What it is

The Neslab HX 750 W has a temperature range of +5 to +35 degrees Celsius.[1][2]

How it works

General reference — not yet source-verified

A recirculating water chiller works by continuously circulating a coolant through a closed loop, removing heat from a connected process tool and rejecting it through a refrigeration cycle.

Where it fits in the process flow

General reference — not yet source-verified

The chiller connects to a specific tool's cooling water inlet and outlet, maintaining a constant temperature setpoint to prevent thermal drift in sensitive processes such as lithography, etching, or metrology.

Frequently asked questions

Why use a closed-loop chiller instead of utility water alone?General reference — not yet source-verified

Machines of this class provide cleaner, more stable, and more controllable cooling conditions than an uncontrolled utility supply at the tool connection. A closed loop also helps reduce contamination exposure, limit fluid consumption at the point of use, and isolate the supported equipment from variation in facility water temperature.

What kinds of equipment are commonly connected to this class of system?General reference — not yet source-verified

Typical connected loads include lasers, analytical instruments, vacuum pumps, power supplies, condensers, imaging systems, and process hardware with water-cooled jackets or heat exchangers. Any tool that generates heat and requires stable coolant temperature may use this class of support equipment.

What are the main functional elements of a recirculating chiller?General reference — not yet source-verified

Machines of this class generally include a pump to move fluid, a refrigeration section to remove heat, a heat exchanger, fluid containment, sensing and control hardware, and protective alarms or interlocks. Together these elements create a self-contained thermal control loop for external equipment.
