Which unit fits your water, what every unit ships with, and how to read our numbers." source: "Alchemal — alchemal.com" --- # The N-Series: one platform, sized to your water Every N-Series unit is the same argument at a different size: put oxygen where the problem forms, and measure the recovery with instruments you can audit. This page says which unit fits your water, what every unit ships with, and exactly how to read the numbers we publish while the first units are still in build. ## Which unit fits your water One platform, sized to your water. The fit below is the design intent; the assessment confirms sizing against your water's surface area, depth, and condition, and says so in writing if no unit fits. - [N1 For ponds to a quarter acre: backyard, garden, and farm ponds Water to 1/4 acre Power 120 V outlet Mounting shore](https://alchemal.com/technology/n-series/n1/) - [N2 For golf, HOA, and community ponds to five acre-feet Water to 5 acre-ft Power 120/240 V Mounting shore](https://alchemal.com/technology/n-series/n2/) - [N3 For lakes of 5-20 acres, including deep, stratified water Water 5-20 acres Power single or 3-phase Mounting shore or barge](https://alchemal.com/technology/n-series/n3/) - [N4 For working lagoons of 1-10 acres carrying high organic loads Water 1-10 acre lagoons Duty high organic load Mounting shore or barge](https://alchemal.com/technology/n-series/n4/) - [N5 On the roadmap For municipal and industrial treatment basins and reactors, sized by flow and load Duty municipal + industrial basins Mounting catwalk skid, feeds the existing grid Status on the roadmap](https://alchemal.com/technology/n-series/n5/) ## Every unit measures its own work The measuring instruments are built into every unit rather than sold alongside it. Each one carries a research-grade optical sensor for dissolved oxygen, the amount of oxygen actually in the water and the single number that decides whether a pond is healthy, measured by a method the EPA recognizes, plus a sensor for water temperature. The N2 and larger units add two more readings, pH for the water's acidity and ORP for how well the water can break down waste. Every reading is tagged with the date its sensor was last calibrated, so the record holds up in front of a board, a regulator, or an inspector, not just on a dashboard. The unit also meters the oxygen it injects and, at the same time, measures the dissolved oxygen the water actually gained. The two numbers either agree or they don't, and both are in your record. That is delivered performance per installed unit, continuously, which no vendor in this category currently publishes. It's [the record we keep, either way the number goes](https://alchemal.com/technology/how-we-measure/), extended into the machine itself. ## Designed for pond water, not lab water N-Series units run on ambient air: no oxygen bottles, no gas deliveries, no supply contract. Where a water body needs more, an oxygen-concentrator factory option (N2 and up) multiplies output. Real ponds carry silt, weed fragments, and everything a storm washes in. The injection core has no moving parts in the water path and no fine membranes to clog; the smallest water passage is about 6 mm across, self-clearing by design. The one wear part is a plate that swaps out in under five minutes during a routine visit. What that buys you is the boring kind of machine: it runs, and the service visit is short. ## Runs itself, and tells you Cellular telemetry is included, with no SIM card or data contract on your side. The unit works offline for a month or more and backfills its record when coverage returns. Software updates arrive remotely and roll back automatically if anything is off. You get alerts for low dissolved oxygen, faults, and power loss; setup is done from a phone. Each unit holds the water to a dissolved-oxygen setpoint: it modulates down or shuts off when the water doesn't need it, which is where the power savings come from, and the larger units throttle in stages. Winterization is a single drain port, and [Stewardship](https://alchemal.com/stewardship/) handles it anyway. ## Safety and compliance Powered equipment beside water earns scrutiny, and the answers are designed in: an electrical panel built on the UL 508A path, a NEMA 4X (IP66) outdoor enclosure, GFCI protection, and a lockable disconnect. The documentation set for procurement and inspectors comes with the proposal. ## How to read every number on these pages - **Stated as fact:** what a unit is and ships with. Sensors, telemetry, ambient-air operation, mounting, connection types, design standards. True by design, not by test. - **Stated as a target:** every output, coverage, sound, and weight figure, each labeled "target" where it appears. Every figure marked "target" is an engineering target for units now in build. Targets are published so you can plan, not to impress you; they can move during production, and the measured value replaces each one when units ship. Changes are logged where the number lives. Pricing publishes when the first production units ship. - **Never stated without data:** delivered performance. Efficiency claims publish with clean-water test results to the recognized standard (ASCE/EWRI 2-06), cited, or they don't publish. The full rules are rung four of [the claims ladder](https://alchemal.com/technology/how-we-measure/). ## What arrives, and what Stewardship carries A restoration arrives as three parts, not a truckload of equipment: the shore unit, intake and return lines to placements chosen in the assessment (so oxygen reaches the depth where your problem forms, not just the surface), and the sensor station the whole promise stands on. The hardware is half the system. [Stewardship](https://alchemal.com/stewardship/) is the service around it: scheduled visits, sensor calibration, seasonal transitions, and the weekly record of what the water is doing. Your crew takes on nothing, and the record is yours either way, in the format fixed by [how we measure](https://alchemal.com/technology/how-we-measure/). ## Where the spec sheet is We're building and testing the first N-Series prototypes right now. Each tier page carries its engineering targets today, labeled as targets, so you can plan against real structure instead of emailing for numbers. When units ship, the measured values replace the targets line by line, with the changes logged. If a sizing question matters to your decision before then, ask in the [assessment](https://alchemal.com/assessment/) and you'll get the current engineering answers in writing. And if you'd like to follow along as we get closer to launch, [join the waitlist](https://alchemal.com/results/#follow) and we'll write as the first units reach water. ## Tell us what your water is doing.
