DUNHAM-BUSH PROVIDES A MASTER CLASS IN LOW ENERGY VENTILATION FOR CLASSROOMS All ventilation systems must have the capability to operate in typical UK weather conditions, including high winds and rain. Final ventilation designs will depend on the following key factors: • Building location • Type of construction •Site ambient noise levels • Local air quality / levels of pollution •Amount of glazing / solar gain •Patterns / type of use Dunham-Bush has signed an exclusive agreement with Eco-Airvent to manufacture and distribute their range of innovative, energy efficient ventilation products, including the patented Classmaster® and VHR heat recovery units. Air quality in classrooms has a major bearing on the academic performance and productivity of occupants and with air pollution levels continuing to rise in the UK, especially in cities, it has become increasingly important that these issues are addressed. Released by the government last year, BB101: ‘Ventilation, thermal comfort and indoor air quality 2018’ has been instrumental in the most significant changes in ventilation design, regulation and guidance in schools since 2006. Working in parallel with BB93: ‘Acoustic designs for schools, performance standards (2015)’, it gives a detailed holistic approach to the internal environment in schools with the emphasis very much on energy efficiency. BB101 guidelines on ventilation, include standards for all spaces within a school or college and new guidance for science labs and other practical areas. VERSATILE CONTROL OPTIONS The factory fitted Eco-Pro 3 controller offers a plug and play capability and is ideal where stand-alone control is required. Units can be activated either via volt free contact (VFC) from a time switch or BMS (enable / disable signal). The controller can give fault outputs either to the Eco-Fault panel or BMS panel. Individually adjustable fan speeds on trickle and boost settings with frost protection, automatic summer by-pass and night time cooling options are included as standard. Fans switch automatically to boost speed when CO2 is detected. www.dunham-bush.co.uk Classmaster NEW FROM DUNHAM-BUSH ® ULTRA LOW ENERGY HEAT RECOVERY VENTILATION FOR CLASSROOMS ✔ Patented variable mass heat exchanger ✔ Maintains thermal efficiency at 100% and 50% airflow ✔ Fully compliant with BB101 2018 ✔ Up to 82% efficient energy reclaim ✔ 100,000 hour long life, low energy EC fans ✔ Low profile, only 300mm in height ✔ Low sound levels ✔ Inner city filter ePM 2.5 (F7) ✔ Trend Bacnet control ✔ Space heating option A master class in low energy ventilation for classrooms E-mail: [email protected] www.dunham-bush.co.uk WELCOME TO THE COMFORT ZONE V E N T I L A T I O N
