Tan Long Factory Standard Technical Specifications Matrix
1. Next-Generation Asymmetric Twin Screw Rotor Geometry
Screw compressors distributed by Tan Long incorporate state-of-the-art 5:6 or 4:6 rotor profiles:
• Minimizes internal bypass leakage, elevating volumetric efficiency above 92%.
• Radial and thrust bearings with 3x extended operating life compared to conventional designs.
• Wide compression ratios, perfectly tailored for chilled rooms (+5°C), freezers (-25°C), and ultra-low IQF tunnels (-45°C).
2. Advanced Oil Management & Dynamic Equalization System
Lubrication is the lifeblood of screw compressors. Tan Long engineers:
• Centrifugal oil separators paired with 3-stage coalescing filters capturing 99.9% of micron-sized oil aerosols.
• Shell-and-tube water oil coolers or thermosyphon refrigerant cooling maintaining stable oil temperatures at 45°C - 55°C.
• Optoelectronic oil level switches and automatic oil return solenoids preventing oil starvation.
3. Multi-Compressor Rack Automation (Rack Master Controller)
For multi-compressor parallel central stations, Tan Long’s PLC automates rotational lead-lag cycling to balance running hours, sequencing compressors according to actual thermal loads to shave max electrical peak demand.
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
- ✓ 100% genuine imported compressors with full CO/CQ documentation from Germany, Japan, Taiwan
- ✓ Ultra-high 99.9% efficiency oil separation system completely preventing oil fouling on evaporator coils
- ✓ Integrated VFD inverters and smart step loading algorithms minimizing inrush starting current
- ✓ Factory-certified preventive maintenance teams providing 24/7 on-site oil and filter replacement
Drawbacks of Manual / Used Imported Systems
- ✗ Conventional importers quote high markups for generic pre-packaged imported assemblies
- ✗ Local scrap workshops often recondition salvage compressors, risking seized rotors within months
- ✗ Crude local oil separators allow heavy oil carryover into coils, degrading cooling capacity
- ✗ Absence of laser alignment causes severe vibrations, cracking copper refrigerant piping
Frequently Asked Questions (FAQs) by Engineers & Investors
Q1: Should a seafood processing plant select Ammonia (NH3) or Freon screw compressors?
For large seafood cold stores and freezing tunnels (above 150 HP), NH3 Mycom/Bitzer screw systems are the superior choice due to low refrigerant costs, exceptionally high thermodynamic COP, and 15% - 20% power savings compared to Freon. For compact facilities under 100 HP, Bitzer/Hanbell Freon systems offer convenient footprints without requiring dedicated machinery rooms.
Q2: What is Tan Long’s warranty policy for industrial compressor racks?
Tan Long provides a comprehensive 24-month manufacturer warranty across all packaged compressor racks. Every 3 months, Tan Long service engineers conduct vibration analysis, oil condition sampling, and electrical parameter logging completely free of charge.
