HLT Feed To Wash Down Hose?

[Block 15]

Is anyone out there using their HLT to feed wash down hoses? If so, how are you achieving pressure to your hoses? Our new system will have an oversized HLT with recirculating instantaneous water heater and I would like to use this instead of installing another water heater.

thanks,

Nick,

We put a tee between our hot liquor pump and the grist hydrator and stuck a wash down hose on it. Be sure to spend good money on the hose in order to handle heat and pressure; ours was about $500 for a twenty-five footer.

Yeah. Our HLT pump is a 1.5 horse. The 1" pipe coming out of it splits off and one side runs up to the brewdeck mixing station and then the hydrator, brewdeck hose, and mash tun spray ball. On the other end a 1" pipe runs over to a second mixing station on the wall down by the tanks, which then splits to a valve with a 1.5" triclamp fitting on one side, and valve with a second hose on the other. The HLT pump runs the whole shebang, so you just have to be a bit careful using hot during mash in and sparging. It's pretty handy having a wall-mounted hot water triclamp right where you need it!

One might think that the orange "high temp" garden hose you can get at the hardware store would work fine. One would be wrong. And discover this the first time the end with the sprayer on it shoots off. Spend the cash and get a decent heat-resistant food grade washdown hose with a good sprayer.

You can use a pump to supply hot water for the entire plant from the HLT.
Most associated piping is 1 inch with a 1/2 inch bypass leg.
The pump is on a motor starter and is started for the work day and shut down at night.
On the subject of mixing stations, its a good idea to use check valves on both lines.
If hot and cold valves are open at the same time you can typically migrate hot into the cold line very quickly.
This can cause very quick problems with other building systems.
We are using a Goulds 1ST1G5A4 for this duty.

I follow you for the most part but just wanted to clarify. The piping coming out of the pump is 1 inch ID? And what purpose is the 1/2 inch bypass leg serving?

Are you guys using a pressure switch that will turn the pump off once a valve or spray nozzle is switched off?

Hi. Old thread here, but just seeing how people were controlling pressure on this? Is there a pressure switch and VFD?
