Take into account any reveal or sill that might limit the real clear opening achieved (Building Regulations, Approved Document B, 2007). Draughts when controlling CO2 in winter are reduced because a small amount of cold air introduced at high level mixes with warm air and carries further into the room before falling to body height. See our large selection of electric Single Chain Actuators used to open and close a window as part of a Natural Ventilation or Smoke Ventilation system.

High level top-hung outward opening windows can avoid the reveal or sill limiting the achievable opening areas. The longer the chain, the bigger the links need to be to maintain integrity and therefore the bigger the housing to hide it when it is withdrawn.They offer a wide range of force and stroke lengths that can be programmed into the actuator before installation, which makes them a versatile option suitable for different projects.

Your window opener must have the ability to monitor for entrapment on specified windows by communication via the microprocessors installed within the actuator and by monitoring in real-time the amount of electrical current being drawn and the precise position of the window to an accuracy of less than a millimetre. The sensitivity of the pressure safety must be adjustable, as the pressure safety function is a factor of the closing force of the actuator combined with the size and weight of the window, as well as the configuration of the window, its hinges and the rigidity of the profile itself. If at high level a route should be provided through the mullions without having to bridge the inside face of the profile.If vents are at high level, just preparing the mullions to allow cables to be pulled through allows cables to be hidden on top of the transom thus limiting their appearance on the face of the façade or windows. There are 240V actuators on the market, but these are generally designed for occasional use and are prone to overheating if used regularly, so are therefore normally avoided.

Therefore the overall performance and sensitivity of the system is dependent on all these factors combined and needs to be monitored and adjusted as the required forces can change during the life of the building. When purchasing a chain motor you will therefore have to consider whether to get an actuator with home voltage (230V) or industrial voltage (24V direct current). Once these questions have been resolved, power options, opening areas and window orientation need to be factored in. wide or more, the window or curtain walling supplier shall check whether two actuators are required.

It is important to note that different window profiles have differing requirements for the number of operating handles. The lifespan will depend on the quality of the motor and its maintenance, but high-quality motors, such as those you can find for sale here on Windowo, can last many years with adequate maintenance. Whether you want to match an existing brass chain, bronze chain, or stainless steel chain, we offer a range of finish options to suit your needs. Furthermore, the easy use and maximum safety allow for prolonged and long-lasting use of electric chain actuators for windows. Generally, a typical profile will use around 40mm of chain to bridge the profile from the actuators fixings to the sash.
