1. Introduction of Ammonia in Metal replacement
Improve the adhesion of the metal surface;
Improve the corrosion resistance of metal surfaces;
Improve the hardness and wear characteristics of metals.
2. Advantages of R717 Refrigeration System Ammonia
1> Energy efficiency - Typically a flooded ammonia system would be 15-20 % more efficient than a DX R404A counterpart.
2> Environment - it has both GWP (Global Warming Potential) and ODP (Ozone Depletion Potential) equal to zero
3> Safety - At the same time, unlike most other refrigerants, it has a characteristic odor that can be detected by humans even at very low concentrations.
4> Smaller pipe sizes - In both vapor and liquid phase ammonia requires smaller pipe diameters than most chemical refrigerants.
5> Better heat transfer - Ammonia has better heat transfer properties than most of the chemical refrigerants and therefore allow for the use of equipment with a smaller heat transfer area.
6> Refrigerant price - In many countries the cost of ammonia (per kg) is considerably lower than the cost of HFCs. This advantage is even multiplied by the fact that ammonia has a lower density in the liquid phase. Furthermore as any leakage of ammonia will be detected very quickly due to the odour, hence any potential loss of refrigerant will also be lower.
3. Applications for Refrigeration System Ammonia
Refrigeration System Ammonia has a strong toxicity and flammability. If the volume meter, when the content of ammonia in the air reaches 0.5% ~ 0.6%, in which people stay for half an hour can be poisoning, 11% ~ 13% can ignite, reaches 16% flame would explode. Therefore, the ammonia refrigeration machine room must pay attention to ventilation and exhaust, and the air and other non-condensable gases in the system must be eliminated frequently.
5. Quality control (impurity gas and heavy metals)
Water vapor is the most important impurities in ammonia refrigeration system. It not only corrodes the refrigeration system but also changes the vapor pressure of the refrigeration system, making the refrigeration system less efficient. Other impurities such as oil, hydrocarbons, H20, 02, Ar, N2, H2, CO and CO2 will also affect the refrigeration system.
Our factory to produce Refrigeration System Ammonia introduced advanced EGPS Ammonia purification system. It will mainly pressurized ammonia into activated carbon filter, the main impurity removing oil and organic gases, then into the solid particles in the dust filter to remove ammonia, and then into the electric heating carburetor to ensure the operation of the system with constant pressure, then into the low boiling point in the ammonia distillation tower to remove ammonia gas, then through the relief into the oxygen in the dryer to remove ammonia trace water, finally enter the buffer tank storage for users.

3> Why choose our Refrigeration System Ammonia ?
Ammonia has a certain degree of harm to the human body, but we cannot ignore its great effect. First of all, let's understand the nature of high-purity ammonia in detail. High-purity ammonia is a colorless, toxic, alkaline, and highly corrosive combustible gas with a pungent odor. The high concentration is irritating to eyes, skin and mucous membranes. The density of ammonia gas is lower than that of air, and its density under standard conditions is 0.7081g/L. Ammonia is very soluble in water. At room temperature and pressure, 700 volumes of ammonia can be dissolved in one volume of water. The saturated vapor pressure of liquid ammonia at 21.1°C is 7.78 kgf/cm2. It is filled with 40L steel cylinder, 43LDOT steel cylinder Y tank or tank truck. High-purity ammonia is mainly used in the field of new optoelectronic materials and is an important basic material for the preparation of GAN by MOCVD technology. The production of high-sensitivity blue light emitting diodes and blue lasers by GAN, as well as other related electronic devices, is an industry that is seized at home and abroad. High-purity ammonia is also the basic material for preparing nitrogen trifluoride, silicon nitride, and the raw material gas for producing super high-grade nitrogen. In addition, liquid ammonia is widely used in the semiconductor industry, metallurgical industry, and other industries and scientific research that require a protective atmosphere.
4> What are the Advantages of Refrigeration System AmmoniaR 717?
1> Zero ozone depletion potential
2> Zero global warming potential
3> Excellent thermodynamic properties leading to a high energy efficiency
4> Wide range of operating temperatures (–50 to +15°C)
5> Low cost than others
6> More than 100 years track record of providing efficient refrigeration
5> What are the effect of purity and water vapor on the cooling system?
Water present in Ammonia systems creates a number of problems, including internal system corrosion and creation of sludge that can cause blockages in the systems. The presence of moisture impacts the vapor pressure of the system. This combined with corrosion and sludge, substantially impacts the efficiency of your system – with a notable deterioration even at levels of just 0.5%.
Other impurities such as O2, N2, and hydrocarbons will have a similar impact, increasing the risk of corrosion, stress corrosion cracking and system performance drops.
6> Can you accept OEM order and other services?
Yes, we can. OEM orders are available.Provide filling service, cylinder packaging water pressure testing and cleaning services.
