Ammonia Refrigeration

Why This Role Is Worth Your Time

Own the plant’s cold chain on a 12‑hour night shift. You’ll run, maintain, and document a modern NH₃ system so production hits temperature, quality, and uptime goals. If you like hands‑on work, crisp procedures, and leaving equipment better than you found it, this is a solid move.

What Makes This Location Great

Night shift means focused rounds and fewer interruptions—perfect for techs who like completing work the right way. You’ll manage a clean, well‑labeled engine room with strong safety culture, clear SOPs, and parts support. Cross‑training and certification support are part of the deal.

Why This Location Works

• Quick I‑75 access for easy commutes and vendor service.

• Average one‑way commute around 20 minutes—shorter than the U.S. average.

• Generally affordable market with rents below national medians.

• Close to Dayton for shopping and services; Great Miami River Trail and parks nearby.
