Design, supply, installation, testing, commissioning and maintenance of HVWS and MVWS deluge systems for transformers, tanks, conveyors, cable areas and suitable industrial hazards across India.
An HVWS or MVWS system is a fixed deluge arrangement that discharges water simultaneously through open spray nozzles positioned around a defined fire hazard.
The nozzles, discharge pattern, density, pressure, orientation and water duration are engineered for the equipment or exposure being protected. Activation may be automatic through a detection and releasing system, manual, or both, according to the approved cause-and-effect design.
Water spray can cool surfaces, limit radiant-heat exposure, control fire spread, protect structural or process equipment and, for specifically designed hazards, support extinguishment or emulsifying action.
MVWS uses engineered spray nozzles and hydraulic conditions to produce a medium-velocity pattern suitable for defined cooling, fire-control or exposure-protection objectives.
HVWS uses higher-momentum spray selected for suitable oil-filled electrical equipment and other hazards requiring penetration, cooling or emulsifying action defined by the approved design.
Dedicated or approved water storage and fire pumps capable of meeting hydraulic demand and duration.
A release-controlled valve that admits water to the open-nozzle distribution network.
Heat, flame or other suitable detection, releasing panel, manual controls and supervised interfaces.
Approved nozzle type, K-factor, spray angle, material and orientation selected for the hazard.
Hydraulically sized piping, fittings, supports, strainers, test and drain arrangements.
Water-flow or valve status indication, local alarm and connection to the fire alarm or control system.
Transformer trip, fuel isolation, conveyor stop or other interlocks required by the cause-and-effect matrix.
Safe handling of discharge water, contaminated runoff and oil containment where applicable.
Review equipment, fuel, geometry, exposure, occupancy, drainage and available fire-water supply.
Define MVWS or HVWS objectives, applicable criteria, density, duration, zoning and actuation philosophy.
Coordinate nozzle selection, placement, pipe sizing, pump demand and water-storage requirements.
Install, flush, pressure test, functionally verify and demonstrate coverage where the approved procedure requires.
Inspect nozzles, strainers, valves, detection, release controls, pumps, alarms and obstruction risks.
Applications must be confirmed by hazard-specific engineering. Common project categories include:
| System | Discharge arrangement | Primary objective | Typical decision factor |
|---|---|---|---|
| MVWS | Open medium-velocity spray nozzles on a deluge network | Cooling, control and exposure protection for suitable hazards | Hazard geometry, liquid/process characteristics and required coverage |
| HVWS | Open high-velocity spray nozzles on a deluge network | Protection of suitable oil-filled electrical or high-hazard equipment | Equipment construction, oil risk, spray momentum and approved criteria |
| Automatic sprinkler | Individually heat-operated sprinklers | Local automatic control within buildings or storage | Occupancy and storage hazard classification |
| Foam-water spray | Open nozzles distributing a foam-water solution | Control of suitable flammable-liquid surface hazards | Fuel properties, containment and foam compatibility |
In India, IS 15325:2020 provides a code of practice for the design and installation of fixed automatic high and medium velocity water spray systems. Projects may also specify NFPA 15, authority requirements, insurer criteria, equipment-manufacturer recommendations or client standards.
Design considerations include hazard classification, spray objective, water density, nozzle angle and spacing, obstructions, wind, pipe hydraulics, deluge-valve trim, detection, interlocks, drainage, runoff containment, corrosion, testing access and maintainability.
Important: This page is general information, not a hydraulic calculation or approved design. Final system selection and sizing must be completed by competent professionals using verified site data.

Final MVWS or HVWS design requires verified site, equipment and hydraulic data.
A suitable detection system can release the deluge valve automatically, while manual release is normally provided according to the approved design. Activation also initiates alarms and required equipment shutdowns.
Open nozzles allow all nozzles in the selected zone to discharge together when the deluge valve opens, providing rapid coverage over the complete defined hazard.
No, but oil-filled transformers and reactors are common applications. Other uses must be justified by the hazard analysis, applicable standard and approved design objective.
MVWS may be designed for cooling or exposure protection of suitable tanks and vessels. Fuel properties, tank construction, spacing, wind, drainage and fire scenario must be evaluated.
Nozzle spacing and orientation depend on the listed spray pattern, distance, angle, obstruction, required density, equipment geometry, wind exposure and hydraulic calculation.
Maintenance includes nozzle and strainer inspection, obstruction checks, valve and trim servicing, detection and release testing, pump and water-supply verification, alarm checks and periodic functional tests.
