Operation 

 

Operating phases of the APEX (SILAS) pressurized cabinet 

 

The operation of the APEX (SILAS) pressurized cabinet can be divided into three 
phases, which are preparatory, purging and operating phase. 

 

 

Process diagram of the operating phases  

 

The APEX (SILAS) pressurized cabinet is built in compliance with the currently 
applicable guidelines and standards and fulfils the requirements specified 
therein. The processes in the respective states are listed in the following. 

 

Operating phase 

Requirements

Preparatory phase  

Mains voltage connected 

Build-up of internal pressure  

Purging time set 

Purging time has not yet

Flow rate ok 

Purging time is running 

Operating phase

Maximum pressure ok 

Operation enabled  

 

 

Preparatory phase 

 

The preparatory phase begins when the supply voltage for the APEX (SILAS) 
pressurized cabinet and the supply with purging gas is switched on. The 
purging gas flows through the purging gas valve into the APEX (SILAS) 
pressurized cabinet. 

Preparatory phase sequence: 

The influx of purging gas increases the internal pressure in the pressurized 
enclosure. 

 

The minimum pressure of the enclosure is exceeded. 

 

The purging gas valve opens.  

 

In the case of dust applications, the purging gas valve is replaced by the 
adjustable needle valve. 

 

The next phase, the “purging phase“ is initiated.
