Case Study · Regulatory Landscape
Mapping pressure vessel rules state by state.
A global leader in HVAC systems needed to understand how refrigeration pressure vessels are regulated across U.S. states. Building on an earlier national study, Prescouter examined eight outlier states in depth over four Intelligence Briefs and summarized the other 42.
The Client
The client is a globally recognized leader in heating, ventilation and air conditioning systems and solutions. It wanted a clear picture of how U.S. states regulate refrigeration pressure vessels to inform strategic planning.
The Challenge
Two common paths.
Eight exceptions.
An earlier Prescouter study in 2024 found that most states either adopt a version of the national mechanical code or align directly with pressure vessel certification standards. Eight states were exceptions, developing their own frameworks for refrigeration equipment and pressure vessels.
-
Codes
Code editions
Modern or historic versions.
-
Outliers
Eight states
Each with its own framework.
-
Scope
Related equipment
Refrigeration, boilers, vessels.

The Outcome
A national view for strategic planning.
Prescouter detailed how eight states regulate refrigeration equipment, boilers and pressure vessels, and whether each references modern or historic editions of national codes and standards. A high-level overview of the remaining 42 states covered the editions of key regulatory documents, giving the client the inputs to build a U.S. regulatory landscape for strategic planning.
