Each model has a rugged splash proof case, with all submerged parts being made from stainless steel or high temperature engineering plastic. Powerful pressure circulation pumps with external circulation connections are fitted as standard on all models (excluding the TU-20HT).

Inlet and outlet pipes at the rear of the controller can be used for external circulation to control the temperature of other apparatus or sealed for circulation within the bath itself. (excluding the TU-20HT).
