The patent-pending ECD economy line of diffusers from SSI Aeration, Inc. provides an affordable price point for cost-conscious customers. SSI use a single-mold technique with EPDM membranes to create the ECD series. As a result, clients receive a cost-effective product suitable for a variety of applications. When a project lead needs to factor capital cost into their system design, the ECD series can meet many project requirements.
SSI offers ECD diffusers for sale in 7-inch, 9-inch, 12-inch, and 20-inch diameters that feature a 3/4 MNPT connection and compatibility with SSI’s PVC grommet.
The SSI facility uses a single mold during production to save costs for customers. Each ECD unit has an integrated membrane created with SSI’s standard EPDM membrane. By creating the ECD series with a single mold, SSI can save costs during production and pass those savings to the client. To provide the reliable performance associated with SSI products, ECD diffusers include an EPDM membrane.
After producing the single-mold body, manufacturers inject an EPDM membrane with similar qualities to the membranes on other standard SSI products. The membranes on ECD series products have compression molding with individual thermocouples in each cavity. This process allows the manufacturer to have full control over each diffuser membrane’s quality. SSI also ensures that each membrane’s perforations have even depth for uniform air release. An ECD diffuser membrane has low plasticizer content to reduce hardening and shrinkage while avoiding creep.
