Increasing UV Reactor Efficiency since 2001.

Proven Success

Global Acceptance

UVCalc® has been sold on all continents and is used in more than 20 countries.

Unique Advantage

The only software of its kind that gives major reactor design advantages.

Cost Effective

Saves thousands of dollars that would have been spent testing.

Easy to Use

Takes advanced applied mathematics into a simple to use interface.


UVCalc® is now available in a convenient online format, where the user with internet access can access the software from anywhere. Enter parameters online and then receive the results in a downloaded file within a minute or two.

UVCalc Online can be used to model UV reactors from a simple 1­lamp annular reactor to complex multi­lamp reactors. Both low pressure (monochromatic) and medium pressure (polychromatic) UV lamps can be used.
