Compare OXYMAT oxygen generator configurations for hatchery, broodstock and fish-farm applications. Prepare a brief covering demand, pressure, utilities and backup.
An oxygen generator for a hatchery or fish farm should be selected from a defined gas-demand brief. Tank volume alone is not enough to specify one. Ask the aquaculture designer to establish the oxygen requirement and delivery arrangement, then compare the generator, air supply, controls and backup as a complete package. This guide covers equipment procurement for aquaculture; it does not prescribe water-quality targets or fish stocking densities.
An on-site generator produces oxygen-enriched gas. The tank-side equipment and controls determine how that gas is introduced into the water. A generator quotation alone does not establish the performance of an entire hatchery oxygenation system. Put the gas outlet conditions and the receiving equipment's requirements in the same specification, and assign responsibility for their interface.
| Part of the project | Question to resolve before ordering |
|---|---|
| Demand assessment | What continuous and peak gas flow does the aquaculture design require, at what purity and delivery pressure? |
| Generator and air supply | Which compressor, air treatment, receiver, controls and gas monitoring are included? |
| Distribution and water-side equipment | Who specifies the pipework, oxygen introduction equipment and dissolved-oxygen monitoring? |
| Power loss or maintenance | What alternative supply and changeover arrangement will protect the operation? |
| Handover | Which outlet and integrated-system checks will be witnessed, by whom and under what operating conditions? |
OXYMAT identifies broodstock and hatchery work among the applications for its compact oxygen range. Its manufacturer page distinguishes integrated, integrated silenced and compact configurations. Compare the exact offered model; features of one version should not be assumed for another.
| Manufacturer configuration | Published family capacity | Purchase check |
|---|---|---|
| Compact integrated | 5–20 L/min | The published package includes an air compressor, dryer and oxygen tank. Confirm the selected model's complete scope. |
| Compact integrated silenced | 5–10 L/min | A silenced cabinet is offered. Ask for model-specific sound data at the proposed installation conditions. |
| Compact | 5–40 L/min | Check the external air-supply package and any optional oxygen monitor rather than assuming they are included. |
These are published family ranges reviewed on 5 October 2026, not a sizing recommendation or a guarantee for every operating condition. Obtain rated flow, purity, pressure, power and ambient limits for the exact configuration. VVON lists the integrated model family, silenced family and compact family.
If a supplier quotes flow in Nm³/h while another uses L/min, ask both to state their reference conditions and provide a comparison on the same basis. Also compare the complete electrical load of the proposed package, including air preparation and auxiliary equipment. The generator cabinet's nameplate alone may not describe the full installation.
Use actual delivered-gas invoices, electricity rates, operating hours and maintenance quotations. Request separate costs for the generator, supporting equipment, installation, consumables, planned service and backup. Model the expected workload and a lower-utilisation case. A manufacturer case study or a saving claimed at another farm is not a site-specific payback forecast.
For higher demand, review the wider OXYMAT catalogue with the same brief. The existing industrial oxygen and nitrogen guide covers broader gas-supply decisions. Do not scale a hatchery proposal simply by multiplying the number of tanks.
Start with the designer's gas-flow, purity and pressure requirements, then compare the exact generator and supporting equipment. The OXYMAT compact range includes configurations intended for hatchery and broodstock applications, but suitability depends on the complete site brief.
The selected capacity and configuration, air compressor and treatment, monitoring, installation, delivery and service scope affect the offer. Ask for an itemised quotation and separate the generator from distribution, water-side equipment and backup provision.
Do not assume it does. Power interruptions, maintenance and equipment faults remain design considerations. Have the responsible aquaculture team define the alternative supply, monitoring and response arrangements before committing to the generator purchase.
Send VVON your hatchery or fish-farm oxygen brief, including the demand assessment and existing equipment. Ask which supply, installation and support responsibilities VVON can include in the proposed project. Current availability, pricing and delivery require confirmation.
