Hapag Lloyd chooses electronic pump control from Colfax

Wednesday, April 8th, 2015 von admin

Hapag Lloyd will equip ships of the 13,200-TEU Hamburg Express class and other vessels with the CM-1000® pump control system. The CM-1000 system controls the flow rates of seawater cooling pumps based on the temperature of the fresh water and the current need for coolant. As a result, the amount of seawater pumped into the seawater cooler matches requirements, saving electrical power on board the ship.

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.

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.
