The HettCube 600 uses a low environmental impact for optimum growth conditions of cultures. The incubator heats up when necessary and at 37 degrees C only consumes 0.049 kWh for energy saving. The low impact energy also reduces operating costs and saves money. The HettCube uses natural and forced convection with a fan housed outside of the usable space, reducing air flow. By heating through with radiated heat, the cells are protected against desiccation. Precise temperature control means stable temperatures for uniform distribution of heat. The unique ventilation system means the incubator is runs quietly so users are not exposed to load noise levels when working. The airflow system, along with optimal insulation, uses no inner doors for easy loading and unloading.
