Dust collection

Dust collection systems for demanding industrial processes.

Engineered bag filters, electrostatic precipitators and hybrid systems - from process design and manufacturing to installation, commissioning and retrofit.

Select the right technology. Build it around your process.

Every plant is different. We evaluate your process, dust properties and operating conditions to recommend the most reliable, maintainable and cost-effective dust collection solution - then engineer and deliver it end to end.

Bag filters

High-efficiency fabric filtration for fine particulate control in dry, high-volume gas streams. Configurations include pulse-jet, reverse-air and online-cleaning systems with proven media selection and cleaning controls.

Electrostatic precipitators (ESP)

Robust particulate removal for high dust loading and high-temperature applications. Can be designed for single- or multi-field operation with rapping systems and advanced power control.

Hybrid ESP-baghouse systems

Combine ESP front-end collection with baghouse polishing to achieve stable performance across variable loads and tighter emission requirements.

Designed for your operating conditions

Process conditions

We consider your process layout, fuel or raw materials, batch/continuous operation and transient events.

Gas volume & temperature

Systems are sized for your gas flow range, temperature profile and potential for upsets or bypass.

Dust characteristics

Particle size distribution, resistivity, moisture, abrasiveness and stickiness inform technology and design details.

Emission targets

We design to meet your project requirements and applicable local regulations.

Installation constraints

Footprint, structural limits, lifting access, tie-ins and phasing are built into the solution.

Engineering, manufacturing and commissioning - one accountable team.

  1. Process design

    Process evaluation, technology selection, CFD & calculations, P&IDs and general arrangement.

  2. Equipment manufacturing

    In-house fabrication with traceable materials, QA/QC, shop assembly and FAT.

  3. Site installation

    Civil coordination, mechanical erection, electrical & I&C integration.

  4. Commissioning & retrofit

    Performance testing, optimization, operator training and retrofit upgrades for existing systems.
