HYDROVAR เป็นผลิตภัณฑ์จากแบรนด์ปั๊มน้ำระดับโลก Xylem ที่พัฒนาอุปกรณ์ควบคุมอัจฉริยะกับปั๊มน้ำ สำหรับติดตั้งกับปั๊มน้ำทั้งปั๊มแนวนอน แนวตั้งหรือแนวดิ่ง เพื่อเพิ่มประสิทธิภาพการทำงานของมอเตอร์ปั๊ม ใช้ได้กับกำลังไฟ 1.5 ถึง 22kW และ IEC Motor ทั่วไป โดยสามารถปรับการระบายความร้อนให้เหมาะสมกับพัดลมของมอเตอร์ 

Variable speed drives.  HYDROVAR™

HYDROVAR™ – the intelligent and user friendly speed controller for pumps!

HYDROVAR™ is a pump or wall-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.

Due to the unique modular design the HYDROVAR™ unit can be mounted or retrofitted

to any existing centrifugal pump which has a standard IEC motor.

This is the long-awaited solution for high-level installations requiring failsafe systems with a superior range of features, while its modularity also provides a cost-effective solution for low-level, reduced feature demands.

The HYDROVAR™ needs no additional master control and enables virtually any configuration of pumps: up to 8 master drives or a mix of master and slave drives. The units are available in powers from 1,1 – 22 kW.

The HYDROVAR™does much more than just change the motor speed. It truly manages your pump performance to match a wide range of system conditions allowing energy savings up to 70%

(approved by TUEV Austria) *.

* Tests carried out by TUEV Austria (Austrian testing authority) on 5 March 2005 based on comparative tables and data on intake performance at identical flow.
