A guide to biothermic doors
Biothermic doors create a gas-tight seal, which work to prevent the flow of gas between various rooms or compartments, withstanding significant amounts of pressure, as well as high temperatures and chemical damage.
Biothermic doors are an essential safety measure for a diverse range of industries. Read on to find out how they work, as well as whether you need them in your building.
How do they work?
When it comes to biothermic doors, durability is essential, so frames are generally constructed from high-quality iron or steel, with the seals made using silicon and a high tech ‘fluoro rubber’ known as FKM or Viton. Furthermore, they function via their seals, locks and monitoring systems.
Seals: Biothermic doors create an inflatable seal to form a barrier against gas. The pressure of the seal is controlled with a built-in control panel.
Locks: The seal is further improved with magnetic locks, which are in most cases used in conjunction with automatic door closing systems.
Monitoring: Most gas-tight doors are equipped with viewing windows built into their structure, which allows for visual monitoring. Other inbuilt sensors can provide real-time updates on the sealed process, depending on the specifications and industry.
Why are they important?
In many industries, biothermic doors are essential for safe operation, preventing harmful gases from contaminating supplies and equipment, as well as preventing people from these risks. Furthermore, they can contain fire and smoke and safeguard fragile, sensitive or sterile work environments.
Who needs them?
Biothermic doors are essential across many industries such as:
• Oil, gas, mining and offshore facilities
• Energy and civil engineering plants
• Medical, pharmaceutical and scientific laboratories
• Processing plants
• Waste management and treatment facilities
• Military buildings
• Storage facilities
• Atomic/nuclear power plants
If biothermic or gas-tight doors are required for your design or upgrade project, you must ensure that your chosen doors:
- Are certified and comply with BCA regulations (ASxxx) in relation to their airtight properties, as well as any other performance requirements (such as fire protection, acoustic insulation etc.)
- Can operate as desired; i.e. do you require a hatch door, sliding door or a double-action swinging door?
- Have been designed to meet your specific needs; note that gas-tight doors vary considerably in terms of their ability to deal with a range of temperatures, gases and chemicals, so you’ll need to select the doors that will provide you with the required level of protection.
