Serving the Oil & Gas Industry
Oil and gas equipment operates in some of the harshest environments on earth. High temperatures, electrical noise, corrosive atmospheres and nonstop duty cycles place extreme stress on every component in the system. When a transformer or coil fails, drilling stops, pumps shut down or monitoring systems go dark; and downtime becomes expensive fast.
Custom Magnetics builds transformers, inductors and coils engineered to withstand the electrical, thermal and mechanical demands of upstream, midstream and downstream operations. For over forty years, we have supplied magnetic components for drilling rigs, pipeline infrastructure, refineries, compressor stations and industrial control systems.
Transformers for Demanding Oil & Gas Applications
Standard catalog magnetics rarely meet the isolation, durability or mounting requirements of oilfield and processing equipment. Our engineering team works from your drawings or collaborates with you to develop a winding solution that matches your voltage, current, insulation and environmental needs.
Laminated core transformers support rugged, line‑frequency applications such as:
- Motor control centers
- Pump and compressor control systems
- Power conditioning for instrumentation
- Isolation for hazardous‑location monitoring equipment
Toroidal transformers offer compact size, low radiated field and high efficiency, making them ideal for:
- Portable field diagnostic equipment
- Pipeline monitoring electronics
- Control panels with tight space constraints
- Low‑noise environments such as measurement skids
Ferrite core transformers handle the high‑frequency switching used in modern oil & gas power electronics:
- Switch‑mode power supplies for control systems
- DC‑DC converters in remote telemetry units
- Gate drive transformers for variable‑speed drives
- Power modules in refinery automation systems
Coils and Inductors for Reliable System Performance
Oil & gas electrical systems generate significant noise from motors, drives, pumps and switching equipment. Sensitive instrumentation and communication systems depend on clean, stable signals.
We manufacture air core, ferrite core and laminated inductors designed for EMI/RFI suppression in control circuits, filtering for pipeline monitoring and SCADA systems, current sensing in pump and compressor controls, and harmonic mitigation in industrial power supplies. Our winding methods control stray field, saturation behavior and linearity so your components perform predictably under normal operation and fault conditions.
Built for Extreme Environments
Oil & gas equipment must survive heat, vibration, moisture, dust and corrosive atmospheres. Our components are engineered with materials and construction methods that support long‑term reliability, high‑temperature insulation systems, moisture‑resistant potting and encapsulation, corrosion‑resistant hardware and finishes, and reinforced mounting and terminal options. Every transformer and coil ships with full material traceability and documentation. Our ISO 9001:2015 certification ensures consistent, audited processes from prototype through production.
Supporting Your Project Timeline
Oilfield and refinery projects run on tight schedules where a missing transformer can delay a startup or stall a maintenance shutdown. We stock commonly used magnet wire sizes, core materials and insulation systems to support fast turnaround. When you need a design revision, prototype iteration or accelerated lead time, our team responds quickly with real engineering support.
