The ThermoFlex900 is a Thermo Fisher recirculating chiller. The ThermoFlex900 uses the ThermoFlex recirculating chillers (Basic Controller) product line. The ThermoFlex900 is designed to provide a continuous supply of fluid at a constant temperature and volume.[1][2][3][4]

What it is
General reference — not yet source-verifiedRecirculating chillers are fluid temperature control systems that supply a continuous stream of coolant at a set temperature to external process equipment. The ThermoFlex900 is a model in the ThermoFlex line of recirculating chillers manufactured by Thermo Fisher Scientific.
How it works
General reference — not yet source-verifiedA recirculating chiller operates by means of a vapor-compression refrigeration cycle. A compressr compresses refrigernt gas, which then condenses in a condensr, relieasing heat. The liquid refrigernt expands through an expansion valve, cooling the evaporator coil. The evaporator absorbs heat from the process fluid as it circulates through the chiller's reservoir and heat exchanger. A pump forces the chilled fluid through an external loop to the process tool and back to the reservoir. The chiller continuously monitors the fluid temperature via a temperature sensor and modulates the refrigeration system to maintain the setpoint.
Why won't it start?
Documented failure modes, common issues, and field considerations.
- The manual states that filling above the MAX LEVEL fill line causes an overflow error (O FLO) and shuts the unit down.
- The manual states that using a fluid not listed in Table 1 voids the manufacturer’s warranty.
