During continuous thermal shock testing, rapid temperature swings inevitably cause moisture to freeze on the equipment's evaporator coils. Left unchecked, this frost buildup acts as an insulator, drastically reducing cooling efficiency and compromising test accuracy. Managing your chamber's defrost cycles is vital for long-term system health. In this guide, ITM-LAB explains how to properly configure your defrost frequency, comparing time-based and cycle-based settings to help you maintain optimal testing performance.
