Foamtronic VFD system

The FoamTronic VFD is an electronic foam mixing system which  accurately mixes foam concentrate and water, based on the actual firewater demand of the system.

The FoamTronic is designed to cover a wide range of foam system demands.

Test without mixing

To comply with the NFPA 11 standard, the operation of a foam extinguishing system must be tested annually with a live test. A large amount of foam concentrate is used for this test. This is not only harmful for the environment, but also expensive for the owner. It is not only the purchase value of the foam concentrate, but also the additional  costs as the foam must be collected, and disposed of correctly to satisfy the environmental requirements.

The FoamTronic VFD system is NFPA 11 compliant and can be tested without the need of mixing firewater and foam concentrate. The system can be supplied as either individual components or as shown below.

High precision proportioning

The accurate mixing of foam concentrate and water is achieved by the continuous monitoring of the firewater and foam concentrate flows, using electromagnetic flowmeters and a real-time adjustment of the speed of the foam pump. The accuracy and stability of the system is based on the combination of specially selected components and a unique control system with state-of-the-art logic developed specifically for FoamTronic.

The control system records all process values and alarms during operation or test which are available via a simple user friendly interface. When compared to a traditional mechanical proportioner the user has the added benefit of being able to save money on the foam usage due to the high accuracy of controllable consistent proportioning.

SYSTEM START

The foam mixing system can start either based on minimum measured waterflow, an external command from the fire alarm control panel or the combination of the two.

SELF-DIAGNOSTICS

The VFD Foamtronic continuously monitors the following:

  •  Power available;
  • Condition of flow meters;
  • Condition of frequency drive;
  • The PLC

SYSTEM BACKUP OPTION

The system has the option to communicate with and control a 2nd Foamtronic system. This can further increase operational reliability.

SYSTEM CAPACITY

Due to the ability to control the speed of the foam pump the system has a very wide wor-king range. The maximum water pressure can go up to 16 bar.

The table below shows the working ranges of the standard model.

The table is based on the following parameters:

  • 10 - 16 bar outlet pressure;
  • 3% foam mixed at 3.1%
