ChotuKool is a portable, is a CFC-free, fan-cooled thermoelectric cooling system with the following dimensions (wxdxh) 736 x 431 x 383 mm and weighing 7.8kg. It has a capacity of 35L and uses high-end insulation to stay cool without power. ChotuKool doesn't use a compressor, instead it runs on a cooling chip and a fan similar to those used in computers. It operates on 110–240V AC as the main supply. To cope with the erratic power supply in many parts of India (e.g. voltage fluctuation, frequent power cuts, or occasionally a complete lack of electrification in some remote areas), it is equipped to operate on battery or an inverter (Godrej, 2012). The system cools up to a maximum of 28°C lower than the ambient temperature but no lower than 10°C. ChotuKool cuts of the electricity and enters the sleep mode once the temperature of 10°C is achieved. ChotuKool can retain cooling up to 3 hours without electricity with lid closed.

Manufacturer Specified Performance Parameters
ChotuKool consumes half the energy used by regular refrigerators and uses no compressor or refrigerant. It is suitable for cooling food and beverages, and keeping vegetables, fruits, dairy, and so on, fresh. The system cools up to a maximum of 28°C lower than the ambient temperature but no lower than 10°C. ChotuKool cuts of the electricity and enters the sleep mode once the temperature of 10°C is achieved. ChotuKool can retain cooling up to 3 hours without electricity with lid closed.
Vetted Performance Status
As ChotuKool comprises of many recyclable materials, it is advised to consult authorised service providers or Godrej authorised dealers before disposing ChotuKool or its parts. Place the packaging material in the appropriate recycling waste bins, wherever possible. other safety instructions include but are not limited to : ensuring that the air intake area is open and not covered A connection cable provided should be used to connect with the power supply of 110–240V AC.
