When it comes to door closers, the choice between hold open and non-hold open models can significantly impact the functionality and convenience of a space. Door closers are essential devices that ensure doors close securely and smoothly, but the decision to use a hold open or non-hold open model depends on various factors, including the intended use of the door, the frequency of traffic, and specific safety requirements. This article will delve into the differences between hold open and non-hold open door closers, exploring their features, benefits, and potential drawbacks to help you make an informed decision.

Functionality and Mechanism

Hold open door closers are designed to allow doors to remain open at a specific angle, typically 90 degrees, until they are manually closed. This feature is particularly useful in high-traffic areas where doors need to stay open for extended periods, such as in hospitals, schools, or office buildings. The mechanism behind hold open door closers involves a hydraulic or pneumatic system that can be adjusted to hold the door at the desired angle. When the door is pushed beyond this angle, the closer engages and begins to close the door smoothly.

On the other hand, non-hold open door closers do not have the capability to hold the door open at a specific angle. These closers are designed to close the door immediately after it is released, ensuring that the door is always securely closed unless manually held open. This type of closer is often used in areas where security and energy efficiency are priorities, such as in residential buildings or storage rooms. The mechanism in non-hold open door closers is simpler, relying on a spring or hydraulic system to close the door without any hold-open feature.

Applications and Use Cases

Hold open door closers are ideal for environments where doors need to remain open for extended periods to facilitate the flow of people or equipment. For example, in hospitals, hold open door closers are often used in corridors and patient rooms to allow easy access for medical staff and equipment. Similarly, in office buildings, these closers can be used in conference rooms or break areas where doors need to stay open during meetings or gatherings. The ability to hold the door open at a specific angle ensures convenience and accessibility in these high-traffic areas.

Non-hold open door closers, however, are better suited for areas where security and energy efficiency are more critical. In residential settings, non-hold open door closers are commonly used on exterior doors to ensure that they are always securely closed, preventing unauthorized access and maintaining indoor temperature. In commercial settings, these closers are often used in storage rooms, server rooms, or other areas where it is important to keep the door closed to protect valuable assets or sensitive information. The immediate closing action of non-hold open door closers helps maintain security and energy efficiency in these environments.

Safety and Compliance

Safety is a crucial consideration when choosing between hold open and non-hold open door closers. Hold open door closers can pose a safety risk in certain situations, such as in fire-rated doors where the door must close automatically in the event of a fire. To address this, some hold open door closers are equipped with a fire safety feature that releases the hold-open mechanism when a fire alarm is triggered, allowing the door to close and contain the fire. It is essential to ensure that any hold open door closer used in a fire-rated door complies with local fire safety regulations.

Non-hold open door closers, by design, do not have a hold-open feature, which makes them inherently safer in fire-rated applications. These closers ensure that the door is always closed, providing a barrier against the spread of fire and smoke. In addition to fire safety, non-hold open door closers also help prevent accidents by ensuring that doors do not remain open and obstruct pathways, which can be a tripping hazard. For these reasons, non-hold open door closers are often the preferred choice in environments where safety is a top priority.

Maintenance and Durability

Maintenance requirements and durability are important factors to consider when selecting a door closer. Hold open door closers, with their more complex mechanism, may require more frequent maintenance to ensure that the hold-open feature functions correctly. The hydraulic or pneumatic system in these closers can be prone to wear and tear over time, especially in high-traffic areas where the door is frequently opened and closed. Regular lubrication and adjustments may be necessary to maintain the performance of hold open door closers.

Non-hold open door closers, with their simpler mechanism, generally require less maintenance. The absence of a hold-open feature means there are fewer moving parts that can wear out or malfunction. This makes non-hold open door closers more durable and reliable in the long run, especially in environments where the door is used frequently. However, it is still important to perform regular maintenance, such as checking the spring tension and ensuring that the closer is properly aligned, to ensure optimal performance and longevity.

Cost and Installation

The cost of hold open and non-hold open door closers can vary depending on the brand, model, and features. Generally, hold open door closers tend to be more expensive due to their additional functionality and more complex mechanism. The installation process for hold open door closers can also be more involved, requiring precise adjustments to ensure that the hold-open feature works correctly. This may result in higher installation costs, especially if professional installation is required.

Non-hold open door closers, being simpler in design, are typically more affordable and easier to install. The installation process is straightforward, and adjustments are minimal, which can help reduce installation costs. For those on a budget or looking for a cost-effective solution, non-hold open door closers may be the more attractive option. However, it is important to consider the specific needs of the environment and the intended use of the door when making a decision, as the initial cost savings may be outweighed by the benefits of a hold open door closer in certain situations.

In conclusion, the choice between hold open and non-hold open door closers depends on a variety of factors, including functionality, application, safety, maintenance, and cost. By carefully considering these factors, you can select the door closer that best meets the needs of your space, ensuring convenience, security, and safety for all users.
