TOPTECH
Brief Introduction of Toptech
Toptech Environmental Engineering Co. Ltd. (hereafter called TOPTECH) was registered in February of 1998, by a group of engineers and started as a specialized company in acoustic engineering. Although TOPTECH is young, yet it is experienced, professional, energetic and aggressive. At present, TOPTECH main business activities are Noise and Vibration control in Gas field related facilities, Industrial plants and Commercial buildings. () 87 2
TOPTECHs scope of services include the design, supply, fabrication, delivery, site erection and commissioning of noise control equipment either on individual or turnkey basis. TOPTECHs profession and accumulated experience in acoustic engineering are closely related to the following areas: - I) In Environmental Noise Controls
1. NG vent-stack silencers, inline silencers
2. Cogeneration and incinerator plants
3. Gas turbine and diesel engine driven generators
4. Industrial manufacturing plant rooms
5. Heavy duty ventilation systems of ID & FD fans
6. High pressure steam, air and gas release silencers and
7. Large cooling tower systems etc.
II) In Architectural Acoustics
1. Full anechoic and semi-anechoic rooms, Recording studios.
2. Multi-function halls and cinemas
3. Acoustic treatment for walls of offices and buildings
4. A/C plant rooms of low-rise and high-rise buildings
5. Supply and return A/C ducting systems
6. Supply and exhaust systems for underground car parks
7. Floating floor systems
8. Acoustic barriers for highway and high-speed railways etc.
Besides, TOPTECH is agent and licensor for acoustic products of Aeroacoustic Corp. of USA. As a licensor we also manufactures noise & vibration control equipment under licensee agreement. We are also agent for A/D Fire Protection Corp. (also Canada) for acoustic spray material named AD Type I. With melting point over 985, and being a Class I fire resistant material, it is excellent for noise control for both industrial and commercial plant rooms. Besides, it is also good for thermal insulation and condensation control. We are also representatives, agents or distributors of products of the following companies: Aeroacousti Corp.AD Fire Protection Corp. AD Type I 985 Applied InternationalPolymer TechnologiesEmpire Acoustical Sys. Dustex Corp. The following is the list of major and typical projects done during the last 4 years. TOPTECHs expertise and products are outlined in separate sheets attached which help clients further understand her engineering capability.
