The Castel filter driers for HC are available with solder connections. They are 100% molecular sieve blocks. The construction of the filter driers is shock-resistant and the block shape is such that the refrigerant flow distributes optimally over the block. This gives the filter drier the highest drying efficiency and the least pressure loss.
These HC Castel filter driers are suitable for all HC refrigerants such as propane R290 and isobutane R600a.
