BACHMANN India has launched, for the first time in India, Acoustic Enclosures with a modular inter-locking Panel System. It boasts of the industry-minimum down-time for doing rapid installation and dismantling. It also provides inter-changeability due to its standardized panel geometry.
In a tie-up with NAP Acoustic South-East Asia Pvt. Ltd., the unique SOUND SNAP panel system is now indigenously available. Following many years of development, the SOUND SNAP system has found wide application in hundreds of installations. It has a proven track record for the complete range of noise control products of NAP SILENTFLO, all of which are tested at NATA registered independent laboratories. The range of supply applications consist of:
The BACHMANN Panel Filter Houses provide efficient filtration of air for Gas Turbines and Diesel Engines. Comprehensive filter product range is capable of meeting all requirements, up to the maximum levels of separation efficiency.
PULSE-JET filterhouses comprised of banks of cartidge filters are self-cleaned by means of sequential reverse-flow pulses of compressed air. Cartridges are available to suit all environments, and efficiencies in excess of 99% can be achieved.Evaporative Cooling Systems, lead to lead to increased power output and an improved gas turbine heat rate, particularly in warm and dry climates
Stack Cap Damper are typically employed to encapsulate adequate heat to ensure efficient start & working of the boiler. BACHMANN employs a unique coupling and counter-weight mechanism to make the design efficient and 100% independent of external drives, thus eliminating the possibility of dangerous pressure build-up in the system. They are self-opening at set pressure, and self-closing on reduction of pressure below specified, with quick open/shut-off feature.
These heavy duty constructions are extensively used in material handling application. They isolate or divert solid materials such as clinker dust and coal ash.
BACHMANN Poppet dampers are equipped with a Duplex Leaf-seal type arrangement ensuring 99.9% isolation even without a Seal Air system, Optionaly provided with internal heating arrangement to prevent build-up of sticky flow media, Quick shutopen feature is available on demand.
Turnkey Duct system components supply includes Silencers, Stacks, Support structures and Ductwork (including square to round transitions).
Duct SILENCERS are designedto achieve permissible near field / far field noise levelwith a touch-safe outside skin temperature while maintaining adequate strength to support Stack loads. The typical GE frame-6 silencer attenuates the gas turbine exhaust by-pass stack noise level to within 85dbA at 1 metre from the system perimeter
DUCTINGS, are available in a full range from simple carbon steel to high temperature alloy and stainless steel constructions. With a carbon steel outer frame the internally insulated ducts are typically clad with St/Steel 409 (or other st/steel materials) liner plates over a ceramic or mineral wool lining held together with a specially machined pin & washer arrangement. Externally insulated ducts require special attention to prevent thermal stress cracking.
BACHMANN India supplies a complete range of non-metallic expansion joints for applications ranging from low-temperature thermal plants, and high-dust cement mills to high-temperature steel plants. Backed by technical support of Bachmann USA (a founder member of EJMA), BACHMANN has developed multiple ranges of fabric expansion joints consisting of:
a) Elastoflex Expansion Joints Single membrane expansion joints for low temperatures.b) Ultraflex Expansion Joints High temperature range expansion joints for the utility industry.c) Ductflex Expansion Joints Heavy duty non-metallic joints for temperature upto 1400 deg.Cd) Gas Turbine Expansion Joints Patented designs for GT applicatione) Special Gaskets for high temperatures and GT applications.f) Pipe-penetration Joints
BACHMANN in association with Wahlco Group of USA has pioneered the supply and installation of Flue gas Conditioning systems in India. It allows coal fired boilers to burn a wider variety of coals, including low cost high ash content coals and low sulfur coals while avoiding the cost of scrubber installations all without affecting the performance of the fly ash particulate collectors (Electrostatic Precipitators).
Key Features:
Flue Gas Conditioning is a revolutionary technology to enhance ESP collector efficiency to levels consistent with the firing of high sulfur coals.Flue Gas Conditioning skids designed in association with Wahlco, Inc. (USA) reduces the resistivity of fly-ash, thus improving collector efficiency, especially for high-sulfur and high-ash coals common in India
Seats : Seats are made of a high Nickel alloy which enable self-cleaning Blades : The Blades are of an Airfoil Configuration which allow a minimum pressure drop without affecting performance Components : These are individually removable and are easy to maintain Drives : It enables quick Actuation and is available in all modes Electric, Pneumatic, Hydraulic, Manual Design : These are designed as heavy duty and abrasion-resistant
The TANDEM LOUVER DAMPER has an open cross-flow profile that creates very low pressure drop when fully open. 100% isolation is ensured by injecting pressurized air through a top or side mounted seal air fan & valve system
BACHMANN India is a specialist supplier of state-of-the-art three-way diverters used for controlling Gas Turbine exhaust flow either to the Bypass Stack or to the downstream HRSG. The latest generation of BACHMANN GFD is an integration of the best features of the original Bachmann (USA)and Metroflex (UK) designs the pioneers in this field. Diverters are available in both toggle drive and pivot drive options, covering the complete range: from boxes of small 1M sq. opening to the huge 7M sq. Frame-9FA size. Custom design options can accommodate a variety of aspect ratios, electric or hydraulic drive, circular or conical inlet, and internal or external insulation configuration with quick shut features.
STACK TRANSITION is a square to round transition piece comprising an internally-insulated carbon steel shell. All transitions, The from square to rectangular or round to round configurations, are all are designed as per requirement. Externally-insulated, stainless steel constructions are also possible.
STACKS, either self-supporting or with a four pillar external support-structure, for GT and HRSG applications are designed to the relevant international codes. Their modular design, insulated or bare, enables easy site erection with minimum down-time.
Butterfly Dampers are round louver dampers that facilitate both isolation and modulation. They find wide application in industrial ductings used for gas cleaning and process equipment.
The GSV damper design for achieving 100% crossblade gas isolation without employing sealair fan system is the original proprietory design of our partners the erstwhile Metroflex, UK. Very popular in application such as ESP inlet and outlet, it features a unique dual bulb-sealing system and an open bonnet.
A vent silencer, also known as safety valve & blow down silencer, is basically designed to meet the expanded flow requirements of steam & other high pressure gas venting systems. Vent silencers find wide applications in high pressure vents, steam vents, safety relief valve outlets, steam blow downs & purge outlets, etc
