Inspected machines, not yard rust

Refurbished and used ammonia compressors

Refurbished Grasso compressors and used ammonia refrigeration plants show up in Search Console because buyers want capacity without a new-package lead time. The risk is buying a painted casing with unknown hours. We sell inspected, remanufactured, or workshop-overhauled machines — not a photo from a scrap yard.

Refurbished, remanufactured, and used

Used means the machine ran somewhere and has been cleaned and inspected. Refurbished means wear parts have been renewed to a stated scope. Remanufactured means a full strip, measured clearances, new seals and bearings (and typically valve plates or shaft seals), and a test run where the frame allows it.

Ask for the scope in writing. “Refurbished” without a clearance sheet is a used machine with a wash. We would rather lose a sale than send a rotor that still has thrust-face smear.

When a used plant is the wrong buy

A complete used ammonia refrigeration plant can be cheaper than greenfield — until vessels are out of code, evaporators are blocked, or the compressor hours are a guess. Buy the compressor from a workshop that will stand behind the rebuild, then decide if the vessels are worth moving.

If you searched “used ammonia refrigeration plant,” send photos of vessels, nameplates, and the engine room. We will say whether you want a refurbished compressor into your existing plant, or a turnkey install with selected used vessels.

Questions plants ask first

Do you have refurbished Grasso compressors in stock?

Availability changes with workshop throughput. Ask with the frame you need (RC-11, RC-12, V-series, or screw package). We will quote a remanufactured unit or an overhaul of your machine — whichever is faster.

Can I run a used compressor without an overhaul?

Only if inspection, oil, seals, and alignment check out. Unknown-hour machines should be stripped or at least seal-and-bearing serviced before they see your charge.

Will you install the machine after sale?

Yes. Alignment, oil charge, leak test, and staged load-up are the difference between a delivery and a working plant. See installation and overhaul pages for that labour.

Planning a compressor overhaul or plant retrofit?

Tell us about your plant.

We will scope the right Grasso, Sabroe, or multi-brand ammonia approach — from a single compressor swap to a full plant overhaul.
