Cleaning of larger heat exchangers
Cleaning of larger heat exchangers and condensers is often carried out using a pneumatic or hydrostatic method. Projectiles are shot through the tubes at low pressure. These are shot rapidly through the tubes, within a matter of seconds, regardless of the length of the tubes.
Pneumatic vs Hydrostatic
Both methods offer the same solution; shooting through special projectiles. However, there are a lot of differences between the systems themselves.
- Pneumatic. This is performed with the QS-300 Quick Shot. This is a gun that works 90% on compressed air and 10% on water. This allows it to build up pressure, in order to quickly blow the projectiles through. This method can only be used for the standard tube scrubbers and coil brushes.

- Hydrostatic. This is a 100% water driven system (BFP), which allows projectiles to be shot through the pipes with great force. This method is much more effective and offers more water, making tubes cleaner. With this method all projectiles can be shot through.
