Types of heavy duty door closer

A heavy duty door closer is a hydraulic device that automatically closes a door after it has been opened. As the name suggests, it is ideal for larger or heavier doors that require more strength to close securely. These door closers are commonly used in commercial and industrial settings, such as office buildings, hospitals, schools, and factories. They are designed to withstand frequent use and provide reliable door-closing power.

They come in different types, including:

• Regular Arm Closers

  These are the most commonly used heavy-duty door closers. They consist of a hydraulic body, an arm, and a bracket. The hydraulic body is mounted on the door frame, while the arm and bracket are attached to the door and frame, respectively. They work by using hydraulic fluid to control the speed and force of the door closing. They are suitable for most commercial applications, such as office entrances, conference room doors, and storage room doors.

• Parallel Arm Door Closers

  These heavier duty door closers are installed on the push side of the door. The hydraulic body is mounted parallel to the top of the door and attached to the frame and the door using an arm and bracket. They are ideal for doors that require a more aesthetic appearance or where the regular arm closer would not function properly. They are suitable for high-traffic areas, such as hospital entrance doors and school building doors.

• Sliding Door Closers

  These heavy-duty door closers are specifically designed for sliding doors. They are usually mounted internally and work by using a hydraulic mechanism to control the sliding motion and closing speed of the door. They are suitable for commercial applications with large sliding glass doors, such as shopping malls and airport terminals.

• Heavy-Duty Automatic Door Closers

  These door closers are electric-powered and designed for automatic closing. They are equipped with sensors that detect when the door needs to be opened or closed, allowing for seamless automatic operation. They are ideal for areas that require wheelchair accessibility or where automatic doors are necessary for safety, such as emergency exits and hospital entrances.

• Concealed Door Closers

  These heavy-duty door closers are installed within the door and frame, making them invisible when the door is closed. They provide a clean and aesthetic look while still providing heavy-duty closing power. They are suitable for applications where aesthetics is paramount, such as high-end office spaces and luxury hotel entrance doors.

Function and Feature of Heavy Duty Door Closer

Heavy-duty door closers are installed on commercial doors, high-traffic areas, or doors that need to withstand harsh conditions. These door closers are designed to withstand frequent usage and extreme weather conditions, providing reliable performance for a long time. Their features include:

• Hydraulic Control

  Heavy duty door closers use hydraulic fluid to control the speed and movement of the door when closing. As the door closes, it compresses hydraulic fluid in the cylinder, controlling the speed and dampening the impact. This hydraulic control ensures smooth and quiet door closing, reducing noise and preventing damage to the door and frame. More importantly, it allows for adjustable closing speed, which can be customized based on the weight and size of the door or specific environmental needs.

• Adjustable Closing Speed

  Adjustable closing speeds ensure that the doors close at a speed suitable for the environment or door size. This feature makes them versatile and applicable in many settings. For instance, in quiet areas like libraries, the door can be closed silently. In high-wind areas, the speed can be adjusted to counter the wind pressure. Adjustable speed reduces wear and tear, preventing the need for frequent replacements and making them a cost-effective option for managing door systems.

• Adjustable Latching

  Heavy-duty door closers have adjustable latching, which ensures that the door latches securely every time it is closed. It ensures a consistent latch engagement, which is important for security and safety. Adjustable latching can be customized to suit different environmental needs, door sizes, or weight. It enhances the longevity of the hydraulic system by minimizing unnecessary tension or pressure during the closing and latching process.

• Adjustable Backcheck

  Backcheck helps prevent the door from being opened too far, which protects it from damage caused by walls or other objects. This is particularly important in high-traffic areas where doors are frequently used. The backcheck function helps ensure the safety of people and objects near the door. It can be adjusted to suit the wind pressure or environmental needs. For instance, in areas with high winds, the backcheck can be adjusted to counter the wind pressure.

How to Choose Heavy Duty Door Closer

Choosing the right heavy-duty door closer requires careful consideration of several factors to ensure optimal functionality, durability, and security for the specific application. Here are some key factors to consider:

• Door Weight and Size

  The first consideration should be the weight and size of the door. Heavier and larger doors will require more robust hydraulic door closers for effective control and durability. It's essential to select a closer model rated for the door's weight and dimensions.

• Traffic Volume

  If the door will experience frequent opening and closing (high traffic), consider a heavy-duty door closer designed for high-traffic areas. These models are built with more durable components to withstand constant use without compromising performance.

• Closing Speed

  Look for a door closer that allows the adjustment of closing speed. This feature is particularly important in settings where a slow close is desired for noise reduction or safety. In contrast, a faster close may be preferred in other situations.

• Hold Open Feature

  Some heavy-duty door closers have a hold-open feature that allows the door to remain open at certain angles. This can be useful in areas where doors need to be frequently left open, such as during moving furniture in or out.

• Material and Finish

  Choose a closer made from high-quality materials like solid brass, stainless steel, or heavy-duty aluminum. These options ensure longevity and can withstand different weather conditions. Also, consider the finish for aesthetic compatibility with the door and surrounding decor.

• Mounting Options

  Determine the preferred mounting option, such as parallel arm, regular arm, or top jam. Ensure the chosen heavy-duty door closer is suitable for the door's mounting configuration. Also, consider the installation method, whether it will be surface-mounted or concealed.

• Power Size

  Many heavy-duty door closers are categorized by power size, ranging from 1 to 6, depending on the door's weight and size. Consult the manufacturer's guidelines to determine the appropriate power size for the specific door.

• Environmental Conditions

  If the door closer will be exposed to extreme temperatures (hot or cold) or harsh weather conditions (rain, snow), choose a model specifically designed to withstand such environments. Some closer models have weather-resistant features for outdoor use.
