Double Cooling Series
The HAIER ultra-low freezer of the double cooling series guarantees maximum performance and safety thanks to its TWIN-Power technology. Our freezers offer the best protection by using a redundant compressor system with two independent cooling circuits. At the same time, the innovative IQ-cool.tec technology with its intelligent cooling system ensures low energy consumption.
The HAIER freezers offer users the highest protection for valuable samples. Our redundant compressor system ensures constant cooling. If one compressor should fail unexpectedly, the second one maintains the cooling circuit and ensures cooling at -80°C.
- TWIN power for maximum performance and safety
- Energy-efficient thanks to IQ-cool.tec
- Multiple door seals with VIP+ Hybrid insulation reduce cold air loss in compartments. There is little effect on compartment temperatures when a compartment is opened in normal operation.
- Fast reopening of doors through vacuum release
- User-friendly touch display
- Highly efficient and highly reliable cooling fans allow energy savings and safety during long-term storage (by means of temperature control at the compressors).
- Multiple alarm functions including over-temperature alarm, under-temperature alarm, sensor fault, battery discharge, high ambient temperature, power failure, etc. ensure product and equipment safety.
- Best recovery time on the market
- Casing made of painted sheet steel
- 20 years guaranty on the VIP+ isolation
- 6 years guaranty on the compressor (connected with a maintenance contract)
- The temperature inside the cooling chamber can reach up to -86°C with uniformity within 5°C
- Wide range of operational voltage from 200V to 260V which allows operating the units even in areas of poor electric supply
Temperature / Cooling system
- Microprocessor control system, control range from -40°C to -86°C in increments of 1°C
- Deep freeze system designed and manufactured under best known practice with components of highest possible quality
Ventilation technique by EBM Papst
- Reliability test carried out and passed on all models, including ageing test of the control electronics at 85°C and 85% relative humidity
- Special design of the control system for a well balanced cascade cooling system
- UL and CE certified for safety in use
- USB interface for downloading temperature data
- Safety padlock at the outer door
- Operable at ambient temperature from 10°C to 32°C
- Input voltage and ambient temperature are displayed simultaneously to ease supervision of ambient conditions
- Lockable door handle and/or individual key to avoid that other people, also having a deep freezer, can have access to your valuable samples. Furthermore there is space for an additional padlock for extra safety.
- CO2 safety system including control, alarm backup and CO2 valve
