The situation is no different when it comes to low-temperature areas, such as freezers or pharmaceutical warehouses. However, not only is information about which types would best fit these types of warehouses scarce, but equipping such rooms with fire sprinklers also presents a series of challenges, such as smoke contamination, low humidity, high ceilings, or a high density of storage.
As such, it is important that warehouse owners make sure to pick the right type of sprinkler for these areas. The most adequate ones are listed below.
Dry Pipe System
A dry pipe sprinkler is the minimum fire code requirement for freezers and pharmaceutical warehouses, and constitutes the most basic solution to the issue of fitting low-temperature rooms with fire protection systems.
Linear Cable Pre-Action System
A pre-action sprinkler, generally activated by a linear heat detection cable, is the industry standard for fire protection in low-temperature areas. This system is designed to avoid accidental discharges, thus ensuring property protection, and is a very economical solution for fire prevention in low-temperature warehouses. They are, however, also rather susceptible to accidents, an aspect which should be taken into account by warehouse managers when making a selection.
Nitrogen-Based Pre-Action System
Nitrogen-pressurised pre-action sprinklers are the safest solution for fire prevention in low-temperature rooms, and considered best practice by industry experts. These systems ensure business continuity in case of a fire alarm, and are built to be sturdy, serviceable and uncomplicated, making them an excellent choice for warehouse owners who value stability over price.
It is clear, then, that the task of installing sprinklers in low-temperature areas, while challenging, is not impossible; it all comes down to knowing which type of system to pick.
