Complete evaporation and crystallization trains built, wired and tested in the factory — shipped in ISO containers or on flat racks, lifted onto your foundation and hooked up to power, feed and discharge in days. From 25 kg/h containerized pilots to 10 t/h process skids, expanded by bolting modules side by side.
Reference ranges from published skid and containerized system data across heat-pump, MVR and multi-effect builds.
One skid carries the whole train — evaporator body, compressor, separator, pumps, piping and controls — prefabricated, tested and shipped as a single piece.
Feed tank → Preheater → Evaporator module (falling film / forced circulation) → MVR compressor or heat pump → Separator → Concentrate or crystallizer → Product / distillate — all on one skid frame with PLC cabinet & CIP station
Concentration and crystallization variants share one platform: the crystallization skid swaps the discharge end for a crystallizer and centrifuge; the scraper keeps heat surfaces clean on scaling feeds. Condensate returns as clean water; the compressor loop recycles every kilojoule of vapor latent heat.
Every skid starts from the same core set; corrosion package, crystallization end and pretreatment are added by duty.
Aggregated from published containerized and skid-mounted system data — indicative ranges for preliminary sizing, not a process guarantee.
Ranges aggregate published specifications from containerized heat-pump, MVR and multi-effect system suppliers; figures are indicative for screening and must be verified against your feed analysis, site power limit and logistics constraints.
Pick the platform by duty and utilities — the evaporator physics is the same, the packaging and energy source are not.
Energy figures follow published data for each platform; final selection needs your electricity / steam price ratio, footprint limit and discharge permit.
Published modular systems scale from laboratory pilots to containerized MVR process skids on the same delivery logic.
Anonymized configurations reconstructed from published supplier project data.
Engineering guides on skid delivery, pilot campaigns and the small-vs-large decision.
The skid is the packaging — these are the technologies and duties it carries.
This page aggregates published supplier specifications and project data (containerized heat-pump and MVR system builders, modular multi-effect suppliers, open-evaporation unit manufacturers) into an engineering screening view. All names are withheld; configurations are described generically. Figures are indicative ranges for preliminary sizing — final selection requires your feed analysis, site power limit, transport constraints and discharge permit.
Recurring questions from engineers weighing the skid route.
Skids win on schedule and certainty: 80–90% factory completion with FAT, 2–5 day hook-up, 10–15 days total installation versus 3–6 months of field assembly, and roughly 30% less civil works. Above roughly 10 t/h per train — or with layouts a container frame cannot hold — field-erected trains take over; below that, skids cut cost, schedule and interface risk.
Published systems span 25–300 kg/h containerized heat-pump units to 0.5–10 t/h MVR process skids. Expansion is by parallel modules: multi-skid plants run 10,000-t/y class duty 24/7, and open-evaporation containers scale the same way at 100 t/d per unit — capacity is added by bolting units side by side, not by rebuilding.
A level pad, three-phase power, and feed / discharge connections. MVR skids need electricity only — no live steam at steady state. Heat-pump units run fully electric with closed refrigerant loops and no cooling water. Modular multi-effect skids are the exception: they need live steam at 0.6–1.0 MPa from your boiler house.
That is what it is for: 20-liter sample campaigns measure boiling-point elevation and viscosity before the full-scale design is fixed, and the pilot runs the same evaporator body type as the production skid — so heat transfer and scaling behavior transfer directly. Crystallizing and scaling feeds additionally run scraped-surface pilot duty before material selection.
SS316L covers general duty; Duplex 2205 and 2507 handle high-chloride brines; TA1 / TA2 titanium and Hastelloy cover the extremes — a ladder that spans pH 1–14 with over 20-year design life. High-chloride systems also use stepped protection, for example titanium tubes with a 2205 shell.
80–90% of piping and electrical integration, static commissioning, and a witnessed FAT. Larger MVR skids add 3-stage anti-surge protection — alarm, control, trip — tuned at the factory, so site work is hook-up and start-up only, with remote diagnostics and cloud monitoring from day one.
Skid-mounted MED desalination for islands, platforms and remote sites: why low-temperature evaporation beats RO on difficult feed, the 70 C gypsum ceiling, GOR economics, and modular delivery.
Why 90-95% factory prefabrication, 50-60% shorter field installation, and 35-50% smaller footprints make skid-mounted MVR evaporators and crystallizers the default for modern plant upgrades – with sizing rules, materials selection,
