High-Efficiency Condnesing Unit Product Series: Stable Cooling, Energy Saving & Wide Application

High-Efficiency condnesing unit series is engineered to deliver reliable and energy-efficient cooling for critical applications in cold chain logistics, food processing, retail supermarkets, biopharmaceuticals, and industrial refrigeration. Combining core international components, innovative design, and intelligent control, it is your ideal choice for energy savings and stable operation.


Low-Temperature Condensing Units

Specialized Refrigeration Design: Engineered for evaporator temperatures typically below -10°C (14°F), using robust compressors and components built to handle higher compression ratios. Features enhanced oil return systems and specialized refrigerants (like R404A/R448A) optimized for sub-freezing operation.

Robust Components: Incorporates heavy-duty valves, motors, and controls designed to withstand thermal stress and prevent frost damage during frequent defrost cycles common in sub-zero environments.


Product Features

1. International Brand Compressor, Reliable Core:

● Equipped with genuine, top-tier international brand compressors (Copeland, Danfoss, Tecumseh, Hitachi, Boyang [or other specified brands]).

● Designed for low vibration and high reliability, achieving an optimal balance between performance and long-term cost efficiency.


2. High-Efficiency Heat Exchange Design, Enhanced COP:

● Optimized system matching significantly improves the Coefficient of Performance (COP).

● Incorporates oversized condensers and a specialized subcooling design, resulting in a comprehensive refrigeration capacity increase of up to 6%.


3. Intelligent Oil Management System, Trouble-Free Operation:

● Features a high-efficiency oil separator, minimizing lubricant circulation loss.

● Advanced oil balance control ensures stable and reliable lubrication for the compressor across all operating conditions, extending core component lifespan.


4. Wide Temperature Range Adaptability, Versatile Application:

● Broad refrigeration operating range: -35℃ to +10℃ (-31°F to +50°F).

● Fully supports multiple operating modes: Medium Temperature (M), Low Temperature (L), and High Temperature (H). Offers flexibility without frequent equipment changes.


5. Condenser Fan Speed Control (FSC), Energy Saving & Noise Reduction:

● Energy Saving: Intelligently adjusts fan speed based on ambient temperature and system pressure, significantly reducing fan energy consumption.

● Efficiency Enhancement: Optimizes condensing airflow, boosting overall refrigeration system efficiency.

● Improved Environment: Reduces unit operating noise, minimizing impact on surrounding areas.

● Highly Efficient & Stable: Utilizes high-performance DC variable speed motors for efficient, stable fan operation.

● Intelligent Control: Sophisticated control system automatically adjusts fan speed for optimal system matching and enhanced energy efficiency.


6. Low Noise Operation, Environmentally Friendly:

● Optimized scroll or rotary compressor design combined with high-efficiency fans significantly reduces operating vibration and noise. Ideal for noise-sensitive environments like hospitals, laboratories, and residential areas.


7. Premium Components & Robust Craftsmanship, Durable Construction:

● Utilizes international brand core components, such as solenoid valves (SV) and filter-driers (F/D).

● Fully welded, heavy-duty framework ensures rigid structural stability and long life.

● Professional anti-corrosion painting process effectively resists harsh environments like salt spray and high humidity, enhancing durability.


8. Multiple Safety Protections, Reliable Operation:

● Comprehensive built-in safety protection features include: Discharge Overheat Protection (DOP), High/Low Pressure Protection (HPP/LPP), Motor Overload Protection (MOP). Monitors systems in real-time, effectively preventing faults, ensuring safe and reliable operation, and extending equipment life.


Application Areas

Critical Cold Storage Applications: Essential for deep freezing, industrial process cooling, and long-term frozen storage (-18°C to -30°C / 0°F to -22°F). Ensures reliable product preservation in freezers, blast chillers, and ice manufacturing.

● All types of Cold Stores (Freezing, Cold Storage, Fresh Keeping)

● Food Processing Plants & Cold Chain Logistics Centers

● Large Supermarkets & Convenience Stores

● Biopharmaceutical & Chemical Process Cooling

● Other facilities requiring stable, efficient refrigeration.
