We developed an internal boiler cleaning robot, designed to enter through existing access openings and reach deposit build-ups between tubes in hard-to-access areas. The solution significantly reduced cleaning time and enabled the work to be performed more safely, minimizing personnel exposure to confined spaces and hazardous conditions. The system integrates precise positioning mechanisms using …
Typical scope
- Assembly and overhaul of pumps, gearboxes, fans, conveyors, rollers, heat exchangers, and auxiliary equipment.
- Laser shaft alignment, leveling, geometric control, and corrections for misalignment/vibration.
- Assembly and fitting: couplings, bearings, seals, pulleys, and belt tension/alignment.
- Controlled torqueing with records, marking, and verification of critical joints.
- Assisted start-ups: pre-commissioning, functional checks, no-load/load tests.
- Field diagnostics: basic vibration/temperature measurements, inspections, and condition analysis to define actions.
Deliverables
- Assembly and pre-commissioning checklists.
- Alignment, leveling, and geometric condition records.
- Torqueing records and critical joint control logs.
- Testing/commissioning protocols (as per scope) and condition report.
- Operational recommendations and an O&M; plan (including suggested spare parts and preventive actions).
Success stories
We designed and fabricated five chemical dosing skids, developing a custom solution for each application based on the chemical, required flow rate, process conditions, and operations/maintenance needs. Each skid included metering pumps, measurement/instrumentation elements, a control and protection panel, variable frequency drives (VFDs), and a stainless-steel skid structure suitable for industrial environments. We also …
We performed a unit replacement on boiler fans—equipment critical to the operation of the Recovery Boiler. The intervention included decoupling the rotor, a full disassembly of the assembly, and reassembly using new components, following safety procedures and dimensional control practices. We reviewed clearances and fit-up, carried out shaft alignment, and verified couplings and installation …
We designed and manufactured dozens of custom-made parts, combining turning, milling, CNC plasma cutting, and waterjet cutting to match each application’s requirements. We work primarily with stainless steel, duplex, and carbon steel, among other materials, ensuring dimensional accuracy and industrial-grade finishes. We develop components for measurement mechanisms and mounting adaptations, including links and coupling …
We supported 16 major shutdowns in pulp mills, delivering 400+ mechanical work orders—both planned and corrective—focused on safety, quality, and strict shutdown window execution. The scope included component repair and replacement, mechanical adjustments, shaft alignment, belt tensioning, weld build-up repairs, and controlled lifting/rigging activities. Works were performed on agitators, pumps, conveyors, and other pulp …
We delivered turnkey centrifugal pump installations, including detailed engineering of foundations and mounting bases, with more than 50 units installed. The scope covered site surveys, layout drawings, anchor design, leveling, and grouting as required for each pump. Execution combined civil works with mechanical installation, including laser shaft alignment, coupling adjustments, and tolerance verification. We …
