Definition Of Door Closer
A door closer is a mechanical device that is typically mounted at the top of a door and is designed to automatically close the door after it has been opened. It controls the speed and force with which the door closes, ensuring that it does so smoothly and securely. Door closers are commonly used in both residential and commercial buildings for various purposes, including security, energy efficiency, and convenience.
Door closers work by using a combination of springs and hydraulic or pneumatic mechanisms to control the movement of the door. When the door is opened, the closer's components are compressed or engaged, and when the door is released, the closer's mechanism gradually releases the stored energy, allowing the door to close in a controlled manner.
Different Types Of Door Closer
There are several types of door closers, and they can be categorized based on their mechanism, usage, and design. Here are some common types of door closers below:

3.Pneumatic Door Closer
These closers use air pressure to control the door's movement. They are often used in residential applications and screen doors.
4.Hydraulic Door Closer
Hydraulic closers use hydraulic fluid to control the door's closing speed and force. They are commonly used in commercial buildings.
5.Electromagnetic Door Closer
These closers use an electromagnetic mechanism to control the door's closing and opening. They are often used in automatic and access-controlled doors.
These are some of the common types of door closers available, each with its own features and applications. The choice of door closer type depends on factors such as door size, usage, aesthetics, and specific functional requirements.

How To Choose A Suitable Door Closer?
When choosing a door closer, several factors need to be considered to ensure that you select the right one for your specific needs and circumstances. Here are the key factors need to be considered below.
Consider the size and weight of the door as this will determine the type and strength of the door closer required.
|Maximum Door Weight
|Maximum Door Width
Different door types (wooden, glass, metal, etc.) may require different types of door closers to ensure proper function and compatibility.
Consider whether the door closer will be used in a residential, commercial, or industrial setting, as this can affect the choice of the closer.
If the door is intended to be a fire-rated door, make sure to select a door closer that meets the required fire rating standards. The fire rating of a door closer refers to its ability to meet specific fire safety standards and requirements when installed on fire-rated doors. Fire-rated doors are designed to resist the spread of fire and smoke for a specified period, typically measured in minutes or hours. To maintain the integrity of a fire-rated door, the door closer used on it must also meet certain fire resistance criteria.
In the context of fire-rated door closers, the fire rating is typically expressed in minutes. It represents the amount of time the door closer can help keep the fire-rated door closed and prevent the spread of fire and smoke when exposed to a fire. Common fire ratings for door closers include 30 minutes (½ hour), 60 minutes (1 hour), and 120 minutes (2 hours).
Determine whether the door closer will be surface-mounted, concealed, or overhead-mounted based on your aesthetic and functional preferences.The mounting location of a door closer refers to where the door closer is installed on the door and frame. The choice of mounting location can impact the functionality, aesthetics, and accessibility of the door closer.
Surface-Mounted Door Closer
Concealed Door Closer
②Accessibility for adjustment and maintenance.
③Suitable for various door types.
②Enhanced aesthetics, especially for architectural and design purposes.
③Reduced risk of vandalism or tampering
②May be susceptible to vandalism or tampering.
③Some users may find the arm of the closer as an obstruction.
②Accessibility for adjustment and maintenance may be limited.
③Limited compatibility with certain door types and sizes.
Consider the desired closing speed and control options, such as adjustable closing speed and hold-open features.
7.Aesthetics and Finish
Choose a door closer that matches the aesthetics of the door and the surrounding environment in terms of design and finish.
Accessibility standards for door closers are designed to ensure that doors equipped with door closers are accessible to and usable by individuals with disabilities. Consider whether the door closer needs to meet accessibility standards, particularly if the door is in a public building or used by individuals with disabilities. There are some factors need to be consider when think of the standard of accessibility.
Manual doors must be operable with a maximum force of 5 pounds (22.2 N) to initiate movement and 15 pounds (66.7 N) to continue the door in motion. Door closers should be adjusted to comply with these force requirements.
Closing Speed and Time Delay
Door closers should have adjustable closing speeds to allow sufficient time for individuals with disabilities to pass through the doorway. Additionally, certain doors may require time-delay features to allow individuals to enter or exit without having the door close too quickly.
If a door closer has a hold-open feature, it should be adjustable to hold the door open at the minimum required width for accessibility. The hold-open mechanism should not create an obstruction or barrier.
Clear Floor Space
Adequate clear floor space should be provided in front of doors to allow wheelchair users to approach, maneuver, and operate the door comfortably.
Visual and Tactile Signage
Doors equipped with closers should have appropriate visual and tactile signage to indicate the presence of the door and, if applicable, the location of the door opener button.
Determine your budget for the door closer, as there can be a wide range of prices depending on the type and features.
Basic Door Closer: A simple, surface-mounted door closer without many advanced features can cost anywhere from $20 to $50 or more.
Mid-Range Door Closer: Mid-range door closers with additional features such as adjustable closing speed and latching options can range from $50 to $150.
High-End Door Closer: High-quality door closers with advanced features, durability, and aesthetic finishes can cost $150 to $300 or more.
Commercial/Industrial Door Closer: For heavy-duty applications in commercial or industrial settings, the cost can go beyond $300, depending on the size and requirements.
10.Local Building Codes
Ensure that the chosen door closer complies with local building codes and regulations in your area. For example, Building codes and regulations in the United States are typically established at the local or municipal level, rather than at the federal level. Therefore, the specific requirements for door closers can vary from one jurisdiction to another. However, some common elements related to door closers that are often addressed in local building codes and standards across the United States include:
Building codes often specify that fire-rated doors must have self-closing devices, which can include door closers, to ensure that they close automatically in the event of a fire.
In areas prone to high winds or hurricanes, building codes may have requirements for door closers that provide resistance against wind pressure to prevent doors from being blown open or damaged.
Many jurisdictions require compliance with the Americans with Disabilities Act (ADA) Standards for Accessible Design, which may include specific requirements for door closers to ensure accessibility for individuals with disabilities. These requirements can include considerations such as the closing force and speed of the door.
Some building codes and energy efficiency standards may include requirements related to door closers to minimize energy loss through doors. This may involve considerations such as the sealing efficiency of the door and the operation of the closer.
Installation and Maintenance
Building codes may specify installation and maintenance requirements for door closers to ensure their proper function over time. This can include guidelines for installation height, location, and periodic inspections.

