MODEL FI-PI

Vertical Foam Bladder Tank

Bladder Tank is a large foam liquid concentrate container equipped with a synthetic membrane resistant to abrasive foam materials and a foam proportioner. Bladder Tank is a certified product with a test pressure of 18 bar and a design pressure of 12 bar. Moreover, it can be safely used in temperature conditions ranging from -10°C to +50°C. With its simple mechanism and ability to hold foam bags of different sizes with minimal pressure loss, this product offers a reliable solution for foam proportioning systems. When the foam concentrate is stored in the internal membrane, the tank is used with an internal membrane, while if it contacts the external membrane and is located outside the concentrate container, it is used with an external membrane. Bladder Tank performs foam proportioning using water from the water supply network. Operating with a simple mechanism, the product can hold foam bags of various sizes with minimal pressure loss and can typically be calibrated at percentages of 1%, 3%, and 6%. Compatible with standard or wide-range foam proportioner models, Bladder Tank is an ideal solution for foam sprinkler systems. It stands out for its flexibility, durability, and ease of use.

MODEL FI-WRM

Wide Range Proportioner

Wide Range Proportioner is used to proportion foam concentrate to a water source with a wide flow and pressure range. Incoming water applies pressure to the concentrate in the membrane and carries the pressurized concentrate to the proportioning device. Proportioners have bronze and stainless steel bodies and internals made of 316 stainless steel and measurement orifice. Foam proportioners create a foam mixture to be directed to the distribution network pipes by contacting foam concentrate with water at the desired mixing percentage. These systems are ideal for foam spray systems in fire extinguishing systems. Proportioning devices mounted on the mixer body of the bladder tank maintain mixing accuracy over a wide flow rate range and adjust water and foam sections as the flow changes. There are 2 options among standard sizes and the flow range varies between 100 Lpm and 12,000 Lpm. Proportioners are generally calibrated at %1-%3-%6 ratios.

MODEL FI-PM-UL

Foam Proportioner for Bladder Tank (UL Listed)

The fixed ratio proportioner is designed to maintain a constant ratio of foam concentrate in foam systems. The product is designed for use with low-viscosity foam agents and has a minimum and maximum flow rate ratio range of 1:6. This range can vary depending on the type of foam agent used and specific minimum or maximum flow rates on a given diameter basis. To ensure proper mixing, at least five pipe diameters of straight pipe are required before and after the mixer. The proportioner operates on the principle of reverse pressure and consistently delivers foam from the foam tank or pump to the foam installation through a specified hole diameter. The proportioner ratios the foam at %1-%3-%6 concentrations. Commonly used components include sprinklers, nozzles, monitors, foam makers, and foam chambers. Each fixed ratio proportioner must be accurately calibrated at the factory.

MODEL FI-ML

Inline Inductor (Threaded)

Inline inductors are proportioners that operate with a venturi-type self-induction mechanism. In systems where these proportioners are used, foam concentrate is not housed in a bladder tank but rather in a foam container directly connected to the inline inductor, such as a can, atmospheric tank, etc. Venturi-type inductors mix water from the water source with the foam concentrate to achieve the desired foam mixture. FIERRE manufactures two types of inline inductors: • Model FI-ML for low capacities • Model FI-MLB for high capacities The gear-driven inline inductor model FI-ML is made of aluminum and is available in options with capacities of 200 lpm, 300 lpm, 400 lpm, 600 lpm, and 800 lpm. Optionally, it can also be manufactured from stainless steel, brass, and bronze. Optionally, by adding a mixing valve to the product, users can adjust the foam mixture percentage to be between 3% and 6%.
