PRODUCT REVIEW
“Modern heating systems regardless of size are becoming more and more dependent upon clean, suitable water quality.”
designed for continuous venting of air, down to the level of micro- bubbles (gradual and continuous degassing) and may be installed on either a vertical or horizontal pipe. For debris removal older systems may well have filters or strainers fitted, which will remove larger particles. There are two issues with this. The first is that smaller particles will not get trapped such as fine sand, rust and magnetite. Second, the strainer will cause a loss in water pressure in the system, which is only made worse as it gets clogged up. Whilst strainers need to be regularly removed and cleaned if they are not going to affect the efficiency of the heating system, modern dirt separators exploit gravity to remove even very small particles down to 5µm by reducing the speed of the water passing through it, which also means that it minimises any loss in operating pressure. Some, such as Altecnic’s Dirtmag
Mini, have triple dirt and air separation features. This includes an air vent for air separation, an internal polymer element for particle separation and hydraulic performances and also features a power magnetic dirt separator. Ferromagnetic particles are retained in the collection chamber and prevented from returning to circulation. A drain cock with a hose connection allows for the simple removal of impurities. Full bore isolation valves also allow for ease on servicing while the filter is in-situ. They are also available as part of compliance packs which include aerosol cleaner and inhibitor chemicals. There are many older commercial heating systems out there where air and dirt build up is an on-going problem and worse still, they don’t have the latest technology to manage it. The Altecnic DISCALDIRT 546 Series deaerator-dirt separator, available in sizes DN50 – DN 150, uses
the combined action of several physics principles to solve this problem. The active part consists of a set of concentric metal mesh surfaces. These elements create the swirling motion needed to help release micro-bubbles and their adhesion to the surfaces. The bubbles, fusing with each other, increase in volume until the hydrostatic thrust is sufficient to overcome the force of adhesion to the structure. They then rise towards the top of the device and are expelled through a float-operated automatic air vent valve. The impurities in the water, colliding with the metal surfaces of which the internal element is composed, are separated out and fall to the bottom of the valve body. Preventative heating system maintenance helps keep them efficient so it is worth explaining to your customers how they may benefit from modern air and dirt removal systems.
