Frequently Asked Hoval Air-Handling Questions
What is the difference between RoofVent and ProcessVent units?
RoofVent units are designed for central supply and extract ventilation in buildings such as offices, schools, and retail spaces. They are typically roof-mounted and provide fresh air with high-efficiency heat recovery. ProcessVent units are intended for industrial and process applications, where specific temperature or humidity control is required, such as manufacturing halls or warehouses.
Do Hoval systems support heating and cooling as well as ventilation?
Many RoofVent and ProcessVent configurations can be fitted with integrated heating and cooling coils. This means a single unit can supply fresh air, recover heat, and provide temperature control - ideal for projects seeking an all-in-one air-handling solution.
How efficient are Hoval air‐handling systems?
Hoval’s RoofVent and ProcessVent units feature high-efficiency heat recovery. Some RoofVent models potentially offer up to 86% thermal recovery under optimal conditions, while others may typically deliver figures in the high 70s, depending on model and flow. Efficiency depends on system selection, matching flow rates, and proper installation.
Can these systems integrate with building management systems (BMS)?
Yes, Hoval roof and process ventilation units are equipped with advanced control systems (such as TopTronic® C) that support sensor feedback, time-based control, variable speed drives, and can interface with BMS for monitoring, scheduling, and optimising performance.
What do commercial ventilation and air-handling systems actually do?
A commercial ventilation and air-handling system provides a continuous supply of clean, conditioned air while removing stale or contaminated indoor air. It typically includes fans, filters, heat-recovery components, and optional heating or cooling coils. By balancing fresh-air intake with exhaust, such systems maintain comfortable temperatures, healthy humidity levels, and good indoor air quality. Essential for offices, schools, healthcare facilities, and industrial spaces.
Why choose a dedicated air-handling solution over simple extract fans?
While extract fans only remove air, a full air-handling unit (AHU) both supplies and filters fresh air and can recover energy from exhaust air. This means lower heating and cooling costs, more consistent temperature control, and importantly - far better air quality. A dedicated AHU can also integrate with building management systems, provide precise airflow regulation, and scale to the needs of large commercial or mixed-use buildings, providing benefits that basic fans simply can’t match.
