Thankyou MintJulep

Dear all I faced 15hp two piston refrigeration compressor with failed unloader solenoid. It seams clear that when the unloader valve remain closed before motor startup, the starting current and torque remain high. And failed open before start up, perhaps no cooling. But I want know what will...

Dear all, I have been told that iron mesh with visible pore size is used to separate (keep apart) sodium and chlorine from contacting each other but allows both ions. But i want to know the mechanism it work

Thank you EdStainless currently I have done with alcohol as you said and seems fine. In case the volatility of the ethanol become problem then I may switch to antifree

Yes Compositepro that is another alternative but I need the chiller to be a little below water freezing whereas automobile freezing point is far below 0 degree centigrade. 10% ethanol solution has freezing point of -4 degree centigrade ( i think i can control the freezing point by varying the...

Thank you EdStainless. I will try alcohol(ethanol solution)

I am sorry to see the fast response lately due to internet connection problem. Anyways thank you EdStainless, alcohol is a good choice for me it is available. but if you mention some non chloride salt for me that would be nice and one last question could sugar serve the purpose of salt?

Dear all, I have refrigeration system where the evaporator is copper tube in a bath. Now I need to use salt-water solution to refrigerate another storage place a bit below 0 degree Celsius may be -1 degree Celsius. I am planning to immerse the copper evaporator in salt water and circulate this...

cause it seems purchasing it is expensive than building it at least in may country

ok 14ton is for A/C, so does the system seems feasible?

Dear itsmoked look i dont want the A/C compressor to make ice directly. what i want is let the A/C compressor chill a water say 5 degree celesius and another freezer compressor will make this water to ice i want the ice for drinking ice size 4-5cm and diam of 1cm 80-120 kg/24hr my...

so is there any limitation building water cooler with AC compressor? because AC compressor is more available to me

ok thankyou i got your point. but can i use air conditioner compressor for cooling/chilling water which then i feed to the ice maker and hence enhance production rate?

Dear all, I am building ice maker. I have passed many of the challenges I faced, but now is another challenge i am facing. And i will ask you if the solution that i am thinking might work the problem is:- i cant get compressor(hermetic piston type) with enough HP like 3-5Hp for ice making but...

Ok IRstuff now i know where to post this question thank you.

i thought electro-plating is under paint/COATINGS is n`t it?

Dear all happy new year is it possible to plate copper on lead say rod and melt out z lead and get copper tube?

my mechanism is as follow. A bath pivoted will align and pump start to fill the bath with water while the evaporator end (now the bare copper tubes) immersed in the bath. Then freezing cycle start and ends after about 30% of the bath water converted into ice on the surface of the copper tube...

Good. if the issue is only for ice sticking then i don't worry because there are many type of ice maker one of the type involve spraying of water on the stainless tube (I think this is the one that need more concern on ice sticking) the other type is immersing the stainless tubes in a bath of...

Dear all, I am building an ice machine with copper tubes which are chrome plated but i am afraid of the duration of the chrome plate (i have faced similar plating failure). So i want to know health risk associated with copper being used in wet situation without chrome plate. also i have...
