Bitzer Supports Low-Charge Ammonia Chiller

Bitzer support for low-charge ammonia chiller

German refrigeration compressor manufacturer Bitzer has announced its support for the development of a new low-charge ammonia chiller. The chiller, which is designed to use less ammonia refrigerant than traditional chillers, is expected to be more environmentally friendly and safer to operate.

Ammonia is a natural refrigerant that is widely used in industrial refrigeration applications. However, it is also a hazardous substance that can be harmful to human health and the environment. The new low-charge ammonia chiller is designed to reduce the amount of ammonia used by up to 75%, which will significantly reduce the risk of leaks and accidents.

Bitzer is providing its expertise in ammonia refrigeration technology to support the development of the new chiller. The company is also manufacturing key components for the chiller, including its compressors, oil separators, and valves.

The new low-charge ammonia chiller is expected to be available in the market in early 2024. It is expected to be a popular choice for a wide range of applications, including food processing, warehousing, and data centers.

Bitzer’s commitment to sustainability:

Bitzer is a leading manufacturer of refrigeration compressors and components. The company is committed to developing sustainable refrigeration solutions that reduce the environmental impact of the industry. Bitzer is a founding member of the Kigali Cooling Efficiency Program (KCEP), a global initiative to reduce greenhouse gas emissions from the refrigeration and air conditioning sector.

The development of the new low-charge ammonia chiller is a significant step forward in Bitzer’s commitment to sustainability. The chiller is expected to have a major impact on the refrigeration industry, helping to reduce the environmental impact of cooling and air conditioning systems.


Q: What is an ammonia chiller?

A: An ammonia chiller is a type of refrigeration system that uses ammonia as the refrigerant to absorb and remove heat from a space or process. Ammonia is a natural refrigerant with excellent thermodynamic properties, making it a highly efficient and environmentally friendly choice for large-scale cooling applications.

Q: How does an ammonia chiller work?

A: An ammonia chiller works based on the vapor-compression refrigeration cycle. The cycle involves four main components: a compressor, a condenser, an expansion valve, and an evaporator.

  1. Compressor: The compressor draws in low-pressure ammonia vapor and compresses it to a high pressure. This increases the temperature and pressure of the ammonia vapor.
  2. Condenser: The hot, high-pressure ammonia vapor is then passed through the condenser, where it releases its heat to the surrounding air or water. This causes the ammonia vapor to condense into a liquid.
  3. Expansion valve: The high-pressure ammonia liquid is then passed through an expansion valve, which reduces its pressure. This sudden drop in pressure causes a portion of the ammonia liquid to flash evaporate, creating a mixture of liquid and vapor.
  4. Evaporator: The low-pressure ammonia liquid and vapor mixture is then passed through the evaporator, where it absorbs heat from the space or process being cooled. The ammonia vaporizes completely, becoming a low-pressure gas. The cycle then begins again as the low-pressure ammonia vapor is drawn back into the compressor.

Q: What are the benefits of using an ammonia chiller?

A: Ammonia chillers offer several benefits over traditional refrigerants, including:

Q: What are the drawbacks of using an ammonia chiller?

A: The main drawbacks of ammonia chillers are:

Q: What are some of the applications of ammonia chillers?

A: Ammonia chillers are widely used in a variety of industrial and commercial applications, including:

Q: How much does an ammonia chiller cost?

A: The cost of an ammonia chiller will vary depending on the size of the chiller, the specific requirements of the application, and the cost of installation. Generally, ammonia chillers are more expensive than traditional chillers, but they can offer significant long-term savings due to their higher efficiency and lower maintenance costs.

Q: Are there any government incentives for ammonia chillers?

A: Yes, there are a number of government incentives available to encourage the use of ammonia chillers. These incentives can include tax credits, rebates, and grants.

Q: How can I find a qualified ammonia chiller installer?

A: It is important to find a qualified ammonia chiller installer to ensure that your system is installed properly and safely. You can ask for recommendations from friends, family, or your local refrigeration contractor. You can also check online resources to find qualified installers in your area.

Q: How can I maintain my ammonia chiller?

A: Proper maintenance is essential for ensuring the long-term performance and efficiency of your ammonia chiller. You should schedule regular maintenance with a qualified refrigeration technician. You can also take steps to maintain your ammonia chiller yourself, such as changing the filters regularly and keeping the area


The development of the new low-charge ammonia chiller is a positive development for the refrigeration industry. The chiller is expected to be more environmentally friendly and safer to operate than traditional chillers, and it is expected to have a major impact on the cooling and air conditioning sector. Bitzer’s support for the development of the chiller is a testament to the company’s commitment to sustainability.
