Frequently Asked Questions
Our spent antifreeze is typically 40-45% ethylene glycol by volume and 60-65% water. Customers want new engine coolant with 50% ethylene glycol. Is that a problem for EET’s Coolant Recycling System (CRS)?
Not at all! After EET’s CRS removes metals, inorganic contaminants and dissolved salts, a simple refractometer measurement will rapidly establish the percentage of ethylene glycol and how much concentrate glycol needs to be added. Alternatively, an evaporator may be used to remove excess water.
Why should I bother with recycling antifreeze when I can dispose of spent antifreeze in the sewer with a modest upcharge from the local Publicly Owned Treatment Works?
If you're disposing of spent antifreeze by pouring it down the drain, you are literally throwing money away. The best reason we can give you for recycling antifreeze is that it will save you money and increase your company’s profitability, and is the environmentally sound thing to do.
Does it take a skilled operator to recycle antifreeze with EET’s CRS?
No. We have designed the system to be very simple to operate and the operating manual provides step-by-step instructions and is well illustrated.
Some of my customers have a requirement for certain
corrosion inhibitor packages for use in their machinery and
vehicles. Is this a problem?
No. EET offers a variety of OEM additive chemistries for use with the CRS.
What size footprint does the CRS require?
The CRS Model 75 needs about 200 square feet of space. Additional space is needed, depending on your desire to procure optional mixing tanks and your preferred batch sizes.
