VacuumFurnaces.com is a Q&A community where vacuum furnace product and service suppliers connect with commercial and captive heat treaters to share their practical skills and know-how and to establish valuable relationships around niche topics of expertise with vacuum furnace end-users in operations, production, training, maintenance, marketing, sales, and engineering.
What type of water treatment do you recommend for a closed-loop cooling system?
Every closed-loop cooling system needs a modest amount of chemical treatment. Most are used once and then checked yearly. We recommend a sodium nitrite-based inhibitor with biocide to prevent biological contamination. This treatment is usually done at a 1% concentration so not much is needed. TheseRead more
Every closed-loop cooling system needs a modest amount of chemical treatment. Most are used once and then checked yearly. We recommend a sodium nitrite-based inhibitor with biocide to prevent biological contamination. This treatment is usually done at a 1% concentration so not much is needed. These inhibitors will protect both the ferrous and non-ferrous materials in your piping system. Many treatment chemicals come with a colorant which allows the treatment to be visually monitored.

ETHYLENE GLYCOL (EG)Is the green liquid we used to have in our car radiators. It’s the least expensive, hurts heat transfer the least, and hurts pump performance the least. It is toxic so its falling out of general usage. It is very corrosive so a suitable inhibitor package must be used to protect yRead more
ETHYLENE GLYCOL (EG)
Is the green liquid we used to have in our car radiators. It’s the least expensive, hurts heat transfer the least, and hurts pump performance the least. It is toxic so its falling out of general usage. It is very corrosive so a suitable inhibitor package must be used to protect your piping and equipment. Never use ethylene glycol for corrosion protection! Its only use is to prevent slushing and freezing of your coolant.
PROPYLENE GLYCOL (PG)
It’s the pink liquid we currently have in our car radiators. It’s about 20% higher in cost than EG, hurts heat transfer due to its high viscosity, hurts pump performance due to its high viscosity, and is needed in slightly higher concentrations than EG for equal freezing protection. Its winning appeal is its low toxicity. It is corrosive so a suitable inhibitor package must be used to protect your piping and equipment. Never use propylene glycol for corrosion protection! Its only use is to prevent slushing and freezing of your coolant.
DO NOT USE AUTOMOTIVE ANTI-FREEZE. Coolants for automobiles have inhibitors based on aluminum. Their inhibitor package is wrong for our industrial cooling systems.

See lessWhat are common leaks usually found in the vacuum chamber?
Any pass-thru (penetration) is typical or common. Pass-thru's with heat are even more suspect, as heating and cooling cause movement of materials. Threaded fitting are notorious as thread lubricants (pipe dope) dry out over time. O-rings become flat due to heat/time and they can become dirty.

See lessWhat gases does a halide leak detector sense?
Chlorine based refrigerant gasses. Gasses drawn in through a probe hose are exposed to a flame heated copper reactor plate. If chlorine is present the flame changes color. Phosgene (poisonous) gas can be produced using halide leak detectors. Be very careful.

See lessWhat is the difference between a leak and a seep?
I don't believe these are real technical terms with definitive differences. My opinion is that a leak could be defined as gas and seep could be defined as liquid.
