NARWHAL Add for comparison Closed loop refrigerated circulator

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 

Key Features

• Energy efficient, adaptive cooling – cooling power up to 600W adapts to varying heat load conditions across a range of -15 to 40°C
• Easy to use and intuitive interface. No training required
• System exhausts less heat to the room, reducing demand on HVAC
• Effective cooling control with excellent stability of ±0.2°C
• Powerful 1000mbar pump and adjustable flow rate up to 24L/min
• Easy integration - compact design with a range of accessory connectors and hosing kits
• Peace of mind - 3-year warranty and high quality, manufactured in the UK
• Very quiet operation
• New modern, eye-catching design to stand out in labs 
• UK designed and manufactured to the highest specifications 

Applications

• Ideal for reaction chemistry, condensers, reflux, solvent extraction and Soxhlet systems
• Higher power cooling and pumping allows for cooling in series/parallel
• Replaces high‑cost tap‑water cooling with closed‑loop
• Precision for better accuracy and reproducibility
• Cooling for analytical instruments, biological workflows, optics and general temperature control
• Temperature control of bioreactors and fermentation vessels 
• Great for facilities aiming to cut water use and meet sustainability standards such as LEAF
