WITA® Delta HE 100

0,00

As a material, WITA® processes cataphoresis-coated armature castings and chromium-nickel steel. These proven materials guarantee high resistance and a versatile range of applications. All circulating pumps are supplied with heat insulation shells, seals, coupling plugs or permanently installed cables.

In an average household, 10 to 15% of the electricity consumption is caused by conventional standard pumps. Through the use of the WITA® high efficiency pumps the energy consumption can be compared to a conventional circulation pump. Approximately 80%.
The hydraulic power could be almost kept the same compared to standard pumps.

Special features / Product advantages

  • – Highest efficiency through EC permanent magnet motor technology
  • – From 5 Watt min. input
  • – One-touch menu navigation
  • – Pre-selectable control modes constant speed / variable differential pressure
  • – Anti-block function
  • – Integrated motor protection
  • – High start-up safety
  • – Simple pipe mounting through a practical key attachment

 

With this pump, eleven different performancecurves can be selected. In addition to the six characteristics which operate according to the proportional pressure method, five further can be selected with a constant characteristic curve. Through the switchable night reduction, the power consumption can be reduced once the system temperature has been lowered. The LCD display shows the current power consumption, the selected characteristic curve and the night reduction.
