Technical Specifications
The document provides detailed specifications for the Serie M water demineralizers, which are designed to produce high-quality demineralized water. The models range from M4 to M50, with varying delivery rates and dimensions. The maximum pressure for most models is 5 bar, except for M4, which is 1.5 bar. The purity of the produced water is better than 0.5 µS/cm.

Application Fields
The Serie M demineralizers are suitable for various applications, including home dialysis, hospitals, research laboratories, aquariums, battery maintenance, fresco restoration, laboratory autoclaves, and industries such as galvanic, electronic, cosmetic, and chemical.

Maintenance
The Serie M demineralizers are designed for ease of use and cost-effectiveness. They offer two methods for resin recharge: replacing the resin charge or the entire column. Used resins and columns can be sent for regeneration, and M4 uses a disposable cartridge.

Versions and Spare Parts
There are six capacities available in three versions: without a conductivity meter, with a two-led conductivity meter, and with a digital conductivity meter (not available for M4). An intelligent code system helps identify models and spare parts.

Construction
The demineralizers are constructed from non-toxic polypropylene, resistant to pressures up to 10 bar (1.5 bar for M4). They contain high-capacity cationic and anionic resins. Two types of conductivity meters are available: a two-led meter and a digital meter. All versions include a kit of pressure-resistant connections and pipes with a sampling valve.

Examples of Codes
Examples of product codes include M0904 for a demineralizer M9 with a two-led conductivity meter, M3006 for a demineralizer M30 with a digital conductivity meter, and M5001 for a spare column for M50.
