By working at night, alternating fans and utilizing JPX-F from Jayne Products, a heavy duty cleaner, our industrial cleaning customers use a foaming procedure which cleans the fins while the unit continues to run. They have experienced as much as 40-degree improvement but the norm seems to be 25-30 F. The procedure uses a very small amount of liquid and produces copious amounts of foam.
Brief Outline of Procedure
- Turn off and tag out fin fan motor
- Block in fin fan inlets, and let cool.
- Foam each fan shroud enclosure from above and below if possible. Pay particular attention to directing foam to the corners of the shroud to cover fin fan area evenly.
- Use approximately 25 gallons per shroud. Wait 5-10 minutes then rinse with water spray from above.
Benefits of Online Fin-Fan Cleaning with JPX-F
- Cleaning of the exteriors will not require entry into the shrouds, no need for entry permits.
- No damage to tubes by personnel entering shrouds and walking on aluminum tubes
- No damage by improper use of high-pressure water, which will bend the aluminum fins.
- This system does a deep cleaning of the interiors of the tube banks that cannot be done using hydro-blasting equipment.
