For optimal FrigoDep, never fill a commercial unit beyond 80% capacity. Overloading blocks the evaporator fan, creating "dead zones" where temperature rises above 41°F (5°C), entering the danger zone for bacterial growth.
Propane-based refrigerants are becoming standard. They require specific FrigoLec components (explosion-proof relays) and different FrigoDiag pressure charts.
The commercial refrigeration industry is moving toward IoT and predictive maintenance, but the fundamentals remain unchanged. Whether you are a supermarket maintenance manager, an HVAC apprentice, or a 20-year veteran technician, mastering the quartet of Frigobase, Frigodep, Frigodiag, and Frigolec will elevate your troubleshooting accuracy, reduce callbacks, and extend equipment life.
When you apply them in order, you don’t just fix the symptom—you solve the root cause. And in refrigeration, that’s the difference between a temporary patch and a permanent repair.

are a specialized suite of interactive educational software developed by KOTZA International
(often associated with the expert Patrick Kotzaoglanian). These programs are designed to train refrigeration technicians and engineers through simulation, troubleshooting, and theoretical application. Software Suite Overview
Each program focuses on a distinct pillar of refrigeration and HVAC systems maintenance:
: The foundational tool for beginners. It explains refrigeration and air conditioning basics through physical phenomena like water boiling or bike pumps. It includes a database of over 100 refrigerants and their thermodynamic properties. For optimal FrigoDep, never fill a commercial unit
: An "intermediate" level program focused on learning refrigeration troubleshooting. It allows users to simulate the performance of various cycles—including simple, cascade, and heat pump cycles—and modify parameters like compressor efficiency or evaporator temperature.
: A dedicated fault simulator. It randomly generates breakdowns for the user to diagnose, recording the technician's score and efficiency for each repair. It aims to help professionals identify malfunctions like leaks, overloads, or undercharges.
: Focused on electrical troubleshooting for refrigeration systems in both single-phase and three-phase circuits. It simulates electrical faults in air conditioning units, helping technicians diagnose common power-related failures. Key Features and Training Method Progressive Learning
: The software uses a step-by-step approach. For example, Frigodep features 28 stages with over 430 specific troubleshooting scenarios. Integrated Documentation : The programs are intended to be used alongside "Le Manuel du Dépanneur" When you apply them in order, you don’t
(The Repairman's Manual), a comprehensive 600+ page guide to HVAC and refrigeration maintenance. Performance Tracking
: The software automatically saves progress, displays scores, and provides real-time feedback with corrections for every diagnostic decision made. System Compatibility
: These are legacy tools originally designed for older Windows environments (Windows 95 through XP). Complementary Tools
