Polishing Cleaning Ball for HVAC Heat Exchanger Systems (PL091 / P091)
Description
PL091 (P091) polishing cleaning balls are sponge-type cleaning balls designed for air conditioning and refrigeration heat exchanger systems. They are used in low-salinity water environments for stainless steel and titanium tubes.
These cleaning balls are coated with an external polishing agent, which improves cleaning performance while protecting the tube surface.
Application
Suitable for:
Stainless steel tubes
Titanium tubes
Heat exchangers in air conditioning and refrigeration systems
Low-salinity water cooling systems
Especially suitable for HVAC heat exchangers operating in low-fouling conditions.
Cleaning Frequency
According to recommended operating conditions and actual application cases.
Features
External polishing agent coating cleaning ball
Suitable for stainless steel and titanium tube systems
Stable elasticity and good recovery performance
Designed for HVAC and refrigeration equipment
Helps maintain heat transfer efficiency and reduce fouling
PL091 type is not recommended for already clean stainless steel and titanium tubes.
