MELAdem 53 at attractive prices

During water treatment, the MELAdem 53 ion exchange system takes positively charged or negatively charged ions from the raw water and exchanges them for ions of the same charge. Through ion exchange, practices and clinics achieve the desired water quality for the reprocessing of medical products. However, this gradually exhausts the synthetic resin present in the ion exchanger cartridge. Since our autoclaves and thermodisinfectors have an integrated conductivity measurement, the decreasing water quality sooner or later leads to a warning or malfunction message.

The subsequent professional regeneration is an environmentally conscious and resource-saving procedure. This is because after the mixed bed resin has been replaced, not only can the MELAdem 53 container be completely reused, but also used resin is reprocessed for future regenerations.

The capacity, i.e. how much demineralized water can be treated with the resin, depends particularly on the ion concentration in the input water and thus on the water quality. If the water has a high ion concentration or conductivity, more ions must be exchanged, which results in a shorter operating time of the MELAdem 53. With regard to conductivity and water hardness, the containers of the MELAdem 53 have a capacity of:

• 2800 liters at at 10 °dH

• 1200 liters at 20 °dH

• 800 liters at 25 °dH

When stored in a cool and dry place, the mixed bed resin cartridge can be used for up to 18 months (see marking disc). The optimum temperature range for storage is 2 - 20 °C. A mixed bed resin cartridge filled with water must always be protected from frost.

Some practices and clinics have a central water softening system for the water supply. A softening system removes the hardness-forming ions from the drinking water and exchanges them in equal part with sodium ions. The increased sodium content in the water can lead to a one-sided load on the ion exchanger system and thus to premature exhaustion of the MELAdem 53. Therefore, if your central softening system is connected to the water supply in the treatment room, please ensure the correct functioning of this system together with the manufacturer - for example, after regenerating the central softening system with sodium / salt, the first intermediate rinse should be fed directly into the wastewater. Please note that an upstream softening plant has no positive effect on the capacity of the MELAdem 53.

Using your regeneration code, you can request the regeneration of your MELAdem 53 cartridge via the online order form (on our website or via the link). Please enter your regeneration code and serial number carefully. Typing errors will result in error messages.

The MELAdem 53 is a mixed-bed resin cartridge for producing fully demineralised water (DE water) from tap water. During operation, the resin becomes saturated, meaning that after a certain period of time the cartridge can no longer be used. ‘Regeneration’ involves replacing the mixed-bed resin:

1. Your cartridge will be collected by a courier service.

2. It is emptied and refilled with new resin at MELAG.

3. You will then receive your regenerated (refilled) cartridge back.

Your MELAdem 53 or MELAdem 53 C may only be dispatched in the original reusable transport packaging (consisting of a cardboard box, transport securing devices and sealing caps). Cartridges that are packed differently or inadequately cannot, unfortunately, be processed and will be returned to the sender.

• First order: The transport packaging is free of charge.

• Subsequent orders: The packaging is charged for (prices shown on the order form).

If the reusable transport packaging shows significant wear and tear, the cardboard box will be replaced automatically as part of the regeneration process at no additional cost.

Procedure for ordering reusable transport packaging:

1. Once your order has been received, MELAG will first send you the reusable transport packaging.

2. When the reusable transport packaging is dispatched, a collection by GLS is automatically arranged.

3. The collection takes place separately from the delivery of the transport packaging and occurs approximately 5 to 7 working days after the reusable transport packaging has been dispatched.

If you encounter any problems, please contact: Email : regeneration@melag.de Telephone: 030 757911 805233

Please note the following points to ensure that the process runs smoothly: •

• Empty the cartridge as thoroughly as possible after use.

• Seal the connections (using the sealing caps).

• Close the vent screw.

• Remove all old dispatch labels from the reusable transport packaging to prevent incorrect consignment numbers from being scanned.

Depending on the order workload, the reconditioning process (from collection to return) may take around two to three weeks.

Over time, individual components of the MELAdem 53 may also be subject to wear and tear. In the event of malfunctions or problems, please contact the refurbishment team to arrange and order an additional inspection or repair.

Please ensure that your MELAdem 53 is properly prepared for dispatch, as described in detail in point 4.

Proper preparation prevents damage in transit, moisture leakage (from the MELAdem) and incorrect deliveries. Please note that any damage, delays or additional costs arising from inadequate preparation are the responsibility of the sender.
