Evaporative Chillers
The optimal refrigeration solution for energy saving and carbon reduction
Evaporative Chillers Overview
One evaporative chiller is divided into two sides. One side is used for 120℃ high temperature heating and drying. The other side is used for 25℃ cooling and heat capture. A waste liquid recovery system is constructed by the jacket tank, condenser, and negative pressure system for waste liquid recovery and sublimation temperature control. An evaporative chiller is a cooling system that combines evaporative cooling with a refrigeration cycle to achieve energy-efficient cooling. It is particularly effective in hot, dry climates where water evaporation can significantly enhance heat rejection.
Evaporative Chillers Characteristics
- The evaporative chiller achieves excellent energy efficiency by innovatively combining evaporative cooling and mechanical refrigeration technology. Its unique dual-effect cooling mechanism fully utilizes the huge latent heat of water evaporation, which improves the system energy efficiency ratio (COP) by 30%-50% compared with traditional air-cooled units. The intelligent variable frequency control system can dynamically adjust the compressor speed according to the actual load, and can still maintain excellent energy efficiency under partial load conditions. It is particularly suitable for industrial production lines that need to run continuously for 24 hours, significantly reducing operating costs for users.
- The evaporative chiller is designed for harsh industrial environments and uses military-grade anti-corrosion treatment technology. The key heat exchange components are made of 316L stainless steel or titanium alloy, which can withstand chemical corrosive gases. The innovative anti-scaling design and self-cleaning function ensure that it can still operate stably at full load in a high temperature environment of 45°C. The modular structure design makes maintenance more convenient, and the mean time between failures (MTBF) exceeds 50,000 hours, significantly reducing the user’s total cost of ownership.
- The evaporative chiller integrates the latest Industrial Internet of Things technology, and the equipment is equipped with an intelligent monitoring system. It can collect and analyze operating data in real time, and realize remote diagnosis and energy efficiency optimization through the cloud platform. The adaptive control algorithm can automatically adjust the operating mode according to environmental parameters, and intelligent load distribution can be achieved when multiple machines are connected in parallel. The predictive maintenance function analyzes the status of key components through AI, warns of potential failures in advance, and maximizes production continuity. The evaporative chiller is an ideal temperature control solution in the era of intelligent manufacturing.

Evaporative Chillers Advantages
- Low water consumption: Evaporative chillers show significant water-saving characteristics during operation. Their water consumption is significantly lower than other types of cooling equipment. This design not only helps to reduce operating costs, but also reduces dependence on water resources, thereby achieving a more environmentally friendly and sustainable cooling solution. By optimizing the combination of water circulation system and evaporation technology, evaporative chillers can minimize water consumption while maintaining efficient cooling performance, bringing you both economic and environmental benefits.
- Flexibility in applications: Evaporative chillers are extremely flexible in practical applications and can adapt to a variety of different scenarios and needs. Their flexible characteristics make evaporative chillers the preferred solution in many projects, providing you with more choices and convenience. In addition, their high efficiency and energy-saving and environmentally friendly characteristics further enhance their appeal in various application scenarios.
- Reduced carbon footprint: As an efficient refrigeration equipment, evaporative chillers can significantly reduce carbon footprint during operation. By using the evaporation effect of water to achieve cooling, this technology not only reduces the dependence on traditional compressor refrigeration, but also significantly reduces greenhouse gas emissions. Its design principle combines natural cooling with technological innovation, further improving energy efficiency and bringing a win-win effect to enterprises and the environment.
Evaporative Chillers Importance
The evaporative chiller adopts an advanced closed-loop water circulation system design. By optimizing the spray water distribution and efficient heat exchange, evaporative chillers can save 20%-40% of water compared with the traditional cooling tower. The system can be equipped with an intelligent water treatment module to achieve automatic purification and concentration rate control of circulating water. This greatly reduces the amount of sewage discharged. At the same time, the equipment supports a new generation of environmentally friendly refrigerants, with zero ozone depletion potential and significantly reduced global warming potential. This fully complies with the most stringent international environmental regulations.
Evaporative Chillers Applications
Pharmaceutical & chemical industry: In the pharmaceutical and chemical industry, evaporative chillers have become the core equipment of key production processes due to their high efficiency, energy saving and precise temperature control. Through the principle of evaporative cooling, this model can quickly reduce the water temperature to the low temperature range required by the process, meeting the stringent requirements of reactor cooling, crystallization process temperature control, etc.
In API production, evaporative chillers ensure that chemical reactions take place at a constant temperature, avoiding side reactions.
In the field of biopharmaceuticals, its stable low-temperature performance provides a reliable cooling source for equipment such as fermenters and freeze dryers. Compared with the traditional cooling tower + chiller system, the evaporative chiller can save more than 30% of water, which is particularly suitable for pharmaceutical parks with tight water resources.
Semiconductor: The semiconductor industry has extremely high requirements for the stability and cleanliness of the cooling system, and evaporative chillers show their unique advantages here. The equipment uses a closed-loop design to effectively prevent particles in the air from contaminating the cooling water, ensuring a pure environment for wafer manufacturing equipment. In the cooling of key equipment such as lithography machines and ion implanters, evaporative chillers can achieve precise temperature control of ±0.1°C to ensure process stability. Its unique “dry condition” operation mode can adapt to the constant temperature and humidity environment requirements of semiconductor factories, avoiding the water mist generated by traditional cooling towers affecting the humidity of the workshop.
New energy: The photovoltaic industry uses the large cooling capacity of evaporative chillers to provide cooling services for poly-silicon ingot furnaces, slicers and other equipment. Compared with traditional air cooling systems, the energy efficiency ratio of evaporative chillers can reach more than 5.0, which can reduce operating costs by more than 30% under long-term high-load conditions such as energy storage battery testing. In lithium battery manufacturing, evaporative chillers are used for precise cooling of electrode coaters and roller presses, controlling the temperature within ±1°C to ensure the consistency and yield of electrode materials.
