Product advantages

. Origin import compressor with more stable performance.
. Microcomputer control, nonvolatile operation, memory-maintained function, digital temperature display.
. Direct-cooling refrigeration of evaporator coil plus pre-embedded refrigeration evaporator can prevent pipeline corrosion due to long-term use.

 User-friendly design

. Optional padlock ensures sample safety.
. Height-adjustable shelf divides the chamber into different sized storage spaces, which maximizes storage efficiency in case of long-term use.
. Painted steel made exterior and interior, beautiful and durable, rust-proof and corrosion-proof.

 Independent double temperature control

· MDF-548D's double chambers with independent temperature control enables different temperature settings and separate defrosting without sample moving-out.

 Security operability

. Nonvolatile memory, memory-maintained function, digital temperature display.
. In case of power failure, press "Buzzer" button, display of current temperature will last for 5 seconds. Once the power is recovered, the freezer will return to the settings (nonvolatile memory temperature, alarm settings, etc.) before power failure.
