I. Industry Positioning of High-Precision Chillers

In fields such as semiconductor chip manufacturing, precision optics, and high‑end laser processing, even the slightest fluctuations in process temperature can significantly impact chip yield and the output accuracy of optical systems. High‑precision chillers, as core process equipment that ensures process stability, are tasked with rapidly removing heat generated during equipment operation and chemical reactions by circulating coolant at a constant outlet temperature, thereby enabling precise control of load temperatures. Currently, the industry’s mainstream temperature‑control stability specification is approximately ±0.1°C; however, for cutting‑edge applications like lithography tools, semiconductor metrology equipment, and wafer bonding, this level of stability—±0.1°C—is no longer sufficient to meet performance requirements.

II. Jice High-Precision Chiller Product Lineup

Jice (Nanjing) Technology Co., Ltd., leveraging its extensive expertise in precision environmental control, has developed a comprehensive portfolio of high-precision chillers. Its chiller product line has been launched. Room-temperature compression type and Heat-exchange type Two major technological approaches cover a temperature range of 5°C to 35°C, with outlet‑water temperature stability as high as ±0.002°C (±2 mK).

Chiller with Ambient-Temperature Compression Refrigeration Equipped with a self-developed high-precision temperature-sensing module and control algorithm, the product line is divided into two major series: “High-Precision” and “Standard.” The High-Precision series is primarily designed for precision cooling of heat-generating components in semiconductor manufacturing equipment, laser systems, and optical inspection devices. The Standard series caters to industrial applications such as electroplating, plastic molding, and chemical processing, with cooling capacity, flow rate, and interface dimensions all customizable to meet specific requirements.

Heat-exchange chiller Using an external cold source as the energy carrier, heat exchange between the working fluid and the cold source is achieved via a high-efficiency heat exchanger. Paired with flow‑and‑temperature control systems, this solution is particularly well suited to production environments that already have centralized cooling infrastructure, balancing temperature‑control accuracy with operational energy efficiency.

III. Core Technological Advantages

1.  Millikelvin-level temperature control algorithm : A self-developed high-precision temperature-sensing module, combined with an adaptive control strategy, achieves outlet water temperature stability within ±0.002°C, improving temperature-control accuracy by an order of magnitude compared to the industry’s mainstream ±0.1°C.

2.  Customized non-standard solutions for all scenarios : With our own production base and 100% in-house control over critical processes, we offer flexible customization of key parameters—including cooling capacity, flow rate, pressure, interface dimensions, and cleanliness requirements—based on specific operating conditions, enabling integrated delivery that seamlessly aligns “precise demand identification, efficient solution implementation, and ongoing service assurance.”

3.  Comprehensive Security Protection : Standard features include overload protection, high- and low-pressure protection, liquid-level monitoring, leak detection, and self-diagnostic functionality, ensuring the equipment’s long-term reliability under continuous operating conditions.

IV. Typical Application Scenarios

The highly precise temperature control of the Jice High-Precision Chiller has been validated across multiple high-value applications:

●   Semiconductor manufacturing : Precision cooling of the process chambers in lithography tools, etching equipment, and thin-film deposition systems is critical to chip linewidth accuracy and batch yield.

●   Precision Optics : Cooling of lens modules in laser interferometers and optical measurement platforms to prevent measurement errors caused by thermal expansion.

●   Laser processing : Cooling of high-power laser cavities to maintain stable output power and beam quality.

●   Industrial manufacturing : In applications such as maintaining constant temperature in electroplating tanks and cooling injection molds, it ensures product consistency and production efficiency.

Currently, Jice has served numerous global leaders in the semiconductor, telecommunications equipment, and optoelectronics industries, as well as key national laboratories, with its products and technical solutions rigorously validated through demanding real-world applications.

V. Selection Recommendations

The core parameters for selection include: temperature control accuracy, temperature range, cooling capacity, flow and pressure regulation capabilities, safety protection rating, and flexibility for non-standard customization. One should adhere to “ Condition-first, precision matching, and expansion-ready design Principle:

●   Define the heat load : Determine the cooling capacity requirement based on the heat dissipation of the equipment to be cooled, thereby avoiding under‑sizing or oversizing that can lead to energy inefficiency.

●   Select the technical approach : In standalone operation scenarios, ambient‑temperature compression refrigeration is preferred; for factory environments already equipped with a centralized cooling source, heat‑exchanger‑based systems can be selected to reduce energy consumption.

●   Focus on temperature control accuracy and stability. : For semiconductor and optical applications, a high-precision model (±0.002°C) should be selected; for general industrial manufacturing, a standard model can be used, balancing performance and cost.

●   Assess Customization Requirements : If there are specific requirements regarding flow rate, pressure, interfaces, cleanliness, or other factors, priority should be given to suppliers with the capability to provide full‑range, non‑standard customizations.

●   Consideration of Operations and Maintenance Support : Verify that the equipment is equipped with self-diagnostic capabilities and comprehensive safety protection features, and assess the supplier’s after-sales response mechanism and on-site support capacity.

Jice has launched a technological push in the field of environmental control, which not only represents an evolution of technical performance metrics but also embodies the inevitable path toward “precision and controllability” in high-end manufacturing.
