With PVProtect, Minimax presents a brand new water-based fire suppression system at the VdS-FireSafety Cologne: The holistic protection concept for roof surfaces with photovoltaic systems is the first of its kind on the market that is VdS-approved.

Roofs containing flammable insulation materials pose significant risks. Even small fires on roof constructions can lead to severe business interruptions and loss of sales. PVProtect helps to significantly reduce or even entirely prevent such damages. The system offers protection against fire hazards on roof surfaces with an incline of up to 10° on which photovoltaic systems have been installed. Consequently, Minimax is the first fire protection company to offer a solution for such previously unprotected environments.

The first water-based fire suppression system of its kind – early detection combined with automatic fire fighting

The holistic protection concept combines early detection with automatic fire fighting. By preventing fires on the roof, PVProtect, thus, can also protect the entire building against consequential damages; in addition, it alerts people on site in good time.

Heat detectors are arranged in a targeted manner around the photovoltaic modules. In case of an unusual rise in temperature, the detectors pass on the information to the fire detection and extinguishing control panel, which simultaneously alerts the fire department. The close-meshed arrangement of sensors makes it possible to precisely locate the source of fire. Extinguishing nozzles are arranged in the vicinity of the photovoltaic modules to ensure water coverage over the entire area. In this way, PVProtect automatically fights incipient outbreaks of fire before they spread widely.

Efficient water consumption, easy to retrofit – VdS-approved

Special extinguishing nozzles ensure a risk-appropriate distribution of water even at low operating pressures. Localization of the source of fire in conjunction with a suitable extinguishing control system and effective area distribution allow for water requirements to be further reduced, while also reliably keeping fire hazards under control.

Because of the minimal water requirements and low operating pressures, PVProtect can usually be connected to the existing water supply of a sprinkler system. Integration into an existing fire protection system is, therefore, cost-effective and uncomplicated.

The effectiveness of PVProtect has been evaluated in fire tests and approved by VdS Schadenverhütung. The VdS approval applies to both the system and the individual components. PVProtect, thus, provides a basis for making the building insurable again.

First-time presentation at the VdS-FireSafety Cologne – presentation included

Minimax exhibits the new PVProtect fire suppression system for the first time at the VdS-FireSafety Cologne on December 6th–7th, 2023 at booth D-07 in hall 10.1.

The prize is awarded in four categories: "Innovation", "Fire protection", "Fire protection management" and "Special locations". The Security Oscars have been the benchmark event for the fire protection sector in France for more than 20 years. This year, Minimax France competed in the "Innovation" category.

The awards were presented to the laureates on November 13, 2023 by Mrs. Dominique Faure, Minister Delegate for Local Authorities and Rural Areas, during a festive ceremony at the Palais du Luxembourg.

Pascal Bichet, Country Manager Minimax France, said about the award: “Minimax France is very proud to have received this award, especially since we were recognized by our industry colleagues.”

The award-winning Minimax high-performance firefighting turbine MXOne – Next generation firefighting

The Minimax MXOne en­ables in­nov­at­ive fire pro­tec­tion using highly ef­fi­cient water mist from a safe dis­tance. Thus, it rep­res­ents a new gen­er­a­tion of stationary fire­fight­ing sys­tems. It al­lows highly ef­fi­cient, pre­cise and tar­geted sup­pres­sion from a sig­ni­fic­ant and safe dis­tance. The tur­bine achieves a large dis­charge range thanks to the ad­justable jet pipe, even when using a foam agent.​

Dur­ing a fire, the water mist ab­sorbs a huge amount of en­ergy, cools par­tic­u­larly ef­fect­ively and reaches hid­den fire sources due to the three-di­men­sional mode of ac­tion. It binds smoke gas, pol­lut­ants and odors and can quickly de­velop its ef­fect over large areas without, like clas­sic mon­it­ors with their fo­cused jets, dis­pers­ing burn­ing ma­ter­ial and pos­sibly con­trib­ut­ing to the spread of fire.

Further information on the MXOne to be found here.

As part of the RWM DIGITAL SERIES, a digital format of the leading trade fair for recycling, materials and waste management, on 20 May Jan Weimann (Minimax) introduces Minimax's high-performance firefighting turbine MXOne. He will show video footage of extinguishing tests in our Fire Protection Research Center. During the lecture and afterwards you can ask questions via chat.

Certain remote, hard to reach or large areas in the industry, energy or infrastructure sector cannot be covered in an efficient or economical way by conventional fire protection systems. MXOne uniquely meets the demands posed by special fire risks in numerous industry and risk areas, both inside and outside buildings – incl.: Recycling operations, Wood-processing industry, Chemical plants/refineries, Airports/hangars, Substations/transformers.

Today, Minimax is launching the extinguishing turbine MXOne. This unique system has a 360° operating range and enables the highly precise application of water mist from a significant and safe distance. In the event of a fire, the water mist absorbs a huge amount of energy, cools particularly effectively and reaches hidden fire sources better than classic monitors. It binds flue gases, pollutants and odors, and is able to exert its efficiency quickly over large areas. The effectiveness of the turbine has been examined and confirmed in full-scale fire trials conducted by independent bodies, including DMT.

