• V2, V3

Cryogenic air separators which generate high-purity nitrogen and oxygen by filling LN2 or LO2 as a cooling source instead of using an expansion turbine.

• VPS

Single tower type oxygen gas generator utilizing a pressure vacuum swing adsorption (PVSA) technology with simple structure and high recovery ratio.

• OXY

Energy-saving and small home medical oxygen concentrator with a pressure swing adsorption (PSA) technology.

• LNG containers

Thermal insulation technology to store cryogenic substances (such as liquid nitrogen at -196ºC) maintaining heat invasion at in extremely low level.

• Pulse tube refrigerators

Cryogenically cooling technology utilizing pulse tube refrigeration that achieves high efficiency and high output through an active buffer.

• NV metal surface treatment

A compound metal surface treatment technology combined with the nitriding process, carbon solid-solution diffusion process, and chromium diffusion process.

• Atmospheric pressure plasma

Surface-modification technology generating glow discharge at atmospheric pressure.
This enables glass substrate cleaning, ashing, etching, and improvement in wettability and adhesion performance of plastic films.

• Fuel gas generators for the fusion cutting "Aqua Gas Generator"

a generator which creates a mixture of oxygen and hydrogen gas through the electrolysis of water for gas cutting.
This provides high cutting speed and smooth surface cut with low distortion.

• Natural gas, LPG-based hydrogen generators

Technology for effectively synthesizing hydrogen utilizing the natural gas and LPG as raw materials through a special catalyst.

• VCE

This is an ultra-high vacuum CVD system which provides excellent characteristics in thin film growth including selective growth and a superlattice structure. This system features high performance in film thickness control as well as low contamination, large-area film uniformity, and maintenance-free construction.
