The weight of the chain is perfect, so the chains hang well and the size and shape of the clips is exactly the same as the ones they replaced. These Hilary’s vertical blind bottom chains are high quality. I am delighted with them. They also arrived earlier than expected.

Firstly, what is an window actuator and why does it need to be there? They are not all the same so it is important to look at the different types available in relation to the needs of a particular project. Then, wiring routes and concealment need to be considered. Without any intelligence, they are often operated in large poorly controlled ‘chunks’ of opening distance – associated with heavier oscillations around comfort set points, hunting, uncomfortable draughts, excessive energy consumption and potentially shorter actuator life. Its slim design, short length of the chain drive, and large strokes make the chain window actuator a great choice for a range of projects. Moreover, chain drives are easy to install and offer programmable parameters. When they are used as a pair, the option of the second DA actuator offers simple connectivity to the master chain drive. This saves on cabling, power, and isolation/termination points. 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.Chain actuators are ideal for window automation for intelligent natural ventilation systems or smoke control. They are precision designed and suitable for everyday control as well as complex control systems. 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.

An electric chain actuator is the perfect choice for Automatic Opening Vent systems. It is an affordable product that can turn most windows into AOVs that are suitable for natural ventilation as well as smoke vent systems. There are an increasing number of window actuators on the market of wildly varying quality and capability. 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. Alternatively, a matching cover profile might be an option. Again, this is often overlooked during the specification and tender process but a little thought in the specification, and preparation in the factory, can reduce cost and improve aesthetics later.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. Firstly, they deliver automated ventilation – increasingly chosen to add intelligence to the building’s ventilation, helping it breathe more effectively on its own.

Generally, a typical profile will use around 40mm of chain to bridge the profile from the actuators fixings to the sash. Therefore, a 265mm chain will give around 225mm clear opening depending on the profile and mounting arrangement. It took me a while to find these, as there are many flimsy, poor-quality alternatives online and in a local curtains and blinds shop. Equally, they are often a second thought, which can cause major headaches for designers, contractors and clients that have to pay to put them right, or live with the consequences for years to come.

It is important to get confirmation of this if more window actuators are required because this not only impacts on actuator costs but also on associated power supplies and wiring. If in doubt, consulting WindowMaster or fabricators early on may prove worthwhile. It is important to note that different window profiles have differing requirements for the number of operating handles. This applies to window actuators too. This is normally associated with the rigidity, or flex of the window profile around the pull point(s) and the frame’s capacity to maintain a seal around the perimeter of the vent. The motorization of bottom-hung windows is ideal for ventilating rooms, so it is possible to let light and air pass even in small rooms both in summer and in winter. Furthermore, the easy use and maximum safety allow for prolonged and long-lasting use of electric chain actuators for windows.

Most standard window actuators have little or no intelligence. They consist of a glorified bike chain designed to bend only in the required planes, a motor and set of gears. The chain actuators are on sale on Windowo at discounted prices. You can choose the electric bottom hung window that best suits your windows and doors. Scroll through hundreds of professional products and discover the characteristics of each hinged door motor: you can compare them and choose the one that's right for you. Research suggests that high level (typically two metres and above from floor level) top-hung outward opening windows are the most effective overall solution for natural ventilation.It is less associated with window actuator power or opening/closing ability and is therefore dictated by the vent fabricator or profile supplier. The vent width limit for a single window actuator can vary from profile to profile from 700mm to 1.500mm (eg Velfac @ 1.500), though for aluminium profiles 1.200mm is normally used as a rule of thumb.
