Following the launch of its ceiling/void mounted HRX-aQ Mechanical Ventilation with Heat Recovery (MVHR) appliances with intelligent air management, Domus Ventilation, part of Polypipe, has introduced this same advanced ‘Bluebrain’ control to its wall mounted MVHR units.
The new Domus HRX-D and HRX-2D wall mounted MVHR units intelligently match ventilation rates to the internal environment and occupants’ requirements, for maximum homeowner comfort. This is achieved through advanced AMIE (Air Management for Indoor Environments) technology including features such as digital humidity control, automated summer bypass and accurate system balancing.
By accurately measuring air humidity, the HRX-D’s extract speed automatically changes from background to boost as the level of humidity increases, thereby providing optimal ventilation performance. The thermal (summer) bypass feature operates in a similar manor, automatically activating when the air temperature reaches a pre-set level, allowing in cooler, fresh, filtered air, instead of distributing air which has been warmed from the waste energy extracted from the kitchen and wet rooms.
For the homeowner, a key benefit is that these features can be easily programmed by them based on time and temperature. This flexibility enables all comfort levels to be catered for, regardless of the type of property and its construction.
At the heart of this intelligent air management is Domus Ventilation’s compact Bluebrain control, which also provides homeowners with helpful maintenance reminders for cleaning and replacing filters to ensure performance of the unit is maximised and air quality maintained.
As with Domus Ventilation’s previous MVHR ranges, the new HRX-D remains extremely efficient. When used with a kitchen and one wet room, at typical installation, the HRX-D provides an 88% heat exchange performance and boasts a very low Specific Fan Power down to 0.66W/(l/s). It is also exceptionally quiet, with background (normal) ventilation at 24dB(A) (typically whisper quiet).
The HRX-D has been designed to work most efficiently when used with Domus duct systems, including its new Flow Control Plenum and High Efficiency Green Line Bends, which reduce duct bend resistance by up to 60%. Domus duct systems offer improved system performance through the exacting tolerances and engineered fit of the system, whereby pressure drops are minimised and air leakage virtually eliminated.
Sitting alongside the ceiling/void mounted HRX-aQ unit, the HRX-D has been designed for installation smaller properties, whilst the HRX-2D for larger houses. They are suitable for installation in a cupboard, utility room or loft.
Domus Ventilation has a well deserved reputation for quality, supported by excellent technical support, from a market leading manufacturer and designer. It is well placed to offer immediate, practical solutions to Building Regulations Parts F & L. The company continues to provide differentiated solutions in the private and social housing sectors, transforming the way developers, specifiers, installers, home owners and distributors meet emerging environmental standards.
