The heated trap works best the closer to the chamber. This ideal installation right after the turbo pump reduces the number of heaters needed when the trap is farther away from the pump exit. If the pumping system can accommodate an few extra liters of inert gas, the combination of the Virtual Wall and the heated trap will provide increased uptime and reduced maintenance time. If heaters are required, MKS has heaters that can run as high as 250°C if the line before the trap needs to be heated instead of another solution.
The heated trap can run at temperatures up to 450°C and the gas temperature leaving the trap will increase the pressure locally and a recommended distance of at least 1 meter to allow for gas cooling is recommended before the gas reaches the pump.
