Topvex SX/C – Energy efficient air handling unit with counter flow heat recovery
Available in three sizes with air flows up to 3.300 m3/h
Topvex SX/C is a series of air handling units designed to meet the increased demands of energy efficiency according to ErP 2018. As one step they are equipped with efficient counter flow heat exchangers that gives over 80% dry efficiency (EN308).
To ensure low energy use, even during summer, the units heat recovery module are provided with automatic by-pass that is capable to cover 100% of the air flow. The inbuilt control system includes energy saving functions such as cooling recovery, free cooling, summer operation, yearly operation calendar, outdoor compensated air flow control etc. Demand control ventilation can be used with CO2 presence, moisture or air quality sensors.
Systemair offers Topvex SX/C with two heating alternatives, electrical and water, the last one in two power variants.
In standard performance Topvex SX/C is designed for step less voltage control, but CAV and VAV control is available as an accessory.
