Benefits of CE Door Closer
01/
Fire protection
Any door or opening in the firewall can cause damage, allowing fire and smoke to pass through. The fire may pass from one compartment to another and become more intense as the burning progresses.
It may also suffocate the smoke or toxic gases emitted from the fire, choke blind people trying to escape, and damage the building’s internal contents.
02/
Safety
As hardworking and kind as we humans hope, the reality is that we are not very reliable at all. In insensitive environments such as pharmacies, banks, or anywhere where people hardly need additional security protection, you may find a door closer to a specific place very useful.
03/
Keep the room temperature
UL door closer also play a role in maintaining the required internal temperature and reducing air in and out of the conditioning space.
04/
Privacy
Some residents may forget to close the door behind them. This requires a type of closure-it that is light enough to allow a weak person to open it without pushing it hard, but it still needs to close correctly and completely.
05/
Health
In tropical environments, the UL door closer on the external screen doors can isolate bacteria that carry bacteria, flies, mosquitoes, and other pests outside the house, thereby improving hygiene.
When the door is closed, the commercial kitchen’s smell will be localized and not spread to other rooms.
06/
Acoustics
Doors (especially fire doors) are suitable for reducing noise from one room to another. The more times these doors remain closed, the less noise is transmitted through the doors.
Of course, you can also take other measures to improve the acoustic performance of the door, such as installing batwing seals (located at the door frame rebate) or door sill seals (automatically descend from the bottom rail to the sill when the doors and windows are folded back) the door is closed.
Type of CE Door Closer
Overhead door closers
You will usually find these door closers inside the office or front door.
However, if you do not have many visits throughout the day, you can use elevated doors at your business’s front door. This type of door closer is suitable for buildings with heavy traffic.
Chain door closer
This door closer uses a spring installed in the hinge and is an integral part of its design. The spring can be visible or hidden in the tube and is more common in interior doors.
They are called double-acting spring hinges on doors that open in both directions. The self-closing hinge looks like spring but works like a closed door. It solves the gap problem and provides speed control in one component.
Concealed door closer
Concealed fire door closers provide overhead door closers’ function but are installed in the door leaf and frame. This installation is aesthetically pleasing and helps reduce vandalism, as most door closers are invisible.
The are available in spring or hydraulic versions on the market, and due to their lightweight, they are usually used for interior doors.
They will not appropriately work floor spring doors if installed on heavy commercial doors.
Surface-mounted door closers
Surface-mounted door closers are manufactured to be installed in the door frame, and a crossbar can be installed on the back of the door. They are small and can match the color of the door.
They are installed in the frame of the door and the bar on the back of the door.
Surface-mounted door closers are a cost-effective choice for other types of door closers. Another benefit is that they are easy to install.
Electric door closer
Electric door closers are also called automatic doors, electric releases, etc. It is a mechanism that realizes the automatic closing of the door leaf through electric control. Electric door closers are different from hydraulic fire door closers.
Application of CE Door Closer
Fire Doors
Under the NFPA 80, fire doors must be self closing. The simplest way to accomplish this is with a commercial door closer with a UL10C label showing approval for use on 3 hour fire rated door assemblies. If the door is a fire rated door, then a CE Door Closer must be used. Having a fire door that automatically closes and latches is very important for fire safety as it prevents the spread of fire.
Security Doors
Many security doors feature some form of automatic locking such as magnetic locks or electric strike locks. These doors are often accessed by a card reader or digital keypad. These doors must remain closed and locked in order to prevent unwanted individuals from entering the building. For this reason security doors must close after a person uses the door. To accomplish this an automatic door closer is used.
Hotel and Apartment Doors
Hotel or apartment doors are similar to security doors, where the residents depend on the front door automatically closing. If a hotel or apartment front entry door did not have an CE Door Closer, residents could forget to close the door, leaving their apartment or hotel room vulnerable to burglaries and unwanted vandals. Hotel room doors and apartment front entrance doors are also fire doors, so they must use door closers. This is a huge safety requirement because if there is a fire in hotel room, having that room's door automatically close, ensures that the fire is unable to spread through the entire hotel hallway.
Storage and Closet Doors
Storage room doors also benefit from CE Door Closer. Many storage rooms in commercial buildings are used to house janitorial supplies such as cleaning chemicals, brooms, and other equipment. Having an automatic door closer on the storage room door ensures that the door is always closed and locked, so unwanted pedestrians or children do not have access to the room.
Commercial Restroom Doors
When someone uses a restroom in a commercial building they expect privacy. Having a door closer on a restroom door, CE Door Closer ensures that the door automatically closes after a person enters or exits the restroom. This provides privacy that all people expect when using a restroom in any building.
