Each TC100 package comes with a submersible pump allowing you to connect multiple conicals to one chiller. Simply place each pump into the cold bath you are using for chilling and attach the hose going to you conical's coiling coil. The return tubes from each conical can re-fill the same bath. 

Usually, 3-4 conicals can be handled by the cooling capacity of a good glycol chiller. Success is if multiple conicals can be crashed at the same time, if that is not possible, think about another chiller
