Air-Cooled High and Low Temperature Integrated Machine Circulating Heating and Cooling Equipment Overview
Core Abstract (核心摘要) The GDW Series Air-Cooled High and Low Temperature Integrated Machine is an advanced closed-loop thermodynamic system designed to provide highly precise, continuous heating and cooling circulation. Extensively utilized in the pharmaceutical, chemical, biological, and material science industries, it excels in regulating the temperature of jacketed glass reactors, rotary evaporators, and analytical instruments. Its core advantages include an ultra-wide operating temperature range (from -80°C up to 200°C), an intelligent fuzzy PID adaptive controller ensuring ±1°C precision, and premium imported compressors (Panasonic/Tecumseh). By seamlessly integrating both heating and refrigeration capabilities into a single unit, it ensures rapid, stable thermal transitions for highly sensitive material processing.
I. Product Overview & Core Advantages (产品概述与核心优势)
The GDW Series integrates high-temperature heating and ultra-low temperature cooling into one highly efficient circulating system. It eliminates the need for swapping between separate hot and cold baths, drastically improving laboratory and pilot-scale production efficiency. Its core advantages include:
- Intelligent Fuzzy PID Control: Features an advanced adaptive PID controller with a 3.5-inch LCD display, ensuring smooth, highly accurate temperature regulation (±1°C precision) with rapid response to thermal changes.
- Fully Enclosed Circulation System: The heat transfer fluid circulates in a completely sealed loop. This prevents oil mist generation at high temperatures, minimizes fluid oxidation, and prevents ambient moisture absorption at low temperatures, greatly extending the lifespan of the thermal fluid.
- Premium Component Integration: Equipped with dual PT100 temperature sensors for real-time inlet and outlet monitoring, alongside world-renowned compressors (Panasonic or Tecumseh) ensuring powerful, stable, and continuous cooling capacity.
- Ultra-Wide Temperature Range: Depending on the specific model, the system can smoothly transition materials from as low as -80°C all the way up to 200°C, making it an incredibly versatile thermal management solution.

III. Packaging & Shipping Information (采购包装与物流须知)
For international procurement and shipping, we provide secure and reliable delivery guarantees:
- MOQ & Robust Packaging: The minimum order quantity (MOQ) is 1 set. The equipment is heavily protected and packaged in a sturdy wooden case to withstand shock and vibration during international sea or air freight.
- After-Sales Warranty Policy: The main electrical and thermodynamic components come with a one-year warranty. During this period, we provide free replacement parts or remote maintenance services for any non-human damages under normal operation (freight costs from China to the destination are borne by the customer). We offer continuous lifetime technical support beyond the warranty period.
IV. Frequently Asked Questions (FAQ)
Q: Why choose an integrated heating and cooling machine over separate hot and cold baths? A: An integrated system uses a single closed-loop circulation path, allowing you to rapidly heat or cool a jacketed reactor without disconnecting hoses or exposing the thermal fluid to the atmosphere. This drastically saves time, prevents fluid contamination, and allows for automated, precise thermal profiling during complex chemical reactions.
Q: How does the fully closed circulation system benefit the thermal fluid? A: Because the system is sealed from the outside environment, the heat transfer fluid will not absorb moisture at sub-zero temperatures (which could freeze and damage the system) and will not oxidize or emit dangerous oil mists at 200°C. This greatly extends the life of the fluid and maintains a safer, cleaner laboratory environment.
Q: What type of temperature controller is used, and how accurate is it? A: The machine is equipped with an advanced Fuzzy PID adaptive controller paired with dual PT100 sensors that monitor both inlet and outlet temperatures. This setup prevents temperature overshoot and maintains a strict control accuracy of ±1°C throughout the entire thermal process.
