Can I use the 200 mm and 300 mm Pilot Height Reduction kit with my 30 L or 35 L vessel? The 200mm Height Reduction Kit is compatible with both the 30L and 35L Reactor-Ready Pilot vessels. However, the 300mm Height Reduction Kit is not compatible with the 30L or 35L Reactor-Ready Pilot vessels. Please note, the 200mm Height Reduction kit is only compatible with the 30L and 35L vessels when used in combination with the new version of our Lower Support Plate. The plate stiffeners on the sides of the new version of the Lower Support Plate have now been shortened. Please see the images of the Lower Support Plate stiffener versions below: New shortened version of the Lower Support Plate stiffener: Old longer version of the Lower Support Plate stiffener: If you require the new version of the Lower Support Plate, please contact the Customer Service team at [email protected].
