Primary concern with any under-floor thermal radiation system is the clogging of manifolds and pipelines by the debris from old radiators as well as suspended particulate matter in the water or the circulating fluid. However, a simple sieve filtration system for the elimination of this matter is not sufficient because of the difficulty in repeated removal of filter medium for cleaning. A possible solution for the clarification of circulating fluid is a Spirotrap dirt separator. It works on the principle of separation of matter using centrifugal force and turbulence. A stream of water contaminated with particulate matter enters a vessel with a patented spirotube in it under a certain pressure and a sudden velocity drop is experienced. The dirt particles of all sizes drop down to the bottom of the vessel and get collected into the dirt collection chamber which is outside the main flow area.
Particulate matter falls to the base of the vessel from where it can be collected and removed through a normal open-close valve. The Spirotrap dirt separator has the benefit that it is easy to install and service, which is vital because of the location of the under-floor arrangement. The Spirotrap dirt separator can be adjusted for any house’s heating needs and flow rates. It is very conveniently placed so that the dirt collected while circulating in the radiator can be removed from the system before it enters the boiler.
The Spirotrap dirt separator also has the advantage of not having any special moving parts, thereby helping to save wear and tear of the component, which can in turn bring down the running and maintenance of the whole under-floor heating and radiating system.
In addition, the Spirotherm dirt separator does not have any special collector bags which hinder the actual cleaning efficiency of the entire system and the flushing of the dirt can be done while the whole system is operational.
