Product Overview

In a radiant air conditioning system that can achieve both comfort and energy conservation, it plays an important role mainly in absorbing heat generated by the human body.
Heating and cooling happen by passing water at nearly normal temperatures (20°C in summer and 26°C in winter) through a three-layer pipe made of resin and aluminum.
The water efficiently transmits the temperature to the radiant panel, which keeps an almost uniform temperature, ensuring a comfortable environment with minimal noticeable temperature differences

Features

Various design variations
High-performance aluminum panels reduce the number of panels required
Aluminum-core polyethylene triple-layer pipes provide high durability
Same weight as standard rock wool sound-absorbing panels for ceilings
Can install by ceiling and plumbing contractors

Features

• It has a special structure where the cooling water does not come into direct contact with the outer cylinder of the roll

Manufactures: Sasakura Engineering co,ltd.

Product Overview

A high-pressure pump applies pressure to seawater through a membrane that has the special property of allowing water to pass through but not salt, extracting only the fresh water.

Features

We manufacture a wide range of units, from small ones with a daily water production capacity of around 300 liters to large ones with a capacity of 100 tons, and they are used for everything from small fishing boats to passenger ships that require large amounts of water.

Product Overview

The multi-stage flash type uses low-pressure steam to heat seawater, efficiently producing large volumes of fresh water with minimal heat. It generates between 100 and 1,000 tons of water daily, making it ideal for passenger ships and fishing boats needing substantial fresh water supplies.

Product Overview

Installed on ships with steam turbine engines like LNG carriers, this system uses low-pressure steam from the turbine to heat seawater. The resulting steam cools and condenses with seawater, efficiently producing high-purity fresh water and ensuring a steady supply for high-pressure steam boilers.

Features

The compact evaporator, heater, pump, and piping unit reliably supplies high-purity water for high-pressure steam boilers. Using condensate from the steam turbine engine as cooling water boosts the thermal efficiency of the engine.

Product Overview

Installed on LNG carriers and similar ships with steam turbine engines, this system uses low-pressure turbine steam to heat seawater. The steam then cools and condenses with seawater, efficiently producing a steady supply of high-purity water for high-pressure steam boilers.

Features

The two-stage flash system efficiently produces water with a production ratio of about 1.5. A compact unit of the evaporator, heater, pump, and piping reliably supplies high-purity water for high-pressure steam boiler feedwater.

Product Overview

The system uses waste heat from diesel engine cooling to evaporate seawater under vacuum, producing high-purity fresh water for drinking, boiler feed, and general use.

Features

The double-effect system features two evaporation chambers, using steam from the first chamber as an efficient heat source for the second chamber. This makes it highly efficient and compact. The triple-effect type has three evaporation chambers and is an even more efficient water production system. It covers a water production volume of 40 tons to 200 tons per day.

Product Overview

This is a new generation water maker that can produce water with less heat.
In recent years, energy conservation has led to a decrease in waste heat from the main engine, resulting in a shortage of heat sources for the water maker, while the demand for fresh water is increasing due to environmental regulations. The WX series high-efficiency water maker was developed to respond to these changes in the ship’s environment.

Features

The highly reliable X-series water maker has been further improved. The water production efficiency is approximately twice that of the X-series. It is ideal for ships that cannot produce the required amount of water due to a lack of heat source, or for ships that require more fresh water than ever before due to SOx NOx regulations. A split type that allows for easy transfer is also available. The ease of use of the X-series is the same, so operation is also easy.
Water production capacity covers 20 to 40 tons per day. As before, water can be produced using steam by adding a steam injector.

Product Overview

The system uses waste heat from diesel engine cooling to evaporate seawater under vacuum, producing high-purity fresh water for drinking, boiler feed, and general use. It comes in two types: tubular and plate.

Features

With over 17,000 units shipped, this popular freshwater generator is widely installed on ships worldwide. Now in its 5th generation X series, it offers two models—the XE and XM types—which vary in cooling seawater supply and ejector pump arrangement.. The water production capacity covers 10 tons to 50 tons per day. Adding a steam injector or steam booster unit allows the system to produce water using steam.

Product Overview

The system uses waste heat from diesel engine cooling to evaporate seawater under vacuum, producing high-purity fresh water suitable for drinking, boiler feed, and general service. There are two types of fresh water generators: tubular type and plate type.

Features

This is a freshwater generator that applies plate heat exchanger technology. By making the heat exchanger coverless, the installation space is small and maintenance and inspection can be easily performed in a short time. The water production capacity is 20 to 45 tons per day. Water can also be produced using steam by adding a steam injector or steam booster unit. There are two types, RE type and RM type, depending on the cooling seawater supply method and ejector pump arrangement.
