The DC-120 is our largest unit and has everything built into a single case. This unit is designed for fixed applications and facilities the manual setting of up to 4 different fireball sizes for instant recall.
The effect is ignited by a pilot flame which has full flame monitoring and feedback as standard. The simple closure of a pair of volt-free contacts triggers the effect, the system then auto-resets for the next cue.
Cycle times depend on gas pressure and size of fireball selected but are typically around 20 - 120 seconds. The DC-120 will produce fireballs up to 5m in diameter. All pipework is standard 4" and all safety valves are pneumatic with spring return.
