AG Optimists

Precision Industrial
Temperature Control Solutions

AG Optimists engineers precision cooling and heating systems for demanding industrial operations — from −80°C (−112°F) ultra-low extraction, to freeze protection on the coldest job site, to industrial heating applications up to 200°C (392°F). Two specialized brands, one standard of engineering.

What We Do

Engineering-led temperature control.

We don't sell boxes. We size, spec, and build thermal systems around your process, your fluid, and your conditions.

Application Engineering

Every system is sized to your actual load, fluid, flow, and ambient — not a catalog approximation. Real thermodynamics, verified.

Full Thermal Spectrum

Cooling down to −80°C and heating up to 200°C — a single partner for both ends of your process.

Standard Products in Stock / Custom Solutions Built to Order

Standard lines when they fit, custom builds when they don't. Made-to-order equipment with U.S. based engineering support.

Why AG Optimists

One partner for the entire temperature range.

We provide engineered solutions for both cooling and heating applications, even when a process swings from ultra-low extraction to freeze-protected storage, you deal with one engineering team that understands the whole picture.

That means consistent standards, honest sizing, and equipment matched to what your operation actually runs — backed by people who pick up the phone.

Questions & Answers

The quick answers.

What is AG Optimists?
AG Optimists (AG-Optimists, LLC) is a U.S. industrial temperature-control company that engineers precision cooling and heating systems for demanding industrial processes. It operates two specialized brands: AG Chill for industrial process chillers and AG Heat for industrial heating and freeze protection.
What temperature range does AG Optimists cover?
The full industrial thermal spectrum — from −80°C (−112°F) ultra-low process cooling up to 200°C (392°F) process heat — across its two brands, AG Chill (cooling) and AG Heat (heating).
What is the difference between AG Chill and AG Heat?
AG Chill provides industrial process chillers (cooling) down to −80°C ultra-low — for extraction, pharmaceutical, semiconductor, food, and lab processes. AG Heat provides industrial heating and freeze protection — drum, tote, pail, cylinder, and pipe heating, ground thawing, and process heat up to 200°C. One company, one engineering standard.
What industries does AG Optimists serve?
More than 50 industries across cooling and heating — including pharmaceutical & biotech, botanical extraction, breweries/wineries/distilleries, semiconductors, data centers, food & beverage, chemicals, oil & gas, plastics, aerospace, and metalworking.
Are AG Optimists systems custom-built or off-the-shelf?
Both. Standard product lines are used when they fit, and systems are application-engineered and made to order when they don't — sized to your actual load, fluid, flow, ambient, and operating conditions rather than a catalog approximation.
Where is AG Optimists based, and is support U.S. based?
AG Optimists is U.S. based, with U.S. engineering and responsive support, and equipment made to order. You can reach the team at 801-244-9769 or through either brand's contact form.
