TOWER PERGE
Detergent Cleaner for Oil & Grease Contamination
DIRECTIONS FOR USE:
NOTE: Oil and grease contamination indicates a problem that requires corrective action.
Locate and identify the source of the contamination and take appropriate measures prior to
cleaning to insure that it is corrected. Possible sources are hydraulic heat exchanger leaks,
airborne sources, new metal piping, etc.
When cooling systems become contaminated with oil and grease, the TK SERIES reaction
media can become coated and insulated from the reactions necessary for proper
performance. In order to restore performance to the reaction media, it is necessary to
clean the contamination from the media and the entire system.
TowerPerge has been formulated specifically to remove petroleum based oil and grease
contamination and restore performance. TowerPerge is a combination of a strong
surfactant combined with a foam suppressant and an emulsifying polymer. The foam
suppressant is present in a controlled dosage and is effective in the control of excessive
foam. The use of additional foam suppressant will diminish the effectiveness of the
product.
For each column on your TK SERIES system:
1. Mix one pint of TowerPerge in five gallons of hot water and stir to mix.
2. Pour the solution into the cooing water reservoir and allow it to recirculate
throughout the entire system for two (2) hours.
3. After two hours, it is important to purge the system of emulsified oils and grease
from the system. If possible, dump the entire system and rinse the reservoir prior
to refilling. As an acceptable alternative, you may dump as much of the water as
possible and manually activate the filter backwash, every 30 minutes for a period
of four hours insuring that water clarity has returned. Failure to completely purge
the system will result in a breakdown of the emulsifier and redeposition of the oil.
After the system has been cleaned, you may notice that the scale removal rate has
increased and adequate precautions should be taken.
For serious contamination that involves visible oil films the procedure may require more
than one treatment, along with physically cleaning tanks, etc. Contact AEC, Inc. for
