Introduction To PoU cooler module for pharma water system

Stand-by mode With continuous circulation in the module/subloop it is possible to avoid draining and thereby keeping the main distribution loop closed towards the environment. The module/subloop is kept sanitized. The design of pitot tube arrangement [1] ensures that the product is kept circulating in the point of use cooler even in stand-by mode. With continuous circulation in the heat exchanger it is possible to avoid draining and thereby keeping the water loop closed towards the environment. The sub loop is kept sanitized. The design of pitot tube arrangement [1] ensures that the WFI/PW is kept circulating in the module in stand-by mode. Figure 1 . Cooling mode In cooling mode the recirculation is stopped, cooling media is turned on and when the user point is opened WFI/PW is available within seconds. For cooling of water for injection in manual module (the module with manual point of use valve the following steps should be done:Turn the air switch on [2] from stand-by mode to cooling mode. The cooling water valve [4] will automatically will be open and the recirculation valve close [3].Open the point of use valve [5] carefully and cold water for injection is available within seconds.
