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.

Mitsubishi: IP55 variant added to inverter series

Wednesday, November 26th, 2014 von admin

8-1_Mitsubishi_SPS2014_FR-A846_Next_GenerationMitsubishi Electric has added dust and splash-proof versions with an IP55 protection rating to its FR-A800 series of frequency inverters. Specially designed for harsh environments and tailored to the requirements of pumps, the drives are highly robust and ideally suited for use in industrial and commercial building automation systems as well as in heating, ventilation and air-conditioning systems.  The new FR-A846 series with an IP55 protection rating represents Mitsubishi Electric’s latest drive technology in the output range from 400 watts up to 160 kW. The drive’s EMC filter built in as standard ensures full compliance with the EMC Directive (EN 61800-3, 1st environment, category C2) while its DC reactor – also built in as standard – ensures full compliance with IEC 61000-3-12 for reducing and limiting harmonic currents so that separate certification is not required. The FR-A846 also has a built-in main switch version with locking option.

WEG: New permanent-magnet motor surpasses IE4 standard

Thursday, April 10th, 2014 von admin

WEG2177_Bild1WEG has launched a permanent-magnet motor that fulfils this demanding requirement, making it one of the first to qualify for the IE5 Ultra Premium Motor designation.  With losses roughly 20 % lower than Super Premium models, it is among the first Ultra Premium motors on the market that fulfil the present criteria for the potential IE5 energy efficiency class. This makes the W22 permanent-magnet motor one of the most efficient electric motors currently available world-wide.

Siemens introduces new cabinet inverter for pumps

Wednesday, October 9th, 2013 von admin

IDT2013104098-01_300dpiWith the Sinamics G120P Cabinet, Siemens Drive Technologies Division is now able to provide an inverter cabinet unit especially adapted to pumps, fans, and compressors. The power spectrum of the existing Sinamics G120P series is thus extended to 200 kW. In line with the Integrated Drive Systems strategy, the drive is optimally adapted to operation with Simotics severe-duty and flexible-duty motors. For example, the inverter output currents have been adapted to the motor rated currents and the motors to the rated pulse frequencies of the inverters. Because the components interact as an integrated drive system, the voltage is optimally utilized and the noise level of the motor is also reduced by 4 dB. The efficiency of the overall system is 98 percent. The new inverter also has application-specific functions that enable economical operation of pumps.
