Plymovent case study at EQIN training centre

New extraction system at training center

THE CHALLENGE

After many years of faithful service, the extraction system at the EQIN training center in Rotterdam was in need of replacement because it no longer met the current technical and legal requirements. EQIN places great importance on setting a good example for their students, and this includes of use of a good extraction system.

EQIN carefully examined all the options available in the market and compared solutions from a number of potential suppliers. Quality of the product and the proposed solution were the deciding factors that led them to once again choose Plymovent.

THE SOLUTION

The training center has 18 welding cabins. These welding cabins are used to work on small, flexible work pieces, making it possible to create permanent workstations equipped with source extraction. To give the students as much flexibility as possible within the welding cabins, the choice was made to equip each welding cabin with a T-Flex CW extraction arm.

The extraction arm is based on a telescopic tube with counterweight, which gives the arm a working radius of 2.5 m in the extended position. In the retracted position the range is 1.5 m. The arm is equipped with a spring balance that makes it possible to swing the arm from a vertical to a horizontal position in a single movement. The extraction arms are individually, fully automatically controlled with infrared sensors at the entrance of each welding cabin. It was a carefully considered decision to equip each extraction arm with its own automatic valve so that when the extraction arm is switched on the automatic valve opens and the fan speed increases. This gets the students in the habit of using the welding fume extraction system and also makes this process extremely energy efficient.

In addition to these welding cabins there are also ten detached workstations. Of these, two workstations are equipped with T-Flex extraction arms and the remaining eight each have an UltraFlex-4 extraction arm. These detached workstations are suitable for the larger work pieces that will not fit in the welding cabins. The UltaFlex-4 extraction arms, with a range of four meters, were chosen to further expand the possibilities for working on large projects.

All exhaust arms are connected to a stationary filter unit located outdoors, the MDB-24. The MultiDust® Bank filter is a modular filter system that can be configured based on the current needs and easily adapt as those needs change. This unit filters the air, and the filtered air is then recirculated. This will result in energy saving when combined with heat recovery from the warm air.
