Orben at GET Nord 2026: Mobile Water Treatment Units with Simplified Ion-Exchange Resin Replacement

Orben is presenting at the GET Nord trade show (Hamburg, 19–21 November 2026) its range of mobile water treatment systems for heating systems: THERMOSTIL mobil 5000, 6000, and 7000. The plug-and-play kits operate in bypass mode and house all components in a compact mobile enclosure: water treatment, filtration, circulation, and monitoring.

Quick-Refill Technology

The key innovation is the integration of the cartridge inlet, outlet, and rinse arrow directly into the 23-litre cartridge housing. Spent ion-exchange resin can be rinsed with fresh water without a separate rinse nozzle. After rinsing, the cartridge is refilled with THERMION 2035 pH conform ion-exchange resin. For convenience, an enlarged loading hatch and four separate 5.8-litre bags are provided. The optimised connection prevents incorrect cartridge installation.

Technical Specifications by Model

• THERMOSTIL mobil 5000 — for small and medium installations: throughput in bypass mode ≈ 700 l/h; during filtration ≈ 1,200 l/h.
• THERMOSTIL mobil 6000 and 7000 — for medium and large installations: throughput in bypass mode ≈ 2,400 l/h; during treatment and filtration — up to 1,800 l/h; during full desalination — up to 700 l/h.

Digital Measuring Unit (Model 7000)

The THERMOSTIL mobil 7000 variant is equipped with a digital measuring computer that continuously records flow rate and conductivity. A backlit display shows current values and the total volume of treated water; the system issues a warning when values deviate from set thresholds. Power supply: three AAA batteries.

Water treatment for heating systems is performed in accordance with VDI 2035 and DIN EN 14336.
