How do you fit a RABScreen™?

How do you fit a RABScreen™ the industry standard air intake screen? 

You could use the standard drop tab or twist lock fitting. This involves drilling two pilot holes per tab and can be risky when installing around chiller coils. You need to use a good fridge engineer to make it safe. We always do.

Alternatively, you could use a smaller grommet and self-drilling stitching screws. Again you need to be careful as it is too easy for inexperienced fabricators to puncture a coil.

You might want to try the aluminium profile T Track option but that is outdated and time consuming.

We have magnetic metallic frames, Velcro vinyl border frames, 9.5mm and 6.5mm stainless steel grommets in a stitched vinyl border, Kanya aluminium rigid profile frames and now the MagnaMount™.

The MagnaMount™ is a real advance for everyone. No more specialised labour, no drilling or screwing just measure the opening and fit your RABScreen™. And with the MagnaMount™  Mount Plate it can be used on non-magnetic surfaces as well.

This makes large or small intakes perfect for protection by a quality electrostatic product with an ROI of less than 6 months.

Why consider a single fixing option when we can design, manufacture and supply a filter exactly how you need it. The unit below had extended pipework which would have been easily damaged by a screw or drill. The supporting uprights are in the way and so we designed a perfect solution for this large paper mill.



  • Vinyl border at the top with stitched in magnetic strip.
  • Plain vinyl border at the bottom.
  • Cut outs to avoid the uprights.
  • MagnaMount™ fittings on 9.5mm grommets to both sides.

Cooling tower protection


The above picture shows a cooling tower installation. 

It is a Carter Environmental Sandringham unit with a 48 inch Flakt Woods air intake fan.

This factory produces paper products which are trimmmed and the waste is sent to a nearby compactor. Unfortunately some of the fines end up on the floor and the grass verge is very close to the inlet.

Problem? 

Grass pollen, insects, grass seed, grass clippings, road dust and paper fines all being sucked into the sump by the 48 inch (approximately 1219mm) diameter fan.

Consequence?

More sludge, more disinfectant, more cleaning.

Solution?

The installation of a 3-D circular RABScreen to the fan guard and protect the intake from the debris.


The RABScreen needs cleaning every two weeks. The debris is highly visible and was originally turning into a nutrient source for bacteria. Now it is simply brushed  off.

Keith the Maintenance Engineer for Cotek Papers said "this is the best thing I have ever bought and it is so easy to clean".

Datacentre efficiency

Data centres are responsible for well over 2% of the total electricity consumption worldwide and it makes you ask why they are not investing in air intake protection. 

Roel Castelein, marketing chair of the Green Grid, stated in a recent news article:

“Only 29% of data centres appear to have any semblance of a reliable system by which management can measure the relative energy performance”.

Castelein also states that all (data centres)

“are concerned about the bottom line”

and points out that

“data centre operators can incorporate measures to increase energy efficiency, reduce their carbon footprint and improve sustainability”.

We have visited a many datacentre sites with a view to protecting their cooling plant from airborne debris. 

Depending upon the load and N+ specification, a datacentre will have many identical units all requiring regular maintenance to proof the site against unforeseen failure. 




When looking at capital investment on critical plant the major driver must always be energy saving. This can be achieved by using high efficiency motors with infinite control as well as micro fin coils which create a larger surface area for heat dissipation.

Unfortunately, in too many cases the cooling plant is then exposed to the debris of the local environment. Coil clogging is a major consequence and routine cleaning and maintenance can easily damage the fins, reducing surface area and increasing energy demand. 




A RABScreen can be used to prevent this contamination by placing an electrostatic layer between the incoming air and the coil fins. High efficiency particle capture allied with low resistance makes the RABScreen a prefect choice for any Datacentre Manager. 






Until now it has been relatively easy to fit a protective screen onto a coil face. You just need to take a little care and preferably employ a specialist refrigeration engineer to clean and fit. 




The introduction of the new MagnaMount™ has made installation very simple and so there has never been a better time to talk to us about your cooling plant.

Generator sets in dusty climes

Generator sets in dusty climes


Engine covered in dust on a generator
generator filter dustOne of our clients recently purchased four second hand generators from an airport. Although an important part of the emergency systems they had only completed a short service life of less than 90 hours.

Now they were in a quarry with no other form of electrical power supply. Their new duty required them to work for 10 hours per day, 5 days per week in order to power the crushers, conveyor belts, screens and other miscellaneous equipment associated with mining and processing stone.
Now they were located in the middle of all this activity which created a lot of dust from the blasting, crushing and screening processes.

These pictures were taken after only four weeks service. The engine air filters only lasted 3 weeks before they needed changing and the client thought that there was nothing he could do about it. Luckily he found RAB Specialist Engineers Limited and the unique RABScreen external air intake filter screen. It can be easily mounted over the air intake louvre and will prevent the dust from getting into the container.
But what about airflow? With only 22 pascals resistance at 3.05m/s this is not affected. And all for the cost of a couple of engine air filters.

A great solution using a great product in a new environment for RABScreen external generator intake filter screens.

And now available with the brand new MagnaMount™ magnetic fixing as an alternative to drilling. 

Simple solutions by RABScreen. The industry standard air intake protection.

An interesting article which shows that buildings, even old buildings, can benefit from new technology and a large amount of TLC. And RABScreen can help with that efficiency drive especially on a vegetated roof!

A no fix fixing from RABScreen



for a no fix fixing to protect your equipment

rabscreen air intake magna mount


After considerable research and testing, Permatron in Chicago have developed the unique MagnaMount™ drop tab fitting. This now eliminates the risk of damage to cooling coils or other equipment from drills or screws. 

Anyone can fit a RABScreen air protection screen without the need for tools. 

Eliminating the need to drill into equipment, MagnaMount™ mount clips contain a powerfully strong neodymium “earth” magnet that sticks to metal surfaces, allowing them to be repositioned as needed. Non-metallic surface installations are also easy with the addition of the press on steel plate adapter containing high bond, high tensile strength tape adhesive permanently affixed to surface. (Model #MountPlate)

Independently tested for use in outside environment - passed 120 hours (60 months/5 years) NSS Testing – ASTM B117 (Outside environment definitions: Temperature -25 to 55 C, RH 40%-90% No salt water/corrosive)

In any application (metallic or non-metallic) you can now reduce fitting time to a  minimum, remove the potential for  damage by unskilled labour and protect all of your air intakes simply and effectively. 

All we need are the fixing points centre to centre and your RABScreen with MagnaMount™ no fix fixings will be supplied.
