For a 12-story office building in a mixed-use development, we usually spec the 16,000 m³/H unit to handle the lobby and lower two floors, while the 10,000 m³/H units serve the upper floors — and that distribution pattern cuts ductwork costs by roughly 15%. We've shipped units as small as 1,500 m³/H for a small restaurant's kitchen exhaust recovery (usually 20 days or so from order, but confirm lead time for custom voltage).
What it does is pull stale indoor air through one side of a plate exchanger while incoming fresh air passes on the other, transferring up to 75% of the heat energy. The 'W, V' guide rails in the core create a labyrinth seal that keeps cross-contamination below EPA thresholds for commercial kitchens. So the efficieny number isn't just marketing — it actually matters for LEED points and annual HVAC load calculations.
Construction is galvanized sheet througout — which most buyers go with over stainles because it's corrosion-resistant enough for wall-mount in a parking garage or rooftop, but doesn't add the 30% weight penalty that 304 would. Noise stays under 65 dB standard, though we can drop it to 55 dB with deeper acoustic insulation on the supply side. That's a good detail a buyer might miss: the standard baffles work for office common areas, but for hotel guest rooms, go with the quiet option explicitly.
Also, the wall-mount brackets accept our standard 3/8-inch threaded rods if you're hanging form I-beams, but the window-mount kit uses a custom extruded frame — basically $150 upcharge per unit (check lead time as it's not always in stock). 380/400 VAC is pretty much standard for European commercial projects; for North American 480 VAC, you'll need to specify at quoting. The design lifetime is 20+ years, but the gaskets around access panels should be replaced every 5-8 years depending on temperature cycling.
15-month warranty is what our company offer, though most buyers in this segment write their own commissioning specs anyway. One thing this actually isn't suited for: swimming pool dehumidification — the salt and chlorine from pool air will accelerate corrosion on the galvanized inner walls way faster than a standard office enviroment would. For that, you'd want an AluZinc or full polymer exchanger (and we usually push those customers to the competitor who makes them, because we don't do custom materials under 50 units).
We typically require a minimum order of 5 units for the HXF series, though we can discuss smaller quantities for first-time buyers or sample orders.
Yes, the HXF series is UL certified, along with CE, CCC, and RoHS, so it meets standards for both US and international installations.
We can customize the HXF series to fit specific airflow needs beyond the standard range, but it depends on your project specs—just let us know the required capacity and we'll check feasibility.
Standard HXF units typically ship within 3-4 weeks after order confirmation, though custom orders may take a bit longer depending on the modifications.
Store it in a dry, indoor area with temperatures between -10°C and 50°C, and keep the packaging sealed to avoid moisture or dust buildup on the galvanized sheet construction.
