Not sure what exactly a DLP System is? Or if you or your company needs one?

We’ve answered some of your questions below to educate you to help you make an informed decision.

What is a Direct Low Pressure System?

A Direct Low Pressure System is a specialist fire suppression system that has been specifically designed to protect small enclosures such as single Server Racks, Electrical Control Cabinets and Electrical Switch Gear Cabinets.

Small electrical cabinets can present a significant fire hazard at any time as they are usually an enclosed unit located within unmanned areas of a building, and this is what makes the DLP systems so effective, as they have been designed to detect and extinguish a fire rapidly, preventing damage to equipment and further spread of fire.

How Does a Direct Low Pressure System Work?

A Direct Low Pressure System has a simple, fully automatic operation. A storage tank is fitted containing the extinguisher agent. Pressurised tubing is then strategically fitted across the whole area to ensure maximum coverage. If a fire starts, the flames or high temperatures shall burst the piping, discharging the extinguisher agent only onto the area of detection.

These systems are specifically designed to meet all relevant certification, especially Loss Prevention Started, LPS 1666.

A typical installation design.

Where Would a Direct Low Pressure System Be Used?

Direct Low Pressure Systems are suitable for protecting sensitive electrical equipment, which is why they are often used in commercial buildings, industrial units such as warehouses, and healthcare facilities. In particular, they are commonly found within Electrical Control Cabinets, Electrical Switchgear Cabinets and Single Small Server Racks.

If you are worried about the possible effects of data loss or damage to equipment, and the impact it could have on your business, a DLP System could alleviate those worries, as their direct and clean suppression helps stop the spread of fire and protects the electrical equipment.

Does a Direct Low Pressure System Require Power?

No, a Direct Low Pressure System does not require a power supply for it to work. Once the system is installed, it activates automatically if the pressurised tubing is ruptured by the flame or temperature.

This means that if your building loses power in the middle of an emergency, you can have some peace of mind that your suppression methods will still be fully functional.

Is a Direct Low Pressure System Eco-Friendly?

Yes, Direct Low Pressure Systems are environmentally friendly. They use an electronically non-conductive clean agent which, if discharged, does no damage to the electronic equipment or the data stored on it, and it has zero ozone depleting potential, and negligible global warming potential. These agents also comply with regulatory standards, always ensuring safe practice.
