NexxtBuilt in the shop. Proven before it ships.
RTU, PLC and analyzer packages, solar-powered enclosures, surge protection and backup power, designed to your spec, wired and bench-tested in a UL 508A listed shop, and delivered with as-built drawings. The crew on site connects conduit. They do not troubleshoot.
Eight things we build well.
Each line is a standard we have built many times, with a drawing set and a test procedure behind it. Custom work starts from one of these, not from a blank sheet.
RTU & PLC systems
Flow computers, RTUs and PLC racks for measurement, control and telemetry. Redundant controllers and managed Ethernet where uptime demands it. Programmed and simulated on the bench.
Analyzer packages
Methane and gas analyzer panels with sample handling, 4–20 mA and digital outputs, integrated with the site RTU and tested end to end before shipment.
Solar-powered enclosures
Array, MPPT controller, battery bank and DC distribution sized for the site's load and worst-week weather. Skid or pole mount.
Surge protection enclosures
Coordinated surge and lightning protection for I/O, power and communications, with the grounding design to make it work.
Backup power & DC UPS
24 and 48 VDC UPS systems and battery cabinets that keep the RTU and the link alive through utility outages.
Switch racks & shelters
Free-standing racks, sun shields and walk-in shelters designed for the field technician and the climate.
Telecom integration panels
Radio, router, satellite modem and DC power in one enclosure, pre-configured and labeled for a one-visit install.
Custom retrofit solutions
New controls and protection fitted into existing enclosures and skids when replacement is not the answer.
What ships, and what it went through first.
Hover the callouts on the panel. Every item on it has a line on the drawing, a test step and a label on both ends of the wire.

The factory acceptance test is a gate in our process. It is witnessed on request and documented in the install book with the drawing revision that was tested.
Point-to-point
Every wire checked against the drawing, both labels verified.
Power & protection
Supplies loaded, breakers and fuses confirmed, surge devices verified, ground continuity measured.
I/O simulation
Analog and discrete I/O simulated end to end. Scaling, alarms and fail-safe states proven.
Comms
RTU polled from a host over the real transport. Failover exercised.
Sign-off
Test record, photos and as-built revision into the install book. Panel sealed for shipment.
Send the spec or the problem.
A drawing set, a P&ID, or a photo of the enclosure you need to retrofit. We come back with a design and a fixed price.
