With the ability to heat and cool only when needed and at an impressive operating temperature of +37 °C and consuming only 0.038 kWh, the HettCube 400 R offers just the right cooling abilities for superb growth conditions for cell structures with little or no effect on the environment. This technology not only reduces operational costs but saves energy. The HettCube 400 series features the perks of both forced and natural convection, and the fan is thoughtfully located on the exterior to reduce air flow. Heated through radiated heat protects the cells in the HettCube 400 R against desiccation. The unit features a temperature gauge that not only ensures a uniform distribution of heat but stable temperatures all through the unit. Another notable feature of the HettCube 400 R is the novel Ventilation unit, which makes the unit noise efficient, and reducing noise helps medical staff work efficiently and effectively.
