LEADER MIX 2000 foam proportioning system

Fire equipment manufacturer LEADER has launched a new version of its proportioning system: LEADER MIX 2000. With its patented mechanical and automatic mixing system, the new LEADER MIX 2000 is ideal for different fire fighting scenarios, ensuring reliable and optimum operation with low operational cost.

Designed and patented by LEADER’s R&D team, the unique system is based on a venturi system, which achieves an automatic accurate aspiration of foam concentrate required to mix with water. Several fixed mixing ratios, from 0.1% to 6%, are available, which are simple and easy to use, the firefighter simply has to turn a manual selector to immediately set up and adjust the mixing ratio.

The LEADER MIX 2000 is suitable for a wide flow range from 300 to 2000 l/min. It realises real-time adjustment, without human intervention, of current water flow and in case of flow variations. For a large-scale fire, requiring high flow, it is possible to combine several LEADER MIX 2000 systems to increase to even larger flows; for example, by coupling two LEADER MIX 2000s, you achieve flow ranges of 600 to 4000l/min.

The LEADER MIX 2000 can handle all foam concentrate types, including AR-types (wetting-foaming agents, fluorine-free foam concentrate, AFFF, AFFF-AR, proteinic foam, etc ), whether their viscosity: liquids foams (Newtonian fluids) or highly viscous foams (pseudoplastic).

The system’s control panel allows the user to select the intervention position: water, foam or flush. The ‘water’ position (by-pass) reduces pressure loss in the water supply when foam injection is not necessary. The ‘flush’ position allows the dosing system to be rinsed and cleaned for the next operation. The simple interface is easily understandable for fast and flawless action.

As a key part of the foam fire extinguishing system, the LEADER MIX 2000 foam proportioner is a 100% mechanical system, reliable and autonomous. It is stand-alone and is ready to produce foam immediately. It operates without electronics and without an external power supply, unlike electronic foam proportioning technologies. No periodic maintenance is required. The absence of a metering pump increases the reliability of the system and allows dry operation if the end of the tank is reached. This equipment has very low operational cost. All parts and components are corrosion resistant.

This foam proportioning system is suitable for municipal fire and rescue services, as well as for petrochemicals plants, industrial plants, logistics warehouses and waste treatment plants. The LEADER MIX 2000 mixing system can be easily installed in a centralised foam extinguishing system (foam pourer, deluge system, high expansion foam generator etc) or on a fire fighting vehicle in its ‘fixed’ version. In its ‘portable’ version, it can be placed on the ground close to the foam concentrate storage or on remote locations. Its ‘plug and play’ robust construction as well as its extremely compact and light format (less than 35kg) give the system maximum flexibility.
