Brinsea Octagon Incubators

Octagon ECO 20 & Octagon 40

Octagon 20 ECO with autoturn cradle

The Octagon 20 Eco incubator is a simple but high quality egg incubator using the same tough and insulted cabinet as the Octagon 20 Advance coupled to a simple proven electronic temperature control to give reliable hatching results of a wide range of species with minimum fuss.Supplied with the optional autoturn cradle (see below).

Control system

The Octagon 20 Eco controls temperature with high accuracy with a proven proportional band electronic controller with easy tamper-proof adjustment. A flashing indicator shows that the incubation temperature is controlling steadily and temperature is monitored with a conventional but accurate liquid in glass thermometer.


The high quality incubator cabinet is entirely injection moulded from high grade ABS which makes it tough and easy to clean. The base is double skinned and foam filled to reduce heat loss leading to lower electricity consumption and better temperature distribution. The top of the incubator is clear allowing good visibility of the eggs and chicks.

Humidity and ventilation.

Air is circulated by a long life computer grade fan which, coupled with the unique grill with optimised air diffuser leads to extremely even air temperature throughout the egg chamber. Fresh air is controlled with a vent slider and humidity is provided by water in two reservoirs in the base.

Egg Handling

To accommodate eggs of different sizes the Octagon 20 Eco's removable egg tray is supplied with dividers which the user can position to suit their eggs and so maximise the number of eggs that can be held. Eggs from as small as finches to as large as geese can be incubated and a guide to the numbers of a range of popular species which will fit is give in the specification table. Eggs are turned during incubation as the whole incubator is rocked from side to side ? hence the Octagonal cabinet ends. This can be done manually at least twice each day or this turning is performed automatically if the incubator is supplied with the optional Autoturn Cradle which turns the eggs hourly.
