Line Traps and Choke Coils

Some of the most common specialized electromagnetic coil applications for the industrial equipment sector are line/wave trap choke coils used in high-voltage (HV) applications. These critical coil devices are commonly installed in commercial power lines and other HV transmission lines. These industrial coil devices are engineered to impede the transmission of specific electrical frequencies into unwanted locations, such as system substations. 

Engines, Generators, and Emissions Systems for Agricultural and On-Highway Vehicles

Modern diesel engines, power generators, and their associated emissions systems rely on custom electromagnetic coils built for performance in the toughest of commercial applications. For example, diesel fuel injection, air intake metering, combustion monitoring, and various other powertrain functions are all electronically controlled in today’s industrial equipment.

A multitude of specialized sensors and precision sensing devices are installed throughout the transmission and powertrain systems of modern on-highway and agricultural vehicles. This is to ensure proper performance and reliability in conjunction with the engine’s output, and also to integrate various auxiliary systems that are powered by the vehicle’s engine or generator. Additionally, highly complex electronic emissions systems are installed on virtually all modern industrial vehicles to maximize efficiency while minimizing the commercial operation’s carbon footprint.
