Cooling Plant Air Intake Protection

All cooling coils will get dirty with coil dust and this will reduce the overall performance of the equipment. To see an example click this link.

“When the coil becomes fouled with dirt and grime, it cannot provide complete or adequate heat transfer, a process that was predicated on a clean coil. The equipment’s compressor senses this and tries to overcome it by going to a higher system pressure. This consumes greater levels of electricity” Professor John Tomczyk

A 1mm layer of chiller coil dust or dirt insulating the coil fin can reduce efficiency by 21% and increase energy use by as much as 30%. It has the same effect on large or small condensers.

The RABScreen chiller air intake screen will filter the air before it hits coil fins and helps to stop coil clogging which maintains the cooling surface area and ensures that your equipment runs effectively without head pressure build up. ROI is usually less than six months and for smaller units, we have the unique Permatron Wrap Around from only £40.00.

When it gets dirty, clean it and leave it protecting your cooling systems for at least 10 years.

Mounting Options

RABScreen filters can be used wherever you have air movement and, because they are weather resistant, are suitable for both internal and external applications.
