VSP-820 Automatic Purging Unit

ASD systems continuously monitor the air in the protected environment, potentially subjecting the system to contamination over time. In order to prevent the build- up of dust and dirt on sampling holes and pipe network, regular pipe network purging with compressed air is essential.

In contrast to conventional purging systems, the VSP-820 unit features a single built- in Solenoid valve, which initiates the release of air into the pipe network. This valve also increases the reliability of the system by protecting the unit from any compressed air damage and can be accessed through a control board integrated into the housing.

Installation cost is greatly reduced, thanks to the unit’s compact design, which removes the need for additional mechanical and electrical control devices. Further cost savings are realized due to reduced cabling and commissioning requirements. User-definable purging processes and customizable program features allow the VSP-820 to deliver continuous and uninterrupted airflow whilst optimizing benchmark preventative maintenance regimes, through automatic purging processes settable at specific times.

Designed with the engineer in mind, the unit offers additional flexibility through the use of an external push- button or central timer as an input to allow the initiation of additional manual or automatic activations of the purging process.
