Jokilaakso Hospital is a public hospital located in Jämsä municipality, Finland. The facility operates with a staff of hundreds healthcare professionals who perform thousands of surgeries per year. Jokilaakso Hospital’s fire response times were challenged by lack of night staff and limited resident mobility.

To best protect residents and staff in the event of fire, the hospital needed an active fire protection system. The solution needed to cover several departments, operate independently from the property’s electricity, and consider a limited water supply.

Installation would require a strong expertise, as work would take place under strict hygiene requirements in a constantly operating hospital. The departments in need were retrofitted with the HI-FOG® Gas Pump Unit (GPU), with the bulk of the installations neatly tucked above the facility’s suspended ceilings. The GPU’s two 1500-liter water tanks – and nearly 400 heat-sensitive sprinklers – offer a full hour of high-pressure water mist protection and operate without electricity, eliminating the need for a backup power supply. The HI-FOG uses less water and requires less space for the pump unit than a traditional sprinkler system, the costly structural modifications of adding additional water reserves or large diesel pump units to the building were avoided and indispensable storage space was saved.

" The HI-FOG's solution – the GPU pump unit – needs no electricity, requires little water, and uses small pipes. It proved to be just the right solution for our needs. In addition, the installation went smoothly, meeting our strict requirements for cleanliness and safety in the hospital, which remained in operation throughout." Jari Ihainen, Real Estate Manager, Jokilaakso Hospital.

HI-FOG protects these hospitals also from fire

The Ernst von Bergmann Hospital, Berlin, Germany,  is a future-oriented hospital which focuses on specialized medical services. In Germany it is mandatory to fit fire-rated materials in every escape route which, in this case, would have meant the installation of costly measures such as fire-resistant windows. The HI-FOG system eliminated the need for a number of these procedures without compromising on safety.

The HI-FOG has been installed in many areas of the hospital, including the crucial radiation treatment machines and laboratories, as a part of a renovation.

The Princess Máxima Center Utrecht, the Netherlands, for pediatric oncology wants to offer the best possible care for children with cancer during and after treatment. By combining care, research, education and training in a one national center, the survival and healing opportunities of children are improved, and the quality of life is promoted.

The HI-FOG water mist installation is powered by MSPU7 + 1 pump unit. The protection size is 40 690 m2 in 6 floors. The HI-FOG protects all valuable equipment against fire in the center and safeguards the little patients at the hospital.

In The Máxima Hospital Veldhoven, the Netherlands, the HI-FOG fire protection was implemented with the wet pipe system and deluge system, powered by MSPU05 pump unit.

The deluge system has been applied to protect the generator rooms, where the section valve is closed in standby mode. Opening the section valve (by the fire detection system or manually) causes discharge the mist through all spray heads at the same time and fills the whole space with mist. This way all different parts of the room can be protected from fire. The fire protection area in the hospital is approx. 4,000 m2.

The Central Pori Hospital, Finland, added a new building for newborn intensive care, maternity nursing rooms and patient wards. The HI-FOG system was needed to ensure critical patient and hospital personnel safety by allowing quick evacuation times. The project was a turnkey delivery including the high-pressure water mist sprinkler control system, installation, commissioning, training and a service agreement.
