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 and someone who is precise with measuring fluids. You also need some place to mix this large volume of fluids, which can be a huge challenge.

However, premixing is necessary to ensure that the percentages are appropriate for your system to function correctly so you’ve really got to do it.

Enter Deppmann. We can provide you with propylene and ethylene glycol premixed with DI water to the specific percentage you need for your system. Need 40%? You’ve got it. Need 30%? We’ve got you covered.

R.L. Deppmann will blend and mix what you need and deliver your custom glycol blend right to your door. It doesn’t get easier than that!
