Professional press Man is a simple but yet efficient controller for maintaing constant pressure in heating and ventilation environments. It is charactized by a very robust construction and extremely simple user interface.
Press Man controls the PROFESSIONAL HVAC pressure from an pressure transmitter with an analog output mounted directly in the ventilation system. Difference pressures can be obtained by incorporating mecanical blends etc. IP54 grade and integrated keys / display makes Press Man well suited for many applications.
Press Man has a setpoint, which is controlled by the arrows. A single press will put the setpoint one up or down, holding the arrows will make the setting change fast while pressed. Measured pressure will be displayed pr. 5 sec after keys have been released
Press Man has two relay outputs, the first is used on ON/OFF by the key setting, the other is used for alarming. ON/OFF is activated as the key is activated, the alarm output will be active when the output can not be reached whithin 30 minutes !. Means, that if the output internally is UNDER or OVER the MIN/MAX settings, the relay will activate. Flashing LO or HIGH in display
Press Man can indicate the real output for the attached speed controller, OR, it can indicate the real input from the attached pressure professional transmitter. Both values will indicate in percentage (0-100) of input and output)
Press man can be 100% stopped, pressing the ON/OFF button. Display will indicate OFF and the DC output will be forced to 0, as will be the 2 relays. Press man has individual settings for minimum and maximum speed for the attached speed controller. Settings to be controlled by MIN/MAX buttons. Parameters for Proportional Band and Integration Time is done from the keypads as any other parameter. The PI regulator will meassure the pressure, compare it to the setpoint and try to maintain the dc output to make the real pressure as close to the setpoint as possible. |

Pressure controls serve various functions, which may be divided into control and protection functions. Examples for control functions are compressor cycling, pump-down or defrost control. Protection functions include, pressure limiting and cut out against excessive pressures, against loss of charge or for freeze protection.
Our pressure controls are equipped with display scale and pointers to indicate the approximate settings. The display professional scales are printed in relative pressure units "bar" and "psi". For precise setting of the controls, external gauges must be used. |

Almost every pneumatic tool would have the max. torque at around 6 bar. Higher pressures (which is often the fact as many users just plug in the tool and use the prevailing working pressure f. inst. 8 or more bar) is just waist of energy and money. It would not give more torch - on the contrary - it is just changing into heat. And many available pneumatic tools on the market can only withstand a max. pressure of 8 bar.
If the user dismount the professional hose from the tool or outlet directly a residual pressure would still prevail on the secondary side of the regulator. This residual pressure could make the pneumatic tool to work for a short period of time. An unintentional activation of the tool could have desastrous consequences - no matter the type of pneumatic tool. The worst incident that can happen is on a pneumatic tacker, nailgun or the like. An unintentional activation on the trigger f. example can result in 5 - 10 shots. No reason to say that bad enjuries would be the result.

... fast, accurate, highly-dynamic.
Proportional cocks of the tecno series are piezo controled pressure valves with electronic pressure control.
Piezo technology offers highest dynamics with lowest power consumption. High venting and exhaust capacity supplies the main valve. The industrial pressure sensor measures the active output pressure. An integrated electronic automatic controller compares the sensor signal with the electrical set value and regulates the output pressure precisely on the given set value.
These features characterise HOERBIGER Piezo Proportional Valves:
- extremely short reaction time
- virtually infinite resolution
- lowest power input. |