Are There Specific Finishes Available for CE Door Closer?
Stainless Steel
Stainless steel finishes are popular for their modern and sleek appearance. They are resistant to corrosion and offer a clean and contemporary look. Stainless steel door closers are often chosen for commercial and high-end residential applications.
Brass
Brass finishes provide a classic and timeless aesthetic. While brass may require periodic maintenance to prevent tarnishing, many appreciate its traditional and elegant appeal. Brass door closers are suitable for both residential and commercial settings.
Bronze
Bronze finishes offer a warm and rustic appearance. They are well-suited for spaces with a more traditional or vintage design. Bronze door closers can add a touch of character to entrances in various settings.
What Is the Significance of the Fire Rating in a UL door closer
The fire rating of a UL door closer is a critical aspect, especially in the context of building safety and emergencies.
Fire Containment: The primary significance of the fire rating is its role in fire containment. During a fire outbreak, doors equipped with fire-rated closers help contain the flames and smoke, limiting the spread to other areas of the building.
Certification for Safety: The fire rating is often accompanied by a metal label or certification that verifies the UL door closer’s compliance with safety standards. This certification is crucial for ensuring that the UL door closer is reliable in emergencies.
When purchasing a UL door closer, checking the fire rating and associated certifications is essential to contribute to the overall fire safety measures of a building.
Process of CE Door Closer
STEP 1
Establish if your door is a fire or non-fire door. If the door is a non-fire door, then any CE door closer can be selected. However, it’s important to ensure that the operation of the door is controlled and not slamming, as this will prevent damage to the door and frame.
For fire doors, ensure the UL door closer is UKCA / CE marked and fire rated, and that you are selecting based on your application need.
STEP 2
Look for the fire rating.
This is a vital step in the process. If you’re installing a unit on a fire-rated door (typically found in commercial buildings) the closer must also be fire-rated. Look for a UL door closer that’s CE marked. This shows the product is fit for purpose and meets all of the legal fire safety requirements.
STEP 3
Determine the size of CE door closer that you need based on the height and weight of the door.
Large and heavy doors will require a closer with a higher power size. If you’re unsure about sizing, it’s best to choose a unit that can be adjusted during installation. It’s also key to remember that Fire Doors must have a minimum Power Size EN 3 to conform to EN 1154 standard.
STEP 4
Decide whether you need a surface-mounted or concealed unit.
Surface mounted closers are installed on the surface of the door and frame and are highly visible. Surface mounted units are also the easiest to install. Concealed closers on the other hand, are mounted within the door itself and are not visible when the door is closed.
STEP 5
Review the mounting requirements. You can mount your closer on either side of the door, but you must select a unit that is designed for that type of mounting.
STEP 6
Backcheck is a feature that’s supplied on only certain CE door closer models. Essentially, it limits the swing of the door to prevent damage to adjacent walls and frames when a door is being opened at speed or with force. Some CE door closers offer this feature as standard, however make sure that they have also passed EN 1154 CE requirements by checking the Declaration of Performance (DOPs).
STEP 7
Decide whether your closer should have delayed action.
A delayed action closer offers a period of delay from when the door is opened to when it begins to close. This makes them ideal for environments that require easy passage, such as on doors used by children, the elderly or wheelchair users.
STEP 8
Look for a closer that matches or complements the rest of your hardware. By matching your hardware selections you can add to the visual aesthetics of the room and the building.
Maintaining CE Door Closer
Maintaining CE door closer is important to ensure their continued function and longevity. Here are some tips to help you maintain your CE Door Closer:
Keep the Door Clean
Regular cleaning is important to keep your CE door closer functioning properly. Dust, dirt, and debris can accumulate on the door's sensors, causing them to malfunction. Clean the door regularly with a soft cloth and mild detergent to keep it free from dirt and debris.
Lubricate Moving Parts
In most cases moving parts, such as hinges, rollers, and tracks, should be lubricated regularly to keep them functioning smoothly. Use a silicone-based lubricant to prevent damage to the door's finish. However, always be sure to first check with the manufacturer’s instructions for proper lubrication guidance.
Check Sensors
The sensors on your CE door closer are essential to its function. They detect when someone is approaching the door and trigger it to open. Make sure the sensors are clean and unobstructed, and test them regularly to ensure they are functioning properly.
Inspect Seals and Gaskets
The seals and gaskets around your CE door closer help to prevent drafts and keep out moisture. Inspect them regularly and replace any that are worn or damaged.
Check for Wear and Tear
Regularly inspect the door for signs of wear and tear, such as cracks or breaks in the glass or damage to the frame. These issues should be addressed immediately to prevent further damage and ensure the door continues to function properly.
