FAQ

Air Handling Units — frequently asked

Custom AHU or packaged rooftop unit?

Below ~15,000 m³/h and standard air quality, packaged rooftop units usually win on install cost and lead time. Above that, or for hygienic / clean-room duty, custom AHUs allow the right coil rows, filtration stages, heat recovery and casing class.

What EUROVENT / EN 1886 class should I specify?

Commercial offices: casing L2, thermal T3, thermal-bridge TB3 is a reasonable baseline. Hospitals and pharma: L1, T2, TB2 with EPA/HEPA filtration and hygienic construction (VDI 6022, EN 1946).

Is a heat recovery wheel always worth it?

In climates with meaningful heating hours and dense fresh-air demand, yes — payback is typically 2–4 years. Skip only where fresh-air ratio is very low or hygienic segregation forbids cross-contamination (use run-around coils instead).

How fast can ColdMatch source AHUs?

A structured brief goes to shortlisted OEMs within 48 hours. Standard AHU packages typically quote in 1–2 weeks; custom hygienic AHUs 3–4 weeks.
