Grant ORCA closed‑loop refrigerated circulator is a sustainability‑focused, energy‑efficient recirculating chiller designed to replace wasteful tap‑water cooling in laboratories. Delivering precise, stable cooling from –10 °C to 40 °C, ORCA uses adaptive refrigeration technology to automatically match cooling power to heat load, reducing energy use and heat rejection into the lab. Compact, quiet, and easy to integrate, ORCA is ideal for reaction chemistry, condensers, rotary evaporation, analytical instruments, bioreactors, and fermentation vessels, helping laboratories cut water consumption, lower utility costs, and meet sustainability targets
