MAQUET HEATER-COOLER UNIT HCU 30
MAQUET · Model HEATER-COOLER UNIT HCU 30
Modern Exterior Design - The HCU 30 has an elegant and easy to clean Polyurethane top cover and a user-friendly full graphic display. It is revolutionary in design and simplicity. Extremely High Cooling Capacity - The HCU 30 offers exceptional cooling capacity through its fast ice building technique and powerful compressor. The ice accumulates an initial cooling effect almost three times as high as the classic heater-cooler systems, resulting in reduced patient cooling times. This method also allows the machine to be operated in most cases without a running compressor, eliminating disturbing noise and draught from the compressor and the fan. Moreover, ice can easily be added for rapid extra cooling in an emergency situation. Effective Heating - The large capacity heater incorporates smooth and precise electronic control. This technique optimizes the efficiency and minimizes patient re-warming time. The automatically controlled mixing valve enables very fast switching from cooling to heating and back to cooling again. Unique Pressure and Flow Control - The machine also features a unique pressure and flow control. The maximum outlet pressure can be set to avoid damaging external devices. The perfusionist has the possibility to adjust the flow directly from the display. Reducing the flow provides a more silent operation. Fast priming and automatic de-airing - Key features include effective fast priming and automatic de-airing. A smart interior design allows air to be dispelled from the external and internal circulation very effectively, resulting in extremely short set-up times and smoothly running pumps. Effective emptying of external circuits - The HCU 30 offers really unique and effective emptying of external circuits. The device regains water by sucking it back from heat exchangers and water supply tubing, saving time and effort. This convenient emptying procedure almost eliminates water spillage, reducing the risk of wet slippery floors. Integrated cleaning technique - The HCU 30 has the most effective integrated cleaning technique available. The fuid and inner water path can be heated up to 90°C, in order to clean the water and prevent the growth of bacteria and other microbes. Remote Control - The HCU 30 can also be controlled by an optional Remote Control Unit.
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.

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 structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Heater / element fault
- Confirm the presentation - typically no heat, overheat alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: element or thermal fuse failure.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the heating element / thermal fuse per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
Symptom: Fan / airflow failure
- Confirm the presentation - typically uneven warming, hotspot - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: blower wear.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the blower fan per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.
