Frequently Asked Questions
What is the temperature range of the WDF-86V188E?
The WDF-86V188E operates from -40°C to -86°C with microprocessor control adjustable in 1°C increments via a digital touch screen display.
What is self-cascade technology in the WDF-86V188E?
Self-cascade technology uses a single compressor with a special refrigerant mixture to achieve -86°C. This eliminates the need for two compressors, resulting in a simpler, more reliable design with fewer mechanical components.
How much can the WDF-86V188E store?
The WDF-86V188E provides 188 liters of ultra-low temperature storage, making it the most compact model in the self-cascade series, ideal for smaller laboratories with limited floor space.
What alarms does the WDF-86V188E include?
The WDF-86V188E features high/low temperature alarms, power failure alarm, sensor error alarm, and audible and visual alerts with a USB data port for temperature logging.
What are the advantages of a single compressor in the WDF-86V188E?
The single compressor self-cascade design means fewer moving parts, lower maintenance requirements, reduced noise levels, better energy efficiency, and a more compact footprint compared to dual compressor systems.
Is the WDF-86V188E suitable for small laboratories?
Yes, the WDF-86V188E is specifically designed for smaller laboratory settings with its compact footprint, 188L capacity, and wide voltage compatibility, while still achieving the full -40°C to -86°C temperature range.
How does the WDF-86V188E compare to the WDF-86V340E?
The WDF-86V188E offers 188L in a compact footprint while the WDF-86V340E provides 340L. Both use the same self-cascade single compressor technology and -40°C to -86°C range. Choose based on your storage volume needs.
What can I store in the WDF-86V188E?
The WDF-86V188E is suitable for storing biological products, vaccines, enzymes, tissue samples, and other materials requiring ultra-low temperatures in research labs, clinics, and smaller healthcare facilities.
Does the WDF-86V188E have data logging?
Yes, the WDF-86V188E includes a USB data port for downloading temperature records, enabling compliance with storage documentation and regulatory audit requirements.
What certifications does the WDF-86V188E have?
The WDF-86V188E holds ISO 9001, ISO 13485, and ISO 14001 certifications, meeting international standards for quality management, medical devices, and environmental management.
