New chilled tower reduces annual electricity costs by approximately 54% compared to constant chiller operation.
Sangawa Metal Industry Chilled Tower CTS-A075M
For the production process, data center air conditioning, and cooling water for DLC servers: approximately 39% lighter than the current model, about 40% reduction in installation space, and using R32 as the refrigerant.
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.

basic information
Prioritize free cooling for the production of chilled water in the medium temperature range, and if cooling is insufficient, the chiller will back up the cooling. Additionally, the compressor will be controlled by PLC and inverter according to outdoor conditions. As a result, the annual operating hours of the compressor are reduced, leading to a longer lifespan. The chilled tower operates with a higher COP when the outdoor temperature is low and the supply water temperature is high. Even in regions with high average temperatures, free cooling can be utilized at night when temperatures drop. Contributing to energy savings and the SDGs. 【Solving problems like these!】 ● Reduction of carbon dioxide emissions ● Reduction of electricity costs ● Insufficient cooling tower capacity during summer ● Difficulties in managing cooling tower water quality ● Negative impact on product quality due to temperature rise of chilled and cooling water in summer ● Regulations on groundwater extraction ● Regulations on water supply volume for waterworks ● Increased burden of sewerage fees ● Measures against condensation water due to overcooling ● Limitations on installation space for cooling equipment The chilled tower has been available since 1989, with over 800 units in operation.

Company information
Our company is a young organization established on August 1, 2024, as a separate entity from Protearial Co., Ltd.'s piping equipment business. However, its roots can be traced back to Tobata Casting Co., Ltd., which was founded in 1910. When we launched our first product that same year, we cast it with the wish for "greater strength, smoother surfaces, and more beautiful curves," giving rise to the "Hyotan" mark. For over 100 years, we have continued to produce cast products under the testament of tradition and trust. Today, we manufacture and sell not only fittings and valves but also sealed diaphragm expansion tanks, semiconductor flow control devices, and cold water supply equipment. Furthermore, we take pride in our comprehensive capabilities, which improve on-site conditions through our technical expertise, support systems, and quality control measures, enabling us to meet societal needs such as efficient energy use and the realization of a safe and secure society. Although we are a young company, we cherish tradition while continuously providing new value to the industry in line with customer needs and market changes. We are committed to making efforts to meet our customers' expectations in the future, and we sincerely hope for your continued support.
