Ultra deep freezer 408 l -40℃～-86℃

**Security**

Fault alarms including high and low temperature, power failure, sensor failure, filter cleaning required, extremely high ambient temperature, abnormal voltage, thermostat failure, low battery level, capacitor cleaning required, open door.
Visual and acoustic alarms.
Door opening function and USB port for downloading temperature data are standard on stationary models.
Remote alarm contacts.

**Energy saving**

Unique door seal design for minimum loss of cold temperature during door opening.
High efficiency insulating panels to minimize cabinet heat gain and improve temperature stability.
HC refrigerant for improved efficiency and lower energy consumption.

** Main features**

Microprocessor-controlled system designed for a temperature range of -40°C to -86°C in 1°C increments in the cabinet compartment.
Depending on load requirements and environmental conditions, one or both cooling systems operate on demand, ensuring that samples are fully protected even in the worst conditions.
Optional temperature clamp, storage racks and box.

**Installation and application**

Wide operating voltage range from 187V to 242V, allowing installation in low voltage areas.
Suitable for ambient temperatures from 10°C to 32°C.

**CO2 and LN2 backup system**

Independent CO2 back-up system, LN2 back-up system for ultra low temperature freezers in case of failure and power failure.
The standby refrigeration system consists of a control system and a supply connection system.
The opening and closing of the solenoid valve is controlled by its own temperature sensor. The liquid nitrogen tank or the liquid carbon dioxide tank, as a reserve, is connected via a solenoid valve.

The solenoid valve is powered by an internal rechargeable battery.