MXOne can be operated with potable water, seawater and with/without foaming agents. Spray patterns can range from a fine water mist to a full jet. The firefighting system reaches a flow rate of up to 4,000 liters per minute. MXOne can be aimed at a hot spot either fully automatically or manually via remote control. Thanks to a smart operating system, a single turbine can supply water alternately to two or more neighboring areas. Consequently, several fires can be fought in parallel, or nearby facilities threatened by fire can be specifically cooled in a targeted manner. The turbine can be easily integrated into existing plants and is suitable for use in areas with temperatures ranging from -15°C to +55°C.

A decisive innovation: throw distance
MXOne has the unique ability to fight a fire with water mist from a significant distance. The turbine is able to offset the susceptibility of small droplets to external factors such as crosswinds or headwinds using a smart control system and activating a supporting air stream. Furthermore, the system can be flexibly adapted to meet almost any challenge posed by different fire scenarios.

Efficient firefighting with water mist
When extinguishing a fire with water mist, the water is atomized under high pressure, meaning the smallest of water droplets and a larger reaction surface are formed that absorb heat. When water evaporates, its volume is increased many times over, thus displacing the oxygen at the source of the fire. The smothering effect fights the fire directly. The cooling aspect of the water mist protects people and property from the effects of heat. The volume of water consumed during the firefighting effort as well as the consequential damage caused by the water are extremely low.

Maximal flexibility in positioning and application
The control and direction of the extinguishing turbine can be done fully automatically, as follows: Information from at least two fire detectors (e.g. UniVario industrial fire detectors or infrared cameras) is assessed in the fire alarm and control panel and the location of the source of the fire is accurately determined before MXOne is activated. Alternatively, manual control of the turbine is always an option. Both stationary and mobile control variants can be implemented according to the operator's requirements.

More details

The UniVario YMX5000 series offers new possibilities in spark detection in the wood-processing industry: for the first time there is a cyclic optics monitoring of all sensor units, as well for spark detectors. A new feature is that this detector series is suitable for extreme temperature ranges, and thanks to its modularity offers maximum flexibility in use.

The detection system of the UniVario YMX5000 series consists of a control unit with three connectors for remote sensor units. The electronics of the evaluation unit is self-monitoring, displays for example alarms or faults, and thus offers extra functional safety. The sensor units are connected to a control unit and allow dependable detection wherever there is an increased fire risk from sparks. The spark detection system is audited and approved by VdS.

New standards for additional safety: Self-monitoring in spark detection

Self-monitoring of optics has since become standard in flame detection. The UniVario YMX5000 system has succeeded for the first time in the world in transferring this standard to spark detection. At cyclic intervals the optics are monitored with regard to contamination or damage - a functionality that again significantly increases the operation safety of the system in the sometimes harsh areas of deployment in a wood-processing plant.

Extreme temperatures: From ice-cold to hot

The UniVario YMX5000 system is suitable for applications in extreme temperature ranges. The corresponding FUX sensor unit can even be used without fiber optic adapter at temperatures from -40°C to 105°C. The sensor units will be also available in an “Ex” version for use in explosion-hazard zones in Ex zones 1, 2, 20, 21 and 22.

Minimal downtimes: Easy, secure and long-lived system

Installing the sensor units is simple and safe thanks to the single-hole mounting with bayonet locking. The flush wall connection within transport- or suction channels minimizes the wear of the optics and guarantees a long lifetime. Possible air flushing does not affect the 120 degree viewing angle of the sensor system. Maintenance, for example for defective optics, is particularly easy thanks to a quick-change replaceable optics, so downtimes can be reduced to a minimum.

Minimax will be displaying the new UniVario YMX5000 detection system as a world first on the occasion of LIGNA 2017. In addition to this visitors to the Minimax trade stand at LIGNA can find out more about Minifog PressProtect, a solution for the protection of industrial presses, DryerProtect, the combined fire detection-, water mist- and spark extinguishing technology for driers, thermography systems and the Inveron hazard management system.

In the VN nozzle the screens are not a fixed component of the product. Depending on the extinguishing agent throughput required, an appropriate screen is only inserted during installation. For subsequent changes in the performance requirement only the screen needs to be changed, not the entire nozzle. This makes the VN nozzle an extremely flexible and economic solution.

At Booth B43 in Hall 12 of our partner CANCOM, professionals can take a look at the Minimax fire protection solutions for the digital economy. In a mobile data center (IT container), Minimax employees from Würzburg demonstrate a fully functional MX 1230 extinguishing system with a FMZ 5000 mod 4 fire detection and extinguishing control panel. In addition, a HELIOS AMX 5001 aspirating smoke detector is installed in the container.

Also available is a OneU fire protection system, which was developed for installation in closed 19" racks. In this case, the system is mounted in a BIG IT shelter.

The OneU fire protection systems are characterized by highly sensitive fire detection and residue-free extinguishing. A high level of data availability is ensured by redundant components and an integrated emergency power supply. OneU systems offer maximum flexibility due to modular expansion capability. Conventional fire protection systems require up to three height units in the rack. Thanks to its unique installation height of only one height unit (44 mm), OneU fire protection systems, on the other hand, leave much more space for the IT components in the expensive racks. At the same time, the OneU system is equal in function, quality and reliability to systems that need more space.

OneU fire protection systems guarantee maximum availability of technical equipment even in the event of short circuits, overloading, overheating or component error causing an incipient fire. They are an ideal component for availability concepts, such as:

Server and network technology, which ensures 24/7 availability of essential company data,

production controls, which control and monitor production processes,

telecommunication installations, which ensure fault-free, smooth communication throughout the company.
