Maintenance of refrigeration coils is an important step in keeping your plant working efficiently. The above picture is a refrigeration coil that was in desperate need of cleaning.
What are some signs that you might have a dirty coil?
- Drying time has become longer
- Solvent usage has gotten worse
- Have more waste water (the coil will freeze and become a block of ice, then thaw and you end up with more waste water)
- The low side refrigeration gauge will read under 5 on the gauge.
- Your operator will become frustrated and let you know it.
To make sure you don’t need to worry about the above signs, Dry cleaning manufacturer’s recommend pulling the coils once a year and flushing them with water.
Maintenance of the disc filters are also over looked by most. Here are some signs it’s time to clean them:
- Machine is two years old and you have never cleaned them
- Filter pressure is 25 – 30 psi, you still them, and pressure id back up in days.
Maintenance of the base tanks on a hydrocarbon machine is also important. Lint builds up and moisture gets trapped which then can lead to bacteria breeding.
Base tanks should be cleaned once a year. Here are some signs to look for to denote it’s time to clean:
- Plant and clothes smell like rotten socks or baby vomit. (shows up in cottons first).
People come in your plant and tell you there’s an odor in your plant or my clothes smell rotten. Your in the plant all day and as a rule, you can’t smell it. A fresh nose can, take the person serious. Remember, N-ta-germ is a great protect against the bacteria.
Maintenance of the water separator once a month is also very important. You would only use deodorant once a week, consider a deodorant for your customers clothes!
