For the compressor-based NG-ISCC models, routine maintenance is mainly preventive housekeeping that keeps cooling performance stable and helps you hold repeatable specimen conditioning temperatures. In day-to-day use, focus on cleanliness, airflow, and regular checks of the cooling medium and seals.

Because these chambers use a non-freezing liquid medium such as ethanol, good practice is to keep the fluid clean, at the correct level for your workload, and free of moisture or debris. Labs also typically perform periodic temperature verification checks to support consistent Charpy specimen soak conditions before transfer to the impact tester.

Common routine checks include:

• Wipe down the interior and remove residue after spills.
• Inspect the door or lid seal for damage, frost buildup, or poor closure.
• Check the cooling medium condition and top up or replace as needed.
• Keep the condenser air path clear, clean dust from intake areas, and maintain clearance around the unit.
• Confirm controller stability and sensor readings with your lab’s verification routine.
