Door Closer Overview
A door closer is a mechanical device that ensures a door closes automatically after being opened. Its primary functions include enhancing security, maintaining energy efficiency by controlling airflow, and ensuring safety by preventing the slamming of doors. The aluminum concealed door closer for fire rated door has an adjustable closing and latching speed, making it suitable for commercial or residential settings. For high traffic areas, our surface-mounted type provide heavy-duty performance with adjustable closing strength to accommodate any door size.
As a concealed door closer manufacturer, we are proud of our aluminum concealed product. It is an epitome of innovation, perfectly fitting for fire rated doors. It not only offers aesthetics due to its concealment but also ensures the utmost safety and compliance with fire safety regulations. With our surface-mounted type, you can securely and smoothly control the opening and closing of heavy doors. It is designed to withstand high foot traffic and extreme weather conditions, making it suitable for commercial spaces that require frequent use.
Door Closer Varieties
Closers come in several types, each designed for specific applications and aesthetic requirements:
- Surface-mounted closers: The most common type, visible on the door or frame. These include regular arm, parallel arm, and slide track varieties.
- Concealed closers: Fitted into the door or frame for a more discreet appearance, often used in interior doors.
- Hydraulic closers: Utilize fluid compression for smooth closing action, with adjustable speed and latching force.
- Overhead closers: Installed at the top of the door, available in various arm configurations.
- Floor spring closers: Mounted on the floor, typically used for glass doors in upscale commercial properties.
- Electromagnetic closers: Used in high-security areas or hospitals, often linked to fire alarm systems.
Each type offers unique benefits, such as the power efficiency of regular arm closers, the aesthetic appeal of concealed options, or the heavy-duty capabilities of floor springs for large doors. The choice depends on factors like door material, usage frequency, and specific building requirements.
Installation
To attach a closer to a door, follow these general steps:
- Use the template to mark hole positions on the door and frame, typically 95mm from the door hinge.
- Drill pilot holes using drill bit.
- Mount the closer body to the door using the supplied screws, ensuring the speed adjusting valve faces the front.
- Install the arm rod to the door frame, usually 30mm above the closer body.
- Attach the main arm to the closer’s pinion shaft, perpendicular to the door.
- Adjust the forearm length so it’s perpendicular to the frame when connected to the main arm.
- Secure the arm components together and make final adjustments to closing speed and power.
For regular arm installation, mount the closer body on the pull side of the door. For parallel arm installation, mount the closer body on the push side of the door and use an additional bracket on the frame. Always consult the manufacturer’s specific instructions, as installation details may vary between models.
Doors Requiring Closers
Closers are essential for various types of doors, particularly those in commercial and public buildings. Fire doors are the most critical application, as door closers are mandatory to ensure their functionality and maintain fire protection. Other doors that commonly require closers include:
- Passage doors in public buildings, offices, and meeting places
- Exterior doors for security and climate control
- Doors in high-traffic areas to prevent slamming
- Doors in healthcare facilities for hygiene and accessibility
- Glass doors, especially when using concealed or floor-spring closers for aesthetics
The choice of closer depends on factors such as door material, usage frequency, and building regulations. For instance, heavy-duty doors may require surface-mounted closers with specific force capabilities, while glass doors might benefit from more discreet options like concealed or floor-sprung closers. Additionally, doors in areas requiring high security or those linked to fire alarm systems often use electromagnetic closers for enhanced safety and control.
Hydraulic vs Pneumatic Closers
Hydraulic closers generally outperform pneumatic ones in most applications, offering superior control, durability, and versatility. Hydraulic closers provide more precise adjustments for closing speed and force, making them suitable for a wide range of door weights and sizes. They also offer better weather resistance and can withstand extreme temperatures, making them ideal for exterior doors.While pneumatic closers are more budget-friendly and easier to install, they have limitations:
- Less precise control over closing speed and force
- Shorter lifespan, typically requiring more frequent replacements
- More susceptible to temperature fluctuations, affecting performance
- Generally weaker closing force, making them less suitable for heavy or high-traffic doors
For demanding applications or long-term value, hydraulic closers are the preferred choice due to their consistent performance, longevity, and adaptability to various environments.
Duty Levels Explained
Closers are categorized into different grades based on their durability and performance, with standard duty (or medium duty) and heavy duty being two common classifications. The main differences lie in their construction, cycle testing, and intended applications:
- Cycle Testing: Heavy duty closers that meet the EN 1154 standard specify a single test duration requirement of 500,000 opening and closing cycles without significant loss of performance or failure.
- Applications: Heavy duty closers are ideal for high-traffic areas, exterior doors, and demanding environments. Standard duty closers are suitable for medium traffic areas like small commercial buildings, churches, and retail stores.
- Construction: Heavy duty closers are typically constructed with an aluminum body for enhanced strength and durability. They often feature a screw-tied spindle, providing a more secure and reliable connection, especially crucial in high-traffic or emergency situations like fires. In contrast, standard duty closers may utilize a press-tied spindle, which can be less robust.
- Force and Control: Heavy duty closers generally offer greater closing force and more precise control options, making them suitable for heavier doors or those subject to wind and stack pressure.
When selecting a door closer, consider the door’s location, size, and usage frequency to ensure optimal performance and longevity.
