What it is

General reference — not yet source-verified

The Thermo Fisher ThermoFlex 24000 Chiller is a process chiller. Machines of this class are support utilities that provide stable cooling to external equipment by circulating a heat-transfer fluid through a closed loop.

How it works

General reference — not yet source-verified

Machines of this class pump a conditioned fluid through tubing to a connected load and back to the chiller. Heat absorbed at the load is transferred inside the unit to a refrigeration circuit or other heat-rejection stage, after which the fluid is cooled and recirculated.

Such systems typically combine a reservoir or fluid path, pump, heat exchanger, refrigeration components, sensors, and control logic. The controller monitors supply and return conditions and adjusts cooling activity to hold a target temperature within an operating band while also managing flow, pressure, and protective interlocks.

Frequently asked questions

Why is temperature stability important for connected equipment?General reference — not yet source-verified

Stable temperature helps maintain repeatable tool behavior, protects sensitive assemblies from overheating, and reduces drift in processes or measurements that are affected by thermal variation.

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

Typical loads include instruments, laser sources, vacuum and plasma subsystems, power modules, and other assemblies that generate heat or require controlled cooling fluid.

How is heat removed from the circulating fluid?General reference — not yet source-verified

Such systems transfer heat from the returning process fluid into an internal heat exchanger linked to a refrigeration circuit or another heat-rejection method. The cooled fluid is then sent back to the load to repeat the cycle.
