Sorin Group 3T Heater-Cooler System
Sorin Group · Model 3T Heater-Cooler System
Extremely short pre-cooling times due to the small volume of the tank Separate tanks enable switching between warm and cold cardioplegia without delay Cooling with the ice container is not necessary during routine operation due to the strong performance of the compressor assembly An independent safety system prevents the water temperature from reaching critical values The two-chamber pumps minimize any pressure inside the heat exchanger The suction stage of the pumps enables a smooth emptying of the heat exchanger and the tubing.
Key tips
- ·Never skip temperature-accuracy verification to save time - it's the one check that directly prevents burns.
- ·Hose/blanket connector wear is the most common real fault and the easiest to miss on a quick visual check.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Will not reach or hold set patient / water temperature
HighSymptoms: Water temperature drifts from setpoint, patient temperature not tracking, over/under-temp alarm.
Root cause: Heater / thermoelectric or refrigeration fault, a temperature-probe fault, or a circulation-pump / flow fault.
Circulation-pump / flow fault
MediumSymptoms: Low-flow alarm, blanket not filling, pump noisy.
Root cause: Worn pump, an air-locked circuit, or a kinked / disconnected hose.
Patient-probe fault
MediumSymptoms: Patient temperature implausible or open-probe alarm, auto-control will not regulate.
Root cause: Damaged patient temperature probe or its connector.
Leak / reservoir fault
MediumSymptoms: Low-water alarm, water on the floor, air in the lines.
Root cause: Reservoir low, a hose / fitting leak, or a blanket leak.
Refrigeration fault (cooling units)
MediumSymptoms: Cannot cool water, compressor not running.
Root cause: Compressor, condenser fan, or a sealed-system fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Hose / blanket connector inspection
- ·Temperature-accuracy verification
- ·Annual electrical safety test
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Will not hold set temperature
- Confirm the reservoir is filled and the blanket circuit is primed (no air).
- Verify the water temperature against an independent thermometer.
- Check the patient probe against a reference and swap it.
- Confirm the circulation pump delivers flow.
- Replace the probe, pump or heater / refrigeration components as isolated.
Symptom: Low-flow or leak alarm
- Check the hoses for kinks and confirm the quick-connectors are seated.
- Top up the reservoir and bleed air from the circuit.
- Inspect the blanket and hoses for leaks.
- Replace a leaking hose / blanket.
- Confirm the flow alarm clears and temperature control is stable.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Plastic heat exchanger fibers separating the blood compartment from the water compartment in certain oxygenators may allow diffusion of hydrogen peroxide in a quantity that exceeds allowable limits.
- RECALL
Potential colonization of organisms, including Mycobacteria, in Sorin Heater Cooler Devices, if proper disinfection and maintenance is not performed per Instructions for Use.
- RECALL
On August 15, 2012, Sorin informed consignees via letter of changes made to create Version 12 of the Heater-Cooler 3T IFU. The revised IFU included enhancements to achieve water quality that meets the standard for German drinking water.
