NMX-MES-30 · ENGINEERED TO ORDER — MOBILE ENVIRONMENTAL STORAGE CONTAINERS

Corrosion needs three things. The container denies one — for years.

Name: Mobile Environmental Storage Container
Brand: Neometrix

A stored article fails its first fit-check after months of doing nothing at all — because corrosion needs a metal, an electrolyte and oxygen, and coastal salt air, monsoon humidity and a hot store supply the one that matters: the moisture film that forms above roughly 50–60% RH. Hold the air dry and the reaction has no path. So the container is engineered around the moisture ledger — sized for the door, not the volume, because every opening debits it with a slug of ambient air — with desiccant dehumidification that keeps drying where cooling coils stall, a continuous vapour barrier, ducted air that leaves no dead zone, restraint built for road shock, generator-backed ride-through, and every hour logged — because a store that averaged 45% RH has preserved nothing. No delivered environmental storage container is claimed; the class is engineered to order for fleet storage programmes.

Overview

Most of an article's life is spent waiting.

Rotables and spares fly for hours and wait for years — in stores, at deployed bases, in transit between depot and squadron. The waiting is where they are lost, and the container exists to make the waiting harmless.

Illustrative of the class — interior of an insulated storage container photographed from the open doorway: bright white lined walls and ceiling, two runs of fresh grey steel racking down both sides carrying plain grey cradles and smooth unmarked cases, orange ratchet restraint straps drawn across each shelf, a rectangular air-distribution duct along the ceiling centreline with round diffusers, a small white sensor head on the far wall, clean pale floor, no people and no readable markings

Fig · 02 Inside — cradles, restraint for the road, ducted air to every corner, and a sensor that watches the corner nobody visits

The physics is a three-legged stool. Electrochemical corrosion needs a metal, an electrolyte and oxygen. You cannot take away the metal, and taking away the oxygen at scale is an inerting problem for sealed volumes. What a storage container can take away — reliably, cheaply, for years — is the electrolyte: the microscopic film of adsorbed water that appears on every surface once relative humidity climbs past roughly 50–60% RH. Below that line the electrochemistry has no medium to work in. Everything else in the machine serves that one idea.

So the sizing follows the moisture ledger. The question is never “how big is the box?” but “what gets in?” — infiltration past the seals, vapour driven through the panel, moisture carried in on the articles and their packaging, and above all the door. Every opening debits the ledger with a slug of ambient air, and on a monsoon morning that slug can carry more water than a whole day of leakage. Which is why recovery time is a specification, why the primary engine is desiccant dehumidification (still drying at low temperature and low absolute humidity, where a cooling-coil dryer simply stalls), and why a vestibule earns its space on a store that is opened hourly.

And the proof is the record. A container that held 45% RH for eleven months and 80% for one has not preserved anything — it has averaged. So temperature, humidity, door events and power state are logged continuously, alarms reach a person rather than a panel, and the downloadable history follows the article's storage life — the evidence that lets an engineering authority extend a storage period instead of stripping and re-preserving on suspicion.

The class is engineered to order for fleet storage programmes — shell, conditioning, racking, logging and the acceptance testing as one scope, built to the customer's article list. No delivered environmental storage container is claimed: the record is stated as it stands.

Specifications

Reference containers, built to the article list.

The parameters below describe reference containers. Envelope size, conditioning capacity, racking layout and autonomy all follow from three givens: the articles to be stored and their preservation standards, the climate envelope of the sites, and the duty cycle — how often the door opens.

