HDFIRE – Retard Chamber

Description

About Hdfire Retard Chamber

HDFIRE Retard chamber is an essential component in fire sprinkler systems, particularly in dry pipe sprinkler systems. Its primary function is to introduce a controlled delay in the activation of sprinkler heads, allowing sufficient time for water to flow through the piping and reach the open sprinkler heads in the event of a fire. In dry pipe sprinkler systems, the piping is filled with compressed air or nitrogen instead of water. When a fire occurs and a sprinkler head activates, the air pressure is released, allowing water to enter the piping and flow to the open sprinkler head. However, there can be a delay between the activation of the sprinkler head and the arrival of water due to the need to purge the air from the system. The retard chamber is strategically placed in the system to create a temporary reservoir where air is trapped, causing a delay in the release of water. This delay ensures that sufficient water pressure builds up in the piping before reaching the open sprinkler head, preventing premature discharge and optimizing the system’s effectiveness in suppressing fires. Retard chambers are typically constructed from durable materials such as steel or brass and are designed to withstand the pressures and demands of the fire protection system. They undergo stringent testing and certification to ensure reliable performance and compliance with industry standards and regulations.
