Preventing 'It Won't Start When I Need It' – Launching a New High-Pressure Washer That Keeps Operations Running

Arimitsu Industrial Co., Ltd. launches a new high-pressure washer equipped with oil temperature detection and dry-run protection to prevent failures and enhance on-site reliability.

Arimitsu Industrial Co., Ltd. (Headquarters: Osaka City; President and CEO: Hiroyuki Arimitsu) announces the launch of a new high-pressure washer designed to reduce failure risks and improve durability.

High-pressure washers are widely used in factories, facilities, construction sites, agriculture, and other fields. However, malfunctions caused by pump overheating or dry running have been major challenges, leading to work stoppages and costly repairs.

Building upon our long-selling models, we have developed a new high-pressure washer equipped with new functions aimed at preventing on-site troubles before they occur.

Development Background

"I tried to start cleaning, but the high-pressure washer wouldn't turn on."

Such sudden malfunctions cause delays and schedule changes in on-site operations, creating significant burdens for customers. In response to these customer concerns, we have pursued development based on the concept of "preventing failures before they happen," rather than "responding after a failure occurs." As a result, we have completed a new model that enhances both durability and protective functions.

Key Features

- Oil Temperature Detection Function

The pump's oil temperature is continuously monitored. If an abnormal temperature rise is detected, the unit automatically stops operation.

This prevents serious issues such as internal pump damage or seizure, reducing the risk of costly repairs. *Note: The oil temperature detection function does not guarantee 100% prevention of pump seizure. Please perform pre-operation checks as instructed in the user manual.

- Dry-Run Protection Function

If a dry-running condition occurs due to insufficient water intake or water supply interruption, the unit automatically stops operation.

This prevents pump damage caused by running without water, contributing to improved equipment durability.

- Automatic Operation Function

Operation is automatically controlled in response to the trigger operation of the cleaning gun.

This reduces unnecessary running time, lessens the load on the pump and motor, and contributes to energy-efficient operation.

- Switch-Left-On Prevention Function

Reduces the risk of the high-pressure washer unintentionally starting or operating during nighttime or non-business hours. This minimizes equipment wear and lowers maintenance costs.

Automatic Shutdown and Warning Light for Abnormalities

When an abnormality is detected, this product automatically shuts down and alerts the user via a warning light.

Equipped with Arimitsu Plunger Pump

This product features the Arimitsu plunger pump, which has received high praise over many years. Thanks to its patented unique structure, it combines excellent durability and maintainability, delivering stable performance even in harsh on-site environments.

Compact Design with High Cleaning Performance

While enhancing functionality, the unit achieves a compact design. It is easy to maneuver in limited spaces and offers excellent storage and portability.

Additionally, it delivers powerful cleaning performance with high-pressure water, effectively removing stubborn dirt.

Wide Range of Optional Accessories

Various optional nozzles can be selected according to application needs:

- Turbo Nozzle - Pipe Cleaning Nozzle - Floor Cleaning Nozzle - Foaming Nozzle

*The above are examples. Usage conditions may vary by model.

Improved Workability with Hose Reel Model

Models equipped with a hose reel allow easy hose retraction and storage, reducing the burden of post-operation organization and transportation. *Optional

Arimitsu Industrial's Vision

Since its founding, Arimitsu Industrial has pursued manufacturing that "never stops on-site operations."

This product was developed not only for cleaning performance but also with a focus on durability that reduces failure risks and supports long-term use.

We will continue to develop products that keep our customers' operations running without interruption.
