From basic audits to full project turnkey, we’re here to help.

Flexible Engineering Scope of Services

Engineering Studies/Audits

A.H. Lundberg is often requested to perform an audit on an existing plant system for a number of purposes, including increasing system capacity, system safety, system efficiency, improve stability of ease of operation, troubleshooting and interfacing one system with another or future system. Each audit is tailored to the specific need of the client and may comprise a number of the areas listed above.

Our specialty is the process knowledge of the technologies we provide. We utilize these technologies to benefit a plant in the review of individual systems including all types of waste gas handling systems, condensate/sour water stripping systems, evaporator systems, and heat transfer.
