Is it True High corrosion on Aircon in Creeks?

[anthon05]

hi fellow tsikot member..

I'm having this issue for the past 10 yrs i think i have bought 5 units window aircon on my house.. repaired also

five of them.. i live around 200 meters from a creek, its a small creek around 5 to 6 meters wide, i think its connected to the pasig river.

the aircon tech told me that corrosion on the copper tubing and rust are common for houses near creeks or rivers.

is this true? anybody have experience? the usual problem with my aircon are leak on the copper tubing.

i'm considering buying the Condura Extreme. advertised as more durable to withstand rust and corrosion.

thanks

The salt (airborne salinity) or chemicals in the air and elevated moisture that's reeking off nearby bodies of water is one of the common cause of corrosion in A/C units.

Yes that might be the reason. i should make a survey for people or living near creeks or body of water how they solve this issue.

Swamp gas (hydrogen sulfide or h2s), even in minute amounts, can cause a lot of corrosion even in the best stainless steels. Sisiw lang ang copper tubing dyan. Pag naaamoy mo yung creek sa bahay mo then umaabot sa inyo yung gases na sumisingaw dun sa creek. Remember ang creek sa metro manila = open sewer, naku dami h2s nyan.

Condura xtreme has durakote to prevent the corrosion... Totoo po un na kapag malapit sa creek or aalm ko dagat, madali masira at kalawangin ang ac...

Likod ng bahay namin creek. Mga 10 meters lang away sa pinaka malapit na Window Type Aircon pero wala naman kami corrosion problem sa 4 aircon sa bahay.

Check mo yung air quality kung pasig river connected yan alam mo naman gano ka dami toxic waste ang nakaka lusot sa mga walang pakialam na pabrika dyan. Kung salt lang di naman masyado since yung mga unit na gamit ko dati sa sea shore mas mataas ang salt content ng hangin don tumatagal naman ang ac

Same here. Our house is less than 300 m away from a creek and we never had problems with our AC.

Well as i said if you can smell it then yes you have a problem. If there is no smell like rotten eggs then the creek emits no corrosive gases.

I stay on a small island and you can get to the beaches in less than fifteen minutes. My units lasts an average of seven years even though they are exposed to the elements. Ground your equipment properly. In country, a lot of these so called electricians are either lazy pwede na yan electricians or they don't know the importance of grounding. To extend my ac units life I protect the ferrous components with petroleum jelly brushed on to the vulnerable areas

Oh. There's no bad smell from the creek.

Kawawa houses near Manila bay at old Paranaque (near St Andrew's). Dumidikit sa ilong yung amoy.

Correction I think my house is less than 100 meters from the creek. inside the house i don't smell anything, but if i go out near the creek on summer, it smells bad.

i think i will try condura Extreme. advertised as more durable in 'corrosive areas'.


Thanks

from what i understand, corrosion is hastened in areas exposed to seawater vapor, and in areas with access to geothermals.

sir yebo tanong lang may tendency ba na sa swamp / creek pwedeng maka abot ng 12ppm? may certain point na ang H2S pag umabot sa mataas na PPM may tendency sya na hindi maamoy di ba?

The more na naamoy mo sya mas "safe" (basta pasok sa LEL), the more na hindi mo maamoy (since unang papatayin ng H2S eh yung pang amoy) mas delikado? CMIIW.

[yebo]

If i remember right nasa 100 ppm ang level at which the sense of smell does not detect both H2S and SO2. 700 ppm is fatal, 1000 ppm is instant death. The sense of smell can also be deadened at lower concentrations with prolonged exposure. For example you can still smell it at 50 ppm but after some time you will not smell it anymore.

Pwede umabot sa higher concentrations sa swamp, creek, etc depende sa source of the H2S. If raw sewage is being dumped into it then one can expect a lot of H2S being emitted. Combine that with poor ventilation and you have a recipe for an accident waiting to happen.
