Precedent1

Silencer installation example

This is the most standard NS type silencer installation example. Even if there are obstacles in the surrounding area, it is possible to determine the dimensions according to the fit.

Precedent2

Installation example of silence elbow

This is an installation example of a silencer elbow. Standard R dimensions are available, but can be changed according to site requirements. In addition, split delivery of vertical split, horizontal split, and slack split is also possible.

Precedent3

Sound insulation wall installation example

Installed to reduce noise transmission from nearby machines to nearby houses. We determine the specifications after careful design to determine how much effect is required, and then construct them.

Precedent4

Ventilation rattling measures example

This is a noise-reduction louver designed for ventilation and galling. Because of the trap structure, a relatively large effect can be expected.

Precedent5

Chiller measures example

This is an example of installing a muffler on the discharge side and a muffler hood on the suction side. Design in consideration of noise source size, installation conditions, allowable noise, etc. Take great care not to affect the capabilities of the features.

Precedent6

Example of outdoor unit measures

This is a countermeasure example for a building gusset outdoor unit. As in this case, we design only necessary equipment. “We don’t sell things we don’t need.”

Precedent7

Example of roof fan measures

The noise of the roof fan is surprisingly high. In this case, we will make a proposal that maximizes the effect in a small space.

Precedent8

Example of fan cover production

It is a cover of the kitchen exhaust fan installed on the rooftop. Each is designed according to the dimensions of the equipment. In this case, the muffler on the discharge side was also integrated. A fan was installed at our factory and delivered.

Precedent9

Soundproof cover installation example

Enclosed including the blower installed outdoors and surrounding ducts. We will design after conducting field surveys in detail.

Precedent10

Examples of cooling tower measures

This is an example of installing a muffler louver on the suction side of a cooling tower. Can be freely designed according to the size of the suction surface.

Precedent11

Example of floor mounting package measures

For floor-standing packages, for which noise countermeasures have been considered difficult, we will propose countermeasures according to each situation.

Precedent12

Examples of cooling tower measures

NS type silencer installed on the discharge side of the cooling tower installed on the roof. Noise Reducer’s strength is to satisfy the noise reduction performance without affecting the blower performance. Various types of outer plates, punching and sound absorbing materials are available to meet various requests.
