Heater Chillers
Temperature control range is from -120℃ to +350℃.
LNEYA SUNDI series circulation heater chillers can provide temperature control accuracy of heat transfer medium and reaction materials.
Heater Chillers Overview
A heater chiller is an integrated temperature control system designed to heat and cool fluids to maintain a consistent temperature within a process or piece of equipment. This dual-function device is ideal for applications that require rapid temperature changes or need to maintain a stable temperature range, such as in reactors, fermenters, test chambers, or laser systems.
✅ Temperature control range: -120°C to +350°C
✅ Temperature control accuracy up to ±0.3°C
✅ Ultra-high temperature cooling technology enables direct cooling from temperatures above +300°C
✅ Suitable for constant temperature control needs in most industries
Heater Chillers Characteristics

- Wide temperature control range: -120℃~+350℃
- High-precision temperature control accuracy: When used in conjunction with a reactor, LNEYA heater chillers can not only control the temperature of the heat-conducting medium, but also control the temperature of the reaction materials in the reactor. The temperature control accuracy of the heat transfer medium is ±0.5°C. The temperature control accuracy of the reaction material is ±1°C.
- Ultra-high temperature cooling technology: LNEYA heater chillers can directly cool from high temperature +300℃.
- Long Lifespan of Heat Transfer Medium: The fully enclosed circulation system ensures that high temperatures do not cause medium evaporation, and low temperatures do not absorb moisture from the air, resulting in a longer service life of the heat transfer medium.
- Remote Monitoring and Control: Certain models offer remote access, allowing real-time monitoring and control via computer or mobile devices.
- Safety and Reliability: Built-in multi-functional alarm system and safety features further ensure production safety.

Heater Chillers Advantages
- High efficiency and energy saving: heater chillers usually use advanced heat energy conversion technology, which can achieve efficient heating or cooling effects with less energy consumption. This not only saves energy costs, but also reduces the impact on the environment.
- Safety and reliability: Since it involves high and low temperature operations, the safety and reliability of the equipment are crucial. Most heater chillers provide a series of safety protection measures, such as overload protection, temperature control and other functions to ensure the personal safety of users and the service life of the equipment.
- Versatility: The integrated design allows these machines to perform heating and cooling operations at the same time, meeting the needs of different experiments. In addition, many modern heater chillers are also equipped with other functions, such as vacuum pumps, stirrers, etc., which further enhance their practical value.
- Strong customizability: According to different application scenarios and usage requirements, heater chillers can be configured and adjusted accordingly. This means that users can choose the right model according to their needs to meet specific experimental conditions and workflows.

Heater Chillers Importance
Temperature control: During the heating process, the equipment and process need to be kept within a specific temperature range. The heater chiller can effectively control the temperature, prevent overheating or overcooling, and ensure work quality and product stability.
Heat discharge: The heat generated during the heating process needs to be discharged in time, otherwise it will cause the equipment to overheat or even damage. The heater chiller removes the heat by circulating coolant or cooling medium to keep the equipment and process running normally.
Safety: The high temperature environment during the heating process may be dangerous to operators and equipment. The cooling and heating system can effectively reduce the temperature and reduce potential safety risks.

Heater Chillers Applications
Pharmaceutical industry:
- LNEYA heater chillers are widely used in pharmaceutical reactors for precise temperature regulation during API synthesis and intermediate reactions. In these processes, even slight temperature fluctuations can affect yield and product purity. Reactor cooling systems ensure fast temperature ramping, stable holding temperatures, and safe thermal control. These systems are often paired with jacketed glass or stainless steel reactors, meeting GMP requirements for data traceability and process consistency.
Chemical industry: - In the fine chemical and specialty chemical industries, reactors are frequently used for exothermic or endothermic reactions such as esterification, polymerization, and hydrogenation. LNEYA heater chillers enable dynamic temperature control across a wide temperature range, such as -40°C to +200°C. The reactor cooling systems help prevent thermal runaway and allow for programmable temperature profiles, increasing both safety and productivity.
Laboratory and pilot plant testing: - In laboratory-scale or pilot-scale operations, flexibility and precision are critical. LNEYA heater chillers support multi-step temperature programming, quick switching between heating and cooling, and compatibility with various reactor volumes. This makes them ideal for process optimization, new material R&D, and reaction condition testing.
New energy and battery materials: - Reactors used in the synthesis of lithium battery materials and electrolyte formulations often require precise thermal cycling. LNEYA heater chillers provide accurate, programmable thermal profiles for pilot plants and production lines. This ensures consistent product quality, especially in processes where material properties are sensitive to temperature variation.
