OPTIMINATOR Two-Stage Mist Eliminator

In-Line Unit with Removable Mesh Pads

Remove entrained droplets in two mesh pad stages before the gas reaches the fan, stack or downstream equipment.

Mist Eliminator Description

REQUEST PDF CATALOG MIST ELIMINATORS

The Torch-Air OPTIMINATOR is a two-stage in-line mist eliminator for industrial exhaust and process gas. It is installed in the duct and removes entrained chemical droplets, liquid aerosols and the particulate they carry.
The unit is a complete housing with a flanged inlet and outlet, two mesh pad stages, an access door and a drain, supplied in vertical or horizontal configuration. The first-stage pad takes the bulk of the liquid load; the high-efficiency second-stage pad captures the finer droplets that pass the first stage. Both pads are removable for inspection, cleaning and replacement.
The mesh pad stages operate without continuous liquid recirculation. For sticky or high-fouling mist, a periodic wash-down system with removable spray headers can be added. An optional third-stage HEPA filter captures remaining fine particles. Filter specification and suitability are confirmed for the application.
Housing and media materials are selected for the mist chemistry and temperature. Replacement pads for the OPTIMINATOR and for other equipment are supplied separately: see Mesh Pad Mist Eliminators.

Two-stage collection

The first stage removes larger droplets and most of the liquid load; the high-efficiency second stage polishes the remaining fine mist.

No liquid recirculation

The mesh pad stages operate without continuous liquid recirculation. Media and face velocity are selected to balance collection efficiency and pressure drop.

Vertical or horizontal installation

Vertical and horizontal in-line housings fit trunk ducts, risers and retrofit spaces.

OPTIMINATOR Benefits

Service and Options

Both pads are reached through the access door for inspection, cleaning or replacement of each stage.

Removable spray headers with adjustable nozzles wash accumulated contaminants from the pads. Recommended for sticky or high-fouling applications.

An optional third-stage HEPA filter captures remaining fine particles. Filter specification and suitability are confirmed for the application.

Removable mesh pads

Option 1: periodic wash-down

Option 2: third-stage HEPA filter

Design Features

Flanged inlet and outlet

Round flanged connections for installation in the duct; custom flanges and transitions on request.

Drain section

Housing geometry directs collected and wash liquid to the drain rather than into downstream ductwork.

Reference general arrangement of a HURRICANE separator

Removable spray headers

Headers and nozzles are removed from outside the housing for inspection or cleaning.

Pressure monitoring

A differential-pressure gauge or transmitter indicates media condition and airflow restriction.

Corrosion-resistant construction

Thermoplastic, FRP or metal housings with corrosion-resistant media.

OPTIMINATOR Configurations

-1-

Standard two-stage unit

Two removable mesh pad stages in a vertical or horizontal flanged housing with access door and drain.

-2-

With periodic wash-down

Removable spray header for each mesh pad stage; manual, timer or PLC-controlled wash cycles.

-3-

Three-stage unit

Available on request. When HEPA filtration is specified, the HEPA filter is installed as the third stage after the two mesh pads.

Spheres of Use

OPTIMINATOR units remove chemical mist and liquid droplets from exhaust before the fan, stack or downstream control equipment.

Electroplating and metal finishing

Hard chrome, decorative chrome, anodizing, pickling and plating-tank exhaust.
Chemical processing

Acid mist, caustic mist, reaction-vessel ventilation and process exhaust.
Battery manufacturing

Acidic and alkaline process mist, washing and formation-area ventilation.
Semiconductor and electronics

Corrosive wet-process exhaust and compatible final-polishing applications.
Food, pharmaceutical and industrial washing

Water mist, rinse systems and compatible process aerosols.
Duct and equipment protection

Less chemical buildup in ductwork and lower loading on downstream scrubbers or filters.

QUICK SELECTION BY SECTOR

Substances Captured

Typical contaminants for mesh pad collection. Suitability is confirmed for the actual concentration, droplet size and materials of construction.

The Working Principle of the OPTIMINATOR

HURRICANE flow sequence from lower inlet through two separation stages to top outlet

1. Entry. Mist-laden gas enters through the flanged inlet and is distributed across the media face.

2. First stage. Larger droplets strike the fibers of the first-stage mesh pad and are removed from the gas stream.

3. Second stage. Smaller droplets follow the changing gas path through the high-efficiency pad and contact its fibers.

4. Coalescence and drainage. Captured droplets combine into larger drops that drain from the pads to the bottom drain.

5. Optional third stage. Where specified, a HEPA filter after the two mesh pad stages captures remaining fine particles.

6. Exit. The cleaned gas leaves the unit and continues to the fan, stack or downstream control device.

Specifications

Ranges marked “reference vertical two-stage units” apply to the units in the dimension table below. Horizontal and three-stage arrangements are dimensioned in the project drawings. Media, materials and options are confirmed for each project.

Reference Dimensions — Vertical Two-Stage Units

The dimensions below apply to reference vertical two-stage configurations. Horizontal and three-stage arrangements are dimensioned individually in the project drawings. A — inlet / outlet diameter. B — housing width across the access door. C — overall height, flange face to flange face. D — housing length, from the access door side to the back of the housing. E — overall length, including the access door

Wash-down option for the units listed: one nozzle per stage, 3/4″ spray header, 5.3 GPM per header during a wash cycle. Dimensions in inches are standard reference sizes. Final certified drawings are produced for the selected configuration, material, flange standard, access arrangement and wash-down package; do not use catalog dimensions for fabrication or installation.

Modifications and Sizes

Reference models cover 500 to 10,000 CFM (approx. 850–16,990 m³/h). Higher flows are handled by project-specific arrangements.

Vertical and horizontal configurations are available. The standard unit has two mesh pad stages. A three-stage configuration is available on request, with HEPA used as the third stage when specified. Housing and media materials, flange standard and options are specified for each order.

Final dimensions and connection positions are stated in the project drawings.

OPTIMINATOR Design

The unit consists of a housing with flanged inlet and outlet, two mesh pad stages, an access door and a drain section. Stage 1 is a removable mesh pad; Stage 2 is a high-efficiency mesh pad. When HEPA filtration is specified, the HEPA filter is installed as the third stage after the two mesh pads. With the wash-down option, each mesh pad stage has a removable spray header with one adjustable nozzle, connected to the wash-water supply outside the housing.

Operation and Wash-Down

The mesh pad stages operate without continuous liquid recirculation. A local or remote differential-pressure gauge indicates media condition and airflow restriction.

The access door and removable pads allow inspection of media, seals, spray nozzles and drains; each stage can be cleaned or replaced separately. Replacement pads are supplied to order.

With the wash-down option, an operator starts a short wash cycle when differential pressure or the maintenance schedule indicates cleaning, or a timer or PLC opens the wash valve at set intervals without removing the media. Brief cycles limit the volume of wash water to be collected or treated, and the housing directs it to the drain rather than into downstream ductwork.

Wash frequency depends on contaminant concentration, stickiness, chemical crystallization, airflow and media density.
