ProCon low pressure water mist system
ProCon is our low pressure water mist system designed for protecting cable trays (PC-C) and industrial risks (PC-M).
The systems are flexible enough to tackle many severe fire risks from conveyors, cable trays to transformers whilst being tough enough to do so in harsh conditions.
Moreover, ProCon systems share a similar design and installation approach with our deluge systems (with open nozzles), but with up to 60% lower water supply requirements.

ProCon PC-M – Machinery protection
The ProCon PC-M water mist systems for machinery and object protection can be used to protect non-enclosed machinery with minimal water demand.
Although machinery spaces may vary in their application, they all tend to either process or contain some form of flammable material. For instance, these materials are often flammable fluids, such as hydraulic oil or lubricants but also solid materials.
Application examples:
- Conveyor belts
- Presses and stamping machines
- Motor test benches
- Compressors
- Hydraulic units including oil sump and oil tank
- Diesel emergency power generators
ProCon PC-M – Tested and approved
Particular hazard points such as the oil-lubricated bearings of steam turbines and generators can pose significant fire risks but also are at risk of severe damage with traditional water based systems.
Therefore, viking ProCon PC-M systems can protect such sensitive machinery with low volumes of water by benefitting from the increased heat capacity of smaller water droplets. In addition, ProCon PC-M systems can also be used for cooling, e.g. of glass cladding or steel structures. Numerous fire tests have proven that ProCon low pressure water mist systems suit myriad applications.
Finally, the system components and the design parameters of the system have been tested and approved by VdS Schadenverhütung and other independent test centres.

ProCon PC-M – System design
The ProCon PC-M system is a classic deluge system at heart and is designed as such. With a straightforward design manual to advise particular design criteria, those familiar with deluge system design can get started immediately.
The system is sub-divided into one or more extinguishing zones. Each zone is controlled by a fire detection system connected to a deluge valve.
