HE PWM Circulator Pump

HE25-6-130P-HE PWM-Circulator -Pump
HE25-6-130P-HE PWM-Circulator -Pump

Description

HE PWM circulators pumps are premium high-efficiency circulators of compact design, suitable for all HVAC applications, from boilers and heat pumps to Heat Interface Units (HIU) systems. It is controlled with all basic functions and also PWM function for remote control. The pump features AUTO function which automatically adjusts the pump to system demands for optimal comfort and the lowest energy consumption as well as simple commissioning. The motor is based on permanent-magnet and compact-rotor technology securing silent operation and low energy consumption.

Suitable for:

  • Commercial heating
  • Commercial hot water recirculation
  • Domestic hot water recirculation
  • Domestic heating
  • Industrial heating
  • Heat pumps
  • Boilers

Key Features

ⅠⅡⅢ

Constant speed mode

Three constant speed modes for constant flow applications

CP

Constant pressure mode

• The pump maintains constant pressure regardless of the flow
• The preferred operation mode for under floor heating and 2 string systems with low flow variation
• Constant pressure curves (low and high)

PP

Proportional pressure mode

• If the proportional pressure mode is selected, the differential pressure varies proportionally with the flow, i.e. higher flow means higher differential pressure
• Proportional pressure is the preferred choice for one-string systems with high flow variation
• Proportional pressure curve (high and low)

AUTO

Autoadapt mode

• The factory setting, AUTO, analyzes the heating system and automatically adjusts the pump setting to meet the heating requirement. The result is optimum comfort and a minimum of energy consumption.
• AUTO can be used in 80% of the heating systemv
