The HK control system provides NCS series functionality with the added protection of an enclosure as well as temperature compensation through internal heating and regulation. This series encloses the entire control system with only externals components being the plenums and nitrogen cylinders. Our stands provide the ability to affix plenums or nitrogen cylinders. Other customer requested options can be integrated into this control system.With the plenum bottles still likely being exposed to the elements, we would recommend investing in our Temperature Control Accessories to minimize pressure compensation within the system.
