Fire suppression Systems

Autonomous fire suppression system Impulse-BS

An autonomous system of local application SPGAU gaseous fire “Impulse-BS”. BS – means BOX SAFE!

Operating temperature in the protected volume: -10° to + 60°C Extinguishing fire class A2, B, and electrical equipment under voltage up to 1000 V Type of extinguishing agent – HFC-125 (0.9 to 4.5kg), HFC-227ea (1.1 to 5.5 kg).Operating pressure at 20°C-16bar. Low self-destruction thermosensitive tube Brand DeTec – 80±10°C Configuration (depends on a model): 1.0-5.0 L liter bottle (cylinder), locking and starting device with ball valve, siphon tube, a pressure gauge with a pressure switch, a safety membrane fitting Brand DeTec tube, a tube Brand DeTec – 5.0-10.0 m length, PG inlet gland for pipe mounting for tube – 20 pcs., tube cap, cylinder mounting bracket, label, passport (combined with the manual), carton tare.

Principals

Structurally Impulse-BS is a bottle of cylindrical form with a shut-off and starting system (S&SS), filled with a gas extinguishing agent (HFC Fluorinated Hydrocarbons).

The neck of the bottle by means of a threaded connection is established with a safety device S&SS, membrane and a pressure gauge (with built-in pressure switch). Through the fitting clamp, to a S&SS-ball valve, goes a connected thermosensitive tube –“Brand DeTec”, with the corresponding diameter, and finishing cap. To fix a module “Impulse-BS” and thermosensitive tube together, use an appropriate bracket.

 Usage

Fire fighting in facilities of server cabinets, telecommunications equipment, instrument and electrical enclosures, cabinets with flammable liquids storage cabinets securities, other electronic and technological equipment. SPGAU “Impulse-BS” designed for long-term storage under pressure and release into protected volume an HFC agent, extinguishing fires of class A2, B, and electrical equipment under voltage. The role of gas-propellant is played by clear nitrogen.
