HFE Chemistry: Standing the test of time
What is HFE Chemistry?
HFE stands for hydrofluoroether—a class of advanced cleaning solvents developed to replace ozone-depleting compounds such as CFCs, HCFCs, HFCs, and PFCs. HFEs are colorless, odorless, and tasteless liquids that closely resemble water in appearance, but offer exceptional engineered fluid performance in precision cleaning and vapor degreasing.
With a high molecular weight, HFE compounds remain in the atmosphere for less than two weeks and have zero ozone depletion potential (ODP). Most BestSolv® engineered fluids utilize HFE-based chemistry to ensure maximum compatibility with existing solvent cleaning systems while supporting global sustainability goals.
HFEs also feature low global warming potential (GWP), allowing manufacturers to meet strict environmental standards without compromising on safety, material compatibility, or cleaning power.
HFO Chemistry: A Safer, Sustainable Alternative
BestSolv® Zeta and BestSolv® Omega fluids are engineered without PFAS, aligning with the strictest environmental regulations in the U.S. Formulated with HFO (hydrofluoroolefin) chemistry, these PFAS-free cleaning fluids deliver high cleaning performance and low environmental impact—no compromise required.
- ✅ No PFAS
- ✅ Low Global Warming Potential (GWP)
- ✅ Nonflammable
- ✅ Safe for Operators
- ✅ Long-Term Compliance
Common Applications for BestSolv® Fluids
BestSolv® Engineered Fluids are trusted across a wide range of industrial applications—especially for companies seeking a high-performance, compatible alternative to 3M™ Novec™ solvents. These applications include:
Vapor Degreasing
Removes oils and contaminants using heated solvent vapor.
Solvent Cleaning of Industrial Parts
Cleans precision components without residue.
Cleaning Oxygen System Parts
Suitable for oxygen-compatible degreasing.
Movie Film Cleaning
Gently removes dirt without damaging archival film.
Other Precision Cleaning Applications
Ideal for sensitive, high-spec surfaces.
Latent Fingerprint Processing
Reveals hidden fingerprints on various surfaces.
Forensic Analysis of Bloodstains
Preserves and highlights trace evidence.
High Voltage Testing
Ensures insulation and safety in electrical systems.
Dielectric Cooling of Power Electronics
Non-conductive cooling for heat-sensitive components.
Fire Suppression
Used in clean agent systems for sensitive environments.
BestSolv® Engineered Fluids Replace 3M™ Novec™ Fluids
Best Technology offers three types of replacement fluids for 3M™ Novec™ products:
Exact Molecule
BestSolv® Exact Molecule (also sometimes referred to as “Direct Molecule” or “Chemically Identical”) replacements match 3M™ Novec™ chemically, simplifying validation with identical properties. Classified as PFAS under the U.S. EPA’s definition, they ensure a smooth transition for industries needing minimal process changes.
Similar Molecule
BestSolv® Similar Molecule replacements use a different HFE molecule than 3M™ Novec™ but offer similar properties. Unlike Novec™, they are not classified as PFAS under the U.S. EPA’s proposed definition.
This option is a cost-effective, environmentally friendly Novec™ alternative. BestSolv® replacements also provide significant savings, with similar molecule versions costing less than exact molecule replacements.
Next-Gen PFAS Free
BestSolv® Next-Gen PFAS Free replacements use HCFO/HFO-based fluids instead of the HFE chemistry used in most 3M™ Novec™ products. The next-gen PFAS-free products comply with strict PFAS-free regulations in Minnesota and Maine, ensuring a sustainable alternative.

Solvent Cleaning with BestSolv® Engineered Fluids
Why Solvent Cleaning?
Thanks to their low surface tension, BestSolv® Engineered Fluids penetrate tight spaces and intricate geometries, delivering a deeper, more thorough clean. Once contaminants are removed, the fluids drain easily without becoming trapped in small crevices.
The fluids evaporate quickly and leave behind minimal non-volatile residue (NVR)—unlike aqueous solutions, which can cause staining or deposit residues from water content. This results in faster drying, more efficient cleaning, and fewer issues with drag-out, ultimately reducing solvent loss and operational costs. For operations transitioning away from phased-out chemistries, BestSolv® also serves as a reliable 3M™ Novec™ replacement, offering comparable cleaning power with a reduced environmental footprint.
BestSolv® Formulations for Solvent Cleaning
Best Solv is distributed by Best Technology and is available in a range of formulations to meet diverse cleaning needs—from light-duty to heavy-duty applications.
Our “neat” HFE formulations consist of 100 % hydrofluoroether (HFE) or 100 % hydrofluoroolefin (HFO) for applications requiring maximum material compatibility, making them an ideal 3M™ Novec™ replacement for facilities moving away from phased-out chemistries.
Other formulations include additives for better cleaning performance. The most common additive to BestSolv® formulations is trans-1,2-dichloroethylene (t-DCE).
Note: t-DCE is distinct from trichloroethylene (TCE), a known hazardous solvent. BestSolv® products do not contain TCE.
