CAT Winder Features Suitable for windows over 300mm high Maximum possible window opening of 260mm Available in black, light grey and white Inverter bracket is powder coated to match the winder Extension pole can extend up to 3 metres to operate high level windows (sold separately) Please see technical specifications for maximum allowable window weights CAT Winder Applications Low level top-hinged windows Low level top-hinged windows can be operated using a CAT Winder with a handle Installation is quick and easy Operation is simple, with the occupant winding the handle to open or close the window as they desire. High level top-hinged windows If you have a top-hinged window that is out of reach, the CAT Winder with an eyelet can be installed and operated using an extension pole. It is important to note that the CAT Winder must be installed upside down, with an inverter bracket, to allow the eyelet to be at an appropriate angle for operation with the extension pole The inverter bracket is powder coated to match the colour of the winder. Please note: if the window has blinds, a CAT Winder with an inverter bracket may not be suitable, as it will protrude from the window sill and impede the blinds from operating.

As a highly experienced company in the field of automated windows and natural ventilation systems, part of our job is to help you develop accurate specifications for your project. Below are some of the most important considerations for you to take into account in the design phase of your project. Window Actuators Arens offer both chain and linear actuators that can be used for three main purposes: Allow manual operation of high level windows and louvres for natural ventilation Provide a fully automated natural ventilation system Facilitate natural and smoke ventilation systems Window Sizes Ideally, awning sashes should be at least 500mm high in order to avoid the need for chains to be shortened. Windows should also be 450mm wide or greater to ensure there is adequate space for the actuator to be mounted. Arens do offer some custom solutions for smaller windows, but early consultation will be required. If your design is going to incorporate wide sashes, it is important to consider that any window that is greater than 1200mm will require two points of attachment. This is recommended by many window manufacturers to avoid bending or twisting of the frame. Fastenings In high wind loads some fastenings will not hold to timber and aluminium sections. In coastal and exposed locations as well as multi-level buildings this is particularly important to consider. Likewise, if your project is going to incorporate any form of displacement air conditioning this can lead to increased pressure on the windows and attachments. Calculations may be required to ensure that the most appropriate fastenings are selected. Window Openings and Locations High level operable windows...

Have you got high level windows that you cannot reach to operate? The need to open these windows can become very evident in the warmer months. It provides a cost effective means of exhausting hot stale air from your building and replacing it with fresh air. Passive cooling is promoted and the occupants can experience a greatly improved internal environment and in turn, higher levels of thermal comfort. The operation of high level windows can result in significant energy savings, whether it is in a school, home or office. Particularly in the warmer months, by allowing the build-up of hot and stale air to escape from the building a more comfortable internal environment can be achieved. It can also see the activation of air conditioning delayed. As air conditioners can make up a significant proportion of building operating costs, even small reductions in their use can amount to significant savings. Natural ventilation also plays an important role in the health of building occupants. If stale air is not removed from the building not only can drowsiness result, but in some cases symptoms such as headaches, a sore through or irritated eyes. These symptoms can result in not only reduced comfort but also a fall in productivity. Arens International specialise in both manual and electric controls for remote windows. These can be used to operate various types of high level windows and louvres in both new and existing buildings. Our manual range incorporates a wide range of operators for single, multiple and wide sashes. They are reliable and cost effective, requiring no electricity and very minimal maintenance once installed....
