🔗 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.

Fiem Smart 130-B Gear Motor Cover | Egg Turner Protection
FIEM

Fiem Smart Gearmotor Protection Cover / Plastic...

€6.54
Availability: 1000 In Stock

🛡️ The gearmotor cover isn't just an aesthetic protection: it's the shield that protects the heart of the egg turning system from dust, humidity, and accidental tampering!

At just €5.36 (excluding VAT) , the 130-B cover protects the Smart's egg turning gear motor from external elements that could compromise its operation. It's more than just decorative plastic: it keeps the motor compartment isolated from the incubator's constant humidity, prevents dust from accumulating on the gears, and protects against accidental contact during operation.

🔒 As specified in the FIEM manual, the gearmotor is housed in an insulated compartment protected by this very cover. Without it, humidity from incubation penetrates the mechanism, dust accumulates, and the motor wears prematurely.

⚠️ When should you replace it? If it's cracked or broken, if it no longer seals the compartment tightly, if the plastic is warped and leaves cracks, if the attachment points are broken, or if it's missing after maintenance on the gearmotor.

💡 A missing or damaged cover exposes the expensive gearmotor (€44) to premature wear. For €5.36, you're protecting a much greater investment!

✅ Specific for Smart , designed to perfectly close the gearmotor compartment.

📱 Is the lid not closing properly? Send us a WhatsApp photo of the compartment and lid.

Digital thermostat T/H Fiem Smart Incubator
FIEM

Fiem Smart Precision Digital Thermostat T/H /...

€69.54
Availability: 1000 In Stock

🌡️ The digital thermostat is not a simple regulator: it is the electronic brain that maintains temperature and humidity with surgical precision, determining the life or death of your embryos!

At €57.00 (excluding VAT) , the DIG.SMART (part no. 7 in the exploded view) is the intelligent heart of your incubator. With a 3-digit digital display, it controls both temperature and humidity (T/H) with precision to the nearest tenth of a degree. It's not comparable to old analog thermostats: this is precise digital control that maintains a vital 37.7°C without lethal fluctuations.

🎯 As specified in the FIEM manual, pressing SET accesses the reference values, and using the up/down arrows adjusts the temperature (100°F) and humidity (47-62%). The display alternates between current temperature, humidity, and setpoint. This digital precision is the difference between hobbyists and professionals!

⚠️ When should you replace it? If the display doesn't light up or flashes, if the temperature fluctuates excessively, if it doesn't maintain setpoints, if the buttons don't respond (try the MEMB.TAST.DIG membrane first), or after years of technological upgrades.

💡 An inaccurate thermostat causes fatal temperature changes: at 36°C, embryos slow down; at 39°C, they die. Digital thermostats maintain accuracy of ±0.1°C!

✅ Specific for Smart , digital version with integrated T/H control.

📱 Temperature issues? Send WhatsApp photos of the display and readings.

🚚 Ships from Como in 1 day. No minimum order. FIEM since 1975 , digital precision for professional results. 24-month warranty for private individuals, 12 VAT numbers.

Fiem Smart Transparent Lid (Exploded View 14)

Fiem Smart Transparent Lid (Exploded View 14)

€37.20
Availability: 999 In Stock

🔝 The clear lid isn't just a window onto your eggs: it's the thermal barrier that keeps temperature and humidity stable, determining the success of your hatchings!

At €30.50 (excluding VAT) , the Smart Lid (part #14 in the exploded view) is much more than just a clear plastic cover. It's designed to create the perfect climate chamber that maintains a constant 37.7°C and the necessary humidity, while allowing you to observe development without constantly opening the lid.

🌡️ The transparency of the material is no accident: it allows you to visually check the thermometer and eggs without losing heat. Any unnecessary opening can cause fluctuations of 2-3°C, which slows embryonic development, which is why an intact and well-sealed lid is essential.

⚠️ When should you replace it? If it has cracks or breaks, even small ones, that cause heat and moisture leaks. If the plastic is cloudy from years of use and you can't see clearly inside. If it no longer seals tightly, leaving gaps. If it has been deformed by excessive heat or impacts.

🔧 As the manual indicates, during the last two days of hatching, the lid must be kept tightly closed to maintain humidity at 62%. It's tempting to open the lid to watch the chicks hatch, but each opening compromises subsequent hatchings!

✅ Compatible exclusively with the Smart model . The specific design with the correct curvature ensures optimal air circulation studied by FIEM.

📱 Not sure about the condition of your lid? Send us photos of the complete incubator and lid from various angles on WhatsApp .

🚚 Protected shipping from Como in 1 business day. Reinforced packaging to prevent breakage. FIEM since 1975 , Padovan Avicoltura guarantees original spare parts. 24-month warranty for private individuals, 12 VAT numbers.