Illustrative of the class — close view of the conditioning machinery of a storage container in a clean workshop: a compact desiccant dehumidifier in fresh grey paint with two insulated round ducts leaving its top, a small refrigeration condensing unit with a finned coil beside it, a filter housing with quick-release clips, a control panel with its face angled away from the camera, tidy conduit and cabling clipped to a painted frame, no people and no readable markings

Where environmental storage goes wrong

Sized for the volume, not the door — a container that recovers in six hours serving a bay that opens every hour. Cooling-coil drying alone — humidity control that collapses exactly when the weather turns cold and damp. A vapour barrier broken at the joints — the panel specification on paper, the leak in the corner. One sensor by the door — mapping never done, dead zone never found. Racking that survives standing but not the road — restraint sized for gravity, then asked to take transport shock. No autonomy — the outage that quietly runs the ledger backwards for six hours. Logging that begins at the alarm — no history, no defence of the storage period. Solar gain forgotten — a dark container in open sun acting as its own heater. And barrier bags asked to do a container's job — preservation packaging as a substitute for a controlled, monitored microclimate.

So the discipline runs the other way. The envelope is sealed and leak-tested, not assumed; the humidity engine is desiccant, sized to the ledger's debits; the air is ducted and then mapped with articles in place, because the corner at 70% RH is the one that fails. Restraint is engineered for the road. Power carries a stated ride-through, and alarms find a person. And the whole microclimate is logged continuously, so the storage period rests on evidence rather than on the day someone happened to look at a dial.

FAQ

Common questions.

Plain-language answers from the engineering team.

Q · 01 Why does humidity matter so much more than temperature in storage?

Because humidity is what completes the circuit. Corrosion is electrochemistry, and electrochemistry needs an electrolyte — a conductive medium in which ions can move between anodic and cathodic sites on the metal. On a stored article that medium is not a puddle; it is an invisible film of adsorbed water, a few molecules thick, that forms spontaneously on surfaces once relative humidity rises past roughly 50–60% RH. Below that band the film is too sparse to carry current and corrosion effectively stops; above it, the rate climbs steeply, and any salt or acidic contamination on the surface makes it climb faster still by making the film more conductive and lowering the humidity at which it forms. Temperature matters, but mostly through humidity: warm air holds far more water, and a cooling article in humid air can fall below its dew point and wet itself directly. Temperature also drives the secondary ageing mechanisms — elastomer hardening, grease separation, plasticiser migration — which is why a good store controls both. But if you can only control one thing, control the water: it is the leg of the stool you can actually kick away, and kicking it away is cheap enough to sustain for the years an article may sit waiting.

Q · 02 Why desiccant dehumidification rather than a refrigeration dryer?

Because of where each one stops working. A refrigeration (cooling-coil) dryer removes water by chilling air below its dew point so moisture condenses on the coil. It is efficient in warm, humid conditions — and it fails precisely where a store needs help most: as air gets colder and drier, the required coil temperature approaches and then crosses freezing, the coil ices, and useful drying stops. In a cold-weather store, or any store asked to hold a genuinely low humidity, the cooling coil simply cannot reach the target. A desiccant dehumidifier works differently: a rotor coated in a water-adsorbing material takes moisture out of the process air by adsorption, which does not care about dew point, then a small heated reactivation airstream drives the collected water off the rotor and dumps it outside. That gives it two properties this application wants: it keeps drying at low temperature, and it can reach low absolute humidity that coils cannot approach. The usual engineering answer is both, in their right roles — refrigeration to remove heat and take the bulk water out of a hot monsoon slug, desiccant to hold the final humidity band steadily and to carry the store through cold, damp weather. What matters is that the humidity duty is owned by the desiccant, so the specification holds in every season rather than only in the season the brochure photographed.

Q · 03 What does “sized for the door, not the volume” actually mean?

It means the design load is moisture ingress per day, not cubic metres. Think of the store as a ledger. On the credit side is the dehumidifier's capacity. On the debit side are four things: infiltration through seals and penetrations; vapour drive, the slow diffusion of water vapour through the panel itself under the pressure difference between humid outside and dry inside; moisture carried in on articles, packaging and pallets, which then evaporates into the store for days; and the big one, the door. Every opening exchanges a volume of conditioned air for ambient air, and on a monsoon morning at 90% RH and 32 °C that single slug can carry more water than the sealed envelope leaks in a day. So the honest specification is not “pull-down time from ambient” on a sealed box — that number flatters everyone — but recovery time after a defined door event, at a defined ambient, with the racking in place. Design decisions follow from it: dehumidifier capacity and control strategy, whether a vestibule or airlock earns its footprint on a store opened many times a day, door seal detail and closer discipline, and where the return air is drawn from so the machine sees the incursion immediately. Size for the volume and the store looks superb on handover day; size for the door and it still holds its band in year three, in the monsoon, with a busy squadron drawing spares from it.

