A good hydraulic balance is highly important for HVAC and process systems with separated circuits or several groups and pumps. The effective removal of air and dirt also contributes towards the achievement of optimum system performance. Hydraulic balancing and air and dirt separation are combined in the SpiroCross. Thanks to the combination of 3 functions in 1, savings will not only be made in purchasing but also on installation and maintenance costs. The SpiroCross can be used for both new build, refurb and projects for refurbish heating, cooling and process systems. SpiroCross was developed by Spirotech using Computational Fluid Dynamics and was also tested extensively on our own TÜV-certified test and measurement set-up and various systems in practice.
