Air conditioning equipment is a unit produced by integrating different devices into a unit in order to make the air supplied into the room suitable for the purpose of use.
Air conditioning equipment is comprised of a mixing coil which mixes the air re-circulated into the air with fresh outside air, a cooling coil which reduces moisture in the air during cooling, a heating coil which heats up the air during heating, an air filter which removes impurities such as dust mixed in the air, and a humidifier which sprays water or vapor for humidification during heating, and an eliminator is also installed in some cases for prevention of humidification water from being re-scattered when the wind speed is high.

The quality of the air conditioning equipment manufactured by C&G Technology Co., Ltd. is guaranteed as the components are manufactured in the factory under a plan by type and specification, and the site installation work is also efficiently conducted. Also, large products are designed to allow easy transportation, warehousing and site assembly as they are produced being divided into the blower part, coil part, and filter part.

  • The exterior is beautiful as it is made of aluminum die casting and sanded.
  • At the internal corners, insulators made of EDPM are attached.
  • It is of a structure which can be easily disassembled and re-assembled.

  • Being made by compressing aluminum, it is light and strong enough to play the role of a frame which holds the panel.
  • It is of a structure where heat transfer is blocked by attaching insulators made of EPDM on the internal side of the profile in order to prevent generation of condensate when the weather is hot and humid like in a rainy season.
  • Leakage of air is prevented to the maximum by attaching packings on the part of the wing.

  • It plays the role of strengthening and fixing the panels being located between panels.
  • It is of a structure where heat transfer is blocked by attaching insulators made of polyethylene on the internal side of the profile.

  • It is of thin type filter with small pressure loss.
  • The attached dust is not rescattered.
  • The performance is made uniform by spurting the ribbon material made of past state resin to maintain a constant interval.

  • Galvanized steel sheet with the highest grade surface, beautiful exterior, and high anti-corrosion is used as standard.
  • It is of double skin structure.

A clean room means the space in which the concentration of air floating particles is controlled to be below the specified cleanliness level, the required cleanliness is also maintained for the materials, chemicals, and water supplied to the space, and the environmental conditions such as temperature, humidity, static electricity, indoor pressure, noise and vibration are also controlled and managed as necessary.

Besides, the shape and speed of the indoor air current, harmful gas and indoor illuminance are also required to be included in the items to be managed.
And, clean room is diversely applied not only in the semi-conductor industry but also to a wide range such as precision industry, medicine production, food manufacturing industry, optical machines, hospitals and laboratories.
A bio clean room means a clean room space in which living things and inorganic particles in the indoor air are controlled.

Clean room is created in order to remove the particles floating in the air which cause important interruption during the process of R&D and production in high technology industrial field emerged as technologies advance toward the 21st century.

A clean room means a closed space in which not only the particles floating in the air are controlled but also the temperature, humidity, air pressure, static electricity, and illuminance are environmentally controlled.
