EWO – High frequency internal vibrators with built-in converter
The "EWO" high frequency immersion vibrators are equipped with a small electronic frequency converter, integrated in the power cable. This makes them suitable for being connected directly to a single-phase power outlet (115 V, 230 V, 50/60 Hz).
The range of EWO concrete pokers is characterized by a high centrifugal force, constant speed and greater resistance to wear, which makes it suitable even for the most consistent types of concrete and for continuous use.
The shaft is supported by four bearings for working in harsh conditions.
The EWO immersion concrete pokers, equipped with an integrated converter, are the ideal solution if it is necessary to connect the vibrating poker directly to the 115/230 V mains. They do not need to be connected to a frequency converter. The vibrating needle of the EWO is able to reach 12,000 vpm, the electric cable is 10 meters long and the operating tube, flexible and internally reinforced, is 5 meters long.Applications
The high compaction capacity allows the rapid removal of air bubbles trapped in fresh concrete, without any segregation of the elements that make up the mass. The result is homogeneous concrete, durable and mechanically resistant, without cracks or cavities. The wide range available meets all needs in both the private and civil engineering sectors.
Recommended for compacting concrete in the construction, for example, of industrial floors, walls, pillars and floors.Features
The high centrifugal force is generated by a high frequency electric motor integrated in the vibrating needle.
EWO concrete pokers are equipped with a small polyamide control panel (IP 66 protection), with a switch designed to resist wear and protected by a reinforced seal.
The electronic converter, complete with switch, is integrated in the power cable and housed in a robust aluminum housing, with dust seal, waterproof (IP 66). It is protected against overload, overvoltage, excess temperatures and short circuits. A LED indicates correct operation or the presence of a fault through different colors that correspond to specific errors.
All electronic components are coated with resin to protect them from vibrations, humidity and knocks.
