Two primary heating methodologies dominate CO2 incubator design: water-jacketed and air-jacketed (direct heat) systems, each with distinct advantages. Water-Jacketed Incubators feature an inner chamber surrounded by a jacket of heated water. The water acts as a massive thermal buffer, providing exceptional temperature stability and uniformity. It is highly resistant to ambient temperature fluctuations; if power is lost, the water slowly releases heat, protecting cultures for many hours. However, they are very heavy, slow to heat up initially or recover from door openings, and require a distilled water supply to fill the jacket.

There is also a risk of algae or biofilm growth in the jacket if not properly maintained. Air-Jacketed Incubators use direct, forced-air heating elements and sophisticated fans to circulate warm air. They are lighter, heat up faster, and recover from disturbances more quickly. They offer greater flexibility in chamber size and are easier to move. Their primary challenge is maintaining perfect uniformity, which is addressed through advanced airflow design and control algorithms. The choice often boils down to priority: ultimate stability and power-outage protection (water jacket) versus faster response, lighter weight, and easier handling (air jacket). Many modern air-jacketed models, with excellent engineering, now rival the uniformity of water-jacketed units.
