Gas Fire-Extinguishing Module MGPT 65-(60/80/100)-50

Modules MGPT-65-100-50, MGPT-65-80-50 and MGPT-65-60-50 are intended to be used as parts of gas fire-extinguishing installations and provide gaseous fire-extinguishing substance long-term storage under pressure and release into protected area to suppress fires of Classes A, B and C per GOST-27331 and fires at electric equipment:

  • HFC-125 TU 2412-043-00480689-96;
  • HFC-227ea TU-2412-049-00480689-96;
  • FC-5-1-12 Novec 1230.

The modules meet the requirements of climatic version UKhL, environmental class 4 per GOST 15150-69 within the temperature range minus 20°C to plus 50°C. Electromagnetic actuators at the modules with electric actuation have protection class IP65 per GOST 14254.

The modules correspond to seismic category I per NP-031-01 at location up to 20 m from the zero mark, meet the requirements of RD 25818-87, MU7.4-01, to group А by location, by functional purpose – to Version 1 for seismic loads up to magnitude 9 (at ductility level (DLE) and strength-level (SLE) earthquakes) per MSK-64 Scale.

As for NPP safety, the modules belong to normal operation systems (components) which are important to safety class 3N per PNAEG-01-011-97 (OPB-88/97).

The modules include:

  • Cylinder BPG-A-100 (80, 60, 40, 20)-65 TU 1423-011-18074387-2001 or BPKh-100 (80, 60, 40, 20)-65 TU 14-3Р-106-2009;
  • lock and release device (ZPU) of “Rotarex” with syphon eF8.658.008.

These modules are equipped with electric, pneumatic and manual actuators.

Hydraulic calculations of gas fire-extinguishing system pipelines are conducted per the method approved by All-Russian Research Institute for Fire Protection (VNIIPO) and actual normative requirements. In addition to a manometer installed at the lock and release device (ZPU) the modules can be equipped with electric pressure transducer providing generation of an electrical signal when the pressure in module decreases below the permissible limit.

The modules are completed with the entire spectrum of mounting parts and fixtures required to mount automatic gas fire-extinguishing installations:

  • High pressure hoses, electric pressure transducer, clamps and supports, pressure test and blowing rig, trolley, spray nozzles, nipples, fittings, adaptors, plugs, manifolds, pipes, tees, branches, etc.
  • Module Cabinet ShM-100 is intened to shelter MGPT-65 type modules with 100 liter capacity.
  • The mounting drawing of the Module Cabinet is shown in the figure. 
  • Module Cabinet for 6 items.

Trolley is intended to move the Gas Fire-Extinguishing Modules (MGPT). Capacity – 200 kg. MGPT Package is intended to store and move safely the Gas Fire-Extinguishing Module (MGPT) together with its documentation and kit of spare parts, tools and accessories (ZIP) in vertical position.
