The advanced Monoblock Unit from Shanghai Heleng Refrigeration delivers compact, pre-charged, and integrated cooling technology. We engineer these systems specifically for modular cold rooms. Each unit combines the compressor, condenser, evaporator, and controller into one factory-tested housing. This true plug-and-play design eliminates complex field copper piping. It also minimizes refrigerant leak risks and cuts installation times to under 20 minutes.
We hermetically seal and pressure-test every unit at our Shanghai intelligent manufacturing base. This ensures you receive a robust refrigeration system ready for immediate startup. For commercial operators and cold chain distributors, this pre-configured equipment reduces labor overhead. It also maintains the highest standard of thermal reliability.
Selecting the right installation layout and cooling capacity is essential. It ensures optimal temperature consistency and energy efficiency. We offer versatile configurations tailored to fit your specific structural limits and load requirements. This allows for seamless integration with existing storage room layouts.
| Mounting Type | Capacity Range | Best Suited For | Key Utility Advantage |
|---|---|---|---|
| Wall-Mounted (Side-In) | 1HP to 5HP | Small to medium cold rooms with height limits | Saves overhead clearance and reduces panel stress |
| Ceiling-Mounted (Top-In) | 1HP to 5HP | High-density storage and warehouse spaces | Optimizes interior space with uniform downward airflow |
Our wall-mounted designs slide directly into pre-cut slots on polyurethane insulated panels. Food retailers, commercial kitchens, and laboratories highly favor this layout. It works best when ceiling space is occupied by electrical lines or ventilation. The exterior condenser placement allows easier service access while keeping the inside footprint remarkably clean.
For facilities maximizing floor-to-ceiling shelving, our ceiling-mounted solutions are the ideal choice. These systems sit flush with the ceiling panel. They discharge cool air straight down to eliminate warm zones. Lifting the evaporator out of the active workspace prevents forklift damage and maximizes storage volume.
To simplify your equipment selection, we mapped our standard horsepower configurations to recommended cold room volumes. Actual performance depends on target temperatures, ambient climate, and door opening frequencies.
| Capacity Rating (HP) | Recommended Cold Room Volume (m³) | Typical Temperature Range (°C) | Primary Commercial Applications |
|---|---|---|---|
| 1.0 HP | Up to 12 m³ | -5°C to +10°C / -18°C | Small retail backrooms, florists, modular display coolers |
| 2.0 HP | 12 to 20 m³ | -5°C to +10°C / -18°C | Restaurant prep areas, micro-breweries, dairy holding rooms |
| 3.0 HP | 20 to 35 m³ | -5°C to +10°C / -22°C | Biopharmaceutical storage, school cafeteria cold rooms |
| 5.0 HP | 35 to 55 m³ | -5°C to +10°C / -22°C | Large food logistics hubs, specialty chemical storage |
Energy cost control and environmental sustainability are vital factors for modern industrial facilities. Our R&D team utilizes advanced thermodynamic designs and high-efficiency electrical hardware. This approach delivers excellent coefficient of performance (COP) ratios across our entire product line.
By utilizing variable-speed DC inverter compressors and EC fans, our systems adapt dynamically to thermal loads. Unlike traditional fixed-speed equipment, inverter technology matches power output to the exact cooling demand. This continuous speed modulation reduces overall power draw by up to 30%. It also significantly lowers start-up current spikes. This low starting load makes our systems exceptionally compatible with off-grid and hybrid solar-powered cold rooms.
Traditional electric defrost heaters draw massive electricity and radiate excess heat into the refrigerated chamber. This causes unwanted temperature spikes. Our monoblock systems utilize an advanced reverse-cycle hot gas defrost method. We route high-temperature compressor discharge gas directly into the evaporator coil. This melts frost and ice from the inside out very quickly. This rapid defrost sequence maintains stable storage temperatures and saves significant operating costs.

A Monoblock Unit houses both the evaporator and condenser in one pre-assembled chassis. It requires no copper piping, vacuuming, or on-site gas charging. In contrast, a split system separates these components and demands professional field pipe connections.
Installation is incredibly fast. It typically takes under 20 to 30 minutes. Our team designed the unit to mount simply onto a pre-cut panel slot and plug into a power source.
Yes, smaller capacities from 1HP to 3HP run on standard single-phase power. Larger commercial sizes, such as our 5HP systems, generally require three-phase power to operate efficiently.
Yes, our advanced DC inverter systems are highly energy-efficient. They integrate perfectly with hybrid or off-grid solar-powered cold storage configurations. We can easily adapt them to renewable energy setups.
