Crossflow vs Coil
The crossflow condenser was designed specifically as a recirculation closed loop solution for areas where coolant water is either expensive or in short supply. Recirc systems must have low friction and low pressure pumps with low power consumption else pumps become expensive and have shortened lives (impeller cavitation). However there are other significant advantages with crossflow condensers.
Resistance to coolant flow
Pumping power requirements
low (23 watt), low pressure
High (+250 watt), high pressure pumps or mains pressure municipal feed
Phase change (condensing) capability
Highly efficient. Designed for large steam volumes
Compact 2" x 6" horizontal
Large 2" x 12" vertical
Overall still height
Fiddly, requires some skill
Relatively easy (some will disagree)
Minimal loss, recirculated, 6 litres/minute, 20°C IN - 25°C OUT
Total loss, to waste or may be recirculated. 300ml/minute, 20°C IN - 70°C OUT
- I found that there was a very small amount of play in the "T" piece
that allowed me to do it so I didn't have to bend anything.

fitting slightly up? I thought of that, but couldn't think of a good
way, especially without throwing them out of round. I also didn't
really feel like messing around with it too much, that fitting cost me
more than my column!
