Balder is a 2½” monitor for use in connection with fixedinstallations; Balder is fitted with a 4” flange (DN 100).The pipes are casted in bronze. Parts which are vital for the correct functions, such as swivels are in stainless steel. Innovative piping technology minimizes turbulence and frictional pressure losses. The swivels are constructed to have an optimized function in environments with a lot of vibrations e.g. onboard ships.
