The "Small Humidifier HG100" is a device that humidifies by bubbling gas into purified water with precisely controlled temperature. Since the liquid temperature reaches the dew point of the generated gas, anyone can easily control the gas dew point. Being a compact humidifier, it is ideal for miniaturizing gas supply systems for fuel cells, especially excelling in the vertical direction (approximately 2,500mm in height). Additionally, due to the small internal liquid volume, it allows for quick dew point switching compared to bubbling types. Furthermore, it is equipped with a float-type liquid level sensor, enabling accurate liquid level management without malfunction. For more details, please contact us or refer to the catalog.

The "Fuel Cell Test Gas Supply Device FCG-100" is a gas supply device for evaluating the performance of fuel cells. It allows for precise control of gas flow and dew point. It is equipped with a pure water replenishment pump system linked to the humidifier's liquid level sensor, enabling long-duration continuous testing. Being a compact gas supply device, it does not require much space. Additionally, due to the low liquid volume inside the humidifier, changes in the dew point can be made quickly. Furthermore, it features a temperature control function for the gas supply line, ensuring a stable dew point is provided. In the event that the internal water level sensor of the humidifier falls below the 'L' level, the heater will not operate, ensuring safety.

The DryCalML series is a high-precision flow meter using a piston prover method, making it ideal as a calibration standard for various flow meters. It is not only traceable to NIST but also certified within Japan. This product is from BIOS, a U.S. company, and has a proven track record as a flow calibrator and sampling flow meter in countries around the world. By measuring the movement speed of a graphite piston inside the cell with a photo sensor, it eliminates the need for water or surfactants, thus removing error factors such as water vapor correction and enabling high-precision measurements. Additionally, we offer a compact, lightweight, and low-cost portable reference flow meter, the Definer220/Defender500 series. For more details, please contact us or refer to the catalog.

The exhaust pressure controller AP310-RV is a controller that regulates the exhaust side pressure within fuel cells and containers (chambers). It is ideal for a wide range of pressure control from 100 to 500 kPa abs. By controlling the dome pressure (diaphragm chamber) pressure in the regulator pneumatically, it achieves a simple and compact design. Additionally, the micro-pressure control exhaust pressure controller AP300 is a controller that regulates the exhaust pressure of process equipment at atmospheric pressure. It has a built-in differential pressure sensor and automatically controls to reach a user-defined pressure value. For more details, please contact us or refer to the catalog.

• Pressure Control

The AP160M controls the pressure within a designated piping by analogically controlling the opening of a proportional solenoid valve. This device is designed to accommodate clean gases, such as those used in semiconductors, with pressure sensors and gas-contacting parts made entirely of metal. The CV150 series also controls the pressure within a designated piping by analogically controlling the opening of a proportional solenoid valve. This device does not have a built-in pressure sensor, allowing for different functions compared to models with integrated sensors by using external pressure or flow sensors.

• Pressure Control

A diaphragm-dome structure that minimizes pressure fluctuations. By adopting a unique pneumatic control system, it automatically adjusts fluid pressure with high precision and large flow rates. The automatic pressure controller AP200 series receives signals from pressure sensors installed on the secondary side and automatically regulates to any set pressure. This device features a springless valve structure to accommodate UHP gases and corrosive gases. Unlike manual pressure regulators, it does not experience pressure fluctuations due to changes in flow rate, enabling stable pressure control.

• Pressure Control

This exhaust pressure controller is a device designed to prevent fluctuations in the manufacturing process caused by pressure variations in the exhaust duct line, including in single-sheet cleaning devices. It enables high-speed pressure control with a compact design and extremely low pressure loss through a uniquely developed pneumatic-driven rubber expansion valve. By properly controlling the exhaust pressure, the exhaust flow rate can also be managed appropriately, allowing for significant reductions in energy costs through comprehensive management of total flow and pressure in the exhaust duct.
