I’ve got a big one, can you help?

Galebreaker Rolling filters can go up to 60 meters long, so we can handle it!

Cooling systems come in all shapes and sizes, ranging from very small light industrial coolers around the size of a domestic fridge up to cooling systems that are larger than football pitches.

Inlet filtration is designed to trap some of the airborne contamination before it enters your cooling system in an easy to clean location, rather than lodged within the systems themselves, where it is often very difficult to remove debris.

For dry cooling systems the airborne contamination builds up between the fins restricting airflow, but also reducing the effective cooling surface, which leads to lower performance. The delicate nature of the fins generally means that cleaning must be done carefully to ensure that damage does not occur, but it also tends to mean that gentle cleaning of the fins is not always effective, so being able to collect this debris in an easily accessible location means cleaning is easier and more effective, even if it is required a little more frequently.

In the case of evaporative cooling reducing the amount of nutrients that are drawn into the circulating water can help to reduce fouling in the fill pack, or a build-up of contamination in the water system. Less nutrients means less bugs which in turn reduces the chemical demand associated with killing bugs, and less chemicals can prolong the life of the materials of the cooling system.

The Solution

A facility in Europe installed some large cooling towers that required filtration on air inlets measuring around 30m long x 3m tall. This was achieved by using a single rolling system across the complete 30m long air inlet face that can be simply manually rolled away for access by a single operative.

The system is attached to the cooling tower structure along the length of the inlet, with the total weight of the equipment being that of the fabric and the rolling bar. Retaining bars are installed at intervals along the length of the screen to contain the screens.

The rolling bar is manually driven using a small hand driven gearbox to allow an operator to roll the entire screen away for access into the cooling system, this arrangement allows costs to be kept to a minimum with a single drive unit being able to serve more than one cell.

This system can very easily be motor driven and even automatically deployed based on a signal, depending on the desired function.

It is possible to deploy this screen during operation, which is a big problem with loose screen options, and changeover of the screens for any reason requires the minimum of time as the screens can simply be slipped out of the retainers and replaced, which is a 20 minute operation.

Key Points

  • Cost effective, bespoke inlet filtration system.
  • Easy and fast installation, onto almost any plant or equipment.
  • Minimal additional steelwork required.
  • Longer Screens Available up to 60m.
  • ROI Will be realised in reduced cleaning intervals and lower chemical demand.
