Dunham-Bush masterclass in education ventilation
Dunham-Bush has signed an exclusive agreement with Eco-Airvent to manufacture and distribute their energy efficient Classmaster heat recovery ventilation units.
Classmaster has been developed specifically for classrooms and fully complies with the very latest BB101: Ventilation, thermal comfort and indoor air quality 201’ and BB93: Acoustic designs for schools, performance standards (2015) guidelines. With nine chassis sizes and airflows ranging from 50 to 600 l/s, Classmaster delivers high standards of air quality to meet every classroom requirement.
Key features include a patented variable air mass flow heat exchanger, which maintains thermal efficiency at both 100% and 50% airflow levels by cleverly keeping turbulent velocity airflow across the heat exchanger. This is not possible with conventional heat exchangers as airflow goes into a laminar flow with no exchange of thermal energy.
In line with the latest BB101 guidance bulletin, Classmaster units have the option of ePM2.5 (F7) filters for inner city installations.
With a low profile height of only 300mm, the product can be installed within a ceiling void or surface mounted. A space heating option is available with frost protection and a comprehensive range of heating coils pre-installed in insulated casings and matched flanges to fit directly onto the heat recovery units.
Full integration with BACnet or Trend systems for energy management and monitoring is available with filter monitoring via built in PDF switches. Additional ultra-low energy summer trickle mode and a full space heating facility using a re-circulation damper and LPHW coil are included in the programming. Optional colour touch screen user fan controllers with built-in temperature and humidity sensors are also available.
