Glass Wool Production
A breakdown without production losses
To produce glass wool from melted glass, low-pressure air at 2.5 bar g is used. For this process the air must not be polluted; this means the air must also be oil free. Therefore the use of oil-injected or oil-lubricated compressors is not an option.
When the main compressor in a glass wool manufacturing plant broke down, replacing its air capacity had to be done quickly because the standby supply was not sufficient for full production to continue during the overhaul period.
Rental compressors take over
Four oil-free compressors in parallel were quickly installed into the air supply; separate air-cooled after-coolers were used to reduce the temperature of the compressor air.
After the main compressor had been repaired and overhauled, the rental installation was quickly removed. In case of future need, it was decided to leave the emergency flange connection in place to allow for an even faster installation next time!
