The benefits of using a vacuum, listed below, are numerous, and they offer increased reliability and a longer service life for Sprinkler Systems.
Yet to profit from the benefits of this new technology, the vacuum systems must be installed in compliance with the applicable rules and regulations: installation regulations, rules of the art, and the specific rules for vacuum systems.
The benefits that make the system reliable, cost-effective, ecological and durable:
- Standard* installation equipment and components, except:
- Control unit: vacuum sprinkler control unit
- Sprinklers: sprinklers operating in a vacuum
- Fast and easy deployment and operation, with low energy consumption.
- Cheaper maintenance and operation.
- Fast activation of the system: < 5 seconds.
- Dry system: no water + natural drying of pipes when on standby:
- Little/no corrosion, development of microorganisms, and hence of sludge build-up and system clogging.
- No need for internal treatment of the pipes.
- Possibility of using black steel (with factor C-120).
- No frost risks.
- No need for antifreeze (glycol, etc.).
- No need for heating.
- No leaks from sprinkler network into the external environment (potentially contaminating other systems).
- Required water density for discharge.
- No need to use drinking water, the following water sources can be used**:
- No pressurised air:
- No condensation, which would increase the corrosion phenomenon and frost risk.
- No air blown over the zone where the sprinklers are activated.
- Fast-arriving, full-jet water spray.
- Conversion of existing traditional sprinkler systems into a vacuum sprinkler system.
* Elbow bends, T-bends, steel pipes, eccentric reducers, valves, etc., complying with the various rules applicable to vacuum systems.
** The pipes that are upstream of the sprinkler network, and which are wet, must be adapted to the water source used.
Note: quantifying the benefits of the application of Vacuum Technology will depend on the project itself; you should therefore contact Vactec or its Representatives to assess the gains to be made and the conditions for attaining them.
