Built by an engineer who's lived in the engine room
NH3Edge was born from a problem I kept encountering in the field: ammonia refrigeration facilities relying on static inventory numbers that were often months or years old — while their operating charge shifted continuously with ambient temperature, production loads, and system changes.
I've spent years working in and around ammonia refrigeration systems — conducting compliance audits, developing PSM programs, sizing PRVs, facilitating PHAs, and watching facilities operate within uncomfortably thin margins above the 10,000-pound regulatory threshold without knowing it.
The consulting services at NH3Edge solve the documentation and compliance side. The NH3Edge monitoring system solves the real-time visibility side. Together, they give ammonia facilities what they've always needed: complete knowledge of where they stand — every second, not once a year.

Why I built NH3Edge
During a compliance audit at a cold storage facility, I calculated their ammonia charge using the IRC methodology — accounting for every vessel, pipe run, evaporator, and condenser. The result was 9,340 pounds. Their previous assessment said 8,800 pounds.
That 540-pound discrepancy wasn't negligence — it was the difference between a static calculation done on a winter day and an operating system measured in summer. They were 660 pounds from the PSM threshold and had no idea.
I started asking: what if they could see this number in real time? What if, instead of trusting a calculation that was 18 months old, they had a live dashboard showing exactly how many pounds of ammonia were in their system at every moment — broken down by vessel, trended over time, and automatically alerting them as they approached the threshold?
That's NH3Edge. Not a software product bolted onto general IoT infrastructure — a purpose-built system designed specifically for ammonia refrigeration, with the thermodynamic models and regulatory context built in from the ground up.
How we work
Precision Over Estimation
Ammonia inventory calculation is not guesswork. Every component-level calculation is documented, referenced to published thermodynamic properties, and defensible in an audit or courtroom.
Continuous Over Static
A once-per-year inventory assessment tells you where you were, not where you are. NH3Edge was built because the industry needed real-time data, and existing solutions weren't built for ammonia refrigeration.
Safety-First Engineering
Every recommendation we make — every PRV size, every PHA finding, every compliance program element — is made because it reduces the risk of a catastrophic ammonia release, not because it fills a checkbox.
Transparency Always
Our reports show our work. Calculations, assumptions, regulatory citations, and data sources are always documented. You should always be able to understand and verify what we delivered.
