The Germany-based company FireDos has turn into an established specialist within the field of designing and manufacturing high-quality foam proportioners and screens for firefighting worldwide.
“About 20 years in the past, we had been the first company to develop a proportioning concept for firefighting which includes a water motor and a piston pump,” says Managing Director Frank Preiss, portraying the company’s early days. This concept became established in the subject of firefighting very quickly. The firm FireDos produces stationary proportioners for industries like oil/chemistry, automotive and logistics in addition to for fireplace brigades. Product approvals such because the Europe-wide VdS accreditation or the international FM approval which was achieved in 2008 verify the company’s very high product commonplace. The testing facility installed at the Woelfersheim premises is exclusive all through Europe, too, because it permits testing of proportioners and displays at water circulate charges of as much as forty 000 liters per minute (10 566 gpm).
One of the FireDos proportioners’ most outstanding traits is the power of testing the proportioning rate with out generating foam or premix. “Particularly this eco-friendly and cost-saving testing of the proportioning price is a good aggressive benefit. In addition, we function-test all units earlier than supply to be able to assure the very best stage of quality,” says Frank Preiss. This concentrate on quality and setting is an integral part of the company philosophy and also exhibits in the merchandise themselves.
Many hearth scenarios may be tackled efficiently and successfully provided that foam is used. In order to produce such foam, a foam focus should be admixed to the extinguishing water at high precision. “What makes ไดอะแฟรม ซีล is that our custom-made water motors and piston pumps work in proportional ratios. This makes the admixing exact, no matter what the water flow fee, pump strain and extinguishing agent’s viscosity is. This method, we always stay inside the tolerance necessities of worldwide regulations for foam proportioning,” informs Ingo Weiss, Sales Manager. Further benefits of this technique embrace its straightforward operation and independency of electrical energy, pushed simply by the extinguishing water flow. As Weiss stated, the hearth departments of several major German cities chose the FireDos system simply due to that. The subsequent generation of proportioners, which is extra compact, lighter and optimized in nearly all efficiency relevant traits, is at present undergoing approval testing and will enter the market by the end of 2019.
Fire Monitor Experts

In 2013, screens for firefighting were added to the company’s product portfolio. Designed by FireDos this new improvement doesn’t only make a visual distinction to competitors’ equipment. “We took new paths in performance and design,” says Preiss. The octagonal ‘Oval Flat Design’ permits a good circulate profile with minimized turbulence, resulting in solely very low stress loss. The extinguishing agent jet can due to this fact obtain an prolonged attain. The portfolio is on the market with circulate rates of up to 60 000 liters per minute (15 850 gpm) and a variety of a hundred and eighty meters (590 ft). Optional it allows a steady adjustment of the water circulate rate during operation. The monitors could be actuated either manually or electrically. “This makes them an all-rounder in firefighting and match for particular person adaptation to essentially the most variable fields of operation,” reviews Weiss. Handling is simple, too. Only little force is critical to swivel the monitors. This helps the operator in the guide version simply as it is to the good factor about the drives within the remote-controlled version since the power consumption stays low. Such elements which are exposed to the extinguishing agent move are designed to face up to a testing strain of 64 bar (928 psi), which makes them extremely sturdy and fit to handle sudden loads.
“We concentrate on our stationary proportioners, hearth brigade systems and fire-fighting monitors to remain market-leading experts in these fields. We are strengthening our service capabilities to offer our clients an all-round worry-free package deal,” states Preiss. And efficiently so: ไดอะแฟรม and more industrial companies and fireplace brigades depend on the merchandise made by FireDos.
