REMBE GmbH Safety + Control

TARGO-VENT is an opening angle limiter developed especially for explosition vents, which guides the explosion flame and pressure wave specifically into areas, in which there is no danger for the adjoining infrastructure.

TARGO-VENT dynamically and progressively cushions the explosion vents situated beneath it, and can therefore also assimilate large kinetic forces resiliently. TARGO-VENT absorbs the enormous repulsive forces of the explosion energy and guides the flames and pressure wave in the desired direction.

Depending on what’s customers requirements the the flame and pressure wave are diverted at a defined angle of approx. 30° to approx. 45° upwards or to the side. Facility operators can therefore minimise the safety areas around the vent opening. The utilisable area is increased.

A further advantage of TARGO-VENT: the module is available in all the usual explosion vent sizes, so that retrofitting in existing units can be done without a problem. Conversions or new buildings are protected by TARGO-VENT without the explosion safety concept of the existing facility having to be significantly altered.

TARGO-VENT is assembled on the explosion vent in a space-saving manner. There is no need for expensive baseplates or reinforcements. The system is made from maintenance-free stainless steel materials and, in combination with REMBE® explosion vents is type-tested in accordance with the ATEX Directive 2014/34/EU (ATEX 114) and authorised in accordance with (FSA 13 ATEX 1637).

The EXKOP® system provides safe, economic and easy explosion-, spark and flame front isolation. The quench valves protect interconnected equipment by high speed closure of a fast acting pinch valve.

The quench valve is triggered by 100 % reliable signal from explosion vent, the Q-Rohr® or by IR-, pressure or temperature sensors. The complete system is fail safe due to an integrated pressure storage tank and self-monitoring controller. In case of explosion the plant personnel can reset the EXKOP® system quickly and easily after inspection. Downtime is reduced to a minimum.

The smooth surfaces, in combination with the patented, sealing concept, enables this special explosion vent to be implemented in previously hygienicaly 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 vessel avoiding unwanted dead spaces and making it ideal for use with cylindrical tanks. If the EGV HYP 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 minimises 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 downtime.

Plant components like silos, mills, filters, collectors, mixers or dryers, in which bulks are processed, conveyed or stored are hazardous areas where fine dust can be found in quantities. Explosion solutions are required when ignition sources cannot be reliably prevented.

With use of the Q-Bic safety suppression system, the starting explosion is instantly detected by the redundant related detectors and the prompt blowing of dry powder within the endangered area extinguishes the flame. The explosion is extinguished at the point of ignition and cannot be discharged to the outside atmosphere. Q-Bic is especially suitable for applications with toxicants, which must not be released in case of explosion.

The Q-Rohr® is used for flameless exploting venting of machines in interior spaces at risk of dust explosions. Within this protective system the need for cost-intensive blow-off channels for conduction of the explosions outward is negated. Due to the patented system of flame trap retention, the Q-Rohr® Maintenance optimised setup of all the equipment in the immediate vicinity of people and machines. Maintenance Costs are replaced by a simple, visual inspection.
