STAIRCASE OVERPRESSURE KIT
- Staircase overpressure kit comprised of a control panel (BOXPRES KIT) and impulsion units (CJHCH or CJBD), for pressurising staircases and escape routes. Also available for NEOLINEO AND CJBC single-phase equipment.

OVERPRESSURE KIT WITH RESERVE FAN
- Overpressure kit with reserve fan comprised of a control panel (BOXPRES KIT II) with a built-in automatic switching system that maintains the overpressure in the event of a failure in the main fan and air impulsion units with a TWIN or CJHCH/DUPLEX series reserve fan.

BOXPRES
- The correct operation of the pressurization systems depends not only on their sound design, but also on the correct regulation performed by the system. For this reason, it is extremely important to have calibrated, high precision regulation elements that will permit both situations present in the event of a fire to be maintained simultaneously, quickly and stably.
- The BOXPRES control panel not only complies with the strictest requirements, it simplifies the work for the installer.

It includes:
- A frequency changer programmed at 50 Pa.
- A differential pressure probe.
- A magnetothermal switch.
- A line and failure led lamp.
- A check push button.

All the BOXPRES equipment interconnections have been made and tested.
- Ready to operate and execute its function of controlling the installation pressure.
- Option of checking the installation to prevent failures.
- Only the power supply line, impulsion fan and fire signal need to be connected.

The single-phase panels include:
- A voltage adjuster programmed at 50 Pa.
- A differential pressure probe outside the equipment.
