To mitigate the risk of rainwater ingress into the BESS and ensure optimal safety, consider implementing our DUAL-VENT + VIGISPACE solution. This integrated system enables gas detection and DUAL-VENT opening while effectively minimizing the intrusion of rainwater into the container. In the event of an explosion, the DUAL-VENT's incorporated vent will open as usual, while our VIGISPACE certified deflector redirects the flame upwards, enhancing safety measures. This innovative combination of our DUAL-VENT solution (featuring gas detection and blast panel) with the VIGISPACE deflector ensures comprehensive protection against potential hazards.

DUAL-VENT ACTIVATION WITH MINIMAL RAIN PENETRATION


The V-DEX diverter serves to redirect explosions within ducts, thereby averting the dissemination of flames or overpressures into connected vessels. This device effectively diminishes the risk of flame propagation.

EcoBOSS® Energy Management Systems reduce kW consumption by up to 80% for industrial ventilation systems. Years of research and testing by Boss Products engineers have shown that regulating fan performance based on spindle runtime is key to energy savings. Typical ventilation systems operate at full capacity, but studies show actual spindle runtime rarely exceeds 50% of capacity during 90% of an average production cycle. The EcoBOSS® system leverages the Fan Affinity Law for maximum efficiency. Combining advanced technology, systems engineering, and modern components, we offer three levels of control to optimize industrial ventilation.
