Smoke ventilation systems today require sophisticated control mechanisms and integration with highly complex building management infrastructure. Whitesales have launched their latest innovation in mechanical smoke control which combines exceptional performance with outstanding aesthetics.
Essentially, Smoke Heat Exhaust Vent systems (SHEVs) keep escape and access routes smoke free and delay or prevent flashover – to slow or stop fire developing to catastrophic levels. Mechanical ventilation systems, in particular, provide exceptionally effective smoke control, as well as greater building design flexibility. The Es-SHEV Mechanical Pod is a modular smoke ventilation system that has been meticulously designed with many key features to ensure optimum operational performance.
The Es-SHEV gives a guaranteed flow rate and pressure and is available in a choice of sizes for smoke ventilation solutions in high-rise buildings. Supplied in a prefabricated, prewired pod, ready for a single lift to rooftop, it is unique in the market due to its quick and easy on-site installation.
The Es-SHEV smoke ventilation system can provide adjustable flow rates to run in escape mode and firefighting mode. The control system can be linked to a building central fire alarm via interfaces and Fireman Priority Switches. The mechanical ventilation units are designed to incorporate controls over various floor vents and electrical invertors within the control system to adjust extract flow rates. These invertors vary the fan speed, allowing the system to be run at various output levels in the event of fire.
Rigorously tested to ensure compliance without compromise, the Es-SHEV is a robust pod system delivered factory commissioned ready for install. It also features a Sertus control panel, part of the Whitesales smoke-control range, which provides customisable control for integrated smoke-control system components, such as vents and louvres. It contains an automatic transfer switch for three-phase primary and secondary supply, invertors, and a duty and standby fan changeover switch.
The aesthetically appealing design of the Es-SHEV features: a powder-coated steel box section, fully welded and load tested for structural integrity; powder-coated cladding, colour-coded panels and adjustable large, flat mounting feet to provide stable support with no damage to roof finishes. Anti-vibration mounts ensure smooth running of the fan with no stress to the frame structure, while the noise attenuator reduces sound pollution for adjoining properties and internal noise for tenants.
Increased lobby and corridor overheating has become a feature of modern living in city-centre multi-residential buildings. This is mainly due to centralised heat-generation systems which significantly increase heat build-up in common areas. Improved energy efficiency, air tightness and urban density are also contributory factors.
The secondary use of a mechanical smoke ventilation system is becoming more common and is an effective means of reducing temperature in areas deep within a building through the use of the smoke shaft as a cooling chamber. The system provides negative pressure within the communal areas to draw air up through the building and works most effectively when combined with low-level inlet air.
The Es-SHEV Environmental Pod is an additional component which is integrated into the Mechanical Pod by means of a fireproof damper and includes an energy-efficient extract fan controlled by thermostats and smoke-shaft vents at each level. The system automatically modulates the internal temperature and shuts down immediately if a fire signal is given.
Offering unsurpassed performance and ease of installation on-site, these two pod systems are truly a revolution for smoke mechanical smoke ventilation.
