HOT AIR BLOWER SANGI ELECTRIC

SANGI ELECTRIC Hot Air Blower (Industrial Hot Air Blower)

SANGI ELECTRIC Hot Air Blower is an electric heater set for generating hot air in industrial applications, designed to be used together with a blower to allow air to flow through the heating components and deliver hot air to the required location.

Suitable for production processes requiring hot air, such as paint baking, film shrinking, and heating parts in industrial machinery. It is possible to select the electrical power and design the heater size to match the system requirements.

The structure is made from stainless steel, using a stainless steel finned heater as the heating element, which has fins to increase the surface area for heat transfer to the air, along with a flange for installation with the Blower.

The product supports custom production according to drawings or samples. The details of electrical power, voltage, flange size, and usage conditions must be defined and confirmed before production.

Principle of Operation of Hot Air Blower

The Hot Air Blower system uses the principle of converting electrical energy into heat through an electrical resistance component. The air from the blower flows through the heater assembly and receives heat from the surface of the stainless steel finned heater.

When the air is heated, its temperature increases before being sent to the usage location, such as the area for baking workpieces or parts of the machine that require hot air.

The performance of the system depends on the electrical power, air flow rate, incoming air temperature, heat transfer surface area, and installation conditions.

Stainless Steel Finned Heater Component

The heater assembly uses a Stainless Steel Finned Heater, which has fins to increase the surface area for heat transfer to the air, helping to make it suitable for use in systems with continuous air flow.

The design of the fins and the placement of the heater must be related to the air volume, electrical power, and target temperature, in order to prevent heat accumulation and reduce the impact on the lifespan of the heating element.

Structure and Installation with Blower

The heater structure is made of stainless steel and has a flange for installation with the Blower according to the catalog data. The size of the flange and the mounting style must be designed to match the actual air delivery equipment.

The static pressure and air volume of the Blower should be checked to ensure that the air can pass through the heater assembly sufficiently and not cause unsafe heat accumulation.

The product name Hot Air Blower does not confirm that the Blower Motor is included in the standard delivery set. Therefore, it is recommended to check the equipment list with the supplier before ordering.

Use in Paint Drying Applications

The Hot Air Blower can be adapted for use in appropriately designed paint drying systems by sending hot air through the workpiece to assist the drying process under specified temperature and time conditions.

The use must consider the type of paint, coating material, and risk from flammable vapors. It is not advisable to use a general-purpose electric heater in an environment with flammable vapors unless it has been specifically designed and certified for that environment.

Use with Shrink Film Processing

The hot air system can be used to heat shrink films designed to contract when heated. It is necessary to select the appropriate temperature, air volume, and contact time according to the type of film and product characteristics.

Proper control of hot air helps reduce the risk of uneven shrinking or damage to the packaging.

Design of Electrical Power and Air Volume

The selection of electrical power for the Hot Air Blower should be calculated based on the air volume, incoming air temperature, and desired outgoing air temperature, as well as evaluating the system's heat loss.

If the electrical power is too high compared to the air volume, it may cause the heating element to become abnormally hot. Conversely, if the electrical power is too low, it may not be able to achieve the target air temperature.

The Blower data, including air volume and static pressure, should be checked to ensure that the air delivery system and heater assembly work together appropriately.

Temperature Control and Protection Systems

The Hot Air Blower system should be used in conjunction with an appropriate Temperature Controller and temperature sensor to control the hot air temperature according to the production process requirements.

For systems at risk of heat accumulation, it is recommended to install an airflow interlock system and high-temperature shutdown devices, separate from the normal temperature control circuit.

Details of the control and protection devices included in the product set must be verified from the actual product catalog.
