Menu guided, programmable operation modes:
- Leakage compensation or continuous flow
- Proportional or digital solenoid valve
|
Ex p- system with patented propor-tional pressure and flow measurement
- No ageing of membrane switches, no screws or potentiometers to adjust pressure or flow thresholds or purging time!
High availability due to PID- regulated pressure and proportional valve
- High availability based on constant cabinet pressure
- No waste of purge medium. Only the minimum quantity is needed to hold the cabinet pressure
- Increasing leakage caused by e.g. enclosure ageing is balanced and system availability is assured
- No flow noise and only small gas consumption in combination with solid enclosures
Purging with regulated pressure
- No overload of pressure sensitive enclosure parts, like membrane switch keyboards or windows
- Shortest purging times by exact measurement of purge volume by integration of the outlet- sided gas flow
Display
- Menu navigation and messages in clear text
- Online messages for operation and failure states
- Permanent pressure and flow monitoring
- Available languages: German, English, French, Spanish, Dutch
High operation safety
- Alarm messaging at LC-display
- In- and outputs for external safety chains
Ex i- operator panel BT851.xU
- For ergonomically control of the Ex p- system
- Connection to the control unit over 3 wires
Many years of experience in pressurized enclosures made the develop of this Ex p- system possible
