Heat exchanger filters for a clean machine

Within the processing industries, a problem that many companies face is the cooling water fouling of heat exchangers: solve this with the Ronningen Petter backwashing/tubular filter systems

Within the processing industries, a problem that many companies face is that of cooling water fouling-up heat exchangers.

One way of minimising this problem is to use Ronningen Petter backwashing/tubular filter systems.

These systems consist of a series of filter tubes mounted on a common inlet, outlet and drain headers.

The headers have 'pulled' openings so there aren't any areas for contaminants to settle.

Process liquid flows into the inlet header and is evenly distributed into each of the filter tubes.

The liquid flows from the outside to the inside of each filter screen, depositing contaminants on the outside.

The clean liquid then exits via the outlet header, continuing downstream to the process plant.

Because every process is unique, RPA offers several systems in differing configurations providing solids removal from 1-1700microns.

However, Mike Buhagiar advises that there is growing demand for the F and AFR Series.

"For liquid filtering applications that require unattended operation, maximum uptime and solids removal, the F-Series offers users high levels of versatility due to its modular design," reports Mike Buhagiar: "Providing both internal and external backwashing capabilities, F-Series systems can include 2 to 20 body tubes on a single framed skid and can be ordered with blank stations to allow low-cost expansion.

Where space is at a premium, the AFR Series can replace an 8 station multiplex tubular system in a one square metre footprint area.

It is ideal for high volume, low viscosity applications handling flow rates of up to 454m/h".
