Cleaning Fluid/Flushing Fluid For Heat Transfer Systems
Designed for Cleaning Large Systems More Economically with a High Flash Point.

 

Benefits of MultiTherm PSC Plus®

  • More Economical for Large Systems

  • Higher Flash Point than other typical System Cleaners

  • Non-Corrosive, Non-Toxic and Non-Hazardous material

  • Designed to breakdown sludge and stay in suspension for
      easy removal or filtration. System can be operated up to   550ºF/288ºC.

 

Purpose:
MultiTherm PSC Plus® Cleaning Fluid is designed for use in general maintenance of larger heat transfer fluid systems. MultiTherm PSC Plus® can be used with the Heat Transfer Fluid that is currently in the system or new flush fluid.

It is formulated to breakdown the sludge deposits and resin residue as a result of the detergency. MultiTherm PSC Plus® Cleaning Fluid is formulated to be compatible with all MultiTherm® Heat Transfer Fluids as well as most others so that small residual amounts left in the system will not cause a problem.

 

Application Without Filter:

  1. To prevent plugging, remove all Y-strainer elements.

  2. Remove and replace 3-4% of heat transfer fluid in the system with MultiTherm PSC Plus®.

  3. To clean Expansion Tank, open warmup valves to allow MultiTherm PSC Plus® to circulate through the tank as well.
    Note: It is recommended that you have a Nitrogen blanket on the expansion tank.

  4. System should be operated between 110°F to 550°F (43°C to 288°C).

  5. Fluid with MultiTherm PSC Plus® should be circulated for a minimum of 24 hours or up to 48 hours depending on level of sludge build-up in the system.

  6. Drain system of all the fluid as quick as possible at about 150°F (65°C). All sludge and particulate in the system will stay in suspension at this temperature.

  7. MultiTherm recommends flushing the system with MultiTherm FF-1® flushing fluid. This is to remove all the residual detergent, sludge and particulate left behind in system after draining.
    Note: If there is greater than 2% of residual cleaning fluid left behind and you drop the temperature of the system below 150°F (65°C), there will be additional carbon particulates dropping out of the fluid due to active detergent molecules.

  8. Completely refill with MultiTherm® Heat Transfer Fluid and restart by using recommended start-up procedure.

  9. Finally, we recommend that you walk the entire systems and check for leaks thay may have been a result of cleaning.

 

Application With Filter:

  1. To prevent plugging, remove all Y-strainer elements.

  2. Install a 100-micron cartridge in filter, or the largest one you have.

  3. Remove and replace 3-4% of heat transfer fluid in the system with MultiTherm PSC Plus®.

  4. To clean Expansion Tank, open warmup valves to allow MultiTherm PSC Plus® to circulate through the tank as well.
    Note: It is recommended that you have a Nitrogen blanket on the expansion tank.

  5. Change Filter Cartridges as required removing sludge and contaminates. As particles decrease, change cartridges from 100-micron to 50-micron down to 10-micron.

  6. System should be operated between 110°F to 550°F (43°C to 288°C).

  7. Follow same steps 5 through 9 of application without filter.
