Floor Type Evaporator Manufacturers

Floor Type Evaporator, also known as a floor-mounted air cooler, is a high-capacity heat exchange unit specifically engineered for large-scale industrial refrigeration and cold chain logistics. Unlike ceiling-mounted units, the Floor Type Evaporator is installed directly on the ground, allowing for larger coil surfaces and more powerful airflow throw, which are essential for maintaining stable temperatures in expansive spaces.

With nearly 30 years of expertise, Zhejiang Kaidi Refrigeration Equipment Co., Ltd (Kaidi) has refined the Floor Type Evaporator to deliver peak thermal efficiency. These units are characterized by their robust structural design, optimized fin spacing to prevent frost buildup, and high-performance centrifugal or axial fans, making them the cornerstone of modern industrial cold storage systems.

1. Working Principle and Core Technology

The Floor Type Evaporator operates on the principle of forced convection. Refrigerant flows through the internal copper or aluminum tubes, absorbing heat from the ambient air drawn in by powerful fans.

• Heat Exchange Process: Warm air from the cold room enters the unit, passes over the chilled fins, and is discharged back into the room at a lower temperature.

• Kaidi Engineering Advantage: Our units utilize advanced CNC-machined internal grooved copper tubes and corrugated aluminum fins. This increases the turbulence of the refrigerant, significantly enhancing the heat transfer coefficient compared to standard smooth-tube designs.

2. Product Specifications & Comparison

Choosing the right equipment depends on your specific storage requirements. Below is a comparison between standard industry models and Kaidi’s high-efficiency series.

3. Application Scenarios & Case Studies

Kaidi products are deployed globally, providing reliable cooling for various demanding environments:

• Logistics Distribution Centers: Large-scale "Kaideli" brand floor units ensure uniform temperature distribution in 10,000+ square meter warehouses.

• Blast Freezing: Specialized floor evaporators are used in meat and seafood processing where temperatures must drop to $-35^{\circ}C$ rapidly.

• Fruit & Vegetable Bulk Storage: Precision humidity control integrated into our floor units prevents product dehydration.

Professional Insight: In a recent project for a 60,000m² modern facility, Kaidi implemented floor-mounted units with customized long-distance air ducts, reducing temperature fluctuations to within $\pm 0.5^{\circ}C$.

4. Maintenance and Longevity Guide

To ensure your Floor Type Evaporator maintains peak performance, Kaidi’s after-sales service team recommends the following maintenance schedule:

1. Monthly Fin Inspection: Check for debris or ice bridging. Kaidi units feature easy-access side panels for quick cleaning.

2. Defrost System Check: Verify that electric heaters or water spray nozzles are functioning to prevent ice accumulation, which can reduce airflow efficiency.

3. Motor Lubrication: Inspect fan bearings every six months. We use high-grade, low-temperature resistant lubricants to ensure operation in extreme cold.

4. Leak Detection: Regular pressure testing of the coil system. Our factory-tested units undergo rigorous high-pressure nitrogen testing before shipment.

5. Frequently Asked Questions (FAQ)

Q: When should I choose a Floor Type Evaporator over a Ceiling Type?

A: Floor units are preferred when the cold room height exceeds 6 meters or when the cooling load is exceptionally high. They offer easier maintenance access and much longer air throw distances compared to ceiling units.

Q: How does Kaidi handle customized requirements?

A: As a scientific and technological company, our R&D center in Shanghai specializes in "pre-sales program design." We tailor the coil circuiting, fin material, and fan power based on your specific refrigerant (Freon, $CO_{2}$, or Ammonia) and room dimensions.

Q: Is the "Kaideli" brand available internationally?

A: Yes. While headquartered in Zhejiang, our sales and service network has expanded globally over the past few years, supported by our standardized and efficient operation system.

Q: What defrosting method is most efficient for floor units?

A: For large industrial applications, Kaidi often recommends Water Defrost or Hot Gas Defrost. These methods are faster and more energy-efficient than electric heating for high-capacity evaporators.
