Different Pneumatic Control Systems Used in Heating Systems

By Todd Smith


The pneumatic control systems are a vital piece of a considerable number of typically used instruments and systems. As well as the enormous setup employed in construction and engineering work, a number of regular home appliances also run through the pneumatic solution. The heating systems running through pneumatic controls are operated through compressed air. Routinely, the air is compressed at 15 to 20 pounds per square inch gauge (psig).

A user can easily install and operate the hydraulic control system by knowing the different parts and modulating functions. Irrespective of the design and use of the setup, pneumatic tools are required to be supplied with compressed air. The pneumatic solution employed in heating systems should be supplied with clean and dry air in a compressed state.

So that you can find these heating systems designed with a compressor and tank. The dedicated compressor supplies compressed air, whereas the tank assists in keeping the air filtered, clean, and dry. However, the pneumatic controls utilized in heating systems differ from one model to another. Some of these systems are designed with direct-acting pneumatic controls, whereas others use reverse acting pneumatic controls.

The heating system using direct-acting pneumatic controls increase the output air pressure by intensifying the level of pressure or temperature. On the other hand, the reverse-acting pneumatic control can lower the output air pressure notwithstanding an increase in the pressure or temperature level. So you've got to test your heating system to identify the sort of pneumatic control system utilized by it.

But almost all of the latest models of heating systems are designed with the bleed-type control that can be either direct or reverse pneumatic control. These control systems typically use an adaptable restrictor to control and restrict the flow of compressed air into a nozzle. Based totally on the force applied to the nozzle thru a hinged flap, the output line also varies.
