IECEx and ATEX, CCC-certified pre-purge system for large Ex e motors
Features
●Purge flow rate up to 10,000 Nl/min
● Use CLAPS technology to ensure internal pressure of
the equipment
● Stainless steel shell structure
● Temperature range -20°C to +50°C
● Remote boot option
The PP series pre-purge system provides the necessary protection for large increased safety motors. The PP range offers pre-start ventilation flows up to 10,000 Nl/min, making it ideal
for large Ex e motors.
The system includes a control unit (CU) and a ventilation unit (RLV). The control unit contains pneumatic logic for monitoring and controlling air flow, pressure and purge time,
and provides system outputs. The RLV measures the purge flow at the outlet and provides overpressure protection for the machine.
