- F-Gas Phase-Down Regulation
- A regulatory mandate aimed at progressively reducing the consumption and production of hydrofluorocarbons (HFCs) with high global warming potential. In industrial thermal engineering, it drives the transition to low-GWP refrigerants and natural alternatives to comply with environmental standards.
- FDA 21 CFR Compliance
- Adherence to United States FDA regulations governing food, drug, and medical device manufacturing, particularly regarding the validation of electronic records and signatures. In industrial thermal engineering, it ensures that process control data is tamper-proof and fully traceable for consumer safety.
