RW 130/500/S SKUMMARE – HÖJD 68 CM – TVÅ PUMPAR

RW130 S internal skimmers have been designed for obtaining more powerful skimming compared with the standard RW130.

The biggest difference between RW130 and RW130 S skimmers is that by RW130 S skimmers the water flow through the skimmer can be fully regulated, without being directly connected to the power of the air production pump like in RW130 series. A second pump, whose water flow can be regulated, according to the required skimming capability, provides the water circulation through the skimmer.

Therefore the contact time between water and air inside the contact chamber can be changed as required (skimming capability of any skimmer is in direct relation to the contact time inside the skimmer between water and air).

FEATURES

  • Body diameter: 130 mm
  • Double chamber (internal Ø 60 mm )
    The adoption of the double chamber allows to fully eliminate the inconvenience of air bubbles in the discharged water.
  • Can be completely disassembled
    RW skimmers can be completely disassembled, for periodical complete cleaning, thanks to the silicon connectors.
  • Foam collecting cup with cone-shaped discharge tube
    The cone-shaped discharge tube of foam collecting cup greatly makes easier the foam going up.
  • Telescopic adjustment of internal water level
    RW skimmers are provided with a special connector placed on discharge tube. Thanks to this device, the discharge tube becomes telescopic and the water internal level of the skimmer can be easily adjusted just only lifting up the discharge unit. In this way, the water level inside the skimmer will never change, even if the water level in the sump lowers due evaporation, because the water outlet is not restricted by a check valve or similar, and water is discharged by natural overflow.
    When the discharge unit is completely let down, there will be a dry foam production . By lifting up the discharge unit it is possible to get a more liquid foam.
    This system also eliminates the risk of total water filling of the foam cup in case the skimmer starts again after a power failure (this matter is particularly dangerous in case of protracted absence).
  • Air production pumps with ceramic shaft and ceramic bushing.
    The new pumps RIO plus are equipped with ceramic shaft and the needle wheel impellers are provided with ceramic bushings.
    The use of ceramic bushings totally eliminates the inconvenience of an excessive wear and tear of the impeller, due the abrasive action of the ceramic shaft when in direct contact with the plastic of the impeller (ovaling of the impeller’s seat of the ceramic shaft). This problem normally causes an anomalous rotation of the impeller, also increasing the noise.
    In case of heavy ovaling, this trouble can even prevent the starting again of the impeller when the pump is stopped for maintenance or due a power failure.
  • Venturi’s air tubing is connected to the foam cup’s cover (silencer)
    Thanks to this system, the noise of sucked air is totally eliminated.
  • Circulation pump with check valve
    RW skimmers 130 S are already provided with a circulation pump with check valve: it is possible to decrease the water flow through the skimmer, increasing the contact-time between air and water and therefore increasing the foaming performance of the skimmer
