Ammonia low-pressure receivers with ammonia pumps are key components of industrial refrigeration systems using ammonia as the refrigerant. Here's how they work and their advantages: 1. **Functionality:** Low-pressure receivers serve as storage vessels for excess liquid ammonia in the system. They are typically located downstream of the condenser and are designed to hold liquid ammonia during periods of low demand or when the system is shut down. 2. **Purpose of Pumps:** Ammonia pumps, also known as recirculation pumps, are often integrated into low-pressure receiver systems. These pumps ensure proper circulation of the liquid ammonia throughout the refrigeration system, maintaining consistent pressure and flow rates. 3. **Operation:** When the system detects a need for additional refrigerant, such as during startup or increased demand, the pump activates to circulate liquid ammonia from the low-pressure receiver to the evaporators or other components of the system. 4. **Advantages:** - **Optimized Performance:** Low-pressure receivers with pumps help optimize the performance of the refrigeration system by ensuring a steady supply of liquid ammonia to the evaporators, which enhances cooling efficiency. - **Capacity Management:** By storing excess liquid ammonia, low-pressure receivers with pumps enable the system to handle fluctuations in demand more effectively, ensuring consistent operation and preventing potential disruptions. - **Energy Efficiency:** Properly sized and operated pumps contribute to energy efficiency by minimizing pressure drops and ensuring the efficient circulation of liquid ammonia throughout the system. - **System Protection:** Low-pressure receivers serve as a buffer against sudden changes in demand or system conditions, helping to protect components such as compressors from damage due to liquid slugging or inadequate refrigerant supply. - **Safety:** By providing a storage reservoir for liquid ammonia, low-pressure receivers with pumps help manage and mitigate risks associated with overfilling or overpressurization of the system, enhancing overall safety. Overall, integrating low-pressure receivers with ammonia pumps into industrial refrigeration systems offers numerous benefits in terms of performance, efficiency, capacity management, system protection, and safety.

An ammonia air purger, also known as an ammonia purge unit, is a component of industrial refrigeration systems that use ammonia as the refrigerant. Its primary function is to remove non-condensable gases, such as air and moisture, from the refrigeration system to maintain optimal performance and efficiency. Here's how it works and its importance: 1. **Function:** The ammonia air purger is typically installed at the highest point in the refrigeration system, such as at the top of the condenser or receiver. Its function is to continuously remove non-condensable gases, primarily air and moisture, from the ammonia refrigerant. 2. **Operation:** The purging process involves periodically venting the non-condensable gases from the refrigeration system. This is achieved by using a combination of pressure differentials and mechanical devices, such as float-operated valves or automatic purger units, to separate the gases from the liquid ammonia. 3. **Importance:** - **Efficiency:** Non-condensable gases can accumulate in the refrigeration system over time, reducing its efficiency and cooling capacity. By removing these gases, the purger helps maintain optimal system performance and energy efficiency. - **Prevention of Corrosion and Contamination:** Moisture and air can lead to corrosion of system components and contamination of the ammonia refrigerant, which can degrade system performance and reliability. The purger helps mitigate these risks by continuously removing these gases from the system. - **Prevention of System Damage:** Accumulation of non-condensable gases can lead to issues such as decreased compressor efficiency, increased power consumption, and potential damage to system components. Regular purging helps prevent these problems and prolong the life of the refrigeration system. - **Safety:** Purging non-condensable gases reduces the risk of pressure build-up in the system, which can pose safety hazards such as equipment failure or leaks. 4. **Maintenance:** Proper maintenance of the ammonia air purger is essential to ensure its effectiveness and reliability. This includes regular inspection, cleaning, and testing of purger components to verify proper operation and identify any issues that may affect performance. In summary, the ammonia air purger plays a crucial role in maintaining the efficiency, reliability, and safety of industrial refrigeration systems by continuously removing non-condensable gases from the ammonia refrigerant.

This Ammonia Reflex Glass Level Gauge assembly are used to check level of ammonia in the pressure vessels (ammonia receiver storage tank) Can also be used for other pressure vessel applications in refrigeration plants.

We provide two types:

• Fixed Type- Old Type (The valves will be directly welded on the body)
• Screwed Type-New Type (the valves will be separate with screwed connections which have to manually done)
