3. Enhanced Thermal Exchange System
• Coil Design: Φ9.52mm micro-grooved copper tubes (HCFC-free compatible)
• Fin Configuration: Sinusoidal aluminum fins (FPI=16) with hydrophilic coating
• Airflow Pattern: Δ-arranged tube matrix enhances NTU by 22% vs conventional designs

4. Performance-Oriented Components

• EC Motor Fans: IP55-rated, Class F insulation (25,000h MTBF)
  ▶ Speed range: 800-1800 RPM (PWM controlled)
  ▶ Operating envelope: -40℃~60℃ ambient temperature

• Defrost System: 316L stainless heating elements with PID control
  ▶ Surface load: ≤1.8W/cm² (UL 1995 compliant)
  ▶ 4-zone thermal distribution (σ≤0.85)

5. Engineering Certifications
✓ Pressure tested at 25bar (362.5psi) per ASME BPVC Section VIII
✓ Refrigerant compatibility: R404A/R507A/R134a/R22 (ASHRAE 34 compliant)
✓ Fin spacing options: 4.5/6.0/9.0mm (EN 327/328 certified)

6. Customization & Quality Control

Zhejiang kaidi refrigeration equipment co.,ltd was established in 1995.It is a refrigeration equipment manufacturing company integrating research and development, processing and manufacturing, sales and commissioning services. The company is headquartered in Cangzhou City, Zhejiang Province. The company covers an area of 50,000 square meters. It has more than 30,000 square meters of modern factory buildings and more than 6,000 square meters of offices. It is equipped with advanced CNC processing equipment and high-standard testing laboratories. The company has a senior professional technical team and an experienced manufacturing team.

Since its establishment, the company has passed the ISO9001 quality management system certification, and has obtained industrial product production licenses and special equipment manufacturing licenses of the People's Republic of China (pressure vessels D1, D2). At present, the company's products mainly include air coolers, air-cooled condensers, shell and tube evaporators, shell and tube condensers, fully enclosed / semi-closed / screw compression condensing units, integrated compression condensing units and larger piston / screw Single and double-stage parallel units, ultra-low temperature air source heat pumps, air source heat pump drying units, water (ground) source heat pumps, etc.

After years of development, we not only have a complete product line, from chiller products and condenser products to different types of compressor units, which can meet the application requirements of different scales and different grades, and we attach great importance to the design support capacity of engineering refrigeration systems. The construction can provide professional technical support for the whole process of the project's pre-design, equipment selection, installation and commissioning to ensure the overall operation of the project. Based on the principle of customer-oriented, we have established a sound modern enterprise system and a comprehensive and effective quality management system, and have a pre-sales and after-sales service system that reflects promptly and thoughtfully.

"Kaidi" brand refrigeration products have a high reputation in China, and have won praise and recognition from customers. At the same time, they have also exported to Russia, Spain, Japan, South Korea, Malaysia, Vietnam and other countries, and have a place in foreign markets.
