Door operator for heavy hinged exterior doors – wind load up to 9 Beaufort2018-05-24T12:52:02+00:00

Problem

Normal hinged door operators may not be able to cope with hinged doors opening to the outside and therefore in part exposed to high wind loads. The wind prevents the correct opening and closing and in the worst case causes damage to the door and the façade, even people might get injured.

The DICTATOR solution

For such applications DICTATOR offers a special hinged door operator, the DICTAMAT 310-21. Two models are available: with 200 Nm and 700 Nm. The stronger model braves winds of up to 9 Beaufort. The driving unit achieves its power by means of a special gearbox. Safety sensors which supervise the whole door area ensure the safety.

Examples of such doors can be found in these applications:

Normale Obentürschließer lassen sich nur in Ausnahmefällen bzw. mit „Basteln“ an Rundbogentüren anbringen.

The special gearbox of the stronger model together with a 0.18 kW motor generates a force of 700 Nm.

Mounting a R1400 door check on the back of a flush door or one without lintel2018-05-04T09:03:22+00:00

Problem

The R1400 door check is mounted on the closing face of the door. For this type of mounting the lintel should start just above the door leaf, because the hook is normally fixed to the lintel. However, this is not always the case because the door leaf is often flush with the frame.

DICTATOR Solution

DICTATOR solved this problem with a small, inconspicuous bracket. It allows to mount the hook on a flush frame. The bracket facilitates the individual positioning of hook and door check, thus considerably expanding the application possibilities of the R1400 door check.

Normal type of mounting: here the hook can be fixed directly to the lintel.

By means of the bracket, the R1400 door check can be also used on doors where the lintel is too far above the door leaf or don’t have any lintel.

Door Closer for Semicircular Doors2018-10-22T09:30:35+00:00

Problem

Normally it is not possible to install traditional overhead door closers onto semicircular doors (or only when “inventing” a special construction). And this would considerably affect the special aesthetics of a semicircular door. And, when the semicircular arch is as distinctive as the one in the photo, there is virtually no possibility.

DICTATOR Solution

With the DIREKT door closer this problem can easily be solved. It doesn’t require any lever arms. One end is fixed to the door frame or the wall and the other one on the door leaf. The closing speed can be adjusted exactly to the requirements on site. And the DIREKT door closer makes sure the door is always reliably closed.

Door closer semicircular doors problem easy solved

Until recently a sign reminded users to always close the door because it is normally not possible to mount an overhead door closer on such a distinctive semicircular arch.

Now the door closes automatically. DICTATOR calculated the fixing points for the DIREKT and the carpenter’s shop Wendlinger from Garmisch-Partenkirchen/Germany mounted it perfectly.

Overhead door closers are very difficult to install on arched doors. Thanks to the DIREKT door closer, the door now closes automatically. Now, thanks to the DIREKT door closer the door closes automatically. DICTATOR calculated the fixing points for the DIREKT.

Door closer possible even when there is no space above the door2018-05-04T09:04:12+00:00

Problem

Entrance doors – also side entrances – should normally be securely closed. But what to do if there is no space above the door for mounting a normal overhead door closer?

DICTATOR Solution

The door closer DIREKT solves this problem. One of its ends is fixed to the door frame and the other directly on the door leaf. Its closing speed can be ajusted exactly to the requirements on site. It is also possible to adjust the closing speed and even close the door very slowly.

Sliding doors shall always close automatically, without current. Is there a mechanical door closer without much maintenance?2018-05-04T09:06:14+00:00

Problem

Sliding doors often remain open. However, there are many reasons why they should be closed, for example:

  • to prevent unnecessary heating due to temperature loss because the door is opened.
  • to optimize the use of air conditioning in cold aisle containments for server installations or data processing centres.
  • to ensure privacy and an optimum working and hygienic conditions in examination and emergency rooms of hospitals.
  • …and many more (as e.g. to prevent birds from flying into a building, e.g. in a church).

An automated door operator needs electricity. This means that an electrical connection is required on every door and power is consumed. And a door operator on a highly frequented door needs to be serviced often.

Sliding doors shall always close automatically, without current.

Sliding doors in hospitals – they should be always closed

DICTATOR Solution

The mechanical door closer for sliding doors DICTAMAT 50 easily adapts to the respective door situation – thanks to the many models. The DICTAMAT 50 needs no electricity for closing – no connection to the mains is required. The closing speed is adjustable, thus ensuring optimal safety for people and goods.

Closing front doors slowly and quietly2018-05-04T07:56:04+00:00

Problem

Often front doors equipped with an overhead door closer close too fast and with a loud bang – or they don’t close completely. In appartment blocks this often causes discomfort, e.g. when the banging front door interrupts a neighbour’s sleep. A front door that closes too fast also makes it difficult to pass through with e.g. shopping bags or with a stroller. Also people who are not so fast anymore may have trouble passing through the door without being pushed.

DICTATOR Solution

The gate closer DIREKT is often used for gates in fences, however, it is also suitable for front doors or entrance doors. It provides a steady, slow closing and makes sure the door closes completely – without loud noises and in spite of its low closing speed. This not only prevents the annoyance due to noise but also injuries due to the banging of the door.

