The LNEYA fluid chiller is designed for a wide range of applications where chilled water or liquid needs to circulate through process equipment. Like most temperature control systems, the chiller first fills with a set volume of fluid, which is then cooled by the internal chiller system. A pump circulates the chilled fluid to the target equipment, absorbing heat and lowering its temperature. The warmed fluid then returns to the chiller, where the cycle repeats—
effectively transferring heat away from the process using recirculated coolant.

If LNEYA standard industrial chillers do not meet your application, we can tailor a suitable solution
Air-cooled refrigerated circulatorsr: uses air to dissipate the heat generated by the condenser. Suitable for small laboratories or environments with limited water supply.
It eliminates the need for cooling towers, cooling water pumps and piping systems required for the cooling water system, avoiding problems such as condenser scaling and water pipe blockage in areas with poor water quality, while also saving water resources.
Water-cooled  refrigerated circulators: uses water to cool the condenser. Suitable for large laboratories or applications that require higher cooling capacity.
 
Difference:
The one-time investment of air-cooled water chillers is slightly higher than that of water-cooled chillers, but the annual operating cost is lower than that of water-cooled chillers, the construction cost of the machine room is less than that of various air-conditioning cold and heat source systems, and the maintenance cost is about 10% or half of that of boilers.

Coolants play a vital role in any chiller system, as they transfer heat away from the equipment, ensuring safe and efficient operation. LNEYA fluid chillers typically use the following coolants:

  • Water

Water is a common and cost-effective coolant, praised for its high thermal conductivity and ease of use. However, it’s unsuitable for very low-temperature applications, and high mineral content in water can lead to corrosion or clogging of pipes.

  • Oil

Oil chillers are ideal for high-temperature or extreme low-temperature scenarios where water would evaporate or freeze. While effective, oil is more expensive and requires more frequent maintenance.

  • Ethylene Glycol

Ethylene glycol is one of the most commonly used coolants in LNEYA chillers. The Glycol Chiller lowers the freezing point of water, allowing the system to operate below 0°C without the risk of freezing damage. Ethylene glycol usually mixed with water to form a glycol-water solution.
