SIMULEX · LIVE DEMO

Try it yourself — distance × UV dose

A live mini-version of the Simulex calculation logic — real physics (inverse-square law, scientific D-values). The full Simulex app uses 3D ray-tracing across a large pathogen and substrate library; this is just a taste.

This demo uses simplified inverse-square math and assumes the slider value is UV-C radiant power (not electrical wattage). Real UV lamps have reflectors and line-source geometry — at short distances, intensity is usually higher than shown here. The full Simulex app computes 3D ray-tracing plus lamp geometry and lifetime decay.

Real-World Use Cases

See how engineers use the simulator to solve concrete UV problems

Water Treatment Plant

The Problem: You need to ensure 99.99% E. coli inactivation in a 500 m³/h drinking water system.
The Simulation: Enter your pipe dimensions, select E. coli, place UV-C lamps — the simulator shows you exactly how many lamps you need and whether your target log-reduction is achievable.
Plan Water UV System

Adhesive Curing Line

The Problem: Your LOCTITE 3311 adhesive needs UV curing but you're not sure which lamp wavelength and exposure time to use.
The Simulation: Select your substrate from the database, choose between LED and mercury lamps, and get the exact curing time and dose needed.
Simulate UV Curing

HVAC Air Disinfection

The Problem: You're designing UV-C disinfection for a building's air handling unit and need to size the system correctly.
The Simulation: Define your duct dimensions and airflow rate, select target pathogens, and validate that your lamp configuration delivers sufficient dose.
