Autoclave control
This new module has been developed by NHT to perform the automatic control of the pumps (up to three) working in an autoclave system, replacing or integrating the functions of a bulky and expansive electric panel.
Thanks to three pressure switches inserted in the plant, Pump Control 300 allows alternate activation e omogeneous usage of each pump, thus guaranteeing constant pressure even with simoultaneous water requests.
The device is very easy to install, can work in both automatic and manual mode and always monitors the operations performed by pumps, press switches and alarms. In the event of a pump failure, the connected protection turns on and the other pumps keep working.
Pump Control 300, when in manual selection, allows remote activation of each single pump and if connected to a float switch (Normally Closed position) prevent the plant from dry-running.
