For each percent of water in the ammonia, you are losing about 2% in compressor capacity
Liquid in ammonia refrigeration plants:-Analyses have shown that the typical content of water in ammonia used in industrial refrigeration plants is about 1-6 %, in worst cases up to 10%.
Water in ammonia leads to amplified power consumption, oxidization and results in decomposing oil, which contaminates the plant. Water, dirt and oil residues are inevitable in the kinds of big industrial refrigeration plants where ammonia is often used. This causes many problems in the plant in general, and in the compressors in particular. This means that the standard maintenance intervals prescribed by System integrator are no longer sufficient and the over-all operating costs reach an unnecessary high.

• Water: Water causes the oil to decompose.
• Dirt: Dirt is deposited in filters, valves, temperature exchanger and pipe systems.
• Oil residue: Oil residue causes contamination, mostly in the case of evaporators and low- pressure vessels.

What is Advantages of Ammonia Dehydrator:

Lower Installation Cost:
Lower Installation Cost Because it requires only a simple level controller, solenoid valves and a few isolation valves, the Manik WDO keeps the cost of installation to a minimum.

Self Regulating Operating:
The unique design of Manik Anydrator allows it to operate continuously. It easily handles system upsets without reintroducing water and contaminants to the pump separator after they have been removed.

Shortest Payback Time:
Thanks to its low initial cost, the Manik Anhydrator pays for itself in least amount of time.

Energy-Neutral Operation:
Unlike many other system cleaners, the Anhydrator uses sensible heat from the high pressure liquid to separate the ammonia from water and other contaminants. Instead of being wasted, the resulting flash gas is now doing useful work: cleaning your system.

Very Low Maintenance:
Batch-type system cleaners must be monitored and drained at unpredictable intervals. Its self-regulating operation and ability to safely return ammonia to the pump separator make the Manik WDO virtually maintenance free. Start it up and let it run. Drain Water and contaminants at your convenience. The unit will hold the water and contaminants indefinity Reduced power consumption by the plant compressors Reduced wear and tear on compressors and valves Elimination of cumbersome oil draining A very clean plant Optimal performance of the refrigeration plant Reduced maintenance costs Less down time Improved operating cost

System Cleaner removes the Water, Dirt and Oil from Ammonia System that air purger leaves behind The MANIK WDO is the only system cleaner that boosts

• Lower Installation Cost
• Self Regulating Operating
• Shortest Payback Time
• Energy-Neutral Operation
• Very Low Maintenance

How you can tell if there's water in your system ?

Air-purgers only removes non-condensibles like air. If your air-purger has been venting air, it's been leaving behind the water vapour that's always in the air. If your recirculating evaporator is operating a few degrees warmer than the pressure indicates, this could be due to water in Ammonia. If water comes out of your oil pot before the oil, there is water in your system.

You can easily measure the concentration of Water in your system
with the graduated Ammonia Sampling Container.
