205-5100 Series

The 205 industrial silencers are designed to cover a majority of Applications through a horsepower range of 200 to 5000, or a mass flow of 2.5 to 65 lbs/sec. Approximate capacities are based on average gas velocity through industrial silencers of approximately 10,000 ft/min; and will vary depending on pressure drop criteria.

Construction
All welded heavy duty steel Construction. Standard units are equipped with 125/150# ANSI flanged inlets and outlets. A variety of flanges or connections are available to meet customer requirements. Internals consist of special acoustical fiberglass packing adjacent to concentric perforated cylinders creating an annular passage design. In addition, special cone reducers and side inlets are available. Reducers allow a smooth transition where the line size is smaller than the inlet of the industrial silencer. Side inlets provide convenience of installation as well as the benefit of an additional 3 to 5 dB'A'in silencing.

Finish
Standard Finish is high heat silicone black or aluminum, depending on Material Options. Consult factory for optional coatings.

Other Information
May be installed vertically or horizontally.

Versatility
The 205 series is truly a versatile industrial silencer. In addition to standard engine Applications, it is extensively used in gas turbine, blower, compressors, andvacuumpumpApplications.

Notes
The attenuation values are representative for an intermediate industrial silencer.Peak attenuation will vary depending on industrial silencer sizes.

Thermal Information
The 501-5100 Series utilizes an acoustical and thermal insulated packed shell. At 900 degrees (F) exhaust temperature, the packed shell can provide significant reduction (up to 80 %) in the outer surface temperature depending on the Application and ambient conditions. This makes the 501 series an ideal choice for enclosures or small engine compartments. Additional outer thermal wraps are also available when lower surface temperatures are required. Consult factory for additional specifications and surface temperature analysis.

Catalytic Converter Combo Units

industrial silencers, industrial mufflers, industrial filters, GT Exhaust, GTE

The industrial engine market is now subject to current federal, state, and local emission regulations. Powertherm has the solution for your industrial emission concerns.

We provide a single "combo" unit that encompasses the cutting edge silencing performance of our mufflers coupled with catalyst elements secured inside the industrial silencer as one unit.

Our catalyst (oxidation and 3-way) elements reduce CO, NOx, hydrocarbons, and other harmful emissions up to 99%. Our catalyst elements are universal in size and can be interchanged on multiple size housings, which saves time and money. The convenience of stocking one size element simplifies element replacement and reduces catalyst inventory making it easier for field replacement and reordering.Give us a call and let Powertherm be the first and last call for your emission needs.

Safety Air Shut Off Valves

industrial silencers, industrial mufflers, industrial filters, GT Exhaust, GTE

•Barber Rig Savers 2"-11" valves available.
  •Intake Air Shutoff Systems for:
    •Diesel Engines
    •Gas Engines

Key Benefits
Rig saver: Air borne hydrocarbons present a threat to controlled diesel, engine operation. These hydrocarbons may be drawn into the air intake system causing the engine to accelerate out of control with the attendant risk of explosion and fire. The barber rig saver is a positive spring operated air/shut off device mounted in the air intake system and will positively block the air flow and stop the engine. These rig saver can be installed on any make, model and size diesel engine.
