Applus+ TST improves the capacity and versatility of its furnaces for testing high-temperature fans

The laboratory has invested in its facilities in order to provide testing and certification of high-temperature fans by way of offering steady temperatures of up to 600 ºC. Furthermore, it has acquired a second variable frequency drive of 400 V to increase the capacity of daily testing.

Applus+ TST, a leading testing laboratory for high-temperature fans, has made improvements to its facility upgrading the circuitry and isolation of its recirculation furnace with a view to broadening its testing capabilities and providing a more flexible service, tailored to manufacturer needs.

Temperatures of up to 600 ºC

Applus+ TST has also brought about a variety of improvements in the build and insulation of its recirculation furnace for large fans. The aim of these improvements was to raise the testing temperature to 600 ºC. Following the success of its initial tests, the laboratory has demonstrated its ability to provide tests at this temperature.

To date, the European standard EN 12101-3:2016 and the CE Marking only contemplate testing fans at temperatures of up to 400 ºC. However, there is a growing interest among manufacturers in testing at higher temperatures with a view to staying a step ahead of future regulatory changes that are already being observed in several European countries.

More start-up and power supply options

The laboratory has invested in a new 400 V variable frequency drive to supplement its 6900 V drive. This second drive broadens the start-up and power supply options to clients, allowing them to select the option that best fits their needs:

• ACS800-07-1500-7 + F260 + K458 + P920 variable frequency drive with NSIN 1380-6 filter. For engines up to 690 V 1000 A 1000 kW, suitable for tests of up to 6900 V by way of a voltage booster
• VSD3/RFT-150 frequency shifter. For 400 V 202 A – 110 kW engines
• 400 V – 250 A – 150 kW direct supply
• 690 V – 200 A – 200 kW direct supply
