AIR2AIR HEAT RECOVERY HEATING & VENTILATION
In hotels, high occupancy levels generate significant heat and moisture, while modern airtight construction can trap stale air and CO₂. Biddle's Air2Air Heat Recovery System tackles both challenges at once — continuously delivering fresh, filtered air while recovering up to 80% of the heat from outgoing stale air, dramatically reducing the energy cost of ventilation across the property. INTELLIGENT VENTILATION CO₂ demand-controlled ventilation adjusts performance based on actual occupancy, ramping up during busy periods such as breakfast service, wedding receptions and conference events, then easing back when spaces are quieter. The result is consistently fresh air where guests need it, without the energy waste of running ventilation at full capacity around the clock.
HEATING & VENTILATION SOLUTIONS
Biddle's heating and ventilation solutions maintain a consistent, comfortable temperature throughout public buildings and office environments. Compatible with modern low-temperature systems including heat pumps, they deliver efficient, quiet performance across spaces of every size and configuration.
FREE COOLING IN SUMMER
A built-in summer bypass mode brings cooler outside air directly into the building during warmer periods, bypassing the heat exchanger – providing free cooling and helping to manage humidity in lobbies, restaurants and event spaces during peak trading. This protects both guest comfort and operating margins through the warmer months.
BENEFITS
VARIANTS
Precise zoned temperature control across diverse space types High-efficiency EC motors minimise energy consumption Full BMS integration for centralised energy monitoring and control Low noise levels — unobtrusive in high-occupancy environments
The Comfort Circle Cassette delivers heating, cooling and ventilation from a single, discreet ceiling-mounted unit — fitting perfectly within a standard 600×600mm ceiling grid. The Air2Air Heat Recovery System captures up to 80% of the heat from outgoing stale air and uses it to warm incoming fresh air, dramatically reducing the energy cost of ventilation while maintaining superior indoor air quality.
BENEFITS
Recovers up to 80% of heat from outgoing air CO₂ demand-controlled ventilation Summer bypass for free cooling Compatible with AHUs and complete climate systems
