Refrigerant Compatibility

This unit cooler supports a wide range of refrigerants, including HFC, NH₃, CO₂, Glycol, Water, and Brine, ensuring seamless integration with diverse industrial refrigeration systems. Its flexible refrigerant compatibility eliminates limitations, making it adaptable to both traditional and eco-friendly cooling setups.

Material & Construction

Crafted with high-quality materials, the CMD series offers multiple options to suit specific needs: it is available as a titanium air cooler for corrosion-resistant performance, a Stainless Steel air cooler (304/316) for hygiene-critical applications, and a cubic air cooler with AlMg fins for enhanced heat transfer efficiency. The fins feature thicknesses ranging from 0.15mm to 0.4mm, with fin distances customizable to 10, 12, 16-8, 18-9, 20-10mm or as per requirements. The casing and water tray are constructed from durable materials like epoxy, powder-coated steel, or Al-Zn coated steel, ensuring long service life even in harsh industrial conditions.

Performance Parameters

With a cooling capacity range of 20 ~ 150 kW, this compact air cooler delivers robust cooling power for high-density cold storage and rapid freezing tasks. Its offset geometry and dual-side air intake, downward exhaust design ensure uniform airflow distribution, while AC or EC fan motors optimize energy consumption. The patented reversible airflow system enhances heat exchange efficiency, reducing energy usage while maintaining consistent temperatures.

Core Features

Patented Reversible Airflow Technology

The CMD series leverages a unique reversible airflow system, a key advantage of these Dual discharge air coolers. This technology creates superior air circulation patterns, ensuring full product surface coverage and eliminating hot spots in freezing tunnels—critical for maintaining product quality in industrial settings.

Dual Defrost System for Reliability

Equipped with standard water spray and hot gas defrost options, this unit cooler minimizes defrost duration and frequency. The dual defrost design reduces downtime, improves operational efficiency, and prevents ice buildup, aligning with the eco-friendly focus of a ECO cubic air cooler.

Ice-Protected Fan Operation

Dual-layer splash guards effectively separate defrost water from axial fans, eliminating ice accumulation and potential fan damage. This protective feature extends equipment lifespan and reduces maintenance needs, a vital benefit for industrial air coolers in continuous-operation environments.

Space-Saving & Energy-Efficient Design

As a true compact air cooler, the CMD series excels in width/height limited installations. Its cubic design optimizes cold storage real estate, while low energy consumption reduces operational costs—making it a sustainable choice for modern industrial facilities.

Application Scenarios

Individual Quick Freezing (IQF) Lines

Ideal for IQF production, this Stainless Steel air cooler (when specified) meets food safety standards while delivering rapid, uniform freezing. The reversible airflow ensures each product piece is evenly cooled, preserving texture and quality.

Blast Freezing Operations

In blast freezing chambers, the high-pressure fans of these Dual discharge air coolers generate powerful downward airflow, accelerating the freezing process and increasing production throughput. Customers have reported significant improvements in production efficiency after installation.

High-Density Cold Storage

For facilities with limited space, the compact air cooler design maximizes storage capacity without sacrificing cooling performance. It maintains consistent temperatures across dense product loads, reducing goods weight loss and waste.

Food Processing Pre-Cooling

In food processing plants, the cooler’s efficient heat exchange ensures quick pre-cooling of raw materials, extending shelf life and maintaining freshness—essential for meeting industry quality standards.

FAQ About Dual Discharge Compact Air Cooler

Is the CMD series suitable for small cold rooms with limited height?

Yes. As a compact air cooler, it is specifically engineered for width/height constrained installations, making it perfect for small cold rooms or freezing tunnels where space is at a premium.

Can this cooler use eco-friendly refrigerants like CO₂?

Absolutely. This unit cooler is compatible with CO₂, NH₃, and other eco-friendly refrigerants, supporting sustainable industrial refrigeration practices.

How often does the defrost system need maintenance?

The dual defrost system (water spray + hot gas) reduces maintenance frequency. Routine checks every 3-6 months are recommended, but the design minimizes the need for frequent interventions—ideal for busy industrial air coolers setups.

Does the cubic air cooler with AlMg fins offer better performance than aluminum fins?

AlMg fins provide enhanced durability and heat transfer efficiency compared to standard aluminum fins. The cubic air cooler with AlMg fins option is particularly suitable for high-humidity or corrosive industrial environments.
