Global Smoke and Environmental Ventilation Specialists
SE Controls is a leading international specialist in the design and delivery of intelligent smoke and environmental ventilation systems using façade automation as an integral part of the building envelope.
We provide solutions for life safety and environmental comfort within buildings, whilst ensuring compliance with legislation and improving operating efficiencies, be that for commercial space or residential accommodation.
With over 35 years experience within the façade automation industry, SE Controls offer a complete turnkey solution from design and manufacture to installation, commissioning and on-going maintenance, throughout the lifetime of a building.
Our products are Made in Britain accredited but designed and tested to international standards, ensuring our solutions are at the forefront of technology and regulation, globally.
Smoke Ventilation SE Controls offers a comprehensive range of natural and powered Smoke Heat and Exhaust Ventilation systems (SHEV) suitable for any size and type of building. Our systems are designed to facilitate the safe escape of occupants in the event of a fire and to enable the fire to be fought in its early stages.
Environmental Ventilation Environmental or Natural ventilation improves indoor environments, reduces CO2 emissions and is cost efficient. Adaptive environmental ventilation systems are less costly than traditional HVAC systems, being cheaper to install, run and maintain. Adaptive natural ventilation is leading the way for a sustainable future.
Façade Automation Automatically opening windows uses hardware, known as actuators or rotary handles, that fit directly onto the window system which push and pull the window open and closed, instead of operating the window manually.
Remote Services Using 4G communications technology and intelligent algorithms we can analyse the data collected from our systems placed within buildings to continually improve operating efficiencies and report back on the findings of our research to help you better understand your buildings.

SE Controls helps protect visitors at Dubai’s Palm Jumeirah Nakheel Mall.
Nakheel Mall, Dubai’s 435,000 sq.metre retail and lifestyle centre located in the unique Palm Jumeirah development, is using control solutions and 192 actuators from SE Controls as part of the fire safety and smoke control system at the new complex.
Designed by international architect practice, RSP, for Palm Jumeirah’s master developers, Nakheel, the new mall has more than 200 shops, restaurants and entertainment options, as well as a 15 screen cinema complex and a direct link to the new 52 storey Palm Tower residential development.
A key feature of the mall’s design is its ‘crystal dome’, a 25 metre high a hemi-spherical glass clad structure, which is bisected by a monorail station and is an essential part of the retail centre’s fire safety and smoke control system.
SE Controls became involved with Nakheel Mall, partly as a result of its success with another major retail development in Dubai, Dragon Mart 2, where 1100 actuators and control solutions were used to open skylight & vertical façade panels for smoke ventilation.
For Nakheel Mall, SE Controls, supplied, tested and commissioned 192 Twin Chain actuators and 48 SHEVTEC 8A controllers, which are used to automatically open the crystal dome’s integral glazed smoke vents, on both sides of the structure, in the event of a fire.
In normal operation the glazed smoke vents remain closed until triggered by a signal from the Nakheel Mall’s fire detection system, which are then automatically open the 192 Twin Chain actuators. This allows smoke to be vented from the building and enables escape routes to be kept clear for visitors and staff to leave safely.
The actuators are 24 Volt DC units and are tested to EN12101-2, while the SHEVTEC controllers (tested to EN 12101-10) also incorporate a battery backup to maintain operation in the event of a mains power failure.
Director of SE Controls Middle East, Madhava Prasad, commented: “We have a tremendous amount of experience and expertise in providing smoke control solutions in a wide range of projects and sectors across the globe.”
He added: “We use these abilities to support designers, fire consultants and engineers in the Middle East and ensure the systems are effective and we are delighted to have been selected for this prestigious project.”

SE Controls adds comfort and safety at prestigious Manchester residential development
An integrated smoke control and environmental ventilation solution from SE Controls is helping keep residents safe and comfortable at a prestigious 11-storey residential development in Manchester, which also incorporates the company’s intelligent temperature monitoring and control system, SE Evello.
Designed by SimpsonHaugh architects, Burlington House comprises 91 luxury private rental apartments with one; two or three bedrooms and is located in the historic Piccadilly Basin area adjacent to the Rochdale Canal and a number of heritage buildings including the Grade II listed Jacksons warehouse.
The building’s three-layered design combines the use of brickwork on its six lower levels with aluminium cladding and a glazed facade system on the upper two geometric structures to reflect the historic surroundings while creating a modern residential space.
As regulations dictate that residential buildings higher than three storeys require a smoke control system to be installed, SE Controls was approached to design an effective solution that ensured escape routes are kept clear of smoke if a fire should occur.
Also, as the building’s energy efficient design and use of large glazed areas has the potential for temperatures in corridors and circulation spaces to become elevated during summer months, SE Controls engineered the system to provide integral environmental ventilation and ensure temperatures are maintained at comfortable levels for residents.
To achieve this, the SE Controls solution utilises the system’s smoke shafts and two dedicated environmental fans to provide day-to-day corridor and stairwell ventilation, which alleviates any issues with building overheating while preventing the build up of stale air.
The SE Evello system not only monitors the temperature, but also controls devices such as the ventilation fans and smoke shaft vents with a self-adapting control algorithm, which targets ventilation to the warmest corridors or areas of the building, where the heat increase is greatest, while also reducing ventilation to more temperate zones.
Developed using a combination of extensive building studies, CFD modelling and data derived from live test sites, SE Evello’s algorithms constantly monitor temperature levels and provides predictive control over the opening of corridor ventilation louvres and the extract fan speed to ensure temperatures never reach excessive levels. The other main benefit is that stale air and odours that can build up in static air spaces are removed and replaced with fresh air.
While the environmental system improves comfort, it is the smoke control system that makes it possible. Burlington House uses two mechanical smoke extraction shafts and one air inlet shaft for make-up air for the lower six floors, while a single smoke shaft is used in the upper five levels with the addition of pressure sensors to prevent over-pressure on the escape door.
Two roof mounted duty and standby SHEVTEC fan sets serve the smoke shafts, which are actuated as soon as smoke is detected within the building. The smoke control system operates on a floor-by-floor basis to provide protection for corridors and lobbies adjacent to the escape stairs and ensure smoke is removed from the ‘fire-floor’.
Once smoke or fire is detected, the environmental ventilation system is over-ridden automatically and smoke is extracted from the activated floor with all other automatic opening vents (AOV) locked out to maintain compartmentalisation. Additional smoke vents at the head of the stairwell and roof remain open until they have been reset by fire-service personnel using the relevant tamperproof manual control point (MCP), which are located on every floor.
In addition to the wide range of specialised equipment installed on the project, including smoke control dampers, SHEVTEC grilles, MCPs and temperature sensors, the system is controlled by three OS2 SHEVTEC controllers with battery back up.
The system also uses SECloudlink™ to provide round-the-clock smoke control system status information and reporting to enable monitoring and system adjustments to be made remotely, as well as enabling preventive and corrective maintenance to be performed by maintenance teams.
