FireDos ECO: New extremely economical foam proportioner for extinguishing systems

The new foam proportioning systems in the FireDos ECO series have been specially developed for extinguishing systems with high quality requirements, but which require few special features for the proportioner and do not need FM approval or VdS certification. This results in an extremely favourable price, which makes the FireDos ECO devices so attractive for system planners. Another advantage: fast delivery times thanks to sale from stock.

FireDos ECO comprises three different sizes with an extinguishing water flow rate of 300 to 4000 l/min. The proportioning rate is 3%. Like all FireDos proportioners, the devices in the ECO series have a purely mechanical design and are independent of external energy.

Type	Water flow rate	Operating pressure	Proportioning rate
FDE 1000/3	300 - 1000 l/min	Up to 12 bar	3%
FDE 2000/3	600 – 2000 l/min
FDE 4000/3	1000 – 4000 l/min

Best price guarantee: focus on the essentials

In order to be able to offer system planners a high-quality proportioning system at the best price, extensive accessories have been omitted. Only flanges and a flow meter for calculating the proportioning rate are available as optional equipment.

For foam agents with different viscosities

FireDos ECO proportioners are suitable for foam concentrates with a wide viscosity range, as shown in the following table:

Max. foam agent viscosity ¹⁾	shear rate 5 1/s	2700 mPa*s
	shear rate 50 1/s	460 mPa*s
	shear rate 100 1/s	275 mPa*s
	shear rate 600 1/s	60 mPa*s

¹⁾ Foam agents to be used must be below the specified values at all specified points.

Environmentally friendly testing of the proportioning rate

Like the other FireDos proportioners, FireDos ECO enables simple and environmentally friendly testing of the proportioning rate without generating extinguishing foam or premix that has to be disposed of at high cost.

Robust construction

The new FireDos ECO proportioning systems have a robust design for a flow direction from left to right and are designed for an operating pressure of up to 12 bar as standard. Different discharge heights or pulsation do not affect the devices.

Available from stock

To avoid long delivery times, the FireDos ECO proportioners are available directly from stock and can be conveniently requested with just a few clicks via the new FireDos marketplace.
