🔌 The caps that close the internal holes and maintain insulation.
COSMO internal plugs are small plastic inserts that seal the fixing holes and openings in the bottom shell. They prevent heat and humidity loss, maintaining a stable incubation environment.
Quick diagnosis: missing, broken, or loose caps, open holes in the body, cold air drafts from below.
Solution: Original FIEM internal caps for the lower body of COSMO, COSMO EVO and COSMO ML incubators.
📌 Real case: A customer from Rovigo noticed unstable temperatures in his COSMO EVO. After checking the control unit and heating element, he discovered that two caps on the bottom were missing. He replaced them and the problem was immediately solved.
⚠️ When to replace them: If the caps are missing or broken, cold air enters from the bottom and hot air escapes. These may seem like small details, but they make a difference in thermal stability.

The internal plugs are small plastic inserts that cover the holes in the bottom casing of the COSMO incubator. These holes are used for fastening during production or to house components, but must remain closed during use.
Their function is simple but important: to prevent cold air from entering from below and warm air from escaping. The COSMO incubator is designed to maintain a hermetically controlled environment, where temperature and humidity must remain constant for 21 days. Every open hole is a potential leak.
The original FIEM caps are made of heat and humidity resistant plastic, with calibrated dimensions to fit perfectly into the holes of the COSMO body.
📋 Exploded view reference: This component corresponds to number 11 in the exploded view diagrams of FIEM COSMO incubators. Useful for identification during maintenance.
Replace the COSMO internal caps if you notice:
The caps are mostly lost during cleaning or when the incubator is disassembled for maintenance. They can also break if you force them out or if the plastic has hardened over time.
A missing cap may seem like a minor detail, but it can cause real problems: cold air entering from the bottom creates a cold zone that the heating element must compensate for, increasing fuel consumption and creating thermal instability. People often think the problem is the control unit or the sensor, when simply inspecting the caps can identify the cause.
