The SEM-SAFE® high-pressure water mist system provides reliable fire safety for the historical and valuable pieces in the Vatican library. Picture shows interior of the library. Customer first Our priority is the customers’ needs and ensuring that the project and installation are as smooth as possible. Danfoss Fire Safety provided a full engineering package, including layout drawing, section drawings to understand positioning for piping and assembly details, nozzle layout arrangement, hydraulic pressure drop calculation, detailed mechanical design of the pump room, water tank size specifications and arrangements, BMS low voltage electrical cabling, P & ID drawings, technical description for the system, bill of material and a design, installation, operation and maintenance manual. Key benefits 9 Lowest possible water damage. Clean water is forced through the small-diameter stainless-steel piping network to the SEM-SAFE® nozzles. In contrast to traditional sprinklers, the SEM-SAFE® high-pressure water mist systemuses less water and produces a high level of atomization. 9 100% harmless to people. The technology is safe for people and climate-friendly. 9 The small diameter pipes make the system easy to retrofit, without damaging the building’s structure. 9 Fast system activation in the area where fire is detected, for effective control of the fire. 9 Reliable fire fighting due to excellent cooling properties, including capture of soot particles and reduction of heat. Challenges & smart solutions There are always challenges when planning a new system in a heritage building, where any renovation must be in line with the preservation of the architectural features. In addition, the entire area is “packed” with historic buildings that must not be affected by the work on the library. The stainless-steel pipes used in the SEM-SAFE® system provide a great advantage. The pipes have small diameters. Thus, there is no need to drill big holes in the walls, and they can easily be bent to access any difficult and tight places. The built-in shelves in the library were placed too high, therefore they prevented the original installation plan. The minimum distance between the ceiling and the shelves is 500 mm. To solve this, piping was re-arranged to fit the height of the shelves, while complying with the safety regulations. Small pump unit footprint - great solution for tight spaces Due to limited space in the Vatican Museums, the pump room was built underground in the garden, where careful consideration and care was given to the trees above. With a small footprint and compact design, the SEM-SAFE® pump unit fit easily in the room. Installing the pipe network from the pump room to the protected areas was significantly aided by the flexibility of the small-diameter stainless-steel pipes.
