    Improving a Closed Loop Cooling System – Flow Regulation between 1L/min and 10L/min

    I see, some of the smaller ones don't. But I'll make sure there is some sort of protection. For the rest I think I have enough information now, thank you all.

    Improving a Closed Loop Cooling System – Flow Regulation between 1L/min and 10L/min

    Currently 3 way valve is just for temperature control, by bypassing part of the water from going to the PHE and mixing it down the line with the cooled water from the PHE. Currently there is an expansion vessel, but this only protects against thermal expansion (I think). I'd rather combine this...

    Improving a Closed Loop Cooling System – Flow Regulation between 1L/min and 10L/min

    I see, right now I'm looking at rotary vane pumps (Fluid-o-tech). And this looks like exactly what I need. Can combine this with a flow sensor and simple PID and think this will work exactly like I would want it to. Most centrifugal pumps are indeed very low head pressure at low rpm's and...

    Improving a Closed Loop Cooling System – Flow Regulation between 1L/min and 10L/min

    Can probably get away with a 5:1 turndown, we test watercooled projects here with this system and flow control is essential here. Right now the 3 way valve is being used to precisely control temperature given to what project is connected to the system/load. But not sure if a centrifugal pump...

    Designing a Cooling System with a Plate Heat Exchanger – Pump & Flow Control Advice Needed

    I rewrote my first post because after posting I couldnt find it. Turns out it has to be reviewed first, thats on me haha.

    Improving a Closed Loop Cooling System – Flow Regulation between 1L/min and 10L/min

    Sorry I worded this badly, current system is 3.5L/min and needs to change to max 10L/min. Currently using a centrifugal pump without control on the flow, only 3 modes on but since the pump is underpowered it doesn't reach the full 1-10L/min range I'm looking for.

    Improving a Closed Loop Cooling System – Flow Regulation between 1L/min and 10L/min

    Hello everyone, I’ve been tasked with improving an existing closed-loop cooling system, which currently includes a pump, expansion tank, 3-way valve, and a heat exchanger. The system uses potable water, which circulates through the heat exchanger to cool the closed-loop water before being...

    Designing a Cooling System with a Plate Heat Exchanger – Pump & Flow Control Advice Needed

    Hi everyone, I'm working on designing a cooling system for a small test lab using a plate heat exchanger (PHE) since we have access to cold water. The system needs to cool a black box that outputs up to 4 kW of heat into water. The pressure drop across the black box is: 0.2 bar at 7 L/min 0.5...
