Foam System

سیستم‌هـای فـوم

فوم آتش نشانی ترکیبی از آب و ماده فوم می باشد که معمولاً پس از ترکیب آب و مایع فوم می بایستی به خوبی هوادهی شود تا مخلوط فوم منبسط شود.
شرکت ساختار انرژی ژرف به عنوان نماینده انحصاری شرکت Sabo اسپانیا در زمینه تجهیزات فوم فعالیت می نماید.

سیستم‌های فـوم

سیستم های اطفاء حریق بر اساس فوم معمولاً برای مواد کلاس B مورد استفاده قرار می گیرد. در ایران طراحی این سیستم بر اساس استاندارد NFPA صورت می پذیرد. فوم آتش نشانی ترکیبی از آب و ماده فوم می باشد که معمولاً پس از ترکیب آب و مایع فوم می بایستی به خوبی هوادهی شود تا مخلوط فوم منبسط شود. نسبت ترکیب آب و فوم به قرار زیر می باشد:

%1 مایع فوم + %99 آب : برای اطفاء حریق کلاس A

%3 مایع فوم + %97 آب : برای اطفاء حریق مواد نفتی

%6 مایع فوم + %94 آب : برای حلالها و مواد الکلی

بر اساس مقدار توسعه و انبساط فوم تقسیم بندی زیر صورت می گیرد:

فوم کم توسعه (Low Expansion Foam )

فوم میان توسعه (Meduim Expansion Foam )

فوم پرتوسعه (High Expansion Foam )

Bladder Tank

The Bladder Tank is an essential part of the Bladder Tank Proportioning System. They require no external power, other than a supply of water to ensure proper operation. The Vertical and Horizontal Bladder tanks are designed and constructed in accordance with the latest revisions of ASME code Section VIII for unfired pressure vessels.
They have a working pressure of 12 bar and they are tested to 17.2 bar. Used with a ratio controller, this system is designed to inject foam concentrate into a suitable water supply and to automatically proportion foam concentrates over a wide range of flows and pressures.

  • Type: Horizontal or Vertical
  • Max. working pressure: 12 bar
  • Body material: carbon steel ASTM A 516 gr.70
  • Available Size: Project Requirement

سیستم‌های فـوم

Foam Dosing

Foam Dosing are particularly suited for use in systems with low start flows, for example sprinkler systems. They require no external power.
Piston pumps are also very suited for low and medium viscosity concentrates. The unit shall be placed in such a manner that the concentrate has a free flow down from the foam tank to the dosing pump.
A typical fixed installation with a Piston pump model is often where a customer prefers the characteristics of Piston pumps, use low to middle viscosity concentrates and work on a wide flow range. The unit shall be placed in such a manner that the media concentrate has a free flow down from the tank to the dosing pump.

  • Min. / Max. working pressure: 4 bar /12 bar
  • Body material: Aluminum / Bronze
  • Available Size: 180 Lpm ~ 8000 Lpm

Foam Chamber

Foam Chamber is designed to discharge expanded foam directly onto the surface of a flammable or combustible liquid for fire extinguishment. Classified as a Type II discharge device in accordance with NFPA Standard 11, foam chamber delivers low expansion foam directly onto the fuel surface. Minimizing submergence and agitation increases the effectiveness of the foam blanket, resulting in more efficient operation, and superior extinguishing capabilities.
Foam Chamber is used in one of the most common applications to protect vertical fixed roof (cone) liquid storage tanks, with or without internal floating roof with the low expansion foam system

  • Application: Foam Solution, 1%, 3%
  • Working pressure: 3 ~ 7 bar
  • Body Material: ASTM A53 Pipe

Rim Seal Foam Pourer

Rim Seal Foam Pourer is designed to discharge fully aspirated foam directly to the annular seal area of the open top floating roof storage tanks for fire or vapor suppression. Fully aspirated foam provides the most effective performance.
Foam pourer design provides protection from the wind, allowing the aspirated foam to gently discharge onto the protected area of the floating roof tank.

  • Application: Foam Solution, 1%, 3%, 6%
  • Expansion Ratio: 6:1 15:1 at 5 bar (depending on Foam Type)
  • Working pressure: 3 ~ 8 bar
