märkajärjestelmä

Märkajärjestelmä is a Finnish term that translates to "wet system" or "moist system." It refers to a type of sprinkler system designed to protect areas where the risk of fire is moderate. In a märkajärjestelmä, the piping throughout the entire system is filled with water at all times. When a sprinkler head activates due to heat, water is immediately discharged onto the fire. This contrasts with dry pipe systems, where the pipes are filled with compressed air and water is only released once the air pressure drops.

The primary advantage of a märkajärjestelmä is its rapid response time. Because the pipes are already pressurized with water, the delay between activation and water discharge is minimal, making it highly effective for controlling fires quickly. These systems are commonly installed in buildings where freezing temperatures are not a concern, such as commercial spaces, offices, and some residential buildings. They are a reliable and cost-effective solution for fire suppression in suitable environments.

Regular inspection and maintenance are crucial for the proper functioning of any märkajärjestelmä. This ensures that all components, including sprinkler heads, valves, and alarms, are in good working order. The system's design and installation must adhere to relevant fire safety codes and standards to guarantee its effectiveness in the event of a fire.
