🔗 The lock that holds the entire incubator together.
The GACOS is the hook with a threaded insert that connects the lower shell to the upper shell. If it breaks or loosens, the two shells will no longer seal properly, and you lose heat and moisture.

Quick diagnosis: shells that do not engage, broken or bent hook, stripped threaded insert, closure that does not hold.

Solution: Original FIEM GACOS for COSMO, COSMO EVO, and COSMO ML incubators. Price each.

📌 Real case: A customer in Treviso with a COSMO EVO had a car that wouldn't close properly and was losing heat. He thought it was an electrical problem, but it was just a broken GACOS. It was replaced in 2 minutes, and the problem was solved for less than 3 euros.

⚠️ When to replace: If the two shells no longer fit securely or you notice any play between the parts, check the GACOS immediately. An imperfect seal disperses heat and moisture.

⚙️ How does GACOS work?

The GACOS is the fastening system that holds together the two halves of the COSMO incubator: the lower body (bottom) and the upper body. It consists of a metal hook and a threaded insert that screw together, creating a secure and stable closure.

A tight seal is essential for maintaining a constant temperature and humidity inside the incubation chamber. If the GACOS are broken, loose, or missing, the two shells won't fit together perfectly, creating invisible gaps that disperse heat.

📋 Exploded view reference: This component corresponds to number 6 in the exploded view diagrams of FIEM COSMO incubators. Useful for identification during maintenance.


🔍 When to replace this part

Replace the GACOS if you notice:

  • ✓ Broken or bent hook: The metal hook has broken or become deformed.
  • ✓ Stripped threaded insert: the thread is worn and no longer holds.
  • ✓ Shells that don't fit together: the two shells no longer fit together securely.
  • ✓ Play between the shells: the two halves move even when they are hooked together.
  • ✓ Heat loss: the temperature fluctuates despite the heating element and thermostat working.

⚠️ Why it happens and what you risk

GACOS are damaged primarily by mechanical wear: opening and closing the incubator hundreds of times over the years stresses the mechanism. Excessive force when closing or accidental impacts can also break them.

A broken GACOS means an imperfect seal. Even a small gap between the two shells causes heat and humidity to escape. Temperature fluctuates, humidity drops, and hatching is affected. People often think it's a problem with the heating element or thermostat, but a few euros for a new GACOS will solve the problem.


✅ Compatibility verified

This hook is specific for FIEM incubators of the COSMO series:


📦 COSMO EVO / EVO Plus
Versions with color LCD control unit


📦 COSMO ML (MiniLed Advanced)
Version with 3-digit digital display

⚠️ Important note: This hook is specific to the COSMO series. It is NOT compatible with SMART, INCA, CIP CIP, or MG which have different locking systems.

🔧 Assembly in 3 simple steps

⏱ Estimated time: 2-5 minutes | 🔧 Tools: Phillips screwdriver (if needed)

  1. Remove damaged GACOS
    Unscrew or unhook the old GACOS from its mounting point. If the insert is stripped, you may need to remove it with pliers.
  2. Enter the new GACOS
    Place the threaded insert into the hole in the body and screw the hook until it locks securely.
  3. Final test
    Close the incubator and check that the two shells fit snugly together without any play. Try opening and closing them several times to make sure the latch holds securely.

🛡️ How to make them last longer

  • ✓ Every 6 months: check that the hooks are tight and that there is no play.
  • ✓ During use: close the incubator gently, without forcing the hooks.
  • ⚠️ DON'T: never force the door to close if the frames are not aligned, do not hang weights on the hooks.

Perforated Bottom Grid for Fiem Smart / Plasti...

€11.80
Availability: 999 In Stock

🥚 The Smart net is not a simple shelf: it is the perforated technical floor that supports the eggs allowing perfect circulation of air and humidity from below!

At €9.70 (excluding VAT) , the SMART PL. NET (component no. 11 in the exploded view) is the support grid where you place your eggs. Its perforated structure is not random: it allows warm air to circulate evenly from bottom to top and the humidity from the four sectors below to evaporate, reaching the eggs, creating the perfect microclimate essential for embryonic development.

💨 As the FIEM manual specifies, air circulation is as crucial as temperature. Hot air rises through the mesh, enveloping each egg evenly, while the moisture evaporating from the trays at the base passes through the grill, maintaining the proper 47-62% ratio needed for the various stages.

⚠️ When should you replace it? If the mesh is broken or warped, compromising the egg holder, if the plastic is bent, creating unevenness, if it's clogged with debris blocking airflow, or after several cycles, when thorough cleaning is required.

💡 The mesh size is designed to hold eggs of various sizes (from quail to goose), always ensuring optimal airflow and humidity. Without this perforated grid, you wouldn't have the necessary ventilation!

✅ Compatible exclusively with the Smart model . Specific dimensions and design to fit perfectly into the structure.

Fiem Smart Adhesive Keyboard Membrane /...

€3.40
Availability: 1000 In Stock

⌨️ The keyboard membrane is not just a sticker: it is the interface between you and the electronic brain of your incubator, allowing you to precisely control temperature and humidity!

At just €2.80 (excluding VAT) , the MEMB.TAST.DIG membrane is the touch control panel for the Smart digital thermostat. This thin film with printed buttons is what allows you to set the vital parameters: temperature at 100°F, humidity at 47-62%, and sensor calibration.

🎯 As specified in the FIEM manual, pressing the SET buttons accesses the reference values, and using the up/down arrow keys changes the temperature and humidity. Without a functioning membrane, you cannot control the digital incubator!

⚠️ When should you replace it? If the keys no longer respond to pressure, if the surface is worn and the symbols are no longer legible, if it has cuts or tears, if the adhesive has peeled off the panel, or if liquids have penetrated the contacts.

💡 A common problem: after years of use, the membrane loses sensitivity. Press SET but nothing happens. Before you think the entire thermostat is broken, often all you need to do is replace this inexpensive membrane!

✅ Compatible only with Smart Digital Thermostats . Make sure you have the model with a 3-digit digital display.

📱 Is your thermostat no longer responding? Send us photos of the control panel on WhatsApp and we'll confirm if the membrane is sufficient.

🚚 Ships from Como in 1 day. Minimum order €20 - add thermometer, clips, or other useful spare parts. FIEM since 1975 , Padovan Avicoltura always has membranes and digital components in stock. 24-month warranty for private individuals, 12 VAT numbers.
