3 BFZ 1 ½ BETWEEN FLANGE INDUCTORS Document BFZ 1 1-2,/ Ver 1:1 FEATURES Fixed between-flange installation Flow rate up to 480 lpm High back pressure High suction height Suites ARC foams Description The Fomtec BFZ (Between Flange) inductor series represents an extension of the existing line of Z- inductors for fixed use. The BFZ 1 ½ can be used at flow rates up to 480 lpm. Application The BFZ inductor can be installed in all fixed systems, especially in areas where sprinklers are used such as storage facilities and aircraft hangars. Operation The BFZ is installed inside the pipe work between two DN flanges. The BFZ works using the injector principle, i.e. foam concentrate is sucked into the inductor without using a foam pump. Both low and high viscosity concentrates can be used in conjunction with the BFZ. Depending on the requested flow, pressure, foam concentrate type and proportioning ratio the inductor will be equipped with the exact orifice at the entry of the foam pipe. Induction performance and suction height can be adjusted up to a physical limit of approximately 8 meters. Optional The Fomtec BFZ inductor can be customized to handle a variety of flow rates as well as high viscous alcohol resistant concentrates.

4 To get 34% pressure drop over the inductor and get the inductors proper function, the system after the inductor shall have a k-factor that is 27% larger then the k-factor of the inductor when using 3% foam and 30,5 % higher when using 6% foam. If the k-factor on the system after the inductor is less than 22% larger then the k-factor of the inductor the suction ceases completely. If the k-factor on the system after the inductor is more than 27% (3% foam) or 30,5% (6% foam) larger then the k-factor of the inductor the pressure drop over the inductor increases but the flow is constant when you have the same inlet pressure on the inductor.

The WRP allows very accurate proportioning which is constant over the whole flow range. Recommended Foam All types of foam concentrates with induction rates of 1%, 3% or 6% can be used. For ARC (alcohol resistant) foam concentrate a special calibration is made in order to get optimal performance. Operation The Fomtec WRP is installed inside the pipe work between two DN flanges with a minimum pipe length of 5 times the diameter before and after the WRP. The foam inlet is connected to the bladder tank. The operating temperature should be above 0 C. Make sure that the pressure loss over the foam concentrate line from the bladder tank does not exceed 0,3 bar. Key Data The Fomtec WRP BT, wide range proportioner for bladder tanks, offers an exact pre-settled proportioning ratio of 1%, 3% or 6% over a wide water flow range between 70 lpm and 7,000 lpm. The maximum pressure loss is not more than 2.3 bars at 7,000 lpm flow. The foam inlet is equipped with a non return valve to prevent water from going back into the bladder tank.
