Our expertise

A partnership with the Envirotemp dielectric team goes far beyond the mere purchase of innovative fluids. Proprietary knowledge, expert service, dedicated support all infused with Cargill’s global supply chain logistics and local production adds indisputable value that will reap dividends for your company’s upcoming project.

Technical Support

With more than 30 years working with many types of dielectric fluids and more than a decade of experience with ester fluids, our technical team can pretty much answer any question and solve any issue. And, funny thing is, we love the challenge.


Change is not easy. That’s why we adhere to the same industry standards and processes your teams currently are familiar with and use every day. We try to minimize the change. Our team knows ester fluids inside and out. We will work with your teams to ensure they will be successful all the way through the process from designing new transformers, installations as well as retrofills.

Implementation Support

It’s one thing to have all the specs, standards and processes but it’s another thing to implement actual installations. That’s why our team is available to answer any question and if you need us, we’ll be on-site to help solve any in-field situation.

Industry Standards

Collectively, our team serves on several committees and standards groups. We’ve proudly spent many years working with industry colleagues to develop standards that enable utilities and their OEM partners to provide safe, reliable transformer systems in their communities. It’s an honor to work in this industry and we feel privileged to be a part of such a dynamic industry.

Government Relations

Staying apprised of the continual barrage of regulations is tough. We monitor legislative activity in order to understand the impact the EPA and other environmental regulations could have on transformer solutions. Programs like FERC retrofill and RUS loans are just a few programs utilities can take advantage of to help make their transformer programs more cost effective.
