Thermographic Diagnostics in Refrigeration: Testo Launches a Free Training Webinar

Thermography is becoming an increasingly valuable ally for those working with refrigeration systems. Testo has developed an online training session specifically on this topic, open free of charge to installers, maintenance workers, and refrigeration technicians who want to add an indispensable diagnostic tool to their professional arsenal.

Save the date: Wednesday, April 29, from 4:00 PM to 6:00 PM . The meeting is titled " Basic Course in Thermography and System Applications ."

Why thermography is of interest to the world of cold storage

In refrigeration systems, detecting a problem before it becomes a failure saves time, energy, and money. Thermal imaging allows for precisely this: it reads the thermal signature of components and circuits without shutting down the system and without direct contact, identifying what would otherwise be invisible to the naked eye.

The concrete applications in the refrigeration sector are numerous:

• compressors working outside the temperature range
• refrigerant lines with compromised insulation or leaking sections
• evaporators with abnormal ice formation or ineffective defrosting
• dirty or unevenly ventilated condensers
• Overheating terminals, contactors and electrical panels
• cold rooms and refrigerated display cases with thermal bridges or worn seals

In a context where the energy efficiency of refrigeration systems is under scrutiny—both from a regulatory and operating cost perspective—predictive maintenance based on thermal analysis represents a competitive advantage for installation and service companies.

What you will learn in the two-hour course

The webinar is intentionally focused on practical issues. It begins with the fundamentals of thermography and moves on to the practical aspects technicians encounter on construction sites or during on-site interventions.

The main contents concern the interpretation of thermal images (what the colours and gradients returned by the thermal camera really mean), the criteria for choosing the right instrument for the type of system to be analysed, and the methods for recognising the most frequent anomalies in refrigeration systems and their control panels.
