Tan Long Factory Standard Technical Specifications Matrix
1. Water-Cooled Configuration Optimized for Tropical Climates
In tropical zones where summer ambient reaches 38°C - 40°C, Tan Long engineers water-cooled chillers paired with cooling towers:
• Condensing temperature is maintained at a modest 35°C - 37°C, easing compressor pressure ratios.
• COP energy efficiency reaches 4.8 to 5.5, saving hundreds of millions of VND annually for 3-shift facilities.
2. Multi-Tier Anti-Freeze Tube Burst Protection
Water freezing inside shell-and-tube evaporators is a critical chiller hazard. Tan Long integrates 4 independent safeguards:
1. Electronic flow switch tripping compressors immediately if water flow decreases.
2. Antifreeze thermostat cutting out if water drops below +3°C.
3. Low-pressure transducer monitoring instantaneous suction pressure.
4. Micro-stepping electronic expansion valve (EEV) algorithm responding in milliseconds.
3. Industrial Applications Across Manufacturing Facilities
Tan Long industrial water chillers operate across leading facilities:
• KIDO Foods Cu Chi: Glycol chiller (-10°C) powering continuous ice cream manufacturing lines.
• Pharmaceutical cleanrooms and semiconductor plants requiring tight temperature and humidity control under GMP-WHO.
Competitive Advantages & Market Comparison Matrix
Technical comparison between genuine Tan Long refrigeration equipment manufactured at Duc Hoa 1 Industrial Park versus substandard market alternatives:
Tan Long Equipment Advantages
- ✓ Utilizes VFD inverters to maintain chilled water temperature fluctuations within ±0.5°C
- ✓ Shell-and-tube evaporators are easily cleaned mechanically, eliminating clogging risks seen in compact brazed plate chillers
- ✓ 40% lower operating and maintenance costs compared to imported Trane, Carrier, or Daikin chillers
- ✓ 24/7 on-site technical support with genuine compressor and EEV spare parts immediately available
Drawbacks of Manual / Used Imported Systems
- ✗ Imported packaged chillers carry high price tags with 2 - 3 month lead times for replacement controller boards
- ✗ Low-budget uncertified chillers foul rapidly, causing steep drops in cooling capacity
- ✗ Inadequate antifreeze protection leads to tube freeze-bursts and water flooding into refrigeration circuits
- ✗ Proprietary locked control systems that cannot interface with factory-wide SCADA platforms
Frequently Asked Questions (FAQs) by Engineers & Investors
Q1: When to choose water-cooled chillers versus air-cooled chillers?
If the facility has adequate rooftop or yard space and water supply, water-cooled chillers are the premier choice, offering 25% lower power consumption and longer equipment life. If water is constrained or space is limited, air-cooled chillers eliminate cooling towers and condenser water piping.
Q2: What is the delivery and installation lead time for Tan Long chillers?
For standard 50 - 200 HP skids, Tan Long maintains factory stock ready for delivery and installation in 7 - 10 days. Customized high-capacity chillers are delivered within 25 - 35 business days.
