Engine and Compression Services

MSAPR compliance isn’t a one‑time project. Engines must stay compliant as loads, fuel, and operating conditions change.
Spartan Controls and Signet deliver practical MSAPR solutions; from AFR control and catalyst systems to emissions testing and reporting, designed to meet requirements without sacrificing reliability or driving unnecessary cost.
Beyond initial compliance, we help operators:

• Maintain emissions performance over time
• Extend catalyst life and reduce replacement costs
• Protect uptime while meeting regulatory limits

Not sure which engines need upgrades and which don’t?
Let us review your fleet and build a compliance strategy that works today and remains sustainable tomorrow.

Catalysts play a critical role in emissions compliance, but premature replacement is one of the largest hidden costs in MSAPR programs.
Spartan Controls and Signet provide full‑lifecycle catalyst management, helping operators maintain emissions performance while extending catalyst service life and reducing total cost.
Beyond supplying new catalyst elements, we help operators:

• Evaluate catalyst condition with non‑intrusive testing
• Restore performance through controlled cleaning processes
• Track catalyst health and plan replacements before compliance is at risk

When catalysts reach end of life, precious‑metal recovery options help offset future costs turning a compliance expense into a managed asset.
Not sure if your catalyst needs replacement or just attention?
Let us assess your catalyst performance and recommend the most cost‑effective path forward.
