Rotaserv sources spare parts and new cryogenic turboexpanders for oil & gas, LNG and industrial gas operators across the MENA region. We work with manufacturers in this space to provide MENA operators with a local, responsive supply point — something the market currently lacks.
Cryogenic turboexpanders are precision machines operating at temperatures down to −270°C. They are the core equipment in LNG liquefaction plants, air separation units, NGL recovery processes, and hydrogen liquefaction. When they fail, there is no simple substitute — you need the right parts from the right source.
What the MENA market currently lacks is a local, specialist supply point for these machines. Operators typically go back to a European or North American OEM, deal with long lead times and high freight costs, and wait. Rotaserv is working to change that — building sourcing relationships across multiple cryogenic turboexpander manufacturers, without being tied to any single one. That means we can find you the right source rather than the one we happen to represent.
If you operate a cryogenic turboexpander and need spare parts, a quote for a new unit, or help identifying components — contact us. We will find the right source and come back with a straight answer on availability and cost.
The more detail you can provide, the faster we can respond. Useful information includes: manufacturer name, model number, serial number, plant name, part number (if known), or a photo of the nameplate. If you don't have any of that — tell us the application and we'll work from there.
These machines appear wherever a process requires deep refrigeration or energy recovery from a high-pressure cryogenic gas stream.
Turboexpanders cool natural gas to −162°C for liquefaction. They are a core component in baseload LNG plants and FLNG units. MENA's growing LNG and gas export capacity is driving new investment in these machines.
Recovering ethane and heavier hydrocarbons from natural gas requires deep chilling. Cryogenic turboexpanders provide the refrigeration for turboexpander-compressor NGL recovery processes at gas plants across Libya, Algeria and the Gulf.
ASUs producing nitrogen, oxygen and argon for refineries, hospitals and industrial customers across the Gulf rely on cryogenic turboexpanders for the deep refrigeration cycle. There are ASUs in nearly every major UAE and Saudi industrial zone.
Hydrogen liquefaction and helium recovery plants operate at even lower temperatures and demand the most precise cryogenic turboexpander engineering. A growing area of investment as MENA governments pursue clean energy infrastructure.
Our sourcing capability covers the full range of what operators typically need — from a single bearing set on an emergency call to a complete replacement unit for a planned upgrade.
Radial and thrust bearings — including active magnetic bearing (AMB) components on modern units — are among the most frequently replaced items. We source OEM and compatible equivalents with material certification.
Cryogenic impellers operate at extreme speeds and temperatures. Replacements require precise dimensional matching and material traceability. We work with manufacturers to supply these to specification.
Seal failure is the most common cause of unplanned shutdowns on cryogenic turboexpanders. We source complete seal assemblies and seal kits — typically the items with the longest OEM lead times.
For end-of-life replacement or new project procurement, we manage the full process — identifying the right manufacturer, managing the order, and handling import logistics into the destination country.
Whether you need parts now or want to establish a supply relationship before you need them — contact us. We respond to every inquiry directly, not through a ticketing system.
