KSB: New variable speed system for HVAC applications

Monday, February 6th, 2017 von admin

Etaline pump with PumpDrive Eco

This year’s ISH trade fair in Frankfurt will see KSB present a new 230 V version of its motor-mounted PumpDrive Eco variable speed system. Available for motor ratings ranging from 0.12 to 1.1 kW, this new version has been specially tailored to the requirements of HVAC applications.

PumpDrive Eco features sensorless differential pressure control which comes preset for use with Etaline L. All key parameters relating to pump and motor data are also set at the factory. This reduces the time required for pump set commissioning.

Alongside wireless Bluetooth modules for permanent installation supplied optionally, Bluetooth couplers are now also available. These can be plugged onto the service interface of PumpDrive Eco from the outside. This arrangement improves usability by also allowing communication with systems that do not have their own BT interface. The myPumpDrive app enables users to communicate with the system and make settings via smartphone.

WEG: New frequency inverter for decentralised motor and wall installation

Wednesday, November 26th, 2014 von admin

WEG2110_Bild1The MW500 frequency inverter with decentralised design has been developed for space-saving solutions, such as directly motor mounted or adjacent to the motor on the wall. As a result, the need for lengthy cables and switch cabinets is eliminated. MW500 is robust with an IP66 protection rating. It can withstand high overloading of 150% for 60 seconds every 10 minutes, and operate in temperatures up to 40°C (wall installation) and 50°C (motor installation). With increased ruggedness compared to alternative technologies, it provides reliable operation over a long service life. The inverter is designed to operate asynchronous motors in the power range 0.75 to 7.5 kW, and is offered as three variants for a mains voltage of 380 to 400V (A: 1.1 to 1.5 kW, B: 2.2 – 4 kW and C: 5.5 – 7.5 kW), and for 200 to 240V, as variant A (0.75 to 1.1 kW). It is ideal for many pump applications.
