Dowtherm™ SR-1 and Dowfrost™ HD are the glycol products of choice

Let’s face it. In construction trades, price is always a consideration. When you compare cost and value, we believe that Dowtherm SR-1 and Dowfrost HD are the best glycol options on the market today for your HVAC system. Here’s why:
  • Dow is arguably one of the biggest players in the chemical production world. Using products backed by a global, environmentally-responsible company gives our customers peace of mind.
  • In our opinion, Dow quality just can’t be beat. They NEVER use re-manufactured products.
  • The inhibitor chemical package in these products does a great job of preventing pipe and equipment corrosion.
  • Dow’s training materials and industry education are top notch.
These products are the real deal, which is why we use them and believe that you should have them in your HVAC system.

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 27%? We’ve got you covered.

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