Mechanical, electrical, instrumentation, inspection, and building maintenance with excellence and safety.
Powertec provides comprehensive mechanical maintenance services for rotating and static equipment. Our team specializes in repair, overhaul, and replacement of components in steam and gas turbines, centrifugal and reciprocating compressors, process pumps, heat exchangers, pressure vessels, block and control valves, and conveyor systems.
We perform laser shaft alignment and coupling, in-situ dynamic balancing, predictive vibration analysis, and corrosion under insulation (CUI) assessment. All procedures follow API, ASME, and PETROBRAS N standards, with complete material traceability and up-to-date technical documentation.
Our team handles both scheduled preventive maintenance and 24/7 emergency response, ensuring maximum availability of critical assets with response times under 4 hours for plants in the Northeast region.
We perform medium and low voltage services, including industrial electrical installations, process automation, control panels, electric motors, and grounding systems. Our team is qualified to work in classified (Ex) areas per NR-10 and ABNT NBR 5410 standards.
We conduct infrared thermography for early detection of hot spots, insulation resistance measurement, turns ratio testing (TTR) on transformers, and commissioning of protection, control, and interlocking systems. We use asset management tools to plan condition-based interventions, reducing unplanned downtime.
We support large-scale electrical maintenance shutdowns, mobilizing teams of up to 50 professionals for disassembly, inspection, repair, and reassembly of panels and power systems within strict time windows.
Calibration, configuration, and maintenance of measurement and control instruments: pressure, temperature, flow, and level transmitters, online analyzers, control valve positioners, level and flow switches. Expertise in smart sensors with HART and Foundation Fieldbus protocols.
We work with programmable logic controllers (PLC) from major brands (Siemens, Allen-Bradley, Schneider), SCADA, DCS, and SIS systems. We perform control loop configuration, PID controller tuning, interlock logic implementation, and factory acceptance tests (FAT) and site acceptance tests (SAT).
We have our own NDT inspection team qualified per ISO 9712 and SNQTC at levels 1, 2, and 3. We perform visual inspection (VT), liquid penetrant (PT), magnetic particle (MT), conventional and phased array ultrasonic testing (UT/PAUT), industrial radiography (RT), and acoustic emission (AE).
We offer risk-based inspection (RBI) for asset prioritization per API 580/581, and static equipment integrity management per API 510, 570, and 653. We issue technical reports and opinions with repair and monitoring recommendations, updating equipment records per regulatory requirements.
Our inspection services are integrated with Powertec's AI platform, which uses computer vision and predictive models to automate result analysis and anticipate defect evolution, increasing inspection reliability by over 30%.
Preventive and corrective maintenance services in industrial infrastructure: metal roofing, high-performance industrial flooring, hydraulic and sewage systems, fire protection and suppression, safety signage and accessibility, and climate control for control rooms and offices.
We execute annual building maintenance programs with defined schedules, periodic inspections, and supplier and supply management. We meet the requirements of NR-23 (fire protection), NR-11 (forklift operator), and NR-35 (work at height), ensuring full compliance of facilities.
All activities follow rigorous safety procedures, with risk analysis (RA), work permits (WP), and continuous monitoring. Our professionals are certified in NR-10, NR-33, NR-35 and trained in confined space, hot work, and critical equipment operation.
