ATEX-certified pressure rotary lock

A pressure rotary lock is a system of two rotary valves interconnected by a pressurization chamber. The pressure rotary locks enable pressureless feeding or discharge of powders or liquids to or from overpressure or vacuum-pressure areas. The pressure rotary locks are installed at gravity transfer points at a maximum pressure differential up to 10 bars. If ATEX 95 certified, the pressure rotary locks can be operated in Ex-zones or as standalone explosion isolation systems.

  • Discharge of powders / liquids from overpressure or vacuum-pressure areas;
  • Feeding of powders / liquids to overpressure or vacuum-pressure areas;
  • Dispensing of powders / liquids;
  • Explosion isolation in Ex-zones;
  • Examples of installation locations: outlet connections of cyclone separators, air filters, or dryers.
  • A complete pressure rotary lock with automatic aeration / deaeration of the pressurization chamber;
  • Optional ATEX-certified versions available on request;
  • Optional DMT-certified flame-arrester versions with resistance to violent pressure shockwaves;
  • Double-wall casing permits heating;
  • Nominal diameter range: DN 50 to DN 1200, PN6 to PN 16;
  • Max. pressure differential ≤ 10 bar (DN size dependent).
  • Selection of optimized unit;
  • Delivery and installation;
  • Inspection and servicing.

Model approach to explosive safety in an industrial plant

Model approach to explosive safety in an industrial plant

Step 1
ATEX Audit

During the ATEX Audit, we will focus on deficiencies in explosive safety and indicate tasks that should be performed first to have the strongest impact on safety improvement.

Step 2
Protection Concept

The result of the ATEX Audit is also a preliminary concept of protecting the installation from explosion. It allows estimating the costs of protections. After testing the explosiveness parameters of the dust from the installation, we move on to the final concept and design.

Step 3
Design and selection of protections

After accepting the concept and testing the explosiveness parameters of the dust from the installation, we proceed to the final selection of explosion protections and create a design that takes into account all required changes in production.

Step 4
“Turnkey” delivery and installation

We coordinate the entire delivery and installation process of protections. We have our own service teams with experience in performing installation without the need to stop the investor’s plant operation.

Step 5
Execution of ERA and EPD

We conduct a post-implementation Explosion Risk Assessment (ERA) and prepare (or update) the Explosion Protection Document (EPD). We usually also conduct training for the crew in the field of explosive safety.
