With PreVent, a ventilator removes combustible gases and prevents gas accumulation to improve overall manhole environment. According to Novinium, water control features limit exposure to salt water and debris, and the real-time smart monitoring system uses cloud-based sensors to predict incidents and transmit immediate alerts.
There is also a ventilated cover, crowned with water dams and air slots to limit water and salt intrusion.
Manhole events include fire, smoke and explosions.
