What exactly does a tilt-and-turn windows mean? Where does this strange term come from? What are the advantages and disadvantages of this opening mechanism? If you are curious we recommend you read our guide. You can find it on the Windowo blog. The electric chain actuator range (chain drives) is ideal for turning windows into auto-opening vents (AOVs) for daily ventilation and smoke control. Micro 02 Mingardi: the price remains low, but it costs a little more. However, the selectable stroke is an advantage that should not be overlooked; Calculate the geometric free area just using the rectangle or throat at the leading edge of the opening sash first. If slightly bigger areas are required then consider the triangles at the sides if they are allowed to be included. For example, a standard 265mm chain gives approximately 0.225m clear opening x 1m window width gives 0.225m2 clear opening per opening window. We are happy to help you, if you have questions about selecting the right window openers for your building.

Most quality window actuators look similar but how the actuator looks, while aesthetically important, has no bearing on how successfully the window actuator will deliver on its requirements. 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. A " window motor" generally refers to a motorized system designed to open and close bottom hung windows, which are casement windows that open to the outside. The opening and closing of top-hung windows can be automated for greater convenience and control. Topp C20: made in Italy with a double link articulated chain, contained in a special case, complete with support and accessories;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.

Aprimatic Apricolor Varia: an economical but very efficient chain motor, recommended for its excellent quality-price ratio; What are the key features to look for in a chain actuator for bottom-hung windows? Some key features to look for include weight capacity, chain length, compatibility with window type, and control method. Some other aluminium systems also allow this solution but low profile systems often offer little room to hide the window actuators, which are therefore likely to be surface mounted. This is where you might also want to consider actuator colour and finishes in the specification. 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.

We are specialists when it comes to choosing the right window openers for buildings. Our expertise is built on our knowledge of regulatory standards and experience from having completed thousands of projects across the whole of Europe. When the provider emits this event, it doesn't accept new requests until the connection to the chain Selecting high level openings minimises a number of risks. 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.

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. Secondly window actuators are also used to provide ventilation via out of reach openings using keypad control where manual winding gear is either considered too intrusive, expensive or high maintenance.

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. Most window openers used for natural ventilation are 24V DC which give higher torque capacity and makes them electrically safer when using the window profile for containment. 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. 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. Using the smallest window actuator possible will keep the unit size and cost down. 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. 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.

Take into account any reveal or sill that might limit the real clear opening achieved (Building Regulations, Approved Document B, 2007). High level top-hung outward opening windows can avoid the reveal or sill limiting the achievable opening areas. The MotorLink® actuator will detect if an object becomes trapped in the leading edge of the window and prevent it from closing by monitoring the amount of current being drawn and then reversing the actuator to release the obstruction. Their opening areas can be supplemented by manual low level windows if required for operation on hotter days. These are often limited to 100mm openings due to the risk of falling, and the risk of obstruction if opening onto a thoroughfare. Often the window profile can be used as a conduit for 24V actuator wiring. It may require some co-ordination during installation but the specification can offer the opportunity to do away with the ugly surface-mounted trunking that can spoil the overall look of the window system. In addition, many window actuators do not have pressure safety functionality. Typically window actuators have essential functions such as speed control to minimize noise.Triangles at the side of the opening should not be included if it is a string of opening windows (adjacent open vents effectively cancel out the triangles).
