[Maintenance Work Example] Duct Repair Work

[Maintenance Work Example] Duct Repair Work

A duct has been installed on the chiller for heat dissipation! The direction of the exhaust can now be adjusted.

We would like to introduce a case study of duct repair work that we conducted. We confirmed the installation location of the chiller on-site. Ducts were installed on the chiller for exhaust, and valve installation work was carried out. This allows for adjustment of the exhaust direction, enabling seasonal adaptation. We received feedback from the customer stating, "The request was to prevent the summer heat, but the work also successfully addressed the winter cold at the same time." [Case Overview] ■ Industry: Automotive Parts ■ Subject: Duct ■ Request Details: Duct repair work ■ Construction Duration: 1 day *For more details, please refer to the PDF materials or feel free to contact us. Key service areas: Mie Prefecture, Kitasei District, Chusei District (surrounding Mie).

Spiral duct

Spiral duct

We deliver products that excel in quality and economy for air conditioning and exhaust ducts!

"Spiral ducts" are products that offer excellent rationalization for air conditioning and exhaust duct work in offices and residences, with outstanding quality and cost-effectiveness. They have the following excellent features: - High strength The flanges that form the spiral duct have a high reinforcement effect, making them suitable for high-speed ducts, dust collection ducts, and smoke exhaust ducts. - Low friction loss and leakage Spiral ducts have high roundness and a smooth inner surface, resulting in extremely low resistance. Additionally, they are equipped with sturdy lock seams formed by machine processing, and it is known that their leakage is only about 1/1000 compared to square ducts. - Quick construction time The connection work for spiral ducts is simple, and their ease of installation in ceilings and other areas significantly reduces construction time. Furthermore, because they are manufactured in factories, their quality is stable, ensuring reliability in construction. - High cost-effectiveness Spiral ducts are mass-produced as standard products in factories, making them inexpensive. Additionally, they can deliver the required air volume with a smaller surface area compared to square ducts, which reduces insulation construction costs. *For more details, please refer to the related links or feel free to contact us.*
