Recently, the warehousing and transportation industries have shown increasing interest in new energy-saving solutions. Among the key challenges are reducing operational costs and mitigating the environmental impact of high energy consumption. To meet the diverse needs of industries such as warehouses, cold storages, quick-freezer warehouses, ice skating rinks, and restaurants, Mayekawa has introduced innovative solutions designed to lower energy consumption and promote sustainability.

This article highlights the features of Mayekawa's innovative solutions, which enhance energy savings through advanced energy management and control systems.

Mayekawa's Cutting-Edge Energy-Saving Refrigerant Unit for Cooling Systems

Our products are designed to reduce energy consumption and CO2 emissions, promoting energy efficiency in refrigerated warehouses.

■ High-Efficiency Natural Refrigerant Freezing Unit: “NH3/CO2 Unit System”

This high-efficiency cooling system was developed with a focus on mitigating global warming. By utilizing natural refrigerants—ammonia and CO2—it reduces the risk of ammonia leakage while minimizing CO2 consumption and emissions. The system is ideal for specialized applications, including warehouses, cold storages, high-quality ice production facilities, ice skating rinks, and other high-performance cooling units.

▲ Structure of the unit

Key Features
・Utilizes environmentally friendly refrigerants
・Incorporates a new screw rotor design for high efficiency and reduced noise
・Features an IPM motor with embedded permanent magnets to lower power consumption
・Employs a shell and plate-type heat exchanger.

■ Heat Insulation Air Curtain “Thermo-shutter”

This horizontal-flow circulation-type heat insulation air curtain is ideal for logistics warehouses, freezer warehouses, and cold storage rooms with varying temperatures. By efficiently blocking the exchange of warm and cold air, it helps maintain a consistent internal temperature, contributing to energy consumption reduction. Additionally, it minimizes condensation within the warehouse and reduces the frequency of defrosting operations. Furthermore, it provides effective protection against insects and dust.

Key Features
・Maintains a consistent internal temperature, helping preserve the quality of stored products
・Minimizes condensation, reducing the frequency of defrosting operations
・Prevents the loss of warm air, improving energy efficiency

■ Mayekawa's Energy-Efficient Natural Refrigerants
For many years, Mayekawa has been developing and manufacturing products and equipment that utilize natural refrigerants. This initiative is known as “Natural Five,” which refers to five types of natural refrigerants: ammonia (NH3), carbon dioxide (CO2), water (H2O), hydrocarbons (HC), and air (Air). These natural refrigerants are extensively used across a broad temperature range, from 200°C (392°F) to -100°C (-148°F), in applications such as heating, drying, hot water supply, air conditioning, refrigeration, and freezing.

Energy-Efficient Mayekawa Cooling Systems Gaining Popularity in Large Warehouses and Distribution Centers

Mayekawa's energy-efficient products, including the NH3/CO2 Cooling System and Thermo-shutter, are being increasingly adopted by customers across Thailand in large warehouses and distribution centers. These systems provide substantial energy-saving benefits while enhancing the efficiency of cooling system management. In addition, Mayekawa is supporting various projects to assist the business expansion of customers in Thailand and the broader ASEAN region, spanning multiple industries.

▲ Examples of Implementation

Through Mayekawa's unique innovations and advanced technologies, we not only help our customers achieve energy savings and cost reductions but also contribute to reducing greenhouse gas emissions and protecting the global environment.
