Product Features Efficient capacity adjustment: Digital vortex technology controls the combination and separation of vortex discs through electromagnetic valves, achieving stepless capacity adjustment from 10% to 100%, with extremely high partial load efficiency. Simplified system design: No need for complex variable frequency drive boards, high reliability, and minimal harmonic interference to the power grid. Soft start: When starting, it is in an unloaded state, with low starting current and minimal impact on the power grid. High energy efficiency: It can maintain a high energy efficiency ratio throughout the entire operating range, especially with significant advantages at partial loads. High reliability: The vortex structure operates smoothly, has fewer wear parts, and has a long lifespan.

I. Core Technological Advantages for Superior Performance1. Digital Scroll Technology
Core Advantage:This is the most significant feature of the ZPDT series. It utilizes "axial compliance" technology and a solenoid valve to achieve seamless capacity modulation (from 10% to 100%) through cyclical loading and unloading (referred to as "cycling").
Precise Temperature Control:Capacity can be smoothly adjusted between 10% and 100%, eliminating the frequent starts and stops of traditional fixed-speed compressors. This results in minimal temperature fluctuations within cold storage rooms or display cases, significantly enhancing the preservation quality and storage safety of goods like food and pharmaceuticals.
High Energy Efficiency Ratio (EER/COP):During part-load operation (i.e., not running at full capacity), the digital scroll compressor's EER/COP is much higher than that of fixed-speed compressors. Since equipment operates at part-load most of the time, its seasonal or integrated energy efficiency is exceptionally high, leading to substantial electricity cost savings.
2. Wide Operating Range
The ZPDT12M is designed for medium and low-temperature applications (such as freezing and refrigeration) and can operate stably at low evaporation temperatures and high ambient temperatures. This makes it highly suitable for:
Supermarket freezer/refrigerator display cases
Small walk-in cold storage rooms (Coolers/Freezers)
Kitchen cold chain equipment
This broad operating range provides excellent application flexibility.
3. High Reliability and Durability
Copeland Scroll Core Technology:The scroll compressor itself has a simple structure with few moving parts (only one rotating motion), far fewer than piston compressors. This translates to lower failure rates, reduced vibration, and quieter operation.
Built-in Protection Features:Includes protection against liquid slugging, better handling potential refrigerant migration or minor liquid floodback in the system, thus safeguarding the compressor from damage.
Robust Design:Specifically engineered for demanding commercial applications, ensuring a long service life.
II. Practical Benefits for the System and End-User1. Energy Saving and Reduced Electricity Costs
As mentioned, the digital capacity modulation technology allows the compressor to operate at peak efficiency most of the time, avoiding the high inrush current during full-load startup and inefficient operating ranges, resulting in outstanding overall energy efficiency.
2. Excellent Temperature Control
For applications requiring precise temperature control (e.g., high-end ice cream cabinets, biological specimen storage), minimal temperature fluctuation is a critical selling point.
3. Rapid Pulldown
After loading goods when the temperature in a cold room rises, the compressor can operate at 100% capacity to quickly bring the temperature back to the set point.
4. Simplified System Design
Since the compressor itself can modulate capacity, it can reduce or eliminate the need for external complex unloading devices (such as cylinder unloading, hot gas bypass valves) in certain applications, leading to a simpler system design.
5. Good Compatibility
Compatible with common medium and low-temperature refrigerants such as R404A, R448A, R449A, including environmentally friendly refrigerants, meeting future environmental regulations.
III. Summary The advantages of the COPELAND ZPDT12M compressorcan be summarized as follows: Centered around advanced "Digital Scroll" technology, it achieves precise temperature control, extremely high operating efficiency, and outstanding reliability.
