Laser Chiller Sizing & Dew Point Anti-Condensation Calculator

Optical module internal condensation (dew formation) is the #1 killer of fiber laser diodes in tropical or desert climates. Calculate exact chiller heat dissipation and safe temperature setpoints.

1. Operational & Climate Inputs

Fiber Laser Optical Output Power

Workshop Peak Ambient Temperature (°C)

Workshop Relative Humidity (RH %)

2. Chiller Sizing & Dew Point Thresholds

Required Chiller Heat Dissipation 32.0 kW (109,200 BTU/h)

Ambient Air Dew Point (Td) 31.8°C (Condensation Risk!)

Safe Low-Temp Water Setpoint (Laser Source) 24.0°C (Requires Air-Conditioned Laser Enclosure)

Safe Room Water Setpoint (Optics/QBH) 32.0°C
