Five series, one platform — separated mainly by how cold they take your process fluid. Find the right one below, then size it with the calculator or talk to an engineer.

Specifications are typical and vary by configuration. All series are USA-built and UL/CSA certified (ELT is ETL-listed, ISO 9001:2015). Larger and custom builds available on request.
Pick the coldest fluid temperature your process actually needs, then choose the series that reaches it. Running warmer than a series’ minimum is always fine.
Open the calculator ›Hydrocarbon and ethanol operations condensing solvent or subcooling usually land in the SLT (-58°F) or ULT (-112°F) range.
Extraction guide ›Most industrial process loops, glycol systems, and cultivation cooling are handled by the Standard (40°F) or LT (10°F) series.
Glycol guide ›Odd footprint, unusual fluid, larger capacity, or special power? We engineer to spec.
Request a custom build ›The sizing calculator takes your temperatures and flow and returns the series and tonnage that fit.
