What Aquarius Technologies does

Aquarius Technologies is an Australian proprietary limited company headquartered in Acacia Ridge, Queensland, founded in 1989, that designs and manufactures the ULTIMA water treatment controller platform and the AquaReporter cloud-based remote monitoring system. The company serves operators of cooling towers, swimming pools, potable water systems, wastewater/trade-waste streams, post-harvest wash tanks, and — increasingly — APAC data centres, with a customer mix spanning SMB aquatic operators through to industrial and enterprise facility owners. The core ULTIMA hardware is a 7-inch colour resistive touch-screen controller with up to 13 outputs, modular firmware variants per vertical (Cooling Tower, Swimming Pool/U-Series, Potable Water, Wastewater/UTD, Post-Harvest), proprietary Accessory Timer / Inhibitor-Bleed Optimisation, and fuzzy-logic ORP/pH control. The companion AquaReporter platform provides 4G/Wi-Fi/Ethernet-connected multi-site monitoring, SMS/email alarming, Auto-Report compliance reporting, Modbus HLI and 4-20mA LLI integration to BMS/SCADA, and 2-Factor Authentication.

Aquarius monetises through three streams: one-time hardware sales (controllers, sensors, pumps, parts and consumables, with a 36-month controller warranty); recurring AquaReporter Web Access subscriptions bundled with 4G modems; and professional services covering custom configuration, free consultancy, and BMS/SCADA integration engineering. The go-to-market is consultative and sales-led — quote-based pricing, direct phone/email enquiry handling, Australian-based technical and service teams — complemented by a service-provider channel via AquaReporter multi-controller accounts and a forthcoming self-serve online parts store. The company is privately held, has no disclosed external investors, subsidiaries, or M&A activity, and has operated continuously for over three decades under the founder/management-led Aquarius Technologies Pty Ltd entity.

Revenue model

1. Hardware sales — ULTIMA controllers, sensors, probes, pumps, parts & accessories: One-time sale of proprietary Aquarius ULTIMA controllers (Cooling Tower, Swimming Pool, Potable Water, Wastewater, Post-Harvest variants), plus a wide range of branded and third-party parts: chlorine/pH/ORP/conductivity/turbidity/corrosion sensors, flow cells, peristaltic/pulse/centrifugal pumps, solenoids, water meters, brominators, calibration reagents, buffer solutions, and consumables. Manufacturer warranty is 36 months on controllers/circuit boards and 12 months on pumps and sensors.
2. AquaReporter subscription (SIM card and annual contract): Recurring revenue via the 'Web Access' bundle — a SIM card and annual contract for using the AquaReporter cloud web portal. Combined with 4G modem hardware (Modem 4G 850 / Modem 4G 900), this creates a hybrid hardware-plus-subscription model for ongoing remote monitoring services.
3. Professional services — custom configuration, consultancy, integration engineering: The company offers 'free consultancy' for water treatment projects and bespoke customisation of ULTIMA models ('Call Us To Customise Your Model'). Services include BMS/SCADA integration engineering (Modbus HLI, 4-20mA LLI), multi-tower system design, and compliance support.

Core offering

Aquarius Technologies designs, manufactures and supports the ULTIMA family of 7-inch touch-screen water treatment controllers, sold in industry-specific configurations for cooling towers, swimming pools, potable water, wastewater and post-harvest applications. The ULTIMA hardware integrates fuzzy-logic ORP/pH control, Accessory Timer / Inhibitor-Bleed Optimisation firmware and up to 13 outputs, paired with the AquaReporter cloud platform for 4G/Wi-Fi/Ethernet remote monitoring, Modbus BMS/SCADA integration, alarm notification and compliance reporting. The company also sells a complete ecosystem of branded and third-party sensors, dosing pumps, water meters, reagents, brominators and connectivity accessories to support end-to-end water treatment deployments.

Product overview

Aquarius Technologies offers a platform-plus-modules architecture centred on its ULTIMA 7-inch touch-screen water treatment controller. The ULTIMA is delivered in industry-specific firmware configurations — ULTIMA Cooling Tower, ULTIMA Swimming Pool (U-Series), ULTIMA Potable Water, ULTIMA Wastewater (Trade Waste / UTD) and ULTIMA Post-Harvest — each tailored to the chemical dosing, pH/ORP, FAC, conductivity and timer logic required by that sector. The companion cloud platform AquaReporter provides remote monitoring, control, alarming and compliance reporting across all ULTIMA sites via 4G modem, Wi-Fi or Ethernet, and integrates with BMS/SCADA systems through Modbus HLI or 4-20mA LLI. Surrounding the core controllers is a broad portfolio of accessories and consumables: Reiss and Aquarius-branded sensors and probes (chlorine, bromine, pH/ORP, turbidity, FCT, corrosion), calibration reagents and buffer solutions, peristaltic/pulse/centrifugal pumps (Aquarius AP Peri, Olimpia, Athena, Onga), BCD brominators, pulse water meters, tank alarms, SMC solenoids and CO2 regulators, plus BMS/Modbus PCB cards and connectivity bundles (4G modem, Wi-Fi, Ethernet, Web Access SIM).

• ProMinent: ProMinent is a global manufacturer of metering pumps, sensors and water treatment controllers (e.g., Dulcometer) for cooling, disinfection and process-water applications. It competes head-to-head with Aquarius ULTIMA across cooling-tower, potable and wastewater dosing and offers its own cloud monitoring, mirroring Aquarius' hardware-plus-software model.
• Hach (Danaher): Hach is a global leader in water-quality analysis instrumentation, sensors and controllers used across cooling towers, pools and drinking water. Its sc1000 controller and online water-analysis portfolio overlap materially with Aquarius ULTIMA's monitoring, dosing and BMS integration capabilities.
• Seko: Seko manufactures dosing pumps and integrated water-treatment control systems for swimming pools, cooling towers and industrial water treatment. It is directly comparable to Aquarius in selling controllers bundled with chemical dosing and remote monitoring for similar end markets.
• Walchem (Iwaki America): Walchem is one of the closest direct peers to Aquarius: it designs and manufactures water treatment controllers for cooling towers, boilers, potable water and process applications with comparable dosing, conductivity, pH/ORP and web-monitoring functionality. Both companies sell integrated controller-plus-software platforms to industrial and commercial water-treatment operators.

Regional players

• Kurita Water Industries: Kurita is a Japanese/APAC leader in industrial water treatment, including chemical dosing, controllers and digital water management for cooling towers and process water.
