The water curtain is activated by a temperature sensor which powers the Unic-05 actuators to open the valves in 4sec flat producing an almost instantaneous water mist through a spraying system.
The unique design of the Unic-05 features a sturdy, compact motor built integral with the housing. This enables the actuator to withstand high vibration levels. The torque is transferred from the motor shaft via a gear cassette designed to achieve a max torque of 40Nm and a travel time of 4sec for 90-degree rotation. All mechanical forces are contained in a horizontal plane enabling less wear on moving parts and longer life of components.
The Koei Unic-05 actuator has been vigorously field tested by relevant fire authorities and has successfully withstood all tests.
