Finned Tube Heater

Finned Tube Heater

Finned Tube Heater.A versatile, lightweight heater with excellent heat transfer.

In the finned tube heater, strip-shaped fins are wrapped in a spiral around the surface of steel pipes to enlarge the heat dissipation surface area, and these components are enclosed by a casing. A heating medium such as steam, oil or hot water is used.
Low pressure, medium pressure and high pressure types of finned tube heater are available, which differ according to the steam pressure that is used.
Combination in parallel or series is possible according to the airflow volume and required heat amount. This device can also be used as a cooler when cold water is used as the heating medium.

Features

1. Excellent heat transfer enables a compact device design
2. Materials can be selected according to the specifications
3. Heaters can be combined according to the specifications
4. A combination type, therefore replacement of individual sections is possible
5. An ink line method is used, ensuring high heat transfer efficiency
6. Combinations can be selected according to the objective, from low pressure to high pressure
7. Lightweight, sturdy and easy to handle

Applications

1. Heat source heater for a dryer
2. Heater for waste heat recovery
3. Air heater for factories, etc.
4. Cooler for cooling

Models/Specifications

73A Type. Through-flow area (m2/unit). Heat transfer area (AH) (m2/unit).

73B Type. Through-flow area (m2/unit). Heat transfer area (AH) (m2/unit).
