Energy-saving device "Riduck" for refrigerators and air conditioning units.

last updated：Sep 10, 2026

An energy-saving device that contributes to maintaining the quality of frozen fruits and reducing electricity costs.

In the frozen fruit industry, stable temperature management is essential to maintain product quality. In particular, the operation of freezing equipment is crucial for preserving the freshness of frozen fruits, and the electricity costs associated with this represent a significant portion of manufacturing expenses. Many companies are facing challenges such as rising electricity costs, limitations of energy-saving measures, and insufficient budgets for equipment upgrades. In this context, the energy-saving device "Riduck," which can be retrofitted to existing freezing equipment to reduce power consumption, contributes to solving these issues. 【Usage Scenarios】 - Reducing electricity costs for freezing equipment in frozen fruit factories - Continuous power cost control in frozen fruit storage warehouses 【Benefits of Implementation】 - Reduction in power consumption due to decreased compressor load on freezing equipment - Improvement in management costs through an average 20% reduction in electricity expenses - Ability to specifically verify effectiveness before implementation through free measurement verification - Reduction in CO2 emissions and prolongation of equipment lifespan

basic information

【Features】 - Can be retrofitted to existing refrigeration units without the need for equipment updates. - By simply attaching it to the outside of the refrigerant piping, it reduces the load on the compressor and decreases power consumption. - Free measurement verification (regression analysis) allows for pre-confirmation of effectiveness before implementation. - The average payback period is 2 to 3 years, allowing for early cost recovery. - One unit can support up to four refrigeration units. 【Our Strengths】 AIM Corporation is a technology manufacturer dedicated to solving societal issues from two perspectives: ensuring the safety of our customers' buildings and considering the global environment, under the theme of "Protecting the future of people and the Earth through disaster prevention and energy conservation." We specialize in proposals that achieve sustainable management and a healthy, safe environment without the need for large-scale capital investment or rebuilding, by making the most of existing buildings and facilities. In our disaster prevention business, we provide seismic reinforcement and diagnosis for wooden houses, while in our energy conservation business, we deliver four values (disaster prevention, energy conservation, environment, health) through reducing electricity costs for commercial refrigeration and air conditioning units.
