About This Product

■A sure step towards carbon neutrality with high COP operation inherited from EcoCute

In factories that require steam for manufacturing processes, the heat source equipment is often integrated into a steam boiler, which increases the environmental impact of combustion. As factories are strongly required to reduce carbon dioxide emissions, this has become one of the issues that worries users. This product is a heat pump hot water system that solves the problem by preheating the water supplied to the steam boiler. You can control the optimal amount of heat input depending on whether the steam boiler is in operation or not by simply switching the mode. By optimizing feed water preheating, we have reduced the load on the steam boiler and reduced carbon dioxide emissions. By specializing in water supply preheating, it has superior installation costs and ease of installation than the conventional EcoCute, and is a solution that will gradually but surely build toward carbon neutrality.

■Energy-saving economic effects through demonstration tests

By replacing part of combustion (fossil fuel) with heat pump (electricity)...810,000 yen/year reduction

■Energy saving and environmental effects through demonstration tests

Annual CO2 emissions reduced by 29t/year

■Additional benefits

・Uses a SUS316 plate heat exchanger to increase durability - Compact system and easy installation work ・Since CO2 is a safe natural refrigerant, it is not subject to the Freon Emission Control Act (no inspection required by qualified personnel)

■System configuration that is easy to install

A system can be easily constructed by simply installing the PreCute+ tank unit near the boiler room.

■Characteristics of PreCute water supply preheating

・What is important in preheating water supply is not the temperature, but the timely and efficient supply of heat. ・PreCute controls the amount of heat input suitable for preheating depending on whether the steam boiler is in operation or not.
