Manufacturer: Nissan Tanaka
Model: SC-930SS (SC-930SSA, SC-930SSY)

Stainless steel changer SC-930SS made of SUS・Standard and High-Purity Gas Use.
Low-pressure type
Stainless Changer SC-930SSA

Features

• A semi-automatic switching device based on the reliable and proven ‘S-LABO regulator.
• Adopts a stainless diaphragm, making it ideal for high-purity gases, including standard gases, and laser gases.
• Automatically switches between left and right gas supply lines, allowing continuous and long-duration gas supply.
• The two-stage pressure reduction structure enables stable pressure delivery at the outlet.
• It can be used with flammable gases because it doesn’t use electricity as the power source for automatic switching.

Flow characteristics

Medium-pressure (0.7MPa) Supply Type
Stainless Changer SC-930SSY

Features

• While it can be supplied at pressures of 0.5MPa or higher (up to a maximum of 0.7MPa), by keeping the intermediate pressure (P2) below 1.0MPa, it falls outside the category of ‘high-pressure gas manufacturing facilities.
• Adopts a stainless diaphragm, making it ideal for high-purity gases, including standard gases, and laser gases.
• Automatically switches between left and right gas supply lines, allowing continuous and long-duration gas supply.
• The two-stage pressure reduction structure enables stable pressure delivery at the outlet.
• It can be used with flammable gases because it doesn’t use electricity as the power source for automatic switching.

Flow characteristics

Specifications

• If the pressure (intermediate pressure) between the switching regulator and the supply pressure regulator exceeds 1.0MPa, a semi-automatic switching device is considered as high-pressure gas manufacturing facility.
• Usually, with a supply pressure of 0.5MPa or higher, the intermediate pressure exceeds 1.0MPa. However, SC-930 SSY achieves a switching pressure setting that does not exceed 1.0MPa through the optimization of internal components!
• By adopting SC-930 SSY, it becomes easy to provide gas at 0.5-0.7MPa, eliminating the need for procedures required for conventional high-pressure gas manufacturing facilities!

※ We also offer supply frame fabrication. Please consult with your sales representative.
※ We can also accommodate pressure gauges with contacts for flammable gases. Please consult with your sales representative.
※ If gas is supplied at a flow rate exceeding the upper limit of the usage flow range, there is a possibility that gas may be supplied from both systems.
