REMBE Safety+Control

The smooth surfaces, in combination with the patented, full surface and tapered sealing concept, enable this special explosion vent to be implemented in previously critical plants, e.g. spray-dryers with/without wet cleaning, fluidized bed dryers, filters and mixers.

EGV HYP successfully passed the cleanability tests conducted by the commission of the EHEDG (European Hygienic Engineering & Design Group) and confirmed its suitability for CiP cleaning.

The EGV HYP can be adapted to the radius of the container avoiding unwanted dead spaces and making it ideal for use with cylindrical tanks. If the product is to be used in outdoor areas, a closed cell silicon cushion insulation is available to prevent the build up of deposits that may occur when the temperature drops below the dew point. Insulation also minimizes temperature and energy losses.

These features of the hygienic design of the EGV HYP improve product quality and also protect processes against contamination and production standstills.

The Q-Box guarantees safe explosion venting in production halls by facilitating pressure relief in the smallest spaces, indoors and outdoors. The Q-Box with an integrated rupture disc instantly extinguishes flame gases on the inside by efficient cooling and reduces the effects of the dust explosion to a level which can be disregarded.

The Q-Box is designed for plant components that are at risk of dust explosions, such as filters, elevators or silos and large explosion venting areas – it can be used in a wide variety of applications across all sectors. The rectangular connection complements the dimensions of standard explosion vents thus allowing it to be retrofitted to existing indoor and outdoor equipment.

In comparison to other relief systems such as blow-off channels, the Q-Box is significantly more economic. Reasons for this include the reduction of venting duct running costs and external maintenance.

Innovation is a tradition at REMBE®. In the area of explosion safety, the invention of flameless venting solutions – like Q-Rohr® and Q-Box – is probably the most important in the history of the company.

We have continuously developed and improved these products since the 1980s and they are now in use worldwide. The Q-Rohr® and Q-Box can be found in a whole range of sectors from the food processing industry to chemicals and pharmaceuticals. The advantages of flameless venting are immediately obvious: the entire production process remains inside the building and there is no need for expensive, bulky venting ducts that require modifications to be made to existing structures. The integrated explosion vent is fitted with a signaling unit that immediately reports any incidents to the process control system. The special stainless steel mesh filter inlet ensures that the pressure rise and the increased noise level associated with free vented explosions are massively reduced to negligible levels in the production room. Dust and flames are retained by the mesh filter inlet.

The Q-Rohr® has a round design. Consequently, it is vacuum resistant and ideal for the protection of pneumatic conveying systems as well as many other applications.

The Q-Rohr® and Q-Box also compare favourably with active fire extinguishing systems. They generate no running costs, false triggering damages only the bursting disc and the product remains unaffected. No regular maintenance is required, an annual visual inspection is more than adequate.

The products are certified by ATEX and also comply with many other currently relevant standards.

The Q-Rohr® can now also be used with metal dusts. Due to their extreme properties in explosive situations (e.g. temperatures can be twice as high as those with most other dusts), metal dusts create special challenges for protection systems. The Q-Rohr® is the first system to be certified in accordance with DIN EN 16009.
