NICHIREI INDUSTRIES CO.,LTD.

We design and produce gas-liquid separators using surface tension.

Our company has created an innovative gas-liquid separator with micro-grooves in collaborative research and development with universities. Previous gas-liquid separators used gravity, but our new device separates gas from liquid using surface tension. This is a completely new concept. Its features include compactness, high performance, and no need for a power feed or movable parts. Our centrifugal oil separator achieves a compact size and high-end performance thanks to its unique inflow shape. Our company has been striving to consistently design and produce quality custom-made refrigeration cycle units for home appliances and auto piping since its foundation.

[Product description] We have created an innovative gas-liquid separator with micro-grooves in collaborative research and development with universities. Previous gas-liquid separators used gravity, but this new device separates gas from liquid using surface tension. This is a completely new concept. This device is particularly effective for gas-liquid two-phase flow, which has a larger proportion of liquid than gaseous matter. This surface tension-driven gas-liquid separator offers a solution with features such as compactness, high performance, and no need for a power feed or movable parts. [Market share/Ranking] A gas-liquid separator incorporating surface tension effects is a world-first and our company’s exclusive technology. [Intellectual property] 1. Gas-Liquid Separator and Refrigerating Appliance Consisting of a Gas-Liquid Separator (Japan: Patent Nos. 4268994 and 5395358; China: Patent Nos. ZL200680042497.7 and ZL200910002127.6). 2. Number of applications for patents related to issues other than the above: five in Japan; one each in China and Korea. [Major facilities and equipment] Product development facility: three test devices for assessing the performance of gas-liquid separation. Production facility: two TIG welding machines.

[Product description] Centrifugal force-driven gas-liquid separator Our company’s unique compact, high-performance gas-liquid separator has been developed with a two-phase inlet port pipe. Materials for the main body can be selected from copper, stainless steel, aluminum, etc. Gas-liquid two-phase flow with a larger proportion of gaseous matter than liquid is more effective. [Intellectual property] 1. Gas-Liquid Separator and Refrigeration Unit Incorporating Gas-Liquid Separator (Japan: Unexamined Patent Application No. 2011-247575; China: Unexamined Patent Application No. CN102235783A). 2. Number of patent applications other than the above: one in Japan, one each in China and Korea. [Major facilities and equipment] Product development facility: three test devices for assessing the performance of gas-liquid separation. Production facility: two TIG welding machines.
