High Pressure Water Mist (HPWM) Fire Suppression Systems
SOVATZOGLOU S.A. has established a technical cooperation with Marioff, a globally recognized manufacturer of High Pressure Water Mist (HPWM) fire suppression systems for applications with increased fire safety requirements.
This cooperation supports the implementation of advanced fire protection solutions in industrial facilities, energy projects, and critical infrastructure, where conventional water-based fire suppression systems are not the technically optimal solution due to equipment sensitivity, layout constraints, or operational considerations.
System Principle
HPWM systems operate by discharging water at high pressure through specially designed nozzles, generating a very fine spray. Fire suppression is achieved primarily through rapid heat absorption and effective control of radiant heat within the fire zone.
Compared to conventional water-based fire suppression systems, HPWM solutions require significantly lower water quantities, reducing secondary damage and drainage requirements while maintaining effective fire control.
Marioff System Architecture
Marioff HPWM systems are fully engineered fire suppression systems, comprising:
- High-pressure pump units with appropriate redundancy configurations
- High-pressure stainless steel piping networks
- Dedicated water mist nozzles selected according to space height, volume, and geometry
- Control and zone isolation valves
- System control and activation logic operating in coordination with the fire detection system
System zoning enables localized activation, limiting fire suppression to the affected area only.
Pump Units and Hydraulic Performance
Marioff pump units operate at pressures significantly higher than conventional sprinkler systems, enabling:
- Stable hydraulic performance across complex and extended piping networks
- Reliable operation independent of pipe routing and elevation differences
- Consistent spray characteristics at the nozzles
Pump configuration and redundancy are defined based on project-specific requirements and fire scenarios.
Piping Network and Nozzles
The HPWM piping network is specifically designed and sized for high-pressure operation.
Water mist nozzles are selected based on:
- Protected space characteristics
- Installation height and geometry
- Expected fire load
Proper nozzle selection ensures uniform distribution and effective fire control without excessive water discharge.
Control and Activation Logic
Marioff HPWM systems operate in coordination with the facility’s fire detection system.
Activation logic and sequencing are defined by the fire protection design to:
- Prevent unwanted system activation
- Ensure timely and controlled fire suppression
- Limit system discharge to the required zones only
Typical Applications
Within SOVATZOGLOU S.A. projects, HPWM systems are typically considered for:
- Data centers and mission-critical facilities
- Industrial installations with elevated fire loads
- Energy and utility facilities
- Underground or confined spaces
- Projects requiring effective fire suppression with limited impact on equipment
Final system selection is based on project-specific fire risk assessment.
Integration into Mechanical Design
HPWM systems are not treated as standalone fire protection solutions.
They are integrated into the overall mechanical design of the project and coordinated with:
- Other mechanical installations
- Fuel and hazardous fluid systems
- Operational and maintenance requirements of the facility
This approach ensures reliable system operation without adverse effects on the overall installation.
Standards and Implementation
Marioff HPWM systems are designed, installed, and commissioned in accordance with applicable international standards and project-specific authority requirements.
System performance is evaluated based on reliability, maintainability, and suitability for long-term operation.
Role of SOVATZOGLOU S.A.
SOVATZOGLOU S.A. is responsible for:
- Technical evaluation and applicability assessment of HPWM systems
- Engineering design and integration into the overall mechanical scope
- Installation, testing, and handover and commissioning
- Technical documentation and ongoing support
HPWM systems are implemented within real mechanical projects, with emphasis on correct application and long-term operational reliability.
