubular Heating Element is an electric heating element that maximizes heat intensity and transfer effectively in an area. Slant fin heating elements is an excellent industrial heating product that can be installed on the surface of the heater. Mounting holes are useful to mount the heaters securely on the wall housing with terminal extending from the sheath for easy electrical connections.
