3,000 hours. Level 10. ≤ 0.01% surface corrosion.

That's the result recently achieved by our Bluefin coated coils in a salt spray test conducted in accordance with ASTM D1654-2008.

This is the highest possible rating for corrosion resistance.

Bluefin coated coils are also a standard supplier across all of our heat exchangers.

For Consultants, Contractors and Building Owners, this means greater confidence in the long-term durability and performance of equipment, particularly in coastal, humid and other corrosive environments where coil protection is critical.

Acoustic testing matters, especially for air handling units.

Noise performance is critical for AHUs, influencing comfort, compliance, and overall building performance. Accurate testing ensures your units deliver the quiet operation your customers expect.

That’s why having access to an ISO‑certified acoustic facility, and at a size capable of handling full‑size AHUs, makes all the difference.

- Reliable, repeatable noise data
- Independent, ISO‑certified accuracy
- Confidence in meeting project noise criteria
- Credible performance claims backed by real testing

Our test chamber allows full‑unit testing under realistic conditions, giving you results you can trust, every time.
