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.

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.

Construction The Fomtec BFZ 4” inductor consists of a nozzle and a diffusor. The BFZ inductor also allows very accurate proportioning by means of a balance valve which compensates for unforeseen changes in back pressure. Not designed variations of pressure loss due to extra piping or failure of individual sprinkler nozzles will no longer represent a problem. A non-return valve at the entry of the foam pipe prevents water from flowing into the foam container after system is shut down.

The GB 10” FP is designed to work with Foam pumps The foam proportioning can be either pre-set to any value between 1 and 6% or we deliver the GB with a adjustable valve for selection of mixing ratio between 1 and 6%. Foam pressure min 1 bar over water pressure. Please look at table for foam pump selection below. K-factor 1 = 1 lpm @ 1 bar (Q=Kx√P)

WRP 6" BT WIDE RANGE PROPORTIONER
Document Wrp 6 bt / Ver 1:2
FEATURES • Fixed proportioning ratio
1%, 3% or 6% • Water flow 70 - 7,000 lpm • Between flange
construction • Suitable for ARC foam
concentrates • Easy to install
Description The Fomtec WRP 6” BT is suitable for fixed foam systems where a variable flow rate can occur, such as in sprinkler systems or multiple deluge systems. 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.

Application Fixed foam systems where a variable flow rate can occur, such as in sprinkler systems or multiple deluge systems.
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 necessary and should be mentioned when ordering.
Operation The WRP can be installed horizon-tally or vertically with a minimum pipe length of 5 times the diameter before and 3 times 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. The proportioning ratio is constant over the whole flow range.
Key data The Wide Range Proportioner, WRP, for bladdertanks offers an exact pre-settled proportioning ratio of 1%, 3% or 6% over a wide water flow range between 200 lpm and 15000 lpm. The maximum pressure loss is not more than 2,8 bars at 12000 lpm flow. The foam inlet is equipped with a non-return valve to prevent water from going back into the bladder tank.
