It is ideal for non-corrosive gas applications that require a clean vacuum with high reliability and no oil back-diffusion. 【Features】 ○ Clean vacuum ○ Air-cooled ○ Lightweight and compact ○ Strong against water vapor and mist ○ Low noise and low vibration For more details, please contact us or download the catalog.

• Air compressors, blowers and pumps

Multi-purpose series! Rotary blowers developed based on extensive experience and achievements.

The ARJ type is a rotary blower (Roots blower) that incorporates a three-lobe rotor and brings together the technology of Unosawa Kogyo Co., Ltd. with the aim of achieving high performance, low noise, and low vibration. This series is highly standardized and can be widely used from low pressure to high pressure and from low flow rates to high flow rates. It also accommodates special gases, low-temperature fluids, and high-temperature fluids. 【Features】 ○ High reliability ○ Support for special specifications ○ Selection of optimal shaft sealing structure ○ Support for special materials and surface treatments ○ Support for high-pressure specifications For more details, please contact us or download the catalog.

• Ventilation and smoke exhaust equipment

Extremely robust against condensate! Vertical dry vacuum pump for chemical processes.

The "TRV Series" is a versatile dry vacuum pump (Roots vacuum pump) uniquely developed as a vacuum pump that is strong against condensable gases. The gas flow path is arranged to flow from the top to the bottom in a Down-Flow manner, allowing mist and liquids condensed inside the pump, which are drawn in with the gas, to easily flow down to the discharge port and be expelled or collected under atmospheric pressure. Therefore, it is an extremely robust pump against the inflow of mist and condensate from gases. In addition to the standard FC material, corrosion-resistant materials are also available for selection. 【Features】 ○ Strong against liquids ○ Energy-saving and high-performance design ○ Low temperature rise ○ Capable of drawing high-temperature gases ○ Small installation footprint For more details, please contact us or download the catalog.

• Piping and insulation

Ideal for the suction of condensable gases! General-purpose dry vacuum pump for chemical processes.

The "TRM Series" is a general-purpose dry vacuum pump (Roots vacuum pump) with many years of experience and numerous achievements. It can operate efficiently and stably at a consistent temperature thanks to an intermediate cooler. Additionally, it is capable of recovering condensed liquids such as solvents and is suitable for suctioning condensable gases in processes like vacuum drying, distillation, and degassing. The dry vacuum pump can cover a wide range of pumping speeds from approximately 2m³/min to 35m³/min, and it can also accommodate special specifications made from corrosion-resistant materials such as stainless steel. 【Features】 ○ Wide operating range ○ Completely dry ○ No water contamination ○ Long-term continuous operation For more details, please contact us or download the catalog.

• Ventilation and smoke exhaust equipment

Many achievements in various shaft seals such as mechanical seals and dry gas seals!

The ARJ type is a rotary blower (Roots blower) that incorporates a three-lobe rotor and combines the technology of Unosawa Iron Works Co., Ltd. to achieve high performance, low noise, and low vibration. This series is highly standardized and can be widely used from low pressure to high pressure and from small airflow to large airflow. It also accommodates special gases, low-temperature fluids, and high-temperature fluids. 【Features】 ○ High reliability ○ Support for special specifications ○ Selection of optimal shaft sealing structure ○ Support for special materials and surface treatments ○ Support for high-pressure specifications For more details, please contact us or download the catalog.

Are you making progress on measures for the "2024 Problem"? The management of drivers' working hours is becoming stricter, and in the logistics field, reducing "waiting time for loading" has become an urgent issue. To address this challenge, our company, Hotron, proposes the "Vehicle Detection Ultrasonic Sensor 'HM-UX2'," which instantly grasps the availability of loading bays. The 'HM-UX2' contributes to the resolution of waiting times by accurately understanding the availability status, reducing unnecessary waiting and queuing, and shortening waiting times, thereby alleviating the burden on drivers! By replacing the "eyes" of your loading bay management with this high-precision sensor, why not start taking measures against the "2024 Problem"? Take a look at the product features: "Can it accurately detect availability?" "Can we really use it in our company?" "I just want to know the cost, even if it's an estimate." If you have any questions or requests, please feel free to consult us first.

As a result of the conformity assessment audit of the Information Security Management System (ISMS), which is a management system standard, it has been proven that we comply with the requirements set forth by ISO/IEC, and the following audit registration certificate has been issued: JIP-ISMS517-1.0 (ISO/IEC 27017:2015) Scope of Application * Cloud Service Provider: Provision of "CaaS Cloud" This is based on the general information security standard ISO 27001 (ISMS) and includes additional management measures to address threats and risks specific to cloud services.

The non-contact beam touch sensor "HA-T401/HA-T520" has a compact detection range, making it an ideal automatic door sensor for installation on automatic doors facing narrow corridors or busy streets. Depending on the application and installation location, you can choose between "non-vision mounting type" and "non-vision built-in type." 【Features】 ● With the beam touch sensor, you can open and close the automatic door simply by bringing your hand close without touching it, ensuring hygiene. ● Depending on the installation environment, such as single sliding or bi-parting doors, the detection range can be set in four configurations: left, center, right, and a total of 12 spots. ● Two types of activation row settings are available to reduce unnecessary opening and closing of the automatic door due to cross traffic, contributing to energy-saving effects. ● The touch switch and infrared sensor are integrated, allowing for a switch between beam touch and infrared sensor with a single model. 【Recommended for such locations!】 ☑ Entrance facing a busy corridor ☑ Counter or sign near the door ☑ Buildings facing narrow corridors ☑ Buildings that prioritize aesthetics ☑ Hospitals and facilities that consider hygiene ☑ Large facilities with many doors ◎ For more details, please download the materials or contact us.
