Won the "Minister of Economy, Trade and Industry Award" at the 2023 Energy Conservation Grand Prize for the water thermal source heating and cooling system "PEPO."

This is an air conditioning system that effectively utilizes temperature difference heat (renewable energy) in high temperature and humidity environments above 35°C room temperature.

PEPO is a cooling device that utilizes temperature difference heat, capable of dehumidifying and cooling without emitting waste heat. It is ideal for preventing heatstroke and managing heat in excessively hot indoor environments. Additionally, as a product that utilizes renewable energy, specifically "temperature difference heat utilization," it is also effective for energy-saving and power-saving measures. ■ No waste heat is emitted It cools using cold water and a heat exchanger, so no waste heat is produced. ■ Does not use refrigerant gas Unlike air conditioners or spot coolers, it does not utilize a refrigeration cycle. ■ Dehumidifies using condensation It does not increase humidity (absolute humidity) like evaporative coolers. ■ Wind speed can be freely adjusted It is equipped with a large fan (φ500) with airflow adjustment functionality. ■ Economical even when left on It consumes only 0.83 kW of power while providing significant cooling capacity. ■ Keep cool before the temperature rises with circulating cooling Its energy-efficient design allows for continuous operation with circulating cooling (intake airflow of 5,500 m3/h). ■ Can also be used for heating purposes By using hot water instead of cold water, it can provide heating as well. *Please feel free to contact us.

Stay comfortably cool even in high-temperature and high-humidity environments above 35℃! A high-capacity air conditioning unit that cools using water and a heat exchanger [also suitable for pre-cooling if the air conditioning is not effective].

PEPO is a cooling device that utilizes temperature difference heat, capable of dehumidifying and cooling without emitting waste heat. It is ideal for preventing heatstroke and managing high temperatures in excessively hot indoor environments caused by machine waste heat, radiant heat, and heat from the ceiling. It can also assist in pre-cooling for air conditioners. ~ The AirPEPO cooling device is perfect for manufacturing sites where open flames are strictly prohibited! ~ 【Do you have any of these problems?】 ■ The waste heat and radiant heat from machines make it too hot, and the air conditioner can't lower the temperature... ■ A spot cooler makes one person comfortable, but the exhaust heat actually raises the room temperature... ■ In environments where air conditioners are ineffective, using a high-capacity portable air conditioner only creates airflow without improving room temperature... ■ Evaporative coolers increase humidity, which is a major factor in heatstroke, raising the heat index... 【Isn't it possible to cool without relying solely on air conditioning?】 If it’s hot enough that the air conditioner is ineffective, shouldn’t we lower the room temperature to a level where the air conditioner works? With PEPO, there is no waste heat and it saves energy, making it ideal for pre-cooling. By pre-cooling, the air conditioner’s efficiency improves, and electricity costs can be reduced. *For more details, please feel free to [contact us].

"Cooling system using water as a heat source" explains a fundamental solution to high-temperature and high-humidity environments with indoor temperatures above 35°C, where machine exhaust heat and radiant heat also cause indoor temperatures to rise.

PEPO is a cooling device that utilizes temperature difference heat, capable of dehumidifying and cooling without emitting waste heat. It is suitable for preventing heat-related illnesses and managing high temperatures in excessively hot indoor environments due to waste heat from machinery, radiant heat, and hot air from ceilings. As a product that utilizes renewable energy, specifically "temperature difference heat," it is also effective for energy-saving and power-saving measures. When hot water is supplied, it can also be used for heating. ~ AirPEPO is ideal for manufacturing sites where open flames are strictly prohibited! ~ [Do you have any of these concerns?] ■ In factories where machines generate heat and temperatures exceed 35°C, air conditioning cannot lower the temperature... ■ With spot coolers, one person may feel cool, but the exhaust heat actually raises the room temperature... ■ In environments where air conditioning is ineffective, using a high-volume portable air conditioner only creates airflow without improving room temperature... ■ Evaporative coolers increase humidity, raising the "heat index," which is a cause of heat-related illnesses... Currently, based on examples that have resolved the above issues, we will explain the reasons why heat-related illness prevention often fails in environments where air conditioning is ineffective! * The materials can be viewed from [PDF Download].

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

Our company sells PDCE devices and the supports and fittings for installing these devices in various locations. The new lightning rod "PDCE Lightning Ball" is designed to "avoid" lightning strikes by incorporating features that make it difficult for lightning to approach, unlike traditional lightning rods. Its round shape and double structure with an insulator help suppress "welcoming discharge," which attracts lightning current. This lightning protection system complies with the lightning reception requirements of the "Building Standards Act." Rakurai Yokusei Systems Co., Ltd. https://www.rakurai-yokusei.jp/
