Refrigerant System Optimization (RSO) - RSO removes oil that has leaked from the compressor, and is now adhered to the interior inner wall of the evaporator and condenser coils. This oil acts as an unseen insulator for your refrigeration heat exchange surfaces. This makes heat transfer less efficient.

Oil in your refrigeration equipment:

    • Reduces Energy Efficiency
    • Reduces System Lifetime
    • Increases Maintenance Costs

With RSO, your refrigeration system can increase thermo-conductivity of refrigerant by 25.5% and increase the efficiency of oils, metals, and the flow of refrigerant. RSO is effective on all refrigeration systems including cold storage, ice production, and HVAC systems. RSO will also:

    • Clean coil system 
    • Prevent oil from reattaching to the surface
    • Return oil to filter/oil sump
    • Aid in lubricating compressor
    • Protect HVAC system from degradation





Applied exclusively by experienced HVAC Armor Certified Professional Applicators. HVAC Armor RSO is an affordable green initiative that increases refrigeration efficiency.