For DC-071, it is a universal model for all over the world, as we can check from product size and mounting distance. Besides of this, the outstanding features is CE Certification, with that certification, it is easy to estimate the quality of the item rather than we say “our quality is good, it is the best”. Besides of this, we also can do HOLD-OPEN function for this item. The hold open function of a door closer is a feature that allows the door to be temporarily held in an open position, typically at a specific angle. This function is useful in various situations, such as when you want to keep a door open for ventilation, ease of passage, or when moving furniture in and out of a room.
For DC-032, it is a typical model in this industry because it is the same as model DORMA TS-68. DC-182-5 is the adjustable door closer, from EN2-5, it can be used in different door weight and door width, optional function is Back-check and Hold Open. By the way DC-032 also can do Back-check and Hold Open. The back-check function of a door closer is a feature that controls the speed at which a door is allowed to open in the final portion of its swing or when it is pushed open forcefully. It is designed to prevent the door from opening too quickly or with too much force, which can lead to damage to the door, door frame, or adjacent walls. So that BC function is optional not the standard function because some countries do not need this one.
Our DC-032 and DC-182-5 all pass EN1634 certification. What is EN1634? Let us explain it: EN1634 is used to evaluate the performance of doors and door closers in fire situations and ensures that they meet specific safety standards. It is an important standard for architects, builders, and manufacturers to ensure that building components, including doors and door closers, meet the necessary fire safety requirements.
