[Soundproofing System] Silencer / Directly Above Duct

[Soundproofing System] Silencer / Directly Above Duct

Soundproof system suitable for building multi-air conditioning systems, chiller units, etc.!

We would like to introduce the "silencer and vertical duct" that we handle. A "silencer" is a device that reduces noise by attaching sound-absorbing material to the outlet of a noise-generating equipment, absorbing reflected sound within the duct until its exit, and reducing energy loss due to distance attenuation. Products without sound-absorbing material are referred to as "vertical ducts." In addition to the noise reduction effect from distance attenuation, they are used as wind direction guides to prevent the performance of equipment from being compromised when outdoor units are installed closely together. 【Features】 ■ Maintenance doors and window frames are designed according to equipment specifications and site conditions. *For more details, please refer to the PDF materials or feel free to contact us.

Flexible Air Conditioning Duct "Dacton"

Flexible Air Conditioning Duct "Dacton"

It is easy to transport to the site, and also easy to store in inventory.

"Dakuton" is a flexible air duct that supports two types: insulated and non-insulated. The insulated type uses aluminum film with fiberglass in the outer material, enhancing heat resistance and durability. The non-insulated type is fire-resistant and does not have PVC coating, so it does not emit harmful gases even in the event of a fire. [Features] ■ Insulated Type - Uses high-elasticity steel wire coated with copper, improving duct strength by incorporating winding pitch. - Insulation performance is enhanced by using 18kg/m3 25mm glass wool as insulation material, among other features. ■ Non-Insulated Type - Coated with aluminum and polyester in a two-layer structure, making it resistant to tearing. - Packaged in a compact form in an 85cm cardboard box, making it easy to carry and store, among other features. *For more details, please download the PDF or contact us.

[Case Study] Lower price than standard products! We will install large-diameter duct piping!

[Case Study] Lower price than standard products! We will install large-diameter duct piping!

Lower price than standard products! We will install large-diameter duct piping!

A food company has decided to install large-diameter duct piping due to the expansion of their manufacturing line. Since the piping will carry exhaust gases containing solvents, it is necessary to use stainless steel ducts. They have requested to keep costs as low as possible. Issues: 1. A φ500 stainless steel duct must be installed from the manufacturing building to the outdoor scrubber over a distance of 150m. 2. With stainless steel spiral ducts, leaks occur at the crimped joints. 3. If standard stainless pipe products are used, only thick-walled specifications are available, which increases costs and weight. 4. Since this work will be done simultaneously with other construction, it is necessary to devise a work schedule that fits within the construction period.
