The nozzle MX1/4-H may only be used as a room protection nozzle. The nozzle is used for the protection of small rooms or small enclosed objects e.g. EDP-equipment, control cabinets or cable floors. They distribute the extinguishing agent evenly in the extinguishing zone in the calculated flooding time.

In water spray systems
e.g. acc. to VdS 2109
Water spray systems – Planning and Installation The required design bases of the respective object protected by the water-spray systems, such as:
– required design water density or the required operating pressure at the hydraulically most unfavourable nozzle
– protected area
– operating time
must be considered when designing the system.
