Topvex SR description
Systemair Topvex SR is a heat-recovery ventilation unit (HRV) that continuously supplies fresh air throughout the building while recovering heat from the exhaust air. Systemair is a Swedish manufacturer known for its professional central AHUs and Nordic construction tradition. The Topvex SR model is designed specifically for small and medium commercial buildings, where both energy savings and quiet operation matter.
How Systemair Topvex SR works
The unit draws fresh air from outside while simultaneously extracting stale air from the rooms. A counterflow plate heat exchanger transfers heat from the exhaust air to the incoming fresh air without the two streams mixing. The result is fresh, filtered supply air that in winter arrives at almost room temperature. This significantly reduces heating costs — often 30–50% compared to natural ventilation. The Topvex SR series covers airflows of 300–3000 m³/h and suits a small office, restaurant, kindergarten or shop, for example.
Energy efficiency and indoor climate
Systemair Topvex SR suits objects of 300–3000 m³/h and is designed to deliver the highest possible heat recovery. Supply air is filtered — typically with an F7 or better filter — which stops pollen, dust and fine particles (PM2.5). It is especially valued by allergy sufferers and families with young children. Filtered air keeps indoor CO₂ levels low, reduces moisture in bathrooms and kitchens, and prevents mould.
Control and automation
Standard equipment includes the Systemair NaviPad touch panel and a Modbus interface. This means the unit runs only as much as needed — saving electricity and extending filter life.
