Q-BOX flameless explosion venting unit

The Q-BOX system provides flameless explosion venting for nearby equipment units, instruments and personnel. The basic features include:

  • robust and durable structure made of stainless steel; ATEX-compliant design;
  • seal type adapted to actual operating conditions;
  • hazardous area projection from protected equipment: 5 m.

Applications

  • Flameless explosion venting (with full safety of equipment units, instruments and personnel);
  • Explosion protection for processing instruments installed in large buildings or outdoor, potentially with personnel nearby;
  • Silo vessels cyclone separators and air filters.

Specifications

  • Explosion venting without flame propagation, overtemperature or egress of dust;
  • Low unit purchase costs (compared to other competitive types);
  • Robust and durable structure made of stainless steel;
  • Seal type adapted to actual operating conditions;
  • Application restrictions: Kst max. 200 bar×m/s; Pred max. 1.3 barg;
  • Hazardous area projection from protected equipment: 5 m;
  • ATEX-compliant design;
  • Reduces explosion gas temperature from 1500°C to 90°C;
  • Reduces pressure and noise to safe levels;
  • Panel closure trigger pressure at just 0.1 barg / 22°C;
  • The protected equipment operating pressure must be no more than 75% of the panel closure trigger pressure.

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.
