Why only 3.5 stars? Because the is too conservative. For a 30m R290 line at -10°C evaporating, the app insisted I needed a 1-1/8" line, which is overkill and economically stupid. Experienced fitters will know to override it, but a junior tech might waste money on copper. The Load Estimator for cold rooms is basic – it uses rough rules of thumb (e.g., 150 W/m³ for a frozen room). For a serious design, you still need CoolPack or a manual J-calculation. This module is good for a quick sanity check, not for final engineering. F-Gas Tracker & Digital Logbook (5/5 – for compliance) If you work in the EU or any region with strict F-gas regulations (like the UK or Australia), this module is worth the subscription price alone. You can scan the barcode of a unit, log the refrigerant type, charge weight, and leak test dates. The app then generates a PDF report ready for inspection. It also tracks your company’s total CO2 equivalent and sends you push reminders for mandatory leak checks (3 months, 6 months, 12 months depending on charge size).
A Deep Dive into FrigoMaster Pro: The Indispensable, Yet Imperfect, Companion for the Modern Refrigeration Technician application frigoriste
The killer feature here is the . FrigoMaster Pro pairs seamlessly with most Bluetooth probes (Testo, Fieldpiece, UEi). The real-time graph of superheat drift over 15 minutes is a thing of beauty. One star deducted because the Bluetooth pairing process occasionally drops out when the phone goes to sleep, forcing a re-sync. Annoying when you’re on a ladder. Pipe Sizing & Load Estimator (3.5/5) This is the weakest link, though still decent. The pipe sizing tool uses the standard ASHRAE pressure drop method (1K per 10m for suction lines). You enter refrigerant, capacity (kW/TR), equivalent length, and suction/discharge temperatures. It spits out recommended line sizes and even calculates oil return velocity. Why only 3
