UV Simulator

Design UV systems with real physics — not guesswork

Plan UV-C disinfection or UV curing projects in minutes. Place lamps in 3D, simulate dose distributions with ray-tracing, and get concrete results: kill rates, curing times, Go/No-Go assessments.

Two Simulation Modes

Choose your application — the simulator adapts its physics engine, database, and UI to your use case

UV-C Disinfection

Calculate pathogen kill rates for air, water, and surface disinfection. Select target organisms, place UV lamps in 3D, and get a Go/No-Go assessment.

  • 97 pathogens with scientific D-values
  • Air, water & surface media
  • Go/No-Go traffic light system
  • Multi-lamp placement in 3D

UV Curing

Simulate curing times for adhesives, coatings, and sealants. Match wavelength compatibility and calculate optimal exposure for your substrate.

  • 33 industrial substrates (LOCTITE, DELO, Dymax...)
  • Wavelength compatibility check
  • Curing degree calculation
  • LED & mercury lamp comparison

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.

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.

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.
