Door closers
A door opener is a device that is installed on the door and performs the function of closing it in a CONTROLLED manner. Door machines are most commonly used in public buildings - business centers, offices, shops, schools, cinemas, etc., but also at home. There are a variety of reasons and applications for use, with the most common being used to keep the door closed limiting the spread of fire and smoke in the event of a fire or keeping the room temperature down. The automatic doors that you can purchase from Intesa's online store are from proven manufacturers such as ABLOY OY, ISEO, MAB. When choosing an automatic door opener, it is important to consider the width of the door, the weight, the intensity of use and also to what extent the device will be exposed to weather conditions. There are different types of vending machines, from the simplest spring-loaded, to vending machines with a complex device and several built-in functions. There is a difference in price between different manufacturers, but mainly the price determines the various special properties that the vending machine possesses. The colour and finish of the vending machine body can also influence the price. According to the application or the way of installation, vending machines come in several types: top-mounted, floor-mounted or built-in. Automatic door openers are available with different types of arms - sliding arm or scissor arm. According to your preference, you can also choose their function - with or without door hold-open. Vending machines are available with different "strengths" to be able to "service" doors of different sizes and weights depending on the needs of each. Larger and heavier doors require more force to close. The strength of the operator is indicated by numbers from 1 to 7 according to the classification of the European norm EN 1154, the standard for classifying door operators.
