In most cases, oxygen probes from thermo-control Körtvélyessy GmbH do not require an external reference air supply. To flush the probe, ambient air is fed into the probe via the corresponding Ø6 mm nozzle. This task is carried out by external supply units. These use their own diaphragm pump or the existing compressed air system.
Although the furnace manufacturer already installs such a supply unit on the system, it can also happen that a replacement has to be purchased. We have two common versions available:
- Installed in the ASB housing
- Open on mounting plate with welding rods
