Hydrovar HVL4.075-A0010 7,5kW 3x400V

Characteristics

Description

Hydrovar is a pump-mounted variable speed, microprocessor-based system controller, and was the world’s first of its type to manage motor speed and match pump performance to a range of hot and cold water applications. The biggest advantage is saving energy: the pump delivers exactly what is necessary at the moment, which can save energy up to 80%.

Basic funtions of Hydrovar:

• Regulating continuous pressure
  The desired pressure is set by the user. The Hydrovar adjusts the speed of the pump to the desired output and keeps the system pressure at its level.
• Regulating based on system curve
  The user can adjust the pressure in the system to compensate its resistance. The user can enter an increase in pressure in the system in a percentage at maximum speed and capacity, and when the system needs to start the compensation.
• Regulating based on constant capacity
  The user enters the desired capacity in the system. When the capacity varies, the Hydrovar adjusts the pressure to keep the capacity constant.

• Shut the pump off when there is no demand for capacity. De pomp uit schakelen als er geen capaciteit gevraagd wordt.
• Protect the pump against overcharging, overheating and above/under voltage peeks.
• Vary the speed during starting and ending (soft start technology)
• Correct a higher resistance in the system by higher capacities automatically.
• Display in different languages: Dutch, English, German, French, Spanish, Italian and Portuguese.
• Communicate with other hydrovars or compurters via RS 485 interface.
