Freeze-drying—technically known as lyophilisation, lyophilization, or cryodesiccation—is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. Freeze-drying works by freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase.
Freeze master 280 or Rothenburg rofrost 28??
Which is the better and why??
I have read that the clamps with bungee straps on the freeze master can get into awkward spots but what's the reliability like on both?

Hi is it possible to hold a vaccum with bungs and change a 3 port valve, and it is 3 openings and I believe you can only have 2 openings, if not does anyone have any other solutions without draining down, or any other tips.
Good morning all
A quick question where do you install the mag filter on an external boiler installation? I know ideally it should be on the boiler return at its lowest point before the boiler. I am just a bit concerned about freezing etc. As I don't want it installed in the loft either which...
Bit of a tricky one. The stop tap in pavement is very old and does nothing. Water co says 10 months to come out and replace!!! The stop tap inside the Victorian house is under an access panel in floor inside front door as the tap is in void under ground floor. The pipe from under garden is lead...
Honestly are they worth the money? I keep looking at them wondering if one will save me time. I always have a couple cans of freeze squirt on the van don't tend to use a great deal.
Has anyone got one and its it of much use
I have a 32mm condensate pipe sticking out the wall for a combi.
It comes out the wall about 1m from the ground. It then needs to turn left and travel 3m where it will join right at the bottom of a soil pipe through a strap on boss.
My question is - can I put the 3m bit (as long as it is...

I've had my Rothenberger eco pipe freezer kit for about 1 year now, it was 2nd-hand when I got it but had only been used a couple of times.
All was fine when I first got it & I've used it about 30-ish times since. With no real problems.
But I needed to freeze 2 15mm central...

I'm back with another question.
I'm going to repair a leaking 10mm heating pipe tomorrow. Water has rotted the plasterboard ceiling so will be accessing the pipe through the ceiling. It's a big system in a 5 bed house so don't really want to drain the system.
I can't decide whether to bung the...
