Door Closers for Smooth Closures

What is a door closer?

A door closer is a mechanical device designed to automatically close a door after it has been opened so you don’t have to do it manually. Proper door closer fitting is necessary to ensure the door functions smoothly.

One of the most overlooked issues in modern spaces– whether at home, in offices, or in commercial buildings– is the impact of poor-quality door hardware. Subpar door hardware can lead to a host of problems:

• Safety Concerns: Doors that don't close properly may remain partially open, compromising security and allowing unauthorized access.

• Noise Interference: Loud door slamming from faulty closers creates constant disturbances, particularly in shared spaces or offices.

• Damage to Walls and Frames: Without proper control, doors can slam into walls or frames, causing dents, cracks, or structural damage over time.

With over 2 decades of experience, Ozone understands that modern living requires smart, effective, and aesthetic solutions. We combine thoughtful engineering with innovative designs to create door closers that ensure durability and smooth operation, making everyday living more secure and convenient.

Types of door closers

Concealed Door Closers

These closers are designed to be hidden within the door or frame, making them nearly invisible when the door is closed. These closers maintain a clean, minimalistic appearance while providing the same functionality as standard door closers.

Overhead Door Closers

This is the most common type of door closer found in both residential and commercial spaces. They are installed at the top of the door, typically mounted either on the surface of the door or the door frame, with the closing mechanism positioned overhead. It has two sub-types:

Track Arm Door Closers

• It uses a sliding track mechanism to control the door’s movement, providing a smooth and quiet closing action.

• These are ideal for doors ranging between 25-150 Kg.

Scissors Arm Door Closers

• It has a double-arm (scissors) where the arms extend and retract to close the door.

• These are ideal for doors ranging between 25-150 Kg.

Electromagnetic Door Closers

These are specialized closers that combine a standard door closer mechanism with an electromagnetic hold-open function. These are commonly used in fire-rated doors and emergency exits, offering the ability to hold the door open under normal conditions and automatically close it when a fire breaks out.

Factors to consider before buying door closers

When buying a door closer, several factors should be considered to ensure that it meets the needs of your space. Here’s a guide on the key factors to consider before buying a door closer:

Budgetary Considerations

The door closer prices vary widely depending on the features, durability, and design. High-end concealed or electromagnetic closers will cost more, while basic surface-mounted closers are more affordable. However, investing in a high-quality door closer can prevent regular maintenance over the years.

Door Weight and Size

The weight and size of your door are major factors in selecting the right door closer. Different closers are designed to handle different door weights. If the door closers do not match the door width, weight, and thickness then the following will happen:

• A door closer that is not suited for the door's weight or thickness may require more effort to open and close. Ozone’s door closers are suitable for doors up to 46 mm thick and 25 to 150 Kg heavy.

• A door closer that is too weak may not be able to close a heavy or wide door completely and can lead to the door being left open. Ozone’s door closers accommodate doors up to 1500 mm wide.

• Using an incorrectly sized door closer will result in frequent repairs or replacements, leading to higher long-term costs.

Mounting Style

Surface-mounted closers

These are installed on the surface of the door or frame. Because they are visible, they are easier to inspect and maintain, which can be particularly beneficial in commercial spaces.

Concealed closers

These are installed within the door or frame to keep the hardware hidden, beneficial in tight spaces. Ideal for hotels, restaurants, and other places where a sophisticated appearance is desired.

Fire and Safety Regulations

Many commercial and industrial buildings are mandated to have door closers that comply with fire safety regulations. If the door in question is fire-rated, you will have to install a closer that meets specific fire and safety standards.

• Fire-rated closers: These closers close doors automatically and prevent the spread of smoke and flames during a fire. Ozone’s door closers are CE and EN 1154 tested, ensuring can withstand high temperatures during fires.

• Electromagnetic door closers: Often used in fire safety applications as they hold doors open during normal operation but automatically close in emergencies. Ozone’s electromagnetic door closers have a smoke detector that raises an alarm during a fire.

Durability

Choose a branded door closer because they often adhere to strict manufacturing guidelines and quality control processes, ensuring durability in their products. Ozone's door closers are tested for 5,00,000 cycles, meaning they can perform consistently for 5,00,000 opening and closing cycles. They are available with warranties ranging from 1 to 10 years, depending on the model.

Adjustable Closing Force

It is typically measured on the EN scale (European Norm). It indicates the force required to close a door and is used to ensure the door closer can be adjusted to match different door weights.

Ozone’s door closers have an adjustable closing force range of EN 1-6:

• EN 1: Suitable for very light doors, typically weighing between 20-40 kg.

• EN 2: For slightly heavier doors, usually weighing 40-60 kg.

• EN 3: Designed for medium-weight doors, ranging from 60-80 kg.

• EN 4: For doors weighing 80-100 kg.

• EN 5: Designed for heavy doors, weighing 100-120 kg.

• EN 6: The highest force level, intended for very heavy doors weighing up to 150 kg.
