Compact, integrated system

Xylem's Wedeco SMOevoPLUS ozone system combines maximum flexibility and reliable operating characteristics for small to medium ozone capacities. The ozone generator system and control unit can be combined and supplemented with option sets that allow for various application requirements. 

The SMOevoPLUS series is specially manufactured to operate with lower cooling water consumption,  solving up to 60% water with maximum energy efficiency resulting in very low lifecycle costs. The new SMOevo PLUS system suit every application.

Both the SMOevoPLUS ozone generator unit and power supply unit are mounted separately on a steel skid, considerably reducing the on-site installation footprint. In fact, the footprint is reduced by up to 20% as a result of the optimum arrangement of the generator vessel, pipework and electrical cabinets. 

The ozone generator vessel can also be arranged either upright or horizontally to suit local requirements, and is forklift-accessible from all sides, allowing for easy transportation and installation. 

The unit’s pipework is made entirely of stainless steel, providing flange fittings where necessary, and is equipped with monitoring and optional concentration measurement instruments. 

The power supply unit is equipped with state-of-the-art semiconductors technology (IGBTs) for improved system control. 

An air conditioning system eliminates the thermal power loss of the electrical components both ensuring protection class IP 54, and allowing for operation under ambient conditions with high temperatures (up to 35°C), high humidity (up to 90%), and harsh or dusty surroundings.

Maximize the ozone with Effizon evo 2G electrodes

Effizon evo 2G electrode technology is the core element of every Wedeco SMOevo ozone system. Featuring a glass core, which consists only of high strength borosilicate glass and stainless steel mesh, the Effizon evo 2G helps Wedeco ozone systems achieve a level of reliability and energy efficiency unattainable with most other electrode technologies.

The electrodes are manufactured completely from inert materials, without the need for fuses or coatings, making them highly resistant to corrosion. This means that the Wedeco ozone generators are practically maintenance free with no need for regular cleaning or replacement of the electrodes.

Effizon evo 2G electrodes offer multiple independently operated safety layers. This inherent safety feature is called Intelligent Electrode Protection. Intelligent Electrode Protection complements the existing active protection interlocks inside the power supply unit (PSU) with an additional passive electrode protection that does not rely on power. In contrast to traditional safety concepts, such as fuses, the innovative Intelligent Electrode Protection is not prone to any false detection in the event of electrode defects.

The unique dual gap of the Effizon evo 2G electrode guides the oxygen gas flows across this electrical field on both the inside and outside of the glass tube dielectric. Medium voltage with variable frequency control is connected and evenly distributed to all electrodes, connected at the stainless steel mesh, which is supported with a glass rod. The glass dielectric tube provides resistance needed for creation of an electrical field in each stainless steel tube. The result is efficient ozone production on both sides of the dielectric, lowering the applied specific energy and increasing ozone production.
