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 model 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 external 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 your usage conditions, we can help select the appropriate model and propose energy-saving estimates. 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 runs year-round without the free cooling function of the Chilled Tower. Our estimation conditions are a supply water temperature of 20°C, ΔT = 5°C, cooling heat load of 56 kW, and meteorological 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.

The chilled tower is a structure that integrates a chiller and a cooling tower, automatically operating in hybrid mode to provide stable chilled water from 13°C to 35°C with low power consumption, adjusted to external conditions throughout the seasons and times of day. For information on the new specifications, please contact us. The new model supports connection and can handle up to 1.8 MW. 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).

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 in 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 refrigeration units, and absorption chillers. We offer highly energy-efficient evaporative systems, easy-to-maintain air-cooled systems, and a new model. The photos and catalog included are of the current models.

The snow melting mat is a mat-type outdoor snow melting device developed to ensure the safety of 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. Additionally, 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, and we will make suggestions. 【Features】 ■ Sidewalk snow melting using well water and groundwater ■ Melts snow at approximately 5cm/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
