ARCHITECT EMBRACES THE HEALTH BENEFITS OF TITON’S NO2 FILTERS

Two Titon HRV10 Q Plus units with Trimbox NO2 Filters® have been installed as part of unique self-build project in East Dulwich, London.

 When architect Jake Edgley began building his own six-bedroom house, he included a mechanical ventilation with heat recovery (MVHR) system as part of the design, alongside other ‘green’, environmentally-friendly measures, including non-toxic paint and flooring.

The 400m2 house was constructed in two halves, each built around a tree, with one MVHR system covering each half of the property. As Jake designs and specifies homes as part of his job, he often experiments with different products on his own property. Having included Titon’s ventilation systems on a number of projects during the last ten years, he was already fully aware of the company’s product offering.

Commenting on the decision to have nitrogen dioxide filters added, Jake said: “We noticed if a neighbour lit a bonfire or a barbecue, the smell would still enter the house. Fortunately, I had seen the Trimbox NO2 Filter® on the Titon website, so I made enquiries into the possibility of adding one to the ventilation system.” 

The bedroom area had the Trimbox NO2 Filter® added first, and the Edgley family were so impressed with the results, a second unit was installed to the other half of the house six months later.

Jake explained: “The Trimbox filters work amazingly well, they have completely eradicated any smells coming in from outside. In fact, if we smell smoke outside, we just close all the doors and windows, and there is no trace of any odour indoors. The MVHR unit is already a good dust filter and this is improved by the Trimbox, and we’ve also noticed the Trimbox acts as an excellent attenuator to any noise from the MVHR unit. Then there’s the added benefit of knowing the units are filtering out any pollutants so, despite being located about 60 metres from a road, the air inside the house remains clean and healthy.”

Jake now certainly practices what he preaches, as his positive first-hand experience has led him to include the Trimbox NO2 Filter® as part of every new build domestic ventilation system specified by his company, Edgley Design.

“The Trimbox is a great product, particularly in London areas,” he concluded. “Given the rise of environmental toxicity over recent years, we always encourage domestic clients to put MVHR systems into new build homes. Including the Trimbox as part of the system should make perfect sense to homeowners, especially given its capacity to remove diesel particulates and filter toxins from indoor air.”

Titon developed the Trimbox NO2 Filter® to complement its extensive range of HRV Q Plus Eco MVHR units and combat the high levels of nitrogen dioxide found in exhaust gases from diesel engines. The filter incorporates balanced flow technology to provide class leading absorption of NO2 and is available in two duty sizes (depending on the duty required). The product is effective in reducing NO2 to an acceptable mean annual concentration level of 40µQ /m3, while vastly improving indoor air quality (IAQ). Independent tests have demonstrated the Trimbox to absorb 98% of NO2, not only in normal, continuous ventilation mode but also at ‘boost’ or higher ventilation rates.*

Domus Ventilation MVHR wall units now with Bluebrain control

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.

Polypipe Ventilation’s HRX-aQ MVHR system announced as a finalist in H&V News Awards

Polypipe Ventilation is pleased to announce its Silavent HRX-aQ Mechanical Ventilation with Heat Recovery (MVHR) appliance has made it as a finalist in the prestigious H&V News Awards, in the Domestic Ventilation Product of the Year category.

The H&V News Awards, now in their 23rd year, are an annual celebration of excellence, forward thinking and the highest achievements across the building services industry. The awards cover the entire HVAC and building services supply chain. This year’s awards saw a high number of quality entries submitted, so making it onto the shortlist is a major achievement for all concerned.

Polypipe Ventilation believes its Silavent HRX-aQ MVHR appliance cut through the competition because of its ability to intelligently manage air conditions, for maximum homeowner comfort.

Properties come in different design styles, fabrics, locations and orientations, all of which have an impact on their thermal behaviour. Furthermore, occupants’ comfort levels can vary significantly. The HRX-aQ has been designed by Polypipe Ventilation to take these factors into account, matching ventilation rates to the internal environment and occupants’ requirements for maximum comfort, whilst also being the quietest and most compact (from 199mm in depth) Silavent MVHR unit available.

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.

Unlike conventional humidity sensors, the HRX-aQ enables occupants to have direct control over managing the humidity levels in their home to suit personal comfort levels. By accurately measuring air humidity, the HRX-aQ’s extract speed automatically changes from background to boost as the level of humidity increases, thereby providing optimal ventilation performance.

Similarly, the HRX-aQ features advanced bypass control, programmable by occupants based on time or temperature. In standard mode the MVHR units work by warming fresh air drawn into the building using the heat from waste stale air extracted from the kitchen and wet rooms. In conjunction with multiple time controlled bypass options (night time free cooling), the Silavent HRX-aQ also detects when air temperature reaches a pre-set level and intelligently activates the bypass mechanism allowing in cooler, fresh and filtered air.

Control of these features is achieved via a 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 Polypipe Ventilation’s previous Silavent MVHR ranges, the new HRX-aQ remains extremely efficient. When used with a kitchen and one wet room, at typical installation, the HRX-aQ provides an 88% heat exchange performance and boasts a very low Specific Fan Power down to 0.66W/(l/s) – providing the property with a lower Dwelling Emission Rate and additional project SAP points.

There are eight HRX-aQ models available to suit a wide range of residential properties, including units with a specialist heat exchanger technology to further improve air quality and provide comfortable humidity levels.

Titon adds semi flexible sound attenuators to its MVHR portfolio

Titon has introduced Semi Flexible Sound Attenuators for use with its HRV Q Plus range of MVHR systems. The new products consist of a strong, multi-layered, corrugated and perforated aluminium inner duct, which is surrounded by an aluminium/polyester laminated outer jacket. The space between the inner and outer duct is filled with 25mm sound absorbing material.

Quick and simple to install, the Semi Flexible Sound Attenuators minimise air flow resistance, providing acoustic and thermal insulation, while fulfilling BS EN 13180: Ventilation for Buildings – Ductwork. The new attenuators can be installed directly onto the outlet of the MVHR unit, reducing both the duct and breakout noise levels. They also help prevent noise transmission through vibrations by isolating the MVHR unit to the ducting. The products are available in standard lengths of 0.5m and 1m, plus their flexibility in shape and length makes them ideal for connecting misaligned ducts.

Commenting on the latest addition to the MVHR range, Paul Cowell, Senior Technical Manager at Titon, said “As opposed to rigid alternatives, which require a high level of accuracy during installation, the Semi Flexible Sound Attenuators enable a useful degree of flexibility (and length) to simplify the fitting process. The aluminium inner duct maintains a smooth path for the airflow, minimising resistance while enabling the ductwork to be routed for a neat installation. They isolate the ductwork from the unit, in turn minimising possible noise transmission through vibration.

“They are also suitable for in-line duct applications, due to a low profile which can offer an advantage over rigid silencer solutions in ceiling voids with limited space.”

Titon’s Semi Flexible Sound Attenuators can operate at a pressure up to +2,000 Pa, at a maximum operating air velocity of 10 m/s. The temperature ranges are -30°C to 250°C for the inner duct and -30°C to 140°C for the outer jacket. The products can be installed directly onto the outlet of the MVHR unit, reducing both the duct and breakout noise levels.
