Can You Blow Into The Bag Please, Sir?

Stephen Benton from Cool Concerns reviews the CoilPod, a solution for cleaning condensing coils on refrigeration units. 
How many times have you been enjoying that secret refrigeration engineer’s pleasure, blasting debris from a blocked condenser, only to turn and see your customer’s face dropping as you cover his emporium of fine food with Sh1T?

So, with perfect planning and all that, we introduce the CoilPod – coil dust containment bag, truly a bag for life, your own life as a cleaver-yielding butcher chases you out of his shop less than happy!
As with all good ideas they are simple; the Coil Pod is what it is, a big bag with a drawstring and a port to put a vacuum cleaner nozzle through and another smaller one to put your nitrogen or compressed air gun through.

With your bag neatly over the condenser coil and fan plenum and your vacuum cleaner running you can begin the dusty exercise looking with safety through the Coil Pod’s clear plastic front whilst vacuuming the airborne dust and debris as you go!

​We tested it in our workshops on one of our C&G 2079-11 assessment rigs using a full mug of debris from our vacuum cleaner placed inside the Coil Pod.

​We blasted down into the mug with nitrogen and found the bag contained 99% of the debris with a small amount inevitably escaping downwards onto the condensing unit base; however this simply dropped onto the base and was vacuumed up later. The air space in our workshop remained completely uncontaminated.
The bag is a very simple concept and it is worth noting that a clean condenser will significantly improve energy efficiency; for every 1 degree C reduction in condensing temperature there is approximately a 2% to 4% drop in energy consumption.

It also follows that the system will run for less time and while it is running at a reduced condensing pressure there is less likelihood of leakage and the compressor is running at less onerous conditions. 
 
​"We hear a great deal about carbon footprints and energy efficiency but often the most simple maintenance routines have the greatest impact!"
 
​On a recent site visit we measured a remote condenser’s operating conditions before and after cleaning and observed a 5 degrees C drop in the condensing temperature after simply brushing the debris from the surface of the coil.
