カシワテック List of Products and Services

We handle "firefighting equipment for other vessels" installed on fireboats, tugboats, patrol boats, etc., and we have a track record of supplying over 2,000 vessels. We offer "water cannons" that can discharge water at rates from 500L to 25,000L per minute, "water towers" that allow for high-position discharges, and "powder extinguishing systems" that can be effectively combined with water towers (spray towers) for effective firefighting. Please feel free to consult us if you have any requests. 【Products We Handle】 ■ Water Cannons ■ Water Towers ■ Powder Extinguishing Systems ■ Oil Spill Treatment Equipment ■ Salvage Systems (Drainage Equipment) *For more details, please download the PDF or feel free to contact us.

• Fire extinguishing equipment

Our company offers a "membrane nitrogen generator" that utilizes air separation technology in non-low temperature conditions, using a membrane that separates nitrogen based on relative permeability by passing air through hollow fiber membranes. Unwanted components (such as oxygen) are simply released into the atmosphere, and no other waste is generated, allowing for the production of very clean and dry inert gas. Additionally, we provide designs tailored to your needs, ranging from small to large capacities, with N2 purity levels from 95% to 99.9%. 【Components】 ■ Air Compressor ■ Air Treatment Unit ■ Membrane Unit *For more details, please download the PDF or feel free to contact us.

• Gas equipment

Our company offers an "Inert Gas Generating Device" that uses an oil burner equipped to burn diesel or heavy oil A, producing combustion gas that is cooled and cleaned by a scrubber to generate clean inert gas. It can be operated via a control panel equipped in the IGG unit. Compared to inert gas systems that utilize combustion gas from auxiliary boilers, it can supply cleaner inert gas. Additionally, you can choose from two types of backflow prevention devices: deck water seal and double block & bleed valve. 【Components】 ■ Inert Gas Generating Device (IGG) unit (burner, scrubber, control panel, etc.) ■ Monitor panel ■ Fuel oil pump unit ■ Blower ■ Oxygen analyzer ■ Control valve ■ Backflow prevention device ■ Oxygen analyzer *For more details, please download the PDF or feel free to contact us.

Our "Inert Gas System" employs the best level of venturi scrubbers for wet dust collection and uses high-performance packing materials in the packing tower for desulfurization, resulting in a device that generates clean inert gas. To prevent severe corrosion from sulfur dioxide in exhaust gases, we utilize corrosion-resistant steel and incorporate advanced anti-corrosion designs such as special coatings and rubber linings. Additionally, by equipping an optional inert gas generator, this device can serve as a source of inert gas during topping up when a small amount of inert gas is required at sea, without the need to operate the inert gas system itself. [Optional] ■ Topping Up Inert Gas Generator *For more details, please download the PDF or feel free to contact us.

We offer "automatic sprinkler systems," designed to detect fires and operate automatically, as well as "manual sprinkler systems and pressurized water spray systems," which can instantly release water into the target area by opening a valve. These systems enable rapid water release in fire zones, contributing to effective initial response during a fire outbreak. 【Features】 ■ Automatic Sprinkler System - Mainly adopted in passenger ship living quarters - Operates automatically, requiring no action from the crew - Emits a visible and audible alarm upon activation, notifying the crew of the fire location - Activates at specified temperatures in living and operational areas ■ Manual Sprinkler System and Pressurized Water Spray System - Mainly adopted on the vehicle decks of RO-RO ships - Allows for initial firefighting by manually opening the valve in the target area *For more details, please download the PDF or feel free to contact us.

We have developed a fixed gas fire extinguishing system using the fire extinguishing agent "3M(TM) Novec(TM) 1230," which was developed by 3M Company in the United States for total flooding applications. "Novec(TM) 1230" vaporizes immediately upon being released from the nozzle, achieving extinguishment through a cooling effect. Since it does not rely on suffocation for extinguishment and the extinguishing agent itself is low in toxicity, it offers high safety. The number of required cylinders is about two-thirds compared to carbon dioxide and about half compared to nitrogen gas, allowing for effective use of space. 【Features】 ■ Vaporizes upon release from the nozzle, achieving extinguishment through cooling effect ■ Low toxicity and high safety ■ Reduction in the number of cylinders allows for effective use of space ■ Excellent environmental characteristics ■ Short extinguishment time reduces heat damage *For more details, please download the PDF or feel free to contact us.

The FMS (Fixed Monitor System) is a helicopter deck foam firefighting device consisting of a foam monitor placed on the helideck and a fire extinguishing liquid tank unit that includes a fire extinguishing liquid pump and a foam mixing device. The extinguishing liquid uses Aqueous Film Forming Foam (AFFF), which is effective for extinguishing aircraft fuel fires. This device, which is generally operated manually, incorporates a self-oscillation mechanism that automatically rotates the monitor left and right at a pre-set angle, releasing low-expansion foam over a designated area, allowing for remote start and stop operations. 【Components】 ■ Foam Monitor ■ Fire Extinguishing Liquid Tank Unit (including fire extinguishing liquid pump and foam mixing device) *For more details, please download the PDF or feel free to contact us.

Our company handles the "Deck Foam Fire Extinguishing System," which uses the jet action of water flow to vigorously mix foam concentrate and seawater in the piping, creating foam that incorporates air for fire extinguishing. The foaming method adopted in this system, "Air Foam," excels in fire resistance and oil resistance compared to chemical foam (foam generated by chemical reactions) and has the characteristic of foaming without issues when mixed with seawater. 【Components】 ■ Fire extinguishing liquid tank ■ Fire extinguishing liquid pump ■ Mixing device ■ Manual valve ■ Foam monitor, etc. *For more details, please download the PDF or feel free to contact us.

• Fire extinguishing equipment

Our company offers a "local fire extinguishing device" that extinguishes fires using safe water mist particles without the use of chemicals or gases for crew safety. We conduct safety evaluation tests of water spray on electrical equipment, assess the impact of engine room ventilation on extinguishing capability, and propose methods such as the side shot method, which is suitable for extinguishing the main engine. By solving many issues during practical application, we have received high international recognition. Please feel free to consult us if you have any requests. 【Components】 ■ Pump unit (a unit combining clean water pump, pump starter, and distribution valve) ■ Spray nozzle ■ Control panels ■ Clean water tank, etc. *For more details, please download the PDF or feel free to contact us.

Our company offers a safe and high-performance inside air-type "high expansion foam fire extinguishing system" for engine rooms and pump rooms on ships. The foam solution (fire extinguishing liquid) primarily composed of synthetic surfactants is mixed with seawater (or fresh water) and sprayed onto a metal foaming net, generating foam that performs fire extinguishing operations through cooling and smothering effects. Thanks to the various stabilizers contained in the fire extinguishing liquid, it has strong fire resistance and can effectively extinguish a wide range of fires, including oil fires from gasoline, naphtha, heavy oil, and light oil, as well as fires involving wood and fabric. 【Components】 ■ Fire extinguishing liquid tank ■ Fire extinguishing liquid pump ■ Mixing device ■ Manual/automatic valve ■ Foam generator ■ Control panel, etc. *For more details, please download the PDF or feel free to contact us.

We handle the marine exhaust gas cleaning system from Clean Marine, which can process all exhaust gases (M/E, A/E, Boiler) with a single scrubber. It flexibly adapts to variations in allowable back pressure due to load fluctuations in diesel engines, making it a cost-effective system. 【Features】 ■ Zero back pressure "Allstream-EGCS" ■ NaOH assist method that is not dependent on water quality ■ High-efficiency cyclone system *For more details, please download the PDF or contact us.
