Frequently Asked Questions
How does the WALLER series work?
It recovers heat from the exhaust air and transfers it to the incoming fresh air via a heat exchanger.
Typical recovery efficiency is 70-90% depending on the type of exchanger (plate, rotary, or cross-flow).
What airflow is it designed for?
See "Airflow" in the technical table: typically 500-10,000 m³/h.
The airflow should be sized based on the room volume and the hourly air changes required by regulations for the activity performed.
Does it reduce air conditioning costs?
Yes, by recovering heat (or coolness in summer), 50-80% of air treatment costs can be saved.
The economic payback depends on annual operating hours and energy costs. For continuous industrial use, it is typically 2-4 years.
What maintenance does it require?
Periodic filter cleaning (3-6 months) and annual heat exchanger inspection.
Krollit supplies original replacement filters. For plate heat exchangers, cleaning requires disassembly and washing with specific products.
What power supply does it require?
See "Voltage" and "Power" of the fan motor: typically 230 V single-phase for small units, 400 V for industrial units.
Models with EC motors consume less and allow modulated flow regulation based on demand.
