Energy Saving Cross Flow Heat Exchanger Core for Ventilation Systems

The efficiency range sits between 57% and 76% depending on the model, and we've seen it handle air volumes from 200 up to 6000 m³/h. It basically does what a cross flow core is supposed to — recovers heat without mixing the airstreams, which keeps the building comfortable without wasting energy. Static pressrue runs from 40 to 240 Pa, so it's pretty for different duct setups. The fin pitch can vary from 2.5 to 10 mm (usually 4 mm or 6 mm are what most buyers go with), and the thickness is around 0.1 to 0.3 mm depending on if you pick stainless steel or alumnum.

Our project manager for a mid-sized office block specified the H Series because the noise level caps at about 66 dB(A), but in quieter zones it stays closer to 29 dB(A). That matters when you're running it in a conference room or a meeting area — it's better than some of the alternatives we tested. Tempearture resistance tops out at 280°C for the high-temp variant, which is fine for most industrial heat recovery application; 150°C or 220°C cover the standard setups.

They're used in commercial ventilation, industrial workshops, and even machine rooms with specific air quality needs — but you wouldn't put one in a small residential unit, the air volume range just doesn't match. The counter flow option is tighter on efficiency (think around 80%), but cross flow is easier to maintain and costs less per unit. Either way, the fins are thin enough to pack a lot of surface area into a compact core.

We usually get a CE certificate and an ISO 9001-2008 compliance document with each shipment; warranty is a standard one year. Lead time is roughly 20 days or so for 50 units, but confirm with the suplier if you're north of 100. One thing nobody talks about is the foam density inside housing — we had to swap out a spec once because of that it trapped condensation in a colder climate, so check your dew point if you're below freezing.

350 units, our typical order, take about 4 weeks including the holiday shutdown. They run with a MOQ of 10 units for the standard sizes, but custom dimensoins are available if you're patient — delays aren't unusual for fin pitch changes. Power consumption is 0.016 to 1.8 kW, which basically means you can run the smallest unit on a standard wall outlet.

People who spec these are usually facility managers or HVAC contractors who've had bad luck with spinning wheels or plate exchangers that freeze up. Anyway, the H Series is a solid compromise between heat recovery rate and simplicity — the cross flow design doesn't have moving parts, so it's low maintenance. And the price per cubic meter of airflow is actually better than some of the cheaper riveted versions we looked at early on.
