2 Discover Radial MVHR Systems
Old-fashioned MVHR systems typically use a 'trunk and branch' Air Distribution System. However, recent advances in ventilation technology ensure that today, more and more ventilation professionals are now choosing a 'radial' system instead. But what is an air distribution system? What is a radial system? What are the benefits? And how do radial systems differ from trunk and branch systems?
What is an Air Distribution System?
An air distribution system is simply the pipework or ductwork that forms part of an MVHR installation. The pipework connects the MVHR machine to individual rooms, collecting and distributing air within the home.
What is a Trunk and Branch System?
Old-fashioned trunk and branch systems begin with a single section of large diameter (typically up to 200mm) pipe, which connects to smaller diameter (typically 100mm - 125mm) 'branches', supplying to and extracting air from each room in the home. Usually, the duct is manufactured from steel, or a similarly rigid material. Because each branch originates from a single duct, sound attenuators must be fitted to minimise noise and sound transfer between rooms. Failure to fit an attenuator can prove at best a nuisance, and at worst, positively embarrassing.
What is a Radial System?
A radial system uses a series of manifolds to connect pipes to / from individual rooms and the MVHR unit. The pipe used is typically no greater than 75mm diameter and is often manufactured from a semi-rigid polymer. Because there is no direct link between any 2 rooms within the home, the risk of noise transfer and cross-talk is all but eliminated.
What are the benefits of choosing a Radial System?
Ventilation professionals across Ireland have been quick to seize upon the benefits that radial systems provide. These include:
- Reduced pipe diameter makes for a more space-efficient layout, with less height required for ceiling voids;
- Semi-rigid, plastic duct, eliminates the requirement for hot works and specialist trades on site;
- Simpler system design with consistent pipe diameters throughout the home;
- Reduced requirement for heavy lifting on-site;
- The risk of noise transfer and cross-talk between rooms is all but eliminated;
- Fewer joints, with reduced risk of air leakage and resulting pressure loss.
Frequently, radial systems can also be installed more quickly and at a lower cost than old-fashioned trunk and branch systems. So it certainly makes sense to consider radial for your next project or build.
Do all systems today feature a Radial design?
No, surprising as it may seem, some manufacturers still persist with a 'trunk and branch' approach. However, as a leading supplier of MVHR technology to Irish ventilation professionals, we only
specify, distribute and supply radial MVHR systems.
