Description
The Meling DW-HL series of ultra-low-temperature freezers differs from competitors by lower energy consumption, high capacity and lower operating costs.
New technologies. The classic cooling system is combined with a unique energy-efficient design that provides low power consumption and noise level during operation.
Energy efficiency and environmental friendliness. The combination of a world-famous brand compressor with a separate evaporator, combined heat exchanger, optimized separation system and highly efficient thermal insulation reduces energy consumption by 40%.
Noise-reducing design. The silent cooling circuit in a complex with a floating frame and a sound-absorbing compressor compartment provide the quietest work.
Three-dimensional thermal insulation. Ultra-low-temperature freezers of the DW-HL series have the increased thermal insulation made on technology of double foaming. On 6 sides, the thermal insulation of the freezer compartments is reinforced with vacuum VIP panels. The inner door is insulated. And the outer door has a patented thermal insulation design.
More storage. Features of a design allow to use internal volume effectively. For example, in the freezer DW-HL858S you can store up to 69,000 cryotubes of 2 ml.
