Optional features / Items

Water flow direction configuration

Reversed flow (Right to left) or Vertical flow direction (upwards or downwards). Standard flow direction is from left to right seen from pump.

Dosing/Return valve (DRV)

Valve for returning the concentrate to the tank, making it possible to check the functioning of the unit and to measure the admixture rate with suitable equipment (see below), without generating water/foam solution. Including a Pressure relief valve (PRV) to avoid over-pressure, in case the return line is blocked for discharge for any reason.

DRV dosing rate measuring equipment

Measuring equipment consisting of one mag flow meter for water flow, one mag flow meter for pumped concentrate and a pressure regulating valve for simulating working pressure in return line.

Customized Water motor connections / Add-on Couplings

Flanged connections, Threaded connections / Grooved flange adaptors, Storz couplings, etc.

These can be add-on adaptors, or integrated in the design as our modular concept allows to customise the water connections.

Y-strainer

If the firefighting water contains foreign/solid particles a strainer in the main water line before the FIREMIKS is a necessity. Threaded strainer in SS up to DN 100 - G 4" and Grooved or Flanged strainers in Painted Ductile Iron from 2" up to 12" in ANSI or DIN Standard.

Actuators

Electric or pneumatic actuators can be specified and mounted according to specifications.

Handheld Tachometer for RPM measurement

Used to give an estimate of the water flow through the water motor and to compare with max flow rpm stated on this Data sheet, to ensure that unit is not over-speeding, especially at start-up (see Instruction Manual). Note: RPM cannot be used to correctly verify the dosing rate as the actual unit flow performance is not verified with this method.

Certifications / Factory Acceptance tested (FAT)

Each unit is FAT tested as standard. Each unit can be Factory Acceptance tested (FAT) or delivery inspected according to applicable parts of NFPA 11 or EN 13565, by DNV (Det Norske Veritas) or other third party inspectors.
On special request, type testing can be done for specific markets.

Material certificates EN 10204

Depending on availability, material certificates for the water motor materials and some other parts can be provided if specified when ordered.

Supervisory switch

1NC+1NO switch on the Dosing / Flushing valve, allowing remote confirmation that the valve is in the dosing position. Also available on the optional DRV valve.

Higher spring rate in check valve in internal dosing line

To avoid leakage of concentrate in dry pipe or non-pressurised water pipe systems in combination with gravity feed.

Check valve on internal flushing line

To avoid leakage of concentrate in dry pipe or non-pressurised water pipe systems, if wrong handling of the Dosing / Flushing valve occurs.

Higher-grade stainless-steel piping

Specially made piping parts in higher grade SS.

High temperature application above 55°C (131°F)

Unit adapted with materials for usage up to 80°C (176°F). Relevant low temperature performance may be affected.
