Transformers are electrical devices which convert alternating currents from one voltage to another, making them vital for any operation to run smoothly. The Ceasefire Watermist Auto-Quell System is a revolutionary, all-purpose detection and fire suppressant solution for transformer fires.
The system consists of a network of detection devices, special Watermist nozzles and a connection to a water tank installed in the local environment of the transformer. In the event of a fire, the system is programmed to kick into action in seconds. The specially designed nozzles dispense Watermist, made up of microscopic droplets of water (below 120 microns), onto the fire affected area, quickly putting out the flames as well as bringing the temperature down to non-combustion levels.
Entirely self-activated and requiring no human intervention, this integrated system provides a complete detection and suppression solution for transformer fires, working quickly to save property and lives. What's more, since the Auto-Quell System is Watermist based, it has no long-term effect on the work environment and operations can resume without any time lost.
Multiple Applications: Works on A, B, C and Electrical Fires, and is suitable for a variety of applications.
Self-Contained: The system is entirely self-contained. It does not require any power supply and will function normally in the event of a power outage.
Self-Actuating : Featuring an inbuilt detection mechanism that leads to instant and automatic activation, the system eliminates the need for human intervention.
24x7 Protection: Being automated, the system is in a perpetual state of readiness to combat a fire as soon as it breaks out.
Extended Reach: Includes flexible tubing that can reach difficult-to-access areas that may not be able to accommodate any other means of detection.
Quick Installation : Simple design, and can be installed within a few hours, which means a significant reduction in labour costs and downtime.
Long Lasting : Its rugged quality ensures it can withstand even harsh conditions where other types of detection systems might be rendered inadequate.
Environmentally Friendly, no ODP:Unlike other firefighting agents like Fluorocarbons, CO2, Dry Chemical Powders, etc., Watermist does not have any effect on the ozone layer nor does it contribute to global warming.
Non Conductive: The droplet size is <100 microns. Such a small-sized droplet has little kinetic energy. Being light, it floats in the air and is non conductive up to 35kva.
High Standards :Built to Ceasefire’s high standards, which are in compliance with international quality standards.
Low Water Usage with Mist of 60-100 microns: With normal firefighting systems, only about 5% of water directed at the fire is actually used to put out the fire. Watermist not only uses less water to put out fires, it also uses only 20% of the water a conventional water-based system uses.
Extra Security for People – Screening: The small droplets of mist fall over a larger surface, creating a perfect barrier for thermal radiation, thus providing effective protection against fire for firefighters and people in the vicinity.
Post Fire Damage Reduction :About 80% of the damages resulting from a fire are not caused directly by the flames, but by the extinguishing action. Since the mist, with an appropriate (high) degree of dispersion, fully evaporates in the fire environment, it leaves behind no collateral damage.
Safe for People and the Environment : As the mist comprises of water, it does not expose people to chemically active substances, ensuring it can be safely used with no risk of medical problems.
Economical: Water as an agent does not cost anything. Traditionally the amount of water required is significantly low. Which in turn means smaller water reservoirs and pumps with lesser construction and procurement costs.
An Alternative to the Traditional Sprinkler System : Can potentially replace a building’s sprinkler system as it works faster than water, resulting in less fire damage and doesn’t soak the premises in the process of putting out the fire.
