Application Frigoriste [hot] May 2026

The interface is clearly designed by engineers for engineers. Buttons are large enough for gloved fingers, and the text is crisp. However, the learning curve is steep. If you are a first-year apprentice, you will be lost. There is no "wizard" mode that explains why you need to enter liquid line length or ambient temperature. You either know what you’re doing or you don’t. I appreciate the lack of hand-holding, but a few embedded tooltips wouldn’t hurt. This is why you buy the app. The pressure-temperature (PT) chart database is astounding . FrigoMaster Pro supports over 45 refrigerants, including legacy gases (R12, R502), modern HFOs (R1234yf, R1234ze), natural refrigerants (R290, R600a, R744/CO2), and even obscure blends like R407A and R427A.

Yes – to every journeyman and contractor. For students, buy the monthly subscription for your exam month, then cancel. For hobbyists, stick with free alternatives. For the pros: this is the Leatherman of refrigeration apps. application frigoriste

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).
