Custom glycol blends premixed to your specifications
Getting the blend you need for your system can be a big deal.
Blending on site is labor intensive and requires someone strong in math and fractions who is precise with measuring fluids. You also need space to mix a large volume of fluids, which can be a huge challenge. And for optimal fluid performance, the quality of the dilution water matters too.
Premixing is necessary to ensure that the concentration percentages are appropriate for your system to function correctly.
Enter Deppmann. We can provide you with propylene and ethylene glycol premixed with high quality Deionized Water to the specific concentration you need for your system. Need 30%? 40%? You’ve got it.
