Frequently Asked Questions
What is the capacity of the WDF-86V838D ultra-low freezer?
The WDF-86V838D offers 838 liters of storage, making it the largest model in the dual system series. It features four insulated compartments for organized storage of biological samples.
What temperature range does the WDF-86V838D maintain?
The WDF-86V838D maintains temperatures from -40°C to -86°C, controlled via a 7-inch LCD touch screen with 1°C increment precision.
Why choose the WDF-86V838D dual system over a single compressor model?
The dual compressor system provides failsafe redundancy. If one system fails, the other maintains -70°C automatically, offering critical protection for high-value biological samples that cannot afford temperature excursions.
What safety features does the WDF-86V838D include?
The WDF-86V838D includes high/low temperature alarms, power failure alarm with battery backup, door ajar alarm, low battery alarm, sensor failure alarm, remote alarm contacts, and both audible and visual alert systems.
What power supply does the WDF-86V838D require?
The WDF-86V838D operates on 220V/50Hz with a wide voltage tolerance of 185V to 260V, suitable for environments with varying power quality. It functions in ambient temperatures from 10°C to 32°C.
Is the WDF-86V838D suitable for large research facilities?
Yes, the WDF-86V838D is specifically designed for hospitals, blood banks, and large research facilities that need high-capacity ultra-low storage with maximum reliability from the dual compressor system.
How does the WDF-86V838D compare to the WDF-86V838 cascade model?
Both offer 838L capacity and -40°C to -86°C range. The WDF-86V838D dual system provides compressor redundancy for critical applications, while the WDF-86V838 cascade model uses HC refrigerant for 50% energy savings.
Can I monitor temperature data on the WDF-86V838D?
Yes, the WDF-86V838D features a USB port for downloading temperature logs. The 7-inch LCD touch screen provides real-time temperature monitoring with an intuitive interface.
What certifications does the WDF-86V838D hold?
The WDF-86V838D is certified to ISO 9001, ISO 13485, and ISO 14001, meeting international standards for quality management, medical device manufacturing, and environmental management.
How does the WDF-86V838D reduce energy consumption?
The WDF-86V838D uses high-performance VIP insulation panels, a unique door seal design for minimum cold loss during opening, and CFC-free HC refrigerant to optimize energy efficiency while maintaining ultra-low temperatures.
