Freezer Incubator

    Here is my freezer incubator project.
    I am building an incubator of an old freezer and for this cause I used the Liebherr Economy.
    In this incubator is room for 88 eggs max., but a better aircirculation will be achieved by taking a maximum of 66 eggs.
    For me this capacity is more than enough.
    This old freezer didn't work anymore, so I took out all freezer parts and started making an incubator of it.

    I am not so well in English so I will place here some pictures of my project. Pictures say more than words.


    The old freezer All freezer-parts removed

    This was the inside before I took out the parts The original name of the freezer

    I made a window made out of 6mm glass on the inside and outside. There is a 5,5cm space between the glasses for better isolation.

    For security I installed the fan and the heating-source on an aliminium plate.
    I also installed a SSL- light( solid state lighting), because it doesn't cause heat.

    I installed a Thermotronic thermostat I finished-off the inside of the door.

    Testing all the equipment

    This is my new incubator made of an old deep freezer.
    The Thermotronic thermostat, the fan, the heating-source and a hygrometer I have bought at:
    Update May-07-2010

    I have introduced a couple of improvements to this incubator. I have introduced another heating-source and fan.
    Because the heating-source ( 300 watt)was too strong and the engine of the fan, where I have started with, produced too much warmth for this small incubator. The temperature was not well regulable.
    Now I am doing a test with a 60 watt bulb and if my new heating-source of 100 watt has arrived I will change that.
    At this moment the temperature in the incubator is 99.9F and stays very stable.
    I will make a few outcome-drawers where the eggs are able to hatche in.
    The fan I use now came out of an old microwave oven.

    In a couple of days my new heathing-source of 100 watt will arrive and I can also put this into the incubator.
    Then I am almost ready.
    Here are some pictures of the latest improvements.

    I installed the hygrometer I installed fan and heating-source protection.

    I made some egg-turners on which i can place egg-boxes.
    Update May-17-2010

    I made 2 outcome-drawers where the eggs are able to hatche in.

    Outcome-drawers I made some compartments in the outcome-drawers.
    This is my freezer incubator.
    Update August-27-2010

    I will remove the 220 volt Fan that still produced excess heat and place a 12 volt computer case fan. I use this one in combination with an Zalman Fanmate 2 Fancontroller so I can regulate the speed and make it with less noise. For power I use a 12 volt DC adapter 1000MA. Advantage of 12 volts is that it would be safer if properly connected.
    Update March-28- 2011

    I promised to inform you how the breed has gone. I have 54 eggs laid into my freezer incubator to breed up to 18 days. On the 19th day I have 50 fertilized eggs transferred to the still air incubator for the eggs to hatch. Unfortunately, I knocked at the thermostat and the temperature was too high for 2 hours, about 103 Fahrenheit. Unfortunately, some died but I still have 27 beautiful chicks.

    Greetings Arie

    A bit more info on the pic progress would have been good.

    So you can't hatch them in the first incubator? Did you use another diy unit for the hatching bator?

    I love this, because you can pick up a used mini fridge or freezer at goodwill for $10, less than the cost of a freezer

    Yes Michael, it works very well at the moment.
