Moreover, the expansion of production activities in human society has drastically changed
the natural water cycle. In some cases, it causes a great impact on human life and human livelihoods.
It is a great challenge for us human beings to keep the Earth, a beautiful water planet,a good place to live.
It is our mission to treat water with care and to reuse it.
With the concept of "taking good care of the water planet" as the backboneof our management philosophy, Shinnihon Reiki continues to make eﬀorts to achieve
our goal of water reuse.

Cooling Tower =The Behind-the-Scenes Driving Forceof the Facility
We provide cooling towers that cool the heat generated
by any kind of industrial facility.

Cooling Tower for DHC
The district heating andcooling (DHC) systems helps
urban development andimprovement, also it is goodidea for eﬀective use ofenergy. Based on our

extensive experience since
1955, we have beendeveloping a series ofcooling towers forlarge-scale cooling andheating facilities to meetcustomer needs.

Noise Abatement (measures)
The source of cooling tower noise is
the sound of the blower and thesound of falling water, which istransmitted outside the tower.
There are two ways to prevent noise:
lowering the sound source itself or
attenuating it by using soundabsorption equipment. For theformer, low-noise blowers are used,
and for the latter, sound-absorbing
louvers, sound-absorbing ducts, andsound insulation walls are used.

● This table is an annual inspection and maintenance plan for 15 years from the next year of operation.
● This table is for a guideline only, as the timing of implementation will vary depending on the operating status of thecooling tower.
● Regarding the replacement schedule of the ﬁlling and drift eliminator, perform a performance test (intangible factors)
and visual inspection (tangible factors) on a regular basis, and plan for replacement inadvance considering the results.
● A separate consultation regarding maintenance time, pricing, etc will be done for other parts and materials that are
determined to require replacement due to operational reasons.
● Overhaul of a gear reducer requires at least 15 days for removal, maintenance at shop, and restoration. If overhaul of all
gear reducers cannot be performed all at once, it is suggested to overhaul one by one
in the cold weather season, orby purchase one gear reducer as a spare part.
