桑名金属工業 List of Products and Services

The new model is the "Chilled Tower CTS-A075M." For requests for the new catalog, please contact us. The catalog currently available features existing models. The new Chilled Tower integrates a chiller and a dry cooler, enabling hybrid operation suitable for outdoor temperature conditions throughout the four seasons and at any time of day. By setting the required chilled water temperature (10°C to 30°C), it automatically supplies stable chilled water with low power consumption. Additionally, the new Chilled Tower improves the COP with a new refrigeration cycle, providing a cooling capacity of 76 kW to 83 kW per unit. It can be connected with up to 25 units, accommodating over 1.5 MW of cooling. If you provide us with your usage conditions, we can help select the appropriate model and propose energy-saving calculations. Sustainability points of the Chilled Tower: Compared to continuous chiller operation, it reduces annual power consumption by approximately 54%, contributing to lower carbon emissions (continuous chiller operation refers to a scenario where the chiller operates year-round without the free cooling function of the Chilled Tower. Our calculation conditions are a supply water temperature of 20°C, ΔT = 5°C, cooling heat load of 56 kW, and weather conditions in the Tokyo area). On August 1, 2024, the piping equipment division of Protearial Co., Ltd. started anew as Kuwana Metal Industry Co., Ltd. under the capital of Okaya Steel Co., Ltd.

• Air conditioning equipment

The chilled tower is a structure that integrates a chiller and a cooling tower, automatically operating in hybrid mode to match outdoor conditions in spring, summer, autumn, and winter, as well as day and night, providing stable supply of chilled water from 13°C to 35°C with low power consumption. For details on the new model specifications, please contact us. The new model supports up to 1.8 MW with a connection option. The catalog published is for the current model. Sustainability points of the chilled tower: Compared to a typical chiller, it reduces annual power consumption by approximately 54%, contributing to low carbon emissions (based on our calculations, this is without the free cooling function of the chilled tower compared to a typical chiller). On August 1, 2024, the piping equipment division of Protearial Co., Ltd. started anew as Kuwana Metal Industry Co., Ltd. under the capital of Okaya Steel Co., Ltd.

• Air conditioning equipment

The snow melting mat is a mat-type outdoor snow melting device developed to ensure safety on sidewalks in snowy regions and to reduce the labor involved in snow removal. It adopts a non-spray type that connects to existing snow melting water pipes, eliminating the need for heating power. Furthermore, we are considering using tap water, hot water, and waste heat water for melting snow on stairs, preventing freezing on floors, and heating tanks in areas where open flames are prohibited. Please feel free to contact us with your requests. We would be happy to make suggestions. 【Features】 ■ Sidewalk snow melting using well water and groundwater ■ Melts snow at approximately 5 cm/h ■ Can be connected in series or parallel to melt snow over a wide area (up to 2 mats) ■ Can be rolled up and stored compactly when not in use ■ Easy to walk on without spraying water ↓ For detailed specifications, please refer to the catalog flyer. 【Introduction to some of our business activities (Piping Business)】 ■ Polyethylene piping system for gas ■ Fittings (malleable, stainless steel) ■ Flexible pipes and fittings ■ Chilled towers ■ Valves (segment ball valves) ■ Expansion tanks ■ Snow melting mats

• Safety and consumables

We have evaluation test data on the leak-proof performance of sheets using various slurries and powders. If you are particularly troubled by sheet leaks due to solids in ball valves, please feel free to consult us. Segment ball valves are stainless steel valves with an eccentric structure that excels in sealing performance and helps reduce lifecycle costs, featuring 90-degree opening and closing. We offer manual, high-torque electric drive, and air cylinder drive options. Sizes are available up to 300A. The electric drive version includes flood prevention specifications and variable opening and closing time specifications.

Prioritize free cooling for the production of chilled water in the medium temperature range, and if it is insufficiently cooled, chillers will back up the cooling. It is utilized for data centers, cooling of production processes, and water recycling, and is also appreciated for its space-saving and labor-saving aspects. Please make use of it for energy and water savings during the installation, expansion, or renewal of chillers, turbo chillers, and absorption chillers. We offer highly energy-efficient evaporative types, easy-to-maintain air-cooled types, and this new model. The photos and catalog included are of the current models.

Please inquire about the specifications of the new model.

• Refrigeration units, boilers, cooling towers

"Zetlock" is a mechanical type of pipe fitting developed for stainless steel piping. It features excellent corrosion and heat resistance, leveraging the characteristics of lightweight and strong stainless steel piping, making it a highly reliable fitting. A unique indicator that distinguishes between hand-tightening and final tightening allows for easy confirmation of any tightening omissions. 【Features】 ■ Reliable sealing ■ Strong connection ■ Prevention of construction errors ■ Prevention of forgetting final tightening (hand-tightening leak function) ■ Easy piping work *For more details, please refer to the PDF document or feel free to contact us.
