SSI PTFE coated EPDM membranes continue to outperform competitors' products in side by side tests, and in hundreds of reference plants around the world.
SSI PTFE discs were selected by Saudi Arabia for more than Makkah and Jeddah WWTP's. The combined orders are for more than 200,000 diffusers.

SSI PTFE tubes were selected by CJ Co. of Korea for all of its food plants worldwide including Korea, China, Indonesia, and Brazil.
SSI PTFE discs were selected by Yorkshire Water of the UK for its framework contract to serve as the primary diffuser supplier for the next 5 years.

In September, we tested our 3rd generation of disc diffusers (both EPDM and PTFE, both 270mm diameter and 350mm diameter) at ATC, SA in Barcelona, Spain. This is same well regarded testing firm that performed similar tests in 2003 & 2004 on previous generations of our disc diffusers.

This year we achieved the highest oxygen transfer results ever. You can be confident that systems installed with SSI 3rd generation disc membranes are performing at the peak efficiencies available in our industry from any manufacturer.

K-series axial fans are designed for application in factory assembled cooling towers and air-cooled heat exchangers. This is a pure Howden quality product, with superior performance at lowest power consumption and with timesaving features.

K-series fan blades, with the innovative "Aerotip" (patented) and the radius-cut inboard edge, have been designed for a high power recovery providing excellent aerodynamic performance. The resilient and damped connection of the fan blades to the hub guarantees the fan will operate smoothly and silently without vibration problems.

Howden Z-series axial cooling fans are the latest in axial fan development. They are specifically designed to operate at peak efficiency at the most common duty points in field erected cooling towers and air-cooled steam condensers.

Z-series cooling fan blades have the innovative and patented "Aerotip" blades developed by Howden. See Aerotip paper as presented at CTI meeting (PDF) at www.howdencoolingfans.com/files/upload/Paper_TP03-05.pdf

Z-series cooling fans have a blade construction with an integral shaft and are positioned on the fan hub-plate through aluminium blade supports using U-bolts for simple assembly and field adjustment.
