Compressor Emission Solutions
T.F. Hudgins helps you meet the most stringent environmental requirements - today and in the future.

Zero-Emission Systems
T.F. Hudgins offers the first and only true zero-emission system for reciprocating compressors. Easily fitted to most existing equipment, these systems have proven to be ultra-reliable in reaching the most stringent attainment levels in virtually all environments.

Valve Restraint Upgrades
Many OEM valve restraints are the source of significant fugitive emissions.They can also allow valves to loosen while the compressor is running - a common,but serious reliability and safety issue. T.F. Hudgins offers valve restraints that secure valves more dependably. Plus they seal so effectively, they virtually eliminate leakage. Designs are available for easy retrofit to your compressors.

Ultra-Low-Leakage Packing
New packing and seal designs have been shown to dramatically reduce leakage in virtually all compressor services. Because these designs greatly reduce the amount of leaked gas that needs to be contained, product and efficiency losses are minimized. This improved performance may provide a significant savings.

Cylinder Component Upgrades
Unloaders, packing cases, compressor rods, wiper and partition assemblies - T.F. Hudgins offers both modifications and new, ultra-low emission designs for all of these emission sources. These solutions will enable you to both substantially reduce emissions and improve reliability.
