An Overview of Biothermic Doors
Biothermic doors, meaning they are gas tight, are considered essential in a variety of building projects, particularly for clients who operate in manufacturing, freight, mining, research or the defence industries.
What Are Biothermic Doors?
Biothermic doors are designed to prevent the flow of gas between rooms or compartments by creating an air tight (gas tight) seal. These specialised doors are built to withstand large amounts of pressure and are made to resist both thermal and chemical damage.
Why Biothermic Doors Are Important
In many operations and industries, the presence or use of certain gases can be harmful to both employees and members of the general public. These gases can also contaminate supplies and equipment, so containing them where necessary is vital.
In these instances, biothermic doors can play a significant role in creating a safer space and keeping operations safe and hazard free. Biothermic doors can:
- Prevent dangerous gases from impacting unprotected people or areas
- Prevent the spread of fire and smoke and assist in containment
- Safeguard sensitive or sterile work spaces
- Prevent machinery from becoming cross-contaminated
Who Utilises Biothermic or Gas Tight Doors?
Gas tight doors have become extremely popular across a wide range of industries for their ability to provide safer and more controllable environments. Biothermic doors are commonly installed in:
- Trains and freight carriages
- Marine and submarine vessels
- 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
How Do Gas Tight Doors Work?
- Seals – Gas tight doors use an inflatable seal to create a barrier impenetrable to gas. A built-in control panel allows the seal to be inflated or deflated with the push of a button
- Locks – Magnetic locks are often used to further improve the effectiveness of the air tight seal on the door, and in many cases locks are used in conjunction with automatic door closing systems
- Monitoring – Viewing windows are often integrated into biothermic doors to enable visual monitoring. Many door models also offer technologically advanced systems that provide real time updates on the conditions on the other side of the door
Biothermic Door Materials
All biothermic doors are designed with maximum durability in mind. The doors and frames are generally made from iron or steel, and the seals are commonly made using silicon, along with a high tech ‘fluoro rubber’ known as FKM or Viton.
Important Door Factors to Consider
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 air tight 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
You’ll also need to take into account how difficult or easy the door installation will be, depending on the location and accessibility of your building or vessel.
