Accoustic Door

Acoustic door is developed on the basis of previous expertise and is constituted of robust section framework, 2mm cold roll steel exterior shell and 1.5mm cold roll interior shell, hollow packing seal, specially designed stainless hinge and industrial latch. 

By using section steel, acoustic door framework has an enhanced durability,so even after years of usage, the quality of it would remain the same. Exterior shell is made of cold roll steel and tack-welded in one direction to prevent surface from deformation. And strength intensive framework is used within shells to assure surface flatness and maintain the gap between the door and its frame. The dual hollow EPDM (Ethylene Propylene Diene Monomer rubber) packing seal has provided a compressing dimension longer than 10mm and thus ensure the durability of door panel and latch. Stainless steel hinge facilitates the process of assembly, installation, fabrication to avoid surface scratching. 

Acoustic Door with proven quality and delicate appearance is capable of reducing noise to an acceptable level and quite suitable for silencing engineering applications as well as acoustic enclosure parts.

Application 

Acoustic door has a variety of applications which could mainly be divided into two situations: prevent noise from transmitting to the outside or getting inside through the door.

The acoustic door is able to provide sound proofing in Power Generator Room, Pump Room, Electric Motor Room, Boiler Room, Test Room, Aero Engine Test Bench, Silence Room, Air Conditioner Room, Blower Room, Air Compressor Room, Restaurant Kitchen, Active Noise Room in the workshop. Theater, Recording Studio, Premium Meeting Room, Factory Security Room, Airport Control Room and Office, Silence Room Beside Noisy Traffic Road and Acoustic Testing Room. 

Advantage
Since acoustic door is quite suitable for engineering instances due to its small thickness, artistic appearance, magnificent acoustic performance and proven quality, we have already applied CLET acoustic door on facilities in need of soundproofing as gas turbine, aero engine test bed, and marine naval ship.
