The temperature controller is a self-acting device that automatically controls the vapor / liquid flow depending on changes in the temperature of the cooled / heated medium and maintains the temperature of this medium at a constant level.
The automatic temperature controller does not require a power supply, so it continues to operate even during a power outage.
No electrical components required, temperature setting is done by turning the knob.

- The term withstand temperature refers to the maximum temperature at which the bellows can withstand internal pressure.
- The maximum operating temperature of the bulb for cooling purposes is 100 ° C.
- The model with a red handle is for heating, with a blue handle for cooling. You can determine their purpose at a glance.
- Excellent durability, high tightness thanks to the locking mechanism made of stainless steel and fluoroelastomer.
- The single valve and balancing bellows design provides stable temperature control regardless of inlet pressure fluctuations.
- It is easy to change the characteristics of the regulator by simply replacing the body and the thermocylinder.
- Wide temperature setting range, has many uses.
- The bulb is suitable for heating and cooling purposes, and is common to all sizes (15 to 25A). It is possible to select a model only for the temperature control range.
- Easy setting of the starting temperature by means of a knob.

How to use the steam chart
When selecting the nominal size of the temperature controller at inlet pressure (P1), outlet pressure (P2) and steam flow rate of 0.2 MPa, 0.15 MPa and 20 kg / h, respectively, first find the point of intersection (a) of the pressure lines on inlet 0.2 MPa and outlet pressure 0.15 MPa. From this point (a) draw a line down to the intersection with the line corresponding to the flow rate of 20 kg / h — point of intersection (b). Since this intersection point (b) lies between nominal sizes 15A and 20A, choose the larger of the two, 20A.

How to use a water chart
When selecting the nominal size of the temperature controller with an inlet pressure, outlet pressure and flow rate of 0.3 MPa, 0.15 MPa and 1 m3 / h, respectively, first find the intersection point (a) of the differential pressure lines (ΔP) 0.15 MPa (0.3 MPa - 0.15 MPa) and a flow rate of 1 m3 / h. Since this intersection point (a) lies between dimensions 15A and 20A, choose the larger of the two, 20A.
• If using model OB-30 or OB-30U and the medium is hot water, use the selection chart above.
