Pressure differential system for stairwell

System for mantein staireweel free from smoke and to allow people a free and secure go on exodus.

DESCRIPTION

AIR SUPPLY UNIT, integrated into the SPVS system as the FINAL ELEMENT, constructed with a robust extruded
aluminium frame and enclosed with galvanized steel panels insulated with a sound-absorbing mat.
SPVS air supply unit with redundant ventilation.
Flow rate: from 20,000 to 100,000 m³/h
Pressure: 500/800 Pa
Model: GV-SPVS

DESCRIPTION

On the supply side of the GV-SPVS ventilation unit, a special sensor is installed that is capable of detecting smoke particles in the event of a fire. This system quickly triggers an alarm, which can be mounted in a safe location, with a clean contact or through the control panel to stop the machine itself, preventing smoke from spreading inside the stairwell in the event of a fire.

DESCRIPTION

Differential pressure sensor powered and connected to the QE FIRE MODE (24Vdc) to maintain 30 Pa in the stairwell.

DESCRIPTION

The panel consists of the control and command devices for the fans and the safety PLC, which receives the fire alarm from an external system. This allows the Stairwell Pressurization System to be activated autonomously based on the pressure gradients read by the pressure sensors installed in the stairwell. The panel is assembled, tested, and pro-grammed in the workshop, with remote assistance available for programming and technical support to the installer.

DESCRIPTION

The B-CONTROL adjustable diffusers play a crucial role as they ensure the correct air flow distribution to the various floors of the building.

DESCRIPTION

The RELIEF DAMPER ensures that a pressure of 30 to 35 Pa is maintained inside the stairwell. It activates when this pressure range is exceeded, ensuring that doors open easily and providing an effective means of evacuation from the building.