Q · 04 What is a dead zone, and why is mapping mandatory?

A dead zone is a pocket inside the store where the conditioned air does not actually circulate — typically behind a full rack, in a bottom corner, against an outside-facing wall, or in the volume shadowed by a large article. The store's display reads 45% RH because the sensor sits in the moving air near the return; the dead zone sits at 70% and quietly corrodes whatever is stored in it. The physics is unforgiving: humidity control is an air-distribution problem as much as a dehumidification one, and stagnant air near a cold outer wall can even be sitting below its dew point. The engineering answer is ducted supply with diffusers positioned for the racking layout as it will actually be loaded, returns placed to sweep the whole volume, gaps maintained behind racks, and insulation continuous enough that no interior surface runs cold. And the proof is mapping: a survey with a grid of calibrated sensors distributed through the loaded store — corners, floor level, behind racks, inside representative cradles — logged over a period that includes door events and a diurnal cycle, so the store is characterised loaded and working rather than empty and sealed. Mapping is what turns a specification into evidence: it finds the dead zone while it is still a ducting change, sets where the permanent sensors belong, and gives the operator a baseline to re-check after any racking change. A store that has never been mapped has an opinion about its humidity; a mapped store has a measurement.

Q · 05 How does this differ from your shelters, preservation and climatic chambers?

Four machines, four intents — and the boundaries are deliberate. The field technical shelter is a workplace: it conditions air so people and equipment can operate at a deployed site, and it is judged on how it performs during a shift with people inside, doors moving and equipment dissipating heat. This container is a preservation microclimate: nobody works inside it, its job runs for years rather than shifts, and its specification is a humidity band and a logged history rather than a comfort envelope. The aero-engine preservation line treats the article itself — inhibiting internal surfaces of one engine so it can survive storage; this container conditions the air around many articles, which is the complementary half of the same fight (and a good programme uses both: inhibited articles inside a dry store). The climatic and environmental test chambers are the mirror image: they manufacture heat, cold and humidity deliberately, to prove an article can survive an environment. This container spends its life keeping that same environment out. Same psychrometrics, same sensors, same instinct for barriers and control — opposite intents. That is why the four sit in one franchise without overlapping: test it, treat it, store it, or shelter the people who work on it.

Q · 06 What do you build, what is bought in — and what is claimed?

Divided honestly. What Neometrix provides: the container — insulated panel shell with its continuous vapour barrier, thermal-break framing, transport frame and corner castings, compression-sealed doors and vestibules; the conditioning integration — desiccant dehumidification as the humidity engine, cooling and heating sized for the climate envelope and solar gain, filtration and ducted distribution engineered against dead zones; the racking, cradles and restraint rated for road shock and lashing loads, static-dissipative where electronics live; power distribution with shore and generator interfaces and a stated ride-through; the instrumentation, logging and alarms with downloadable history; and the acceptance work that makes it real — sealed-envelope leak testing, pull-down and recovery demonstration at the specified extremes, and temperature-humidity mapping with articles in place — plus installation, commissioning, documentation, training, spares and AMC, including build to the customer's specification and article list. What is bought-in certified: dehumidifiers, refrigeration units, sensors, data loggers and generators — proprietary equipment of established makers, integrated rather than imitated. What is the customer's: the articles, their preservation standards and the storage periods those standards permit. And the record, stated plainly: no delivered environmental storage container is claimed. The class is engineered to order for fleet storage programmes, container by container, around the articles it must protect.
