What Is a Witness Test and Why Is It Important?
A witness test is a key quality assurance step that allows customers to observe their Daikin Applied UK units being tested under simulated real-world conditions. Conducted in our state-of-the-art climatic chambers and testing facilities, these tests ensure that every system meets the exact specifications of your project.
For consultants, installers, and project managers, a witness test offers complete peace of mind, verifying that the equipment operates reliably under extreme ambient temperatures, varying load conditions, and mission-critical environments.
In large-scale HVAC projects—such as data centres, hospitals, and industrial facilities—witness testing is often a mandatory requirement. It guarantees that your system will perform optimally within the required temperature range, energy efficiency targets, and operational demands, ensuring long-term reliability and compliance with industry standards.
At Daikin Applied UK, we go beyond just manufacturing air conditioning and chiller systems—we deliver proven performance, reliability, and efficiency through rigorous testing and validation.
