Brazilian hermetic compressor specialist Embraco says it has overcome a significant hurdle for retail refrigeration with the development of a compressor that adjusts to the voltage of the product it is supplying.
The manufacturer said: “Although the market is full of products running on more than one voltage, this has always been a challenge in the refrigeration industry. So for equipment like refrigerators, freezers or refrigerator counters, voltage transformers are needed, significantly increasing the cost of the system and the space required in the final product.”
Embraco said it has overcome the technological difficulties involved with such a product to develop a ‘compact, complete and commercially feasible solution.’
It has launched a system comprising a compressor developed specifically for the purpose, and an electronic circuit board which recognises the input voltage being applied to the product, automatically adjusting the voltage supplied to the system loads (compressor, fan, defrost resistance and lighting).
The compressor, which holds five patents, will allow retailers to better calculate their inventory to meet demands of peak consumption, the firm said.
The first dual voltage option for refrigerators has been launched in Brazil, a country where there are two standard voltages: 127 V and 220 V.
Initially the compressors are being configured for domestic refrigerators and freezers but Embraco will also offer models for light commercial applications, such as refrigerated display cases.
