Energy Efficient Ultra Low Freezers from B Medical Systems
In recent years, the end-users of medical refrigeration products
worldwide have started focusing more on the energy efficiency of
laboratories due to the increased costs of electricity, regulations,
and awareness related to the environmental impact. In particular,
Ultra Low Temperature Freezers (ULTs) can be one of the most
energy-intensive pieces of equipment in a laboratory, for instance,
an average 25-cubic foot ULT unit uses approximately 20 kWh of
energy per day –as much as a small house[1]. B Medical Systems, a
pioneer in medical refrigeration technology has launched new Ultra
Low Freezers (Fig 1) designed to deliver superior energy efficiency
without compromising the security of the samples stored.
This superior energy efficiency has been achieved through frost-reduction along with a combination of various key factors listed below:

Ultra Low FreezersInner doors open
Natural Gas Refrigerants: B Medical Systems Ultra Low Freezers rely on the cascaded refrigeration system using two natural refrigerants – R170 and R290. R170 (Ethane) along with R290 (Propane), also known for its capabilities to yield more capacity with lower wattage, with its zero Ozone Depletion Potential (ODP) and a very low Global Warming Potential (GWP), increases the overall cooling efficiency while at the same time minimizing environmental impact
Inner Doors: B Medical Systems Ultra Low Freezers are designed with two inner doors made of aluminium that reduce cold air loss and heat conduction, when the outer door is open. These doors also close sections of the freezer, in a way that cold air does not spill out of the entire ULT when only one shelf needs to be accessed, thereby resulting in better energy efficiency.
Insulation� and� Gaskets: Vacuum insulated panels along with polyurethane foam form a thick insulation layer, which further minimize heat conduction through the walls of the cabinet. Our gaskets are made of silicon lips and foam, which provide strong sealing along with good thermal insulation in comparison with the traditional cavity-based gaskets and reduce frost build up further increasing energy efficiency.

The energy consumption values of B Medical Systems Ultra Low Freezers are shown in Fig 3 and the energy consumption values for various conventional Ultra Low Freezer models available in market can be found in Fig 4. The energy consumption values for the competitive models are based on publicly available information from the respective manufacturers. On average, the existing leading conventional Ultra Low Freezer models in the market consumes around 15.6 KWh/24hrs.
