A counter-flow prevention valve is disposed within a body of a pilot-type channel valve. While electrical power is applied to a solenoid coil and the pilot-type channel valve is opened, i.e., while a gas is flowing through the counter-flow prevention valve and the gas is expanding, heat generated by the application of electrical power to the solenoid coil is conducted via the body and is effectively transferred to the counter-flow prevention valve. Therefore, even if the gas contains water vapor and even if this gas is cooled due to significant expansion, the water vapor can be prevented from freezing within the counter-flow prevention valve. Moreover, the volume of the pipe between the pilot-type channel valve and the counter-flow prevention valve is small, thereby resulting in a fast rise in pressure within the pipe and a quick opening of the counter-flow prevention valve, which provides an excellent valve-opening response.

The invention relates to a device (1) for freezing, transporting and thawing fluids, in particular sterile liquids, solutions and suspensions for the chemical, biotechnology, pharmaceutical and food industries. Said device comprises a container (10) with a lid (20), a wall (40) and a base (30) and at least one heat exchanger element (50) that is operatively connected to the fluids held in the container, such that said fluids can be cooled or heated. An immersion pipe (60) is operatively connected to at least one heat exchanger element (50) via at least one sub-region of its longitudinal extension, said region preferably extending approximately from a lowest point in the container to a maximum fill level. Preferably, the immersion pipe is in direct contact with at least one heat exchanger element and can be passively heated.