The gate closer DIREKT can also be retrofitted and its external adjusting possibility allows to adjust the closing speed exactly .

Gates with ascending hinges close too fast. How to slow them down?2018-05-04T09:06:50+00:00

Problem

The property is situated on an ascending terrain. The gate(s) must have ascending hinges to allow opening them. However, when closed without manual control, the gates will develop a high speed, thus having a great risk of accident.

Consequences: Noise, damages, injuries.

DICTATOR Solution

The DICTATOR oil damper makes sure that the gate is closed in a controlled way at a speed adjusted on site, thus making sure nothing is damaged and nobody gets hurt.

The cold storage door doesn’t close completely – when closed in a hurry2018-05-04T09:07:18+00:00

Problem

Every restaurant, canteen and food store has a cold storage. As a rule, smaller cold storages have hinged doors. Since everybody is usually in a hurry, they don’t always pay attention that the doors are really completely closed. Also, due to the seals, the doors don’t close easily on their own. Through the remaining gap the cold air can escape, the cold storage becomes too warm and expensive energy is lost.

DICTATOR Solution

DICTATOR door checks make sure that the closing door is always reliably and completely closed. The user doesn’t have to make sure anymore that the door is really completely closed. He saves time, the routines become faster, and the door is always closed and energy saved.

Open sliding doors disappear completely in a wall pocket – but how to retrieve them?2018-05-04T08:29:22+00:00

Problem

In house building sliding doors are on the rise. Especially attractive are sliding doors which completely disappear in wall pockets and thus open the whole passage. But how to retrieve them? There are special handles sunk in the front face of the door that are available for this purpose.  In order to close the door, they first have to be folded out – and afterwards have to be folded back as otherwise the door won’t close completely. A very troublesome procedure!

DICTATOR Solution

The DICTATOR release buffer offers an invisible solution wich is extremely easy to handle: a short, slight pressure on the front face of the door is sufficient to let the door come out of the wall pocket.

How to limit the opening angle of emergency exit doors or doors in public buildings – without door stop on the floor?2018-05-04T08:35:22+00:00

Problem

“We have to limit the opening angle of the doors to prevent them from damaging the adjacent construction. But we cannot use floor door stops as these would be tripping hazards in the escape path.”

DICTATOR Solution

The DICTATOR back checks are fixed on top of the door to the door and the frame. They make sure that the doors don’t open in an uncontrolled manner and they limit the opening angle so the doors cannot hit walls, façades, windows etc. and damage them.

Gusts of wind knock hinged doors open – What can be done?2018-05-04T08:40:58+00:00

Problem

Many buildings have doors that open to the outside (e.g. emergency exit doors, entrance doors of public buildings, etc). When these doors are knocked open by gusts of wind, heavy damage can occur.
Possible consequences of a door opening without control:

  • The door is knocked open by a gust of wind or by storm and crashes into the façade or an object being in the range of the door (e.g. a car). The consequences: torn-out hinges, damaged overhead door closers, broken panes in case of glass doors, damaged façades etc.
  • The opening door hits a passerby or is torn out of the hand of the person who is opening it. This can cause considerable injuries.

DICTATOR Solution

Mounting a back check – with or without regulation. As soon as the opening speed of the door leaf exceeds a certain value, the back check goes into action and slows the opening motion of the door to a controlled speed. There is an appropriate model for every application.

Fire protection doors don’t close completely – due to air cushions or draught2018-05-04T08:46:26+00:00

Problem:

There are several situations which can cause fire protection or smoke control doors to not close completely, in spite of an overhead door closer:

  • The doors form a fire protection airlock where two fire doors are situated within a short distance. When the first door is opened and closed again while the second door remains closed, an air cushion develops which may prevent the complete closing of the door. However, when the second door is open, the first door often closes with a loud bang.
  • An access door to a small room with a window. Depending on whether the window is open or closed, the same aforementioned situation can occur.

DICTATOR Solution:

By now, many manufacturers of fire protection or smoke control doors have included the DICTATOR door check in their door approval or manufacturer’s declaration as complement to the spring hinge or the overhead door closer. The DICTATOR V1600F back check assures the final closing of the door by pulling it until it is securely closed. There won’t be no more partially open fire doors.  But it also prevents the door to close with a loud bang in case both doors are open.

Doors of nurseries, kindergartens and schools often cannot handle the rush of the children leaving the building and knock open2018-05-04T09:01:20+00:00

Türöffnungsbegrenzer Kitas Schulen ProblemProblem

Doors of schools, nurseries and kindergartens often have to stand the rush of the children who want to leave as fast as possible. The doors are knocked open regardless of the consequences. Even door closers with opening damping can’t withstand such a rush.

The consequence: broken overhead door closers, torn out hinges, damaging of walls or façades behind these doors and, in the worst case, even injuries

DICTATOR Solution

The DICTATOR back checks make sure that the doors cannot be knocked open. When the door is opened at a normal speed, the back check isn’t even noticeable. It doesn’t increase the effort to open the door. However, as soon as the door is opened at high speed, the back check enters into action and effectively dampens the door movement.
