Sales and Support for T/R sets and Controls

NWL offers a complete range of spare parts, repair solutions, and field service for your NWL T/R sets and controls.  As a large manufacturer, we manage a spare parts warehouse for all our current products.  In many cases, we can fulfill next day deliveries for critical items.

Likewise, our Repair Department benefits from our fabrication capabilities.  We build our own cores, wind our own coils, and fabricate our own diode boards.  No other T/R repair company can do all that, which is why we can offer the most competitive pricing, fast delivery, AND high quality.  Among the repair options we offer are:

  • Emergency repairs (turnaround in 2 weeks or less)
  • Replace coils and rectifier only
  • Standard repair - replace worn out or damaged parts
  • Complete refurbishment to Better than Original™ condition

Our Field Service Department performs a full array of on-site functions, including:

  • T/R or PowerPlus start up assistance
  • ESP power supply checkup
  • Controller upgrades (hardware and software)
  • Troubleshooting and servicing damaged units
  • Operating and Maintenance training
  • T/R oil sampling and filtering

NWL has published a pamphlet entitled ESP Controls and Electrical Systems Troubleshooting Guide.  It is an excellent reference guide that provides an excellent overview of precipitator operation and fault diagnosis and is available via a link listed below.
