The "KW-U" is a tube-type heat exchanger for drainage that is made of stainless steel 304, resistant to corrosion, long-lasting, and economical with pressure-resistant specifications. By indirectly flowing the supply water and warm wastewater, it achieves heat exchange (efficiency of 10-30%). This alleviates the burden on supply equipment (such as boilers) and improves durability. Additionally, by setting the pressure resistance to 0.4 MPa, it can also accommodate pressurized water. 【Features】 ■ Pressure-resistant specifications ■ Tube type ■ Alleviates the burden on supply equipment ■ Improved durability ■ Compatible with pressurized water *For more details, please refer to the PDF document or feel free to contact us.

"KOT" is a temperature control unit for faucets and showers that provides stable and safe hot water supply. It uses a circulation method to return the appropriately heated water supplied to the faucet or shower back to the tank. By mixing hot and cold water within the tank, it can supply water at a constant temperature. Additionally, the tank body features a vertical structure, allowing for space-saving installation. 【Features】 ■ Vertical, temperature-controlled circulation system ■ Mixing of hot and cold water within the tank ■ Ability to supply water at a constant temperature ■ Tank body has a vertical structure ■ Can be installed in a space-saving manner *For more details, please refer to the PDF document or feel free to contact us.

The "KHC-J" is a cooperative hair catcher suitable for piping systems such as filtration jets that do not get dirty. Its full thick plate structure makes it robust enough to withstand wear caused by the rotation of solids, which is characteristic of hair catchers. The "easy one-handle structure" that holds the lid at a single point allows for easy removal of the lid with just a slight loosening, reducing the hassle of work and leading to time savings. 【Features】 ■ Made of SUS304 for durability ■ "Easy one-handle structure" that holds the lid at a single point ■ Robust construction that can withstand wear from the rotation of solids ■ Compact design requiring minimal installation space ■ Ideal for piping systems such as filtration jets that do not get dirty *For more details, please refer to the PDF document or feel free to contact us.

The "KR" is a filtration machine with a stirring device that excels in maintainability and is designed for high-temperature use in all sizes. By directly stirring the sand, the cleaning ability is enhanced, allowing for the removal of dirt that cannot be washed away with backwashing alone. Thanks to the stirring function, the filtration capacity can be maintained, eliminating the need for sand removal, cleaning, or replacement. 【Features】 ■ Stirring device type ■ High-temperature specification for all sizes ■ No need for sand replacement ■ High durability, high pressure resistance, high heat resistance ■ Standard equipment includes sand inlet flange and sand outlet flange *For more details, please refer to the PDF document or feel free to contact us.

The "KHC-R" is a freestanding hair catcher that incorporates a large-capacity strainer capable of handling heavily contaminated filtered water. Made of SUS304, it is durable and, through oxidation film treatment, fully non-conductive on all inner and outer surfaces, allowing stainless steel to fully exhibit its inherent rust-resistant properties. Additionally, the "easy one-handle structure" that holds the lid at a single point allows for easy removal of the lid with just a slight loosening, reducing the hassle of work and contributing to time savings. 【Features】 ■ Fully exhibits the rust-resistant properties inherent to stainless steel ■ Easy one-handle structure that holds the lid at a single point ■ Full thick plate construction ■ Sturdy design that withstands wear from the rotation of solid objects ■ Incorporates a large-capacity strainer capable of handling heavily contaminated filtered water *For more details, please refer to the PDF document or feel free to contact us.

The KC603 is a pressure-free hot water tank that circulates while heating water through an internal circulation device, functioning as an instant water heater. Thanks to its combustion device, it can accommodate various fuels such as A heavy oil, kerosene, waste oil, sawdust, and wood pellets. Due to the large storage capacity of the hot water tank itself, it also serves as a storage tank, eliminating the need to install a separate storage tank that is essential for conventional boilers. 【Features】 ■ High efficiency ■ Built-in storage tank ■ Compatible with various combustion devices ■ Large double-opening doors ■ Usable without qualifications or registration *For more details, please refer to the PDF materials or feel free to contact us.

The "KWS" is a hot water heater made of SUS304, known for its durability, featuring pressure resistance that overturns the common understanding of low-pressure types with a maximum operating pressure of 0.2Mpa. Heat exchange pipes are arranged vertically throughout the entire body, significantly increasing the heat transfer area while allowing water to flow in and out both vertically and horizontally, thoroughly recovering heat and achieving a reduction in fuel and labor costs of approximately 10 to 40% for heavy oil and wood. By treating the welding burn during manufacturing with an oxidation film and fully insulating both the inner and outer surfaces, the stainless steel can fully exhibit its inherent rust-resistant properties. 【Features】 ■ Reduces fuel and labor costs for heavy oil and wood by approximately 10 to 40% ■ Made of durable SUS304 ■ Pressure resistance that overturns the common understanding of low-pressure types ■ Full insulation of both inner and outer surfaces with oxidation film treatment for welding burns during manufacturing ■ Fully exhibits the rust-resistant properties inherent to stainless steel *For more details, please refer to the PDF document or feel free to contact us.

At Kyowa Industrial Co., Ltd., we handle a nozzle clog prevention unit that drips from the injection nozzle into an air reservoir, ensuring no nozzle clogs. By individually providing a water level sensor (water level detection tube) and an injection nozzle (chemical injection tube), we maintain stable performance. Additionally, the failure conditions (such as air depletion) can be visually confirmed, preventing catastrophic damage such as pump overload leaks. The chemical injection machine currently in use can be reused. In addition to the electrode rod method, a photoelectric sensor method is also available. 【Specifications】 ■ Maximum operating pressure MPa: 0.5 ■ Materials ・ Protective cover: SUS304 ・ Gauge: Acrylic/PVC ・ Valve: U-PVC ・ Tube: TS ・ Flange: TS *Product introduction video https://www.youtube.com/watch?v=kEWcPopk8aw&feature=youtu.be *For more details, please download the PDF or feel free to contact us.
