  • Silencers for suction air and for boiler stacks
  • Acoustic boiler house for HRSG
  • Soundproofed systems for evaporative towers, heat exchangers, ventilation fans, air conditioning plants
  • Noise enclosures for steam turbine, generators, pumps, compressors, and any type of machine
  • Single-block air-conditioned shelters for switchboards and electricity transformers
  • Soundproofed containers for generating sets
  • Personnel soundproofed booths for control rooms
  • Absorption and resonance silencers for civil, industrial and naval application

Gas turbine silencer inlet exhaust systems

CTM Ambiente designs and manufactures complete gas turbine silenced inlet exhaust systems for power plants and heavy-duty applications. The full package is designed in order to optimise the plant’s performance, minimizing pressure drop, heat loss and increasing the power plant’s noise limit efficiency.

The range of products CTM Ambiente supplies to the world market includes:

  • Steel supporting structures
  • Complete filter houses
  • Inlet and exhaust ducts and diffusers
  • Textile expansion joints
  • Thermal and noise insulation for the whole system
  • Inlet and outlet baffles type silencers
  • Rectangular or circular stacks

Absorbing baffles silencers

CTM Ambiente designs and manufactures absorbing baffle silencers for every installation. Absorbing baffle silencers are usually installed in inlet / outlet gas turbines, air conditioning plants and cooling towers to build ventilation in a wide range of temperature, flow and speeds.

CTM Ambiente’s absorbing baffle silencers are designed to be installed in a vertical or horizontal position. Modular absorbing baffles are made by a metallic frame containing mineral wool mattresses, and can be supplied complete with anti-icing, anti-rain grids, dampers and filter boxes.

Blow-off and vent silencers

CTM Ambiente provides blow-off and vent silencers for applications where gas or steam is vented under pressure to the atmosphere. The silencing effect is due to the controlled gas expansion, combined with an additional absorbent device fitted on the upper part of the diffuser. These silencers are usually installed in safety or relief steam valves in oil and gas plants, and in every application where there is an under pressure gas.

Engine silencers

CTM Ambiente’s endothermic engine silencers are designed to guarantee high attenuation in co-generation plants, gensets and ship engines. They are constituted by a cylindrical body in which a resonator associated with absorptive parts is fitted. CTM Ambiente can additionally provide spark arrestors, metallic expansion joints and complete exhaust lines.

Boiler houses, acoustic building and soundproofing enclosures

CTM Ambiente is able to design, build and install any type of enclosure to suit any customer’s needs. Its range of soundproofing enclosures has a steel structure and modular panels.

CTM Ambiente covers a wide range of needs and applications, from tailored canopies on equipment to huge acoustic buildings containing the entire plant or boiler houses on HRSG. Together with the enclosure, CTM Ambiente can also supply the soundproofed ventilation system, the electrical plant, the lighting plant and the fire-fighting system.

CTM Ambiente has been in operation since 1994, first as a division of CTM, an Italian leader in thermal and acoustical insulation market; in 2001, it became an independent company.
