Model PTU-3 Pump and Tank Unit is designed for use with Physitemp's range of thermoelectric cooling and heating stages. It provides a convenient reservoir of cooling water when a stage is operated in the cooling mode for an extended period of time in a location which has no source of tap water nearby to cool the hot side of the thermoelectric heat pump. The reservoir tank holds five gallons of water, which is will adequately run the TS-4 series Thermal Microscope Stage for up to eight hours.

Water is circulated using a quiet 1/25 horsepower single phase motor and magnetically driven pump - so there are no rotating seals to leak or replace. Self sealing connectors are used on the inlet and outlet water connections to prevent spillage. Ice cubes may be added to the tank in order to extend the operating time or reduce the lowest temperature to which a thermoelectric stage can cool. A switched accessory outlet on the rear of all thermoelectric controllers is used to power the pump so water starts flowing immediately when the controller is turned on.
