UVC dimerization

When UVC light is described as “inactivating” microorganisms, the process is very different from crushing or burning. It’s a molecular change powered by light.

How It Works

  • DNA/RNA absorption: Microorganisms absorb UVC energy.
  • Photodimerization: Bonds between nucleic acids break or rearrange.
  • Result: The genetic “code” is scrambled, stopping microorganisms from replicating.

Why It’s Powerful

  • Works quickly and without chemicals.
  • Reaches both direct surfaces and shadowed areas with Tru-D®’s sensor-based automation.
  • Requires no heat, moisture, or pressure—making it versatile across environments.

By stopping microorganisms from replicating, Tru-D® devices harness light as a safe, effective and chemical-free solution.
