The Octagon® 40 Advance. Takes the guesswork out of egg incubation

  • 48 hen egg (or equivalent) capacity. Adjustable for eggs from 
    quail to goose size without extras
  • Easy to clean
  • 4 whisper quiet fans and computer modelled temperature distribution 
    for optimum hatch rates
  • Automatic turning
  • Double skinned insulated base for low energy consumption 
    and even temperature

Brinsea’s Octagon 20 and 40 incubators have been popular with bird breeders for decades and the latest models provide a combination of performance and value whichever model you choose. 

The Octagon® 40 Advance combines the high performance Octagon® cabinet and egg handling with Brinsea’s Advance digital control system which puts the control of the incubation process firmly in the hands of the user and ensures reliable hatch rates, time after time

In normal mode the display shows the incubation temperature and humidity to very high levels of accuracy. The simple menu allows the user to change incubation settings:

  • Temperature and humidity display (choice of deg.C or deg.F)
  • Temperature and power fail alarms with adjustable sensitivity
  • NEW cooling option
  • Factory calibration
  • Automatic Humidty Control

The Octagon® 40 Advance can be upgraded to EX specification with the addition of the Brinsea® humidity pump to give full automatic control of humidity.
Cabinet.The high quality incubator cabinets are entirely injection moulded from high grade ABS which makes them durable and easy to clean. The base is double skinned and foam filled to reduce heat loss meaning lower electricity consumption and better temperature distribution. The incubator tops are clear allowing good visibility of the eggs and chicks inside. 

Humidity and ventilation. Air is circulated by long life computer fans which, coupled with the unique grilles with optimised air diffusers, means extremely even air temperature throughout the egg chamber. Fresh air is controlled with a vent slider and humidity is provided by water in reservoirs in the base (unless the EX pump is used – Advance models only). 

Egg Handling. Egg turning is achieved by rocking the whole cabinet from side to side either by hand (hence the Octagon® shape) or with the automatic turning cradle which moves the incubator through 90° approximately once each hour. External egg turning keeps the incubator interior free from motors and mechanisms which makes cleaning easier. Autoturn cradles are supplied as standard with all Octagon® 40 models. To accommodate eggs of different sizes the two removable egg trays are supplied with dividers which the user can position to suit their eggs and maximize the number that can be held. Eggs from as small as finches to as large as geese can be incubated. The Octagon® 40s hold up to 48 hens eggs or equivalent.

Periodic Cooling - Cooling is an entirely natural process as most birds will get off the nest at least once a day and leave the eggs unheated for a significant time. Recent research has also shown that hatch rates can actually increase significantly as a result of cooling. For this reason Brinsea® have now incorporated a cooling option in all their Advance models of egg incubators for 2012. This feature turns the incubator’s heater and low temperature alarm off for a selected period but keeps the fan running. After the cooling period is complete the incubator reverts to normal temperature and the alarm is automatically reset.

This incubator has everything.Review by P. Henderson
I was considering both this incubator and the GQF Sportsman digital incubator. I am so glad I chose this one! I really didn't need space for 200+ eggs, and this one has all the features I could ever hope for. I am glad I spent the extra money on this unit instead of a cabinet incubator. It fits on my counter perfectly and is very easy to clean between incubation periods. Overall, I would highly recommend this unit to those who may not be hatching a ton of eggs, but want a lot of control and automation of their hatch. It is worth the money. (Posted on 8/7/2013)
