Bridge thermostats 30 to 300 °C for temperature control thermostating of any bath
The LAUDA Proline bridge thermostats with vario flex pump are great for temperature control thermostating of any bath vessel. The PB models have a pressure/suction pump, but the PBD models are equipped with stronger pressure pumps. They enable temperature control thermostating on deeper baths of up to 320 mm.
A telescoping rod for baths with a width of 310 to 550 mm, an ergonomic handle and side pump connections are also available.
