🔗 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.

Semi-automatic humidifier for Fiem Smart incubators
FIEM

Semi-automatic humidifier for Fiem Smart...

€32.33
Availability: 998 In Stock

💧 The semi-automatic humidification kit is an intelligent system that regulates humidity by rotating a bottle, without ever opening the incubator!

At €26.50 (excluding VAT) , the KIT.UM.SMART (component no. 15 in the exploded view) revolutionizes humidity management. It includes a bottle tank, support base, and connection tube, but the genius lies in the control: by screwing the tank, you progressively activate 1-2-3-4 water sectors in the Smart base, unscrewing them to reduce them to 4-3-2-1. Adjust the humidity from 38% to 62% simply by rotating an external bottle!

🎯 How does it work? The variable surface system is ingenious: screw in to increase the flooded sectors (more evaporation = more humidity), unscrew to reduce them. No openings, no temperature changes, total control! During incubation, you need 2 sectors (47-52%), for hatching you activate 4 (62%). Everything from the outside!

⚠️ When should you replace it? If the tank leaks, the sector adjustment mechanism no longer works, the hose is clogged, or if you want to add this intelligent automation to your Smart (only on compatible models).

💡 Revolutionary FIEM system: instead of opening the door twice a day, causing 2-3°C swings, you can adjust everything from the outside. Absolute professionalism!

✅ Compatible with Smart equipped with a 4-sector base (n°4) and pre-arranged lid (n°14).

Perforated Bottom Grid for Fiem Smart / Plasti Flor
FIEM

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.

2.06m - 95W Silicone Heating Cable for Fiem Cip Cip 28 and 40 Incubators
FIEM

2.06m - 95W Silicone Heating Cable for Fiem Cip...

€14.86
Availability: 193 In Stock
R75E Silicone Heating Element for CIP CIP 28 / CIP CIP 40 – The thermal heart of your incubator. This 2.06 meter silicone heating cable ensures even heat distribution throughout the incubation chamber, maintaining a stable temperature essential for embryonic development.

A customer from Padua called me on the 10th day of incubation: the temperature was constantly fluctuating between 36°C and 36.2°C. After checking, the heating element had lost electrical continuity in one spot. I urgently replaced it with the original FIEM R75E, the temperature stabilized immediately, and the eggs hatched successfully.

When is it needed? If your incubator never reaches the set temperature , or takes too long to heat up, or if the thermostat is always on but the heat doesn't increase, the heating element is probably faulty. Abnormal temperature fluctuations can also indicate a damaged heating element.

⚠️ Before ordering: Unplug the power cord, disconnect the resistor, and measure the electrical resistance with a tester : it should read approximately 505 Ohms (2.06 m × 245 Ohms/m). If it reads "infinity" or significantly different values, the resistor is broken. Also check that there are no cuts, burns, or blackened spots on the wire.

📸 Don't have a tester? Send us a photo of the installed resistor on WhatsApp and describe the incubator's behavior: we'll help you diagnose it before purchasing.

Installation: Electrical work that requires care. Always unplug the appliance and, if you are unfamiliar with electrical connections, consult a qualified technician.

💰 Price: €12.18 (VAT excluded, shipping excluded) – FIEM WAREHOUSE COMO

Compatibility: Both the CIP CIP 28 and CIP CIP 40 models use the same R75E resistor.

Minimum order €20: Add other useful spare parts (fuse, fixing collars, thermometer) to complete the order.

📦 Logistics: Ships in 1 business day, delivery 2-4 days. Warranty: 24 months for private individuals / 12 months for VAT numbers.

Temperature Probe for Old Fiem LCD Control Unit

Temperature Probe for Old Fiem LCD Control Unit

€16.72
Availability: 995 In Stock
LCD Thermostat Temperature Sensor (old) – The sensor that detects the incubator's internal temperature and allows the LCD thermostat to regulate the heating. This critical component constantly transmits temperature data to the thermostat to maintain the incubator at 37.5-37.7°C.

When is it needed? If the LCD control unit displays an incorrect or fixed temperature , or the internal temperature fluctuates too much . Even if you see "Err" or "---" on the display, or if the heating element remains always on or always off, ignoring the actual temperature.

Symptoms of a faulty probe: Displayed temperature stuck on one value, impossible readings, resistor that never turns on or off, sudden temperature fluctuations.

💰 Price: €13.70 each (excluding VAT, excluding transport) – FIEM WAREHOUSE COMO – Only original FIEM components from Padovan Avicoltura for guaranteed efficiency over time.

⚠️ OLD Version: This probe is for older models with LCD control units. Newer models with MiniLED Advanced or other modern control units use different probes (T/H PROBE).

Compatibility: MG Series (older LCD models) and CIP CIP (older LCD models). Please check that your incubator has the old LCD control unit before ordering.

Minimum order €20: Consider ordering at least 14 probes (€20.58) as a backup for future replacements, or supplement with other spares (fuse, thermometer, trays).

📦 Logistics: Dispatch within 1 business day, delivery within 2-4 days. Warranty: 24 months for private individuals / 12 months for VAT number. FIEM since 1975.
