Vanguard Oil and Gas Division, gaseous fire suppression, water mist and carbon dioxide




Vanguard Oil and Gas Division, aquasonic water mist fire suppression systemThe AQUASONIC Water-Atomizing Fire Suppression System is a revolution in Class B fire protection technology. The high performance fire suppression system is specifically engineered to protect special hazard applications including:

  • Combustion turbine enclosures
  • Machinery spaces
  • Generator enclosures
  • Flammable liquid storage areas



  • Safe for people
  • Environmentally safe
  • FM Approved
  • Effective suppression of Class B combustibles
  • Minimal water discharge
  • Optimized protected volume with minimal piping and system discharge devices
  • Flexible system piping and atomizer location
  • Fully self-contained skid for volumes up to 9200 ft3 (260.5 m3)
  • Automatic detection and actuation and/or remote manual actuation
  • ASME/PED Approved stainless steel water tank


Vanguard Oil and Gas Division, high pressure co2 tanksCarbon dioxide suppresses fire without leaving behind any residues after discharge thus avoiding damage to sensitive equipment. With no agent clean up, there is less downtime after an incident. When properly designed, the carbon dioxide system will suppress fire in Class A, B, and C hazards by displacing the air containing oxygen that supports combustion.


  • No residue
  • Non-corrosive and non-conductive
  • Suitable for Class A, B, and C hazards
  • Fixed nozzle and/or hose reel agent distribution
  • UL, ULC, and FM approved
  • In accordance with NFPA-12 – Carbon Dioxide Extinguishing Systems Application
  • Remote manual pull stations
  • Corner pulleys
  • Door closures
  • Pressure trips
  • Bells and sirens
  • Transfer switches
  • Time delays
  • Pneumatic switches
  • Weighing devices


Vanguard Oil and Gas Division, mini bulk low pressure co2 vertical tankBridging the gap between high pressure cylinders and low pressure bulk tanks, mini-bulk tanks offer capacities of 1,000 and 1,500 lb (454 and 680 kg). The Mini-Bulk Low Pressure Carbon Dioxide Systems provide an alternative to manifolding high pressure cylinders. The tanks are configured vertically to save valuable floor space. Mini-bulk tanks provide protection for non-occupied total flood, local application hazards, hose reels or custom designs such as inerting or spurt systems.

Each mini-bulk tank is equipped with a low-cost, high-efficiency, air-cooled refrigeration unit. The refrigerant media, R134a, is environment-friendly and efficient. Most system components are interchangeable between the mini-bulk system and the larger bulk storage tank system.


  • Skid-mounted bases for easy handling with a forklift
  • Automatic or manual protection
  • Suitable for Class A, B, or C fires
  • UL listed/approved releasing control panel
  • FM Approved
  • CO2 storage tanks available in 1000 and 1500 lb (454 and 680 kg) capacities
  • Hydraulic flow program for piping design
  • Control valves operate on 24 VDC
  • The ASME coded inner vessel does not require regular intervals of hydrostatic testing
  • Design allows tanks to be filled in place
  • Liquid level and pressure gauges allow in-place service, eliminating the need to weigh individual cylinders
  • Meets NFPA 12 requirements
  • Distribution of CO2  accomplished through the discharge valve, selector valve(s) or a hand hose-line arrangement
  • Hand-hose lines can be supplied from a separate low pressure storage unit


Vanguard Oil and Gas Division, bulk low pressure co2 horizontal tankThe Bulk Low Pressure Carbon Dioxide Systems are ideal for non-occupied fire hazards requiring large amounts of extinguishing agent in a limited space. A single bulk tank can store from 3 3/4 to 46 tons (680 to 41,730 kg) of carbon dioxide, which is maintained in a stand-by fire-ready state that allows the system to provide effective distribution of agent on demand. Bulk low pressure CO2 systems offer multiple discharge capabilities between recharges as an economical option.

The liquid CO2 is stored in an ASME coded pressure vessel equipped with its own refrigeration system. The temperature within the vessel is kept at approximately 0 °F (-18 °C) by maintaining the internal pressure near 300 psi (20.7 bar). Valve control is electro-pneumatic or manual. Each master and selector valve assembly consists of either a ball or a butterfly valve, a spring-return pneumatic valve operator and a three-way electronically operated solenoid valve.


  • FM approved and listed
  • Automatic detection and control
  • Class A, B, or C fires
  • Wide range of CO2 storage units available (3 3/4 ton to 46 ton capacity)
  • Hydraulic program for piping design and nozzle sizing
  • CO2 storage units are saddle mounted
  • Low-profile design
  • Meets NFPA 12 requirements
  • Selector valves with spring-return actuators, solenoid valves, and pneumatic delay timers available
  • Distribution of CO2 is accomplished through a selector valve, master/selector valve or a hand-hose line arrangement
  • Hand-hose lines can be supplied from a separate low pressure storage unit or connected to the same storage unit that supplies a fixed pipe system
