Erwin Sander Elektroapparatebau GmbH products

The Sander Certizon range of ozonizers offer from 25 mg/h to 300 mg/h of ozone output. All Certizon ozonizers are equipped with an adjusting knob for easy regulation. The ozone element can be cleaned easily, if required. The light and compact design can be installed and operated on a bench or wall-mounted.

All model S ozonizers guarantee reliable ozone production at low energy consumption. The ozonizer S 500 has a maximum ozone output of 500 mg/h. The ceramic ozone electrode is reliable and can be cleaned easily, if required. A potentiometer (adjusting knob) allows an easy adjustment of the ozone output required for the individual application. The S 500 can be operated in fresh water as well as in marine water systems.

The ozonizer S 1000 has a maximum ozone output of 1000 mg/h. The high-quality components guarantee a reliable ozone production at low energy consumption. The ceramic ozone electrode is robust and can be cleaned easily, if required. A potentiometer (adjusting knob) allows an easy adjustment of the ozone output required for the individual application. The S 1000 has been designed for medium-size fresh and marine water aquaria and can be also be used in pond installations.

Rated up to 2000 mg/h of ozone output, the XT 2000 ozonizer model is unique in its line. Its high-quality components and processor-controlled ozone production design ensure reliable ozone output while keeping energy consumption to a minimum. The ozonizer is equipped with a large touch screen display for quick access and fine adjustments of all the operational parameters. The XT 2000 is a professional tool for the ambitious aquarist and is perfectly suited for fresh water, ponds and marine water applications.

Using the so-called counter current principle, Sander Protein Skimmer Model I (external) allow for an intensive skimming process and the removal of toxic protein compounds. The big reaction tube provides excellent oxygen enrichment of the aquarium water. The Protein Skimmer Model I (external) can be operated with a water pump (injector) or with an air pump and wooden air stones.

The Clean + Clear is a new compact water treatment system specially designed for base cabinets. The filter drawers are removable and very easy to use. The mechanical pre-filter chamber consists of three mat layers. Water distribution plates distribute the water flow evenly through the mat layers, and the biological trickle filter placed underneath. A clear water chamber is intended for the connection of a feed pump (provided by the customer). A protein skimmer with a venturi pump is operated in the partial flow. The protein skimmer can also be operated with ozone (on option).

Sander wooden air stones are made from lime wood (German natural product) and produce the finest air bubbles, even in fresh water. They work with only little pressure loss. The wooden air stones are available in four different sizes.

Sander’s Biological Trickling Filters are filled with filter media that is being sprinkled with water via a trickling tube. On the sprinkled filling material, a so-called bacteria bed grows up over time. Surplus material will be led out together with the sprinkling water. A constant gas exchange is one of the advantages of this trickling filter. This gas exchange grants a constant oxygen supply of the bacteria and on the other hand harmful gas as e.g., CO₂ and/or Nitrogen (N₂) are being emitted into the air. An additional ventilation is not required. Sander’s Biological Trickling Filters are suitable for applications in fresh and in seawater.
