Japan Blood Products Organization Kyoto Plant

High-performance once-through boiler with reliable maintenance support

Japan Blood Products Organization Kyoto Plant

They were established in 2012 with the goal of achieving domestic self-sufficiency and a stable supply of blood donations. They convert blood donations of goodwill into plasma fractionated products and supply them to medical institutions that support those who need them. Their Kyoto plant is one of the largest manufacturing facilities for plasma fractionated products in Japan.

Reason for Selection

Boiler replacement along with pure water equipment renewal
Emphasis on maintenance support, not just products

We use boilers to produce “pure water” that is safe for the human body. The boilers are a piece of equipment that can never be shut down in order to provide a stable supply of pharmaceutical products to the medical field. We decided to replace our old boilers with new NTEC boilers after considering not only the energy efficiency and performance, but also the maintenance system. We were reassured by their sales and maintenance staff’s words, “You can trust us with our service!” The boiler replacement has reduced our fuel consumption and we are very pleased with the energy savings.

Super EQOS

Compact and high-efficiency 3t/h once-through boiler

We proposed that they replace the old boilers (once-through boiler [2t/h] x 8 units) with new ones (Super EQOS EQi-3000NM [3t/h] x 5 units). This model produces the largest amount of evaporation as a small boiler, and we are confident in its efficiency and functionality. Since their boilers are used for the manufacture of medical products and they also pay great attention to the boiler water treatment, we installed a dissolved oxygen monitor for the feed water to the boiler system. We also provide the best maintenance and inspection services by checking the status of the boiler equipment and fulfilling their requests to make sure that the equipment is not shut down due to malfunction.

Customer Evaluation

They were concerned not only with the performance of a boiler, but also with safety and security. Initially, they were apprehensive about switching from our competitor’s boilers to ours, but thanks to the prompt and friendly response from our maintenance staff and the maintenance service that meets their needs, they are now using the boilers with peace of mind and satisfaction.

Improvement of energy saving and work environment

Kirin Beer Hokkaido Chitose Factory

They produce the Kirin’s flagship brands such as the Ichiban Shibori and the Lager, and are a manufacturing base for the Hokkaido region. The expansive factory is surrounded by greenery and regularly hosts events. They also offer factory tours that allow visitors to see their production facility up close (reservation required). It is a popular spot not only for families, but also for local residents as an “adult social tour”.

Reason for Selection

Heat generation for essential wheat and rice preparation process
Expectation of energy savings and other benefits

Every year, we have taken energy-saving measures for steam boilers, which are the heat generation equipment for boiling wheat and rice, the raw materials for beer. NTEC proposed the “F-nex” system as one of these energy-saving measures. When we heard from them that this system could recover the hot air in the boiler room and use it as thermal energy, we immediately reached a consensus within our company and decided to adopt it. As a result, the energy savings and improvement of the working environment in the boiler room exceeded our expectations. We were also reassured by their prompt response and are impressed by their speedy and accurate proposals as they actually survey the site.

Energy savings and additional improvement by heating feedwater with high-efficiency heat pump

The boiler room was as hot as a sauna. We proposed the “F-nex” system to them, which uses a heat pump to recover the hot air and raise the boiler feed water temperature. As a result, the boiler room temperature has been lowered by effectively recovering the heat and their working environment has been improved.

Effects

Improved system efficiency through effective hot air recovery reduces fuel costs and CO2 emissions, and lowers the boiler room temperature, improving the working environment.

Fuel costs down by approx. 1,000 thousand yen per year
CO2 emissions down by approx. 30t CO2 per year

Improving the
work environment
in the boiler room

Cool air from the heat pump lowers the temperature in the boiler room and improves the working environment.

Boiler replacement with the high-efficiency
/high-function Super EQOS boiler for energy savings

Our previous 10 t/h and 8 t/h firetube boilers had aged and we decided to install the high-performance and high-efficiency EQi-6001 boilers after internal discussions based on various proposals from NTEC, including energy saving. We are now amazed at the great energy saving effects and the overwhelmingly stable steam pressure.

The Super EQOS EQi-6001 boiler has extremely high energy-saving performance and can control the combustion rate according to the load of their equipment, and they are satisfied with its energy-saving effects and stable steam supply after installation. The EQi-6001 has also been highly evaluated for its combination operation with the existing boilers. We will continue to provide “good products and services” to our overseas customers in the same way as we do in Japan.

Hybrid heat exchange boiler body “Hi”

EQS-1002

Through in-depth analysis of heat exchange in the convection heat transfer section of a boiler body, we have completed a new high-efficiency boiler body (Hybrid heat exchange boiler body “Hi”) by optimizing the combination of three types of fins. The high-speed combustion gas generates intense vortex between the water tube groups, which enhances the heat transfer effect as well as a self-cleaning effect that prevents soot adhesion and growth. This high-efficiency boiler body simultaneously achieves great heat transfer efficiency and durability/stability.
