Frequently Asked Questions
What is the temperature range of the WDF-86V340II?
The WDF-86V340II operates from -40°C to -86°C with microprocessor-controlled precision in 1°C increments, displayed on a 7-inch touch screen control panel.
How does the WDF-86V340II save energy?
The WDF-86V340II uses HC (hydrocarbon) refrigerant that achieves 50% energy savings compared to conventional CFC-based ultra-low freezers, combined with VIP insulation panels and optimized door seals.
What is cascade refrigeration in the WDF-86V340II?
Cascade refrigeration uses two refrigeration cycles working in series. The first cycle pre-cools refrigerant for the second cycle, allowing the WDF-86V340II to efficiently reach -86°C while maintaining reliable, balanced operation.
What alarms does the WDF-86V340II have?
The WDF-86V340II includes high/low temperature alarms, power failure alarm, sensor error alarm, clean-filter alarm, extremely high ambient temperature alarm, and remote alarm contacts with audible buzzer and visual flashing light.
What is the storage capacity of the WDF-86V340II?
The WDF-86V340II provides 340 liters of ultra-low temperature storage with four separate insulated compartments and adjustable shelf heights for flexible sample organization.
What voltage range does the WDF-86V340II support?
The WDF-86V340II operates on 220V/50Hz with a wide voltage tolerance of 185V to 260V, and functions in ambient temperatures from 10°C to 32°C.
What can I store in the WDF-86V340II freezer?
The WDF-86V340II is suitable for long-term storage of biological products, vaccines, plasma, tissue samples, enzymes, and other materials requiring ultra-low temperatures in laboratories, hospitals, and research institutes.
How does the WDF-86V340II compare to the WDF-86V340E self-cascade model?
The WDF-86V340II uses a cascade refrigeration system with two compressors for robust cooling performance, while the WDF-86V340E uses self-cascade technology with a single compressor for a simpler design and lower maintenance.
Does the WDF-86V340II have a data logging feature?
Yes, the WDF-86V340II includes a USB port for downloading temperature data records, enabling compliance with storage documentation and regulatory requirements.
What certifications does the WDF-86V340II have?
The WDF-86V340II is certified to ISO 9001, ISO 13485, and ISO 14001, ensuring compliance with international quality, medical device, and environmental management standards.
