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.”
He added:
“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.
