Integrated Direct Expansion Refrigeration Units for Cold Storage & Industrial Applications

Home > Chiller Equipment > Refrigeration Unit

What Is a Refrigeration Unit?

A refrigeration unit is a complete direct expansion (DX) refrigeration package that integrates the condensing unit, evaporator, control system, and refrigerant circuit into a coordinated system. Unlike a standalone condensing unit, a refrigeration unit is designed to deliver ready-to-connect cooling performance for cold rooms, freezer rooms, and industrial refrigeration applications.

Refrigeration units are widely used where fast installation, system compatibility, and stable temperature control are required.

Refrigeration Unit vs Condensing Unit (Key Difference)

👉 A refrigeration unit delivers cooling as a system, while a condensing unit is part of a custom-built refrigeration setup.

Key Components of a Refrigeration Unit

A standard industrial refrigeration unit includes:

• Compressor (scroll, semi-hermetic, or screw)

• Condenser (air-cooled or water-cooled)

• Evaporator unit (ceiling-mounted or wall-mounted)

• Expansion valve

• Electrical control panel

• Safety and protection devices

Each component is engineered and matched to ensure system stability and efficiency.

Refrigeration Unit by Compressor Type

Scroll Refrigeration Units

Scroll-based refrigeration units are commonly used in small to medium cold rooms.

Features:

• Compact size

• Low operating noise

• High efficiency under stable loads

• Reduced installation time

Typical applications:

• Walk-in coolers

• Fresh food storage

• Beverage and dairy refrigeration

Semi-Hermetic & Screw Refrigeration Units

For larger systems, semi-hermetic reciprocating or screw compressors are applied.

Features:

• High reliability for continuous operation

• Strong adaptability to varying load conditions

• Suitable for medium and low-temperature ranges

Typical applications:

• Industrial cold storage

• Freezer rooms

• Food processing and logistics centers

Packaged vs Split Refrigeration Units

Packaged Refrigeration Units

All major components are factory-assembled and tested.

Advantages:

• Minimal on-site installation

• Reduced commissioning time

• Lower risk of system mismatch

Applications:

• Modular cold rooms

• Export projects

• Rapid-deployment refrigeration solutions

Split-Type Refrigeration Units

Compressor/condenser and evaporator are separated.

Advantages:

• Flexible layout design

• Lower indoor noise

• Suitable for large cold rooms

Applications:

• Custom cold storage projects

• Industrial refrigeration plants

Condenser Types in Refrigeration Units

Air-Cooled Refrigeration Units

• Easy installation

• No water consumption

• Suitable for most cold room applications

Water-Cooled Refrigeration Units

• Higher heat exchange efficiency

• Stable operation under high ambient temperatures

• Used in large or centralized refrigeration systems

Refrigerant Options

Refrigeration units can be configured with different refrigerants depending on application and regional regulations:

• R404A / R507

• R448A / R449A

• Other low-GWP alternatives available upon request

Frequently Asked Questions (FAQ)

Is a refrigeration unit the same as a condensing unit?

No. A refrigeration unit is a complete DX refrigeration system, while a condensing unit includes only the compressor and condenser.

Can refrigeration units be used for freezer rooms?

Yes. Refrigeration units can be designed for medium, low, or freezer temperature ranges based on compressor and refrigerant selection.

Are refrigeration units suitable for outdoor installation?

Packaged refrigeration units and enclosed condenser sections are suitable for outdoor installation.

Do you support custom configurations?

Yes. Refrigeration units can be customized for cooling capacity, temperature range, voltage, refrigerant, and branding.
