🏠 The foundation on which the entire incubator rests.
The COSMO base is the lower ABS shell that contains the humidity trays, supports the support mesh, and holds up the entire structure. If it cracks or breaks, you lose its watertightness, moisture retention, and stability.
Quick diagnosis: visible cracks, water leaks from the trays, body deformed by heat, breaks at the corners or attachment points.
Solution: Original FIEM COSMO primer in high-strength ABS. Compatible with COSMO, COSMO EVO, and COSMO ML.
📌 Real case: A customer in Vicenza with a COSMO incubator had a cracked bottom after 8 years of use. Water leaked from the trays, and the humidity never rose above 40%. After replacing the bottom, the incubator returned to working perfectly with stable humidity.
⚠️ When to replace it: If you notice cracks, warping, or water leaks, the bottom should be replaced. A damaged shell compromises airtightness and humidity, ruining entire broods.

The COSMO base is the incubator's lower body, made of high-strength ABS plastic. It's the "floor" of the machine: it contains the modular humidification trays, houses the bottom mesh where the eggs rest, and supports the entire upper structure.
The integrated trays allow for natural surface humidification: the water evaporates and maintains the right humidity level inside the incubation chamber. The external filling system makes it easy to top up the water without opening the machine.
The quality of the ABS material is crucial: it can withstand constant heat (37-38°C for weeks), high humidity, and repeated washing with disinfectants. A poor-quality base will warp, crack, and lose its watertightness.
📋 Exploded view reference: This component corresponds to number 5 in the exploded view diagrams of FIEM COSMO incubators. Useful for identification during maintenance.
Replace COSMO primer if you notice:
The bottom gets damaged for three main reasons: natural wear after years of intensive use (7-10 years), prolonged exposure to heat and humidity which weakens the plastic, or accidental knocks and falls during moving or cleaning.
A cracked or warped bottom causes serious problems: water leaks from the trays, humidity levels plummet, and the eggs dry out. People often think it's a humidity or ventilation problem, but simply checking the bottom reveals an invisible crack. A hatch with too low humidity means chicks that fail to crack their shells or are born weak.
