Description

APACK succeeded in developing the products employing technologies to secure all the source technologies required for production, provides engineering for any adaptive areas, and guarantees a thorough after-sales services. APACK applies the technologies of vacuum and heat pipes to the products to reduce heat loss (e.g. conduction and convection) from the solar heat absorption plates by 95%, reduce about 30% the installation area. These high efficiency products are available for industrial process heating, as well as hot water Supply, and air conditioning (heating, cooling) in large buildings.

Core Technology

Glass/copper tube joining technology

  • Core technology for maintaining high vacuum level
  • First to be developed internally (third in the world)

Manifold heat-exchange technology

  • Employing pre-cast fins for enlarging the heat conductivity area
  • Dry connection heat-exchange mode for simple installation and maintenance, repair

Heat pipe technology

  • Employing heat pipes with excellent heat response and heat transportation
  • Evaporation allowed without external power, repeat condensation processes

Heat collector plate welding technology

  • Coating particulaly titanium with excellent absorption rate and lower emissions
  • Ultrasonic welding of heat pipes and heat collector plates

High Performance

  • Vacuum technology reduce thermal loss (e.g. conduction and convection) from the solar collector plates for a high-efficient performance, particularly heat collection efficiency in winter seasons
  • Heat pipes are applied for their fast thermal response and excellent heat transfer
  • Both directly reached and scattered solar radiations are effectively applied ideal for the climatic conditions of large scattered radiation
  • Suitable for industrial process, large-scale hot water supply, and air-conditioning (heating, cooling) in large buildings(80~150°C)
  • Easy maintenance (without moving part)
  • No restriction on the installation angle

Compant Size

  • Enhancing efficient use of space (engineering and installation)
  • Utilization of exterior factors of buildings

New & Renewable Energy Certification

  • Performance Certification : Korea Energy Management Corporation
  • Company Certification : Ministry of Commerce, Industry and Energy

New Technology

  • Patented technologies applied such as joining glass with copper tubing
  • Dry connection heat-exchange mode of heat pipes and manifolds (Efficient maintenance)

Easy Maintenance

  • Core technologies preserved for vacuum tube type solar collectors (prompt troubleshooting for any defects during operation)
  • Domestic manufacture of vacuum tube type solar collectors (easy maintenance and prompt supply of materials for after-sales services)
  • Remote system control and monitoring via the Internet (periodic preventive maintenance available)

Application

  • Low temperature industrial processes (lower than 100°C)
    - Hot water for foodstuff container (bottles and cans) cleaning, dying process and concrete block curing
  • Medium temperature industrial processes (100-150°C)
    - Drying process in foodstuff process, textile manufacture, paper and pulp mills
  • Large-scale hot water supply and air-conditioning (heating, cooling) in large buildings
    - Public building and welfare facilities, apartment building and commercial buildings
  • Replacement of energy sources in rural areas
    - Greenhouses, fish-farm and sewage treatment plants
