When it comes to data center cooling, performance and efficiency are only part of the equation—safety and compliance are just as critical. That’s why Inova is proud to share a deeper dive into how our NovaCool Rear Door Heat Exchanger (RDHx) earned its UL 62368-1 certification.
More than just a badge, this certification reflects NovaCool’s engineered resilience, especially under extreme operating conditions. In this article, we go beyond the announcement to walk you through the rigorous tests NovaCool passed, including a high-heat pressure resistance test with zero leakage.
Why UL 62368-1 Certification Matters for Liquid Cooling
UL is a globally renowned certification organization, recognized for its uncompromising standards and rigorous testing processes. Earning UL certification is not just a mark of compliance — it’s a symbol of trust, safety, and excellence acknowledged worldwide.
UL 62368-1 emphasizes identifying potential hazards and designing safeguards based on the energy sources present in NovaCool RDHx. It covers a wide range of safety aspects, including:
- Fire resistance
- Electric shock protection
- Overheating prevention
- Mechanical hazard mitigation
- Water intrusion protection (especially in systems involving liquid cooling)
NovaCool RDHx passed all the above evaluations in the UL lab, it demonstrates a commitment to safety, reliability, and innovation — making them more trusted by customers, integrators, and data center operators worldwide.
Putting NovaCool to the Test: G.15 and Beyond
One of the most rigorous parts of UL 62368-1 is section G.15, which evaluates the reliability of a product’s water circuit system under high stress.
- Our entire water circuit system, including internal piping, was placed in an oven at 87°C (188.6°F) for 14 consecutive days.
- Following that, it underwent a water pressure resistance test at 1.45 MPa—three times the normal operating pressure.
The result? Zero leakage.
This not only demonstrates mechanical integrity but also reinforces NovaCool’s ability to operate in high-temperature environments with no compromise to safety over time.
Certified on A Global Scale
In addition to UL certification, NovaCool RDHx has also achieved:
- CE-LVD, CE-EMC – confirming compliance with European Union safety, health, and environmental standards.
- FCC certification – ensuring electromagnetic compatibility in the United States.
With these credentials, NovaCool is ready for data center deployments around the world—meeting the demands of enterprise clients, hyperscale operators, and colocation providers alike.
Ongoing Confidence
All NovaCool RDHx units will continue to meet UL standards through UL’s ongoing surveillance and recertification programs. This means customers can deploy with confidence, knowing our commitment to compliance doesn’t end at certification—it’s continuous.
