  FAQs

  1. What is the temperature range of the -40°C Deep Freezer series?

  The internal temperature is adjustable between -20°C and -40°C via a microcomputer control system.

  2. What industries are these freezers designed for?

  They are designed for medical, scientific research, chemical labs, hospitals, and blood stations to store biological materials and vaccines.

  3. Does the freezer use eco-friendly refrigerants?

  Yes, the units use green, environment-friendly fluoride-free or hydrocarbon refrigerants.

  4. What types of safety alarms are included?

  The systems include high/low temperature alarms, sensor failure alarms, power failure alarms, and door ajar alerts.

  5. How does the insulation technology work?

  The freezers use super-microcellular foaming technology and thick insulation layers (up to 100mm) to maintain stable temperatures.

  6. Can the temperature be monitored during a power failure?

  Yes, most models feature a design where the internal temperature remains displayed for up to 48 hours after a power-off.

  7. Are there different configurations available?

  Yes, the series offers both horizontal (chest) models and vertical (upright) models with various capacities from 100L to 828L.

  8. What prevents unauthorized access to the stored samples?

  Each unit is equipped with a safety lock design to prevent unauthorized opening.

  9. Is the unit suitable for areas with unstable power supply?

  Yes, the freezers are designed with a wide voltage tolerance to operate reliably in different power environments.

  10. How are samples organized inside the upright models?

  Upright models like the DW-40L525 feature separate drawers (up to 10) to facilitate organized storage and minimize air exchange.

  11. What is frequency conversion refrigeration?

  In models like the DW-40L100, frequency conversion allows the compressor to adjust its speed, leading to higher energy efficiency and stable cooling.

  12. How does the freezer prevent frost at the door seal?

  The door frames are often heated to prevent frosting, ensuring a perfect seal and easy access to the samples.
