I am purchasing a brominator for use with a evaporative condenser (cooling tower) and was wondering what is the difference between an on line brominator and an off line brominator?

An "In-line Bromo feeder is plumbed directly in the flow path of the plumbing. An offline feeder must be plumbed to a pressure T-off (usually 3/8") just after the pump and then flows into the feeder, back out to a return T-off AFTER the last component before returning to the body of water being treated. As an example, in a pool installation, you would bring the return line in after the heater, so that the bromo concentrate would not be flowing through the copper heat exchanger, but rather after the heat exchange, preventing damage to the heater. In the case of the IN-LINE, it would be installed AFTER the last component.

Goodman unit runs and at the a-coil there is a piston where your suction and liquid lines connect. On the liquid side the piston is cold but warm on the other side of piston. A/C unit will not cool.

That piston is the metering device. On the liquid line, before the metering device it is always warm (this is sub cooled, high pressure liquid), but should flash to low pressure, lower temperature vapor once it passes through the metering device. The suction and liquid line never connect together.The liquid line brings liquid from the condenser to the evaporator. The suction line brings super heated vapor from the evaporator to the compressor. Since the unit does run, I'd have to put a gauge on it,but if I had to guess, I'd guess you have high head pressure. Check for dirt or debris on the condenser, check for proper clearance of the condensing unit and check for operation and directional rotation of the condenser fan. This could also be the result of an over charge.

Conair mini split heat pump isn't cooling but has cold suction line but warm liquid line and is not freezing up the evaporator. Thinking a sucking reversing valve?? What could cause that? Both evapor

Make sure that your refrigerant charge is good first. Reversing valve has 4 pipes coming off of it. The one alone is discharge and centre of 3 is suction always. The two sides are the reversing pipes. One side should be same temp as discharge and other same temp (+-5F) as suction. If not then you have bypassing refrigerant in valve. Bad.

I have a wine chiller which is not refrigerating. The red light in the back is still lite but temperature is 60 degrees and should be 54. I purchased the product in 2007 and wondered if this is an easy fix...

There are many different causes behind machine not cooling. 1. Defrost can be the cause for your refrigerator notcooling problem. To check to see if you have a defrost problem, look in thefreezer to see if there is ice build up on the evaporator cover. (Theevaporator covers are either in the back of the freezer or on the bottom of thefreezer). 2. If the condenser fan (the one under refrigerator) is notworking, the compressor will cut off on the overload. If the evaporator fan isnot running, there will be no airflow to the machine. First walk up to therefrigerator and listen to see if the fans (one in the freezer on one under thebottom) are running. If one is running and the other is not then get to the onethat is not running and see if something is blocking it. If there is nothingblocking it then replace it. 3. Dirty condenser can be the cause for your refrigeratornot cooling problem. If the condenser is dirty, the compressor will cut off onthe overload. If theseparts working correctly, then probably the compressor itself is faulty. You needto replace it. Hope this will help you. Good Luck.

Unit not cooling down,compressor running,condenser fan running. suction line just cool,condenser line barely warm.

Check if evaporator fan is running. Is there any frost buildup on freezers evaporator cover? If so you have a defrost problem (bad heater, defrost thermostat, thermister, defrost timer or circuit board ). If no frost and the freezer is warm then you most likely have a sealed system problem(leak, restriction, bad compressor) which is costly to repair.

Refrigerator is not cooling

Dirty condenser, condenser fan or evaporator fan motor are not running, Ice build up on evaporator and restricted the air flow. If compressor, condenser fan and evaporator fan motor are running but not cooling, then either compressor or sealed system problem.

Hi Robert, I repair and install commercial refrigeration and may be of help to you. You need to determine the size of the evaporator coil so you can match up the condensing unit for it. I don't no the voltage that it is, but this makes no difference, just make sure the condensing unit is the same. The condensing unit comes as a package, compressor, defrost clock, everything you need. All you need to do is run your copper, suction, and discharge lines and electrical through the roof and tie in at the evaporator. Install your driers and site glass at roof on your liquid line going back to the compressor.Your new condensing unit will have your power lines out, marked for you to tie into. You will need to set a disconnect box at the condenser. I am not sure what this box has to run, evaporator fans and a thermostat. All other controls will be with condensing unit. Since you are setting this up simular to a walk-in box, if the box didn't come with a txv, ( Expansion valve) you will need the right one for the evaporator to match. A liquid line solenoid valve at the evaporator to start and pump down the unit when the stat is satisfied. It will be wired into the thermostat down below. When you go to the parts house take all of your model, serial, product numbers with you and cubic inches as well. They will fiqure out the size you will need and what you will need. Wiring is very easy doing what you are doing, but if you feel you need a diagram, ask them and they will come up with a drawing for you to work from. They are very helpful if you are getting this condensing unit from a refrigeration parts wholesale house. Thay will tell you exactly what you will need to split this box. I hope I haven't confused you. It is basically very easy, just take your time and you can do this. Best of luck,
