The "MSS Series" is a simple device equipped with a single hollow fiber UF membrane module. The application for concentrating microalgae and phytoplankton separates algae from the culture water through the 0.01 µm pores in the hollow fiber membrane, thereby concentrating the algae. The cross-flow filtration method, which circulates the culture solution, minimizes damage to the algae and achieves high concentration. The device is designed for seawater applications and can be selected from three models based on processing capacity. ★Processing tests with culture solutions are available on the official website★ Contract testing, sale of small test modules, and rental of testing equipment 【Effective Separation and Concentration of Algae】 ■ Minimal damage to algae and stable quality ■ UF membrane is less prone to clogging due to the cross-flow filtration method ■ Energy consumption is about half compared to centrifugation ■ Continuous processing and automation of operation are possible ■ Filtrate can be reused as sterile water ■ Membrane modules can be selected from cellulose acetate (CA) membranes and polyethersulfone (PES) membranes 【Differences in Membrane Types】 The highly hydrophilic CA membrane is less prone to fouling and is effective for long-term operation. The PES membrane has high initial permeability and is suitable for situations where quick processing is desired. *Please feel free to contact us for more details.*

The "E mizu Shower System" is a system that enhances heat exchange efficiency and contributes to energy savings by spraying pure water (RO water) mist on the outdoor units of air conditioning and refrigeration systems, utilizing the cooling effect of water. It achieves significant reductions in power consumption and CO2 emissions in facilities using large commercial outdoor units. It is patented as a watering device for outdoor units using RO water. 【Features】 ■ Reduces power consumption of outdoor units ■ Unique system that removes scale components before spraying Pure water (RO water) is sprayed after removing scale components from the water using reverse osmosis membranes (RO membranes). This prevents scale attachment and corrosion on the aluminum fins of outdoor units. ■ Six models with varying water production capacities ■ Two types of spray nozzles By using both mist nozzles and fan nozzles, it maximizes the use of latent heat of evaporation for effective spraying. ■ Efficient automatic operation Automatic control of spraying based on outdoor humidity (ON/OFF with weekly timer) Control of spraying volume based on outdoor temperature (spraying volume can be set in five levels) Rain stop function for spraying (with rain sensor) ■ Can be used for spraying in summer and as humidification water for air conditioning in winter ■ Seasonal maintenance included after installation
