Gas Fire Suppression Systems

MPZHU Tanks

CO2 Low-Pressure

Isothermal tanks СО2 low pressure MPZHU “Volcano”  are designed for extinguishing Classes A, B, C fire as well as live electrical equipment.

High-quality СО2 according to GOST 8050-85 is used in Isothermal tanks СО2 low pressure MPZHU “Volcano”.

The tanks includes the following main components:

  • Container
  • Heat-insulating casing
  • Cooling unit
  • Pipeline
  • Shut-off and safety devices
  • Control board
  • Fill-in nipples
  • СО2 weight control unit.

MPZHU “Volcano” are designed for prolonged storage of СО2 gas and its discharge into protected space through lock valve, distributing device, pipeline, and nozzles.

After СО2 discharge has occurred there are 48 hours for the СО2 refill and putting the system back into stand-by mode.

Control board provides switching on and off of the cooling device and electric heater for maintaining a working pressure in a container, and also provides control over locking device and other fittings.

Advantages of MPZHU “Volcano”:

1
The locking device has modified construction and consists of a valve with solenoid latch that provides valve opening for less than a second,
2
Telemetric remote control over pressure, temperature, СО2 level and weight, monitoring all units when refilling, storing and discharging СО2,
3
Instrumentation check and replacement, as well as maintenance and adjustment of safety valves, can be done on the pressurized system,
4
MPZHU is equipped with pump unit designed for independent refilling, topping-up, and transfer of СО2 aloft or long distance,
5
MPZHU has a modular construction and is delivered factory-preassembled,
6
Control, safety, and monitoring devices are securely located in heated cabinets protected against damages and unauthorized access.
7
Electric cabinet has explosion-proof design that allows installing vessels in B-1 locations as per Electrical installation code.
8
Container and piping has isolation and are protected against external effect with galvanized steel painted with.
9
Shut-off, distribution, and safety devices are manufactured from high-quality stainless steel.

Resume: MPZHU Volcano system features low heat transfer, low operation costs, and prolonged service life.
