Cleaning fluid for Hot Oil Temperature Control Units
The new Paratherm SC® system cleaner liquid is expressly formulated to dissolve and suspend sludge and carbon lumps frequently produced in hot oil temperature control units where petroleum or glycol-based heat transfer fluids have been used. The SC fluid is a multi-component synergistic liquid that is compatible with any mineral oil-based thermal fluid, and many of that synthetic fluids as well. Used warm (150°F max) or cold, it provides excellent sludge-removal properties across the temperature range.
The Paratherm SC® liquid can be reused after solid matter drops to the bottom of the container or is filtered out. And when it is finally spent, the fluid can be combined with other common parts-washing liquids and disposed of conventionally.

Instructions for Use
NOTE: Cleaning and maintaining your hot oil temperature control system will be a lot easier if you replace the drain plug with a valve mounted externally.
Drain existing fluid while warm if possible.
Replace drain plug with ball or globe valve.
Bottom-fill system with fluid so that reservoir tank has approximately 1″ to 2″ of fluid in bottom, or enough to start pump.
Circulate cold for 3 to 4 hours. If reservoir needs to be cleaned, run discharge hose into tank through vent or open vent to agitate fluid in tank.
Let system soak overnight.
Start system up and circulate from 1 to 4 hours. Fluid works faster when warm. Heat to max of 150°F if possible.
NOTE: Do not circulate through expansion tank while system is hot.
If required, turn off heat and allow fluid to cool with pump running.
When fluid temperature reaches ambient (80°F), begin to drain fluid while pump is still operating. Shut off pump when pressure begins to fluctuate. Continue draining system.
Refill system with Paratherm fluid or any compatible mineral oil-based product. Set temperatures at 150°F and circulate for 1-2 hours. Shut down and drain immediately. Repeat if odor still present.
Refill system with Paratherm heat transfer fluid and put unit back into service.
The SC liquid is available in 5-gallon pails and 55-gallon drums. Shipment is via UPS and motor freight, and is shipped same-day if we have your purchase order by 10:00 AM.
Our technical expertise is available to you in the conceptual stage, during planning and design, and through system construction, start-up and operation. We want to work closely with you in the recommendation of proven thermal fluidsystems, components, supplies and procedures.
We also advise on system cleaning and repair,should these become necessary. And if yourapplication calls for fluids that we are unable toprovide, Paratherm will assist you with the names and phone numbers of competitors’ engineers that can help.
Paratherm has available technical data sheets covering a variety of thermal fluid and systemtopics including fire prevention, system performancetracking, recommended components,draining, flushing and charging and fluid analysis, among others. We’d be pleased to forward these to you upon request.
