Chest freezer Q-Cell ZNS series

laboratorylow-temperature

Q-Cell series laboratory freezers are divided into two series – Q-Cell ZN standalone freezers and Q-Cell ZNS chest-type freezers. The standalone models offer capacity range of 80-1400 litres. Models up to 300 litres capacity have plastic interior with drawers placed on shelves (the shelves being a part of the cooling system evaporator), and have natural air circulation. Models with capacity from 300 litres up have aluminium (Basic version) or stainless steel (INOX version) interior and forced air circulation. Chest models, due to their construction, guarantee minimized temperature changes caused by opening of the device. The interiors made of aluminium or stainless steel offer capacity within range of 200-600 litres and natural air circulation. Operating temperature range is 0°C to -25°C in standalone models and 0°C to -20°C in chest-type models. Q-Cell 200ZN is the one exception with temperature range all the way to -40°C. Control Our freezers use the driver of the same functionality as that used in refrigerators and incubators (see description on previous pages). Protection Q-Cell Freezers both ZN and ZNS are equipped with alarms indicating a power failure, opening the door of the chamber and temperature sensor failure. Alarm indicating set temperature variation is optional.
