Steam Fired Instantaneous Water Heater | One-Way Method
Hot Water Supply System Steam Fired Instantaneous Water Heater | One-Way Method
LM15-Ⅳ
・Passed the test of effect to water quality that meet JIS ・Hot water supply between 40℃ and 70℃ (104°F and 158°F)
Features/Applications
Features
Can be installed in tight spaces thanks to its compact design (small/lightweight).
With a compact size, this product can be wall mounted in the place it is required.
Provides clean hot water
Employs an indirect heating system* with water and steam.
*Indirect heating system refers to a system of heating that uses a heat exchanger and where the water and steam do not come into direct contact.
This means that the quality of the hot water is not impacted by chemicals or other matter in the steam.
Industry top-class hot water supply volume
Compact, yet able to instantaneously supply up to 30ℓ/min of hot water.
High thermal efficiency
Thermal efficiency of 91% that surpasses gas and electric hot water supplies.
Environmentally friendly
With no combustion taking place within the hot water supply itself, it does not produce chemical substances such as CO, CO2, and NOx, nor does it produce soot.
Quiet
Quiet operation with a background noise of around 45dB.
Easy maintenance
Main consumable components are grouped into a unit.
Suitable for use in foodstuff manufacturing
The design of this product passes leaching tests, meaning the water it supplies can be used in foodstuff manufacturing as is.
Typical applications
Can be used in the cleaning of kitchen and kitchen equipment, and as water preparing for food processing.

●Low-temperature options: A 30℃ - 50℃ (86°F - 122°F)type*1 can be manufactured. Please do not hesitate to make inquiries.
*1 The 30℃ - 50℃ (86°F - 122°F) type has not undergone any leaching performance tests.
●In the event of deterioration of internal components, performance may fall below the performance when the product passed its leaching performance test.
