Series 240 PNT For Control Quality Air
The Model 240 PNT Pneumatic Temperature pilots are
designed for applications such as offices, schools,
hospitals, or others where the unit will operate with a
pneumatic temperature control system. The Model 240
PNT is specifically designed for the low air consumption
required in such systems. They are also recommended for
environments requiring rapidly changing loads or close
temperature control. An Air Pressure Pilot, an Air PRV
Regulator and a Series 2000 Main Valve Steam
Regulator must be used with the Model 240 PNT.
