Q-Box® R3leaf™
Sustainable flameless venting of dust explosions.
Like its two previous models, the new Q-Box® R3leaf™ guarantees safe explosion venting in manned areas. The flames are instantly quenched inside the Q-Box® R3leaf™ by the high-efficient cooling effect. The Q-Box® R3leaf™ is designed for dust explosion-prone applications of low design strength and the need for large vent areas such as required for filters, dryers, sifters, elevators or silos. The Q-Box® R3leaf™ complements the product line of REMBE® flameless explosion venting devices as is it optimised in terms of performance and sustainability. Based on systematic development the venting efficiency the maximum protected volume as well as the KSt value could be improved significantly. Hence, less flameless explosion venting devices are required, especially for larger vessels.
The main focus during the development of the Q-Box® R3leaf™ was on sustainability and the following core question: How can we truly challenge the status ”Q(uo)“? Responsibility and respect for our natural resources drove us to develop the Q-Box® R3leaf™ entirely in stainless steel and dispensed with stains, paint, coatings or welded seams. This enables simplified recycling and significantly reduces the logistical effort. In other words, the semi-finished parts are supplied compact, space-saving and individually, and allow to be assembled at all REMBE® satellites worldwide. In total, the same amount of Q-Box® require less storage space, less mileage and cause less CO2 emissions.
Application
The rectangular connection complements the dimensions of standard explosion vents, thus allowing it to be retrofitted to existing indoor and outdoor equipment. Q-Box® R3leaf™ is also suitable for outdoor application. Easy retrofitting: The dimensions of the Q-Box® R3leaf™ perfectly match the dimensions of REMBE® standard explosion vents.
Advantages
- Proven reliability and safety in a new, more efficient and sustainable design.
- Maximum process efficiency for the protected plant due to the flexible use.
- Perfect protection for people, the environment and the plant.
- Economical alternative to vent ducts.
- Maximum reduction in TCO (total cost of ownership) thanks to low maintenance requirements.
- Long service life due to increased corrosion resistance.
- Sustainability through product design, logistics and maximum venting efficiency.
- Easier recycling compared to painted steel.
- No false activations.
Mechanism
The special stainless steel mesh filter inlet developed by REMBE® cools the hot flame gases extremely efficiently (up to 1.500 °C (2.732 °F). This reduces the volume of gas ejected and extinguishes the explosion.
