What Makes the SSI ECT 70 Tube Diffusersa world wide choice ?SSI’s ECT70 tube diffusers are designed to offer high oxygen transfer efficiency, low pressure loss, and a simple installation. Our new ECD70 diffusers are available with a variety of membrane materials including our patented PTFE membranes, designed to use less energy and require minimal maintenance. Strong Polypropelyene body makes handling during installation easy, provides temperature resistance up to 1900 F (900 C), and is environmentally friendly. ECT diffusers feature a channel style support body which extends membrane life in on/off applications.

Unique System StrengthsComplete product line – creating the system that �ts your needs
, tube di�user ,products on a wide range of piping materials including PVC, CPVC, PP and Stainless steel. We have
provide retrievable systems or �xed grids, and systems in kit form or mostly factory assembled. We try to understand and anticipate your needs, and �t our recommendations to your situation.
Piping system integrity – thicker wall pipe and double anchors for fewer breakages Our piping is 38% thicker and has double rod support stands as standard – two anchors for each support
temperature and water velocity. SSI locates two anchors where support is needed most, helping to increase product longevity.
SSI provides full design services, including biological and mixing calculations, process simulations and
assist with speci�cations and CAD drawings. Our service and installation crew can hold your hand during
satisfaction.

Why choose the SSI ECT Di�user?SSI developed the ECT tube di�user to bring a quality tube di�user at an a�ordable price to the wastewater market. In low air�ow rates the bottom part of a conventional 360 di�user is inactive. The ECT di�user functions similar to a panel di�user resulting in a higher SOTE rate.
Intelligent Upgrade OptionsP SSI’s patented PTFE membrane barrier properties not only reduce plasticizer extraction, shriking, and membrane hardening but also limit dynamic changes that can result from swell, such as creep. Compared with uncoated products that are more susceptible to increases in DWP due tomore aggressive fouling and changes in physical properties and weight, the PTFE coated membrane improves consistency of DWP (Headloss) values over the product life. This directly impactslong-term power costs and the ability of the system to distribute air uniformly across the tank �oor.

* All di�users can operate at low �ow rates close to zero in such conditions air distribution may not be uniform at higher rates fouling are possible so routine bumping / �exing may be appropriate.

Conventional Tube vs ECT Tube Di�usersSSI’s ECT di�user is capable of producing a higher SOTE compared to conventional tube di�users. ECT di�users are more e�ective at lower air�ow rates when conventional tubes would only be partially activated.
