NARWHAL Recirculating Chiller

Energy‑efficient recirculating chiller, helping labs cut water use, lower utility costs and meet sustainability targets

Grant NARWHAL 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 –15 °C to 40 °C, NARWHAL 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, NARWHAL 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
