Double action door closer

Types of double action door closer

A double action door closer is a device used to close double-action doors automatically. These doors can swing open in both directions. The door closer is mounted on the top of the door and uses hydraulic pressure to pull the door shut gently and securely. It ensures that the door will not swing open too far or too quickly, protecting the door and the walls. Here are the types:

• Hydraulic Double Action Door Closer:

  This kind of double action door closer uses fluid pressure to control the speed and force with which the door closes. It provides a smooth and quiet closure, making it popular for locations such as hospitals, schools, and retail stores. It can accommodate doors of various weights and sizes and require little maintenance.

• Spring-Loaded Double Action Door Closer:

  This door closer uses a strong metal spring to pull the door closed after it's been pushed open. It's a simple and affordable option for places with lighter doors that don't need as much control over how the door closes. These are easy to install and maintain, making them a good choice for interior doors in homes and offices.

• Concealed Double Action Door Closer:

  This kind of closer is hidden within the frame of the door and the floor, which makes it an excellent choice for places where a more subtle look is preferred. Even though it's concealed, it still offers excellent control over how the door opens and closes, keeping things safe and working smoothly. It's typically more expensive and needs more precise installation compared to other closers.

• Heavy-Duty Double Action Door Closer:

  These closers are made to work with very sturdy doors that see a lot of action. They use tough materials like strong metal parts and hydraulic systems to ensure the doors close correctly, no matter how much work they have to do. You'll find them in places like warehouses, factories, and other spots where the doors need to be very durable.

• Adjustable Double Action Door Closer:

  These closers let you change how the door closes by fine-tuning things like how quickly and with how much power it shuts. This adjustability makes them useful for places with different doors or where the needs could change over time. Schools and hospitals often pick these because you can set them up just right for each door.

Function and feature of double action door closer

When the door opens, the hydraulic door closer for heavy doors will automatically retract, pulling the closer back in and allowing fluid to flow from one side to the other. This will safely and slowly close the door while helping to control the speed and latch.

Double-acting closers have some unique features that make them suitable for double doors or doors that need to close from either side. These features include:

• Adjustable closing speed: Many double-action door closers allow adjustments to the speed at which the door closes. This ensures a smooth and quick closure, preventing loud noises or slamming. Adjusting the closing speed can also prevent damage to the door or frame and ensure safety, especially in high-traffic areas.

• Adjustable latching speed: This ensures the door closes securely at the latch and can be adjusted according to the desired speed. This feature helps prevent noise, door slamming, and frame damage. An adjustable latching speed also ensures safety by ensuring the door remains closed at the latch.

• Adjustable closing force: This allows the user to control the speed and force at which the door closes. This ensures the door closes smoothly and quietly, preventing frame or door damage. It also allows the user to adjust the closing force according to the weight and size of the door or environmental conditions.

• Adjustable hold-open feature: This allows the user to adjust the angle at which the door remains open. This is beneficial in areas where the door needs to be held open frequently, such as in conference rooms or kitchens. Adjusting the hold-open feature can also prevent unwanted slamming or closing of the door in high winds.

• Adjustable backcheck: This feature controls the door's movement and resistance when pushed from the back. This ensures the door doesn't hit the wall or frame, preventing damage. Adjusting the backcheck can also prevent the door from swinging too far open, which can cause injury or damage to people or objects in the vicinity.

Scenarios of double action door closer

Double action door closers are used in different situations and environments where doors swing both ways and need to be controlled and closed automatically. Some common applications include:

• Restaurants

  In restaurants, especially near the kitchen area, a double-action door closer is often used. It allows staff to move quickly while carrying items back and forth without having to push the door open each time. The door will swing and close, allowing for smooth delivery and collection of items between spaces.

• Hospitals

  These places have a lot of people going through doors with carts, gurneys, and more. A double-action closer helps move things without hindering traffic. Staff can push through double doors with supplies or patients without being stopped by the door.

• Airports

  Airports have many large, high-traffic, and heavy-duty double-action door closers. They let moving trucks, baggage carts, and other things go through without slowing transportation. Moving staff and equipment are not hindered by doors.

• Factories

  In factories, loading docks, and areas with large carts or moving parts, double-action door closers help machinery, pallets, and people move without being stopped by the door. They enable efficient transport and workflow without issues from the doors.

• Storage rooms

  Double-action closer is also applicable in stores and storage rooms. It allows workers to transport goods in and out of storage without being stopped by the door. This is especially useful for delivering large items or moving multiple boxes at once.

• Laboratories

  Many laboratories utilize double-action door closers to permit the easy passage of samples, equipment, and personnel. This is especially important in environments where hands-free door operation is necessary to maintain cleanliness or safety.

• Public restrooms

  Public restrooms commonly have double-action doors with closers. This allows for smooth entry and exit for users, including those carrying items or needing assistance. The closer ensures the door swings shut automatically, maintaining privacy and cleanliness.

• Libraries

  Many libraries have double doors with closers that allow patrons to enter and exit quietly and efficiently, even with books or other materials. The closer helps maintain a peaceful atmosphere by ensuring the doors do not swing open or closed too loudly.

How to choose double action door closer

When selecting a double action door closer for a particular application, consider the following key factors:

• Door weight and size

  The efficiency of a double action door closer is affected by the size and weight of the door. Larger and heavier doors may require stronger closers with higher spring resistance. In contrast, smaller and lighter doors may require closers with less spring resistance.

• Traffic levels

  If the door is for an area with high traffic, look for a closer designed for durability and frequent use. High-traffic areas may require hydraulic or pneumatic closers because they can withstand constant operations.

• Closing speed

  Consider the desired closing speed. Faster closing may be required for high-security or climate-controlled areas to maintain temperature or prevent unauthorized entry. On the other hand, slower closing may be preferable for safety and convenience in areas like schools or hospitals.

• Material and finish

  Choose a closer material that is durable and resistant to corrosion, particularly for exterior doors or those in humid or coastal areas. Select a finish that complements the aesthetic of the door and surrounding space.

• Mounting options

  Ensure that the mounting option of the double action door closer is suitable for the door and frame configuration. Consider whether it will be surface-mounted, concealed, or in-line. Surface-mounted closers are easier to install, while concealed ones offer a more aesthetic finish.

• Adjustability

  Look for adjustable door closers that allow customization of closing speed, latching action, and hold-open angle to meet specific requirements. This is particularly useful in settings where conditions or requirements change.

• Compliance with regulations

  Ensure that the double action door closer complies with industry standards and regulations, such as accessibility and safety requirements. This is particularly important for commercial spaces where compliance is mandatory.

• Budget

  While it is important to consider the cost, it is equally important to prioritize quality and suitability over cheaper options. Investing in a reliable and durable double action door closer can save money in maintenance and replacement costs.
