It is a chiller unit combined with an inverter refrigeration system that controls operation with energy saving.
It is a chiller unit combined with an inverter refrigeration system that controls operation with energy saving.
New refrigerant R448A adopted! Inverter-equipped screw chiller unit.
The "iZFSB series" is a product that demonstrates exceptional energy-saving performance by controlling the refrigeration capacity continuously through inverter speed control, preventing excessive cooling. Additionally, by replacing the conventional piston valve unloading with inverter speed control, it allows for appropriate operation according to the load, enabling significant energy savings. It uses the new refrigerant R448A. 【Features】 ■ Outstanding energy-saving performance ■ Equipped with the advanced brain "iZ Monitor" *For more details, please refer to the PDF materials or feel free to contact us.
It is a quiet Peltier chiller unit with minimal vibration.
The Peltier-type compact chiller unit BCU is a quiet and low-vibration chiller unit that utilizes Peltier cooling. Please use it when precise temperature control is required for semiconductor manufacturing equipment and scientific instruments.
A low-temperature chiller unit that demonstrates high cost performance!
"Under3" is a low-temperature chiller unit that can consistently supply clean water at temperatures below 3°C, thanks to our chiller control technology. There is no temperature rise during the shutdown of the refrigeration unit, and unlike ice storage systems, there are no limitations on the amount of ice used, allowing for continuous supply. Additionally, by expanding existing facilities, it is possible to supply even lower temperature clean water at a high flow rate. [Features] ■ Stable supply of cold water below 3°C ■ Achieves high flow rates by expanding existing facilities ■ Can be used close to where cold water is needed ■ Stable supply ■ Energy-saving *For more details, please download the PDF or feel free to contact us.
Adopting R-717 refrigerant, which poses no environmental burden and thus has no concerns about future regulations due to the phase-out of fluorocarbons. The evaporative condenser method takes advantage of the characteristics of the refrigerant.
R-717 refrigerant is commonly used worldwide. In Japan, due to stricter safety regulations in the 1970s and subsidies for Freon, all manufacturers promoted the use of Freon. The Maekawa Manufacturing Group continued to provide services overseas, accumulating technology and human resources. In order to resume operations domestically in earnest, we focused particularly on improving safety technology and were able to start in 1990. As a result, we gained further recognition with the adoption of our systems for the ice skating rink and bobsleigh venue at the Nagano Olympics, and today, about 70% of our shipments continue to be R-717 refrigerant. Thanks to technological advancements, it has become possible to reduce the amount of refrigerant held from 1/10 to 1/50 without losing refrigeration capacity, compared to the methods used during the period when R-717 was considered dangerous in Japan. Not only do we have technology, but we also have a large number of experienced service personnel, from young to veteran, who are well-versed in handling R-717 refrigerant and are stationed nationwide, which is a unique feature of our company that others do not have.

![[Construction Achievements] Renewal of Heating and Cooling Heat Pump Chiller Unit](https://image.mono.ipros.com/public/product/image/ec8/2001039612/IPROS31037957605336937581.jpeg?w=280&h=280)
Significant improvement in airflow through inspection and maintenance of the air handling unit! Achieved restoration of original air conditioning capacity.
Inspection and maintenance of the air handling unit were conducted alongside the renovation of the air conditioning system. The 100-horsepower dedicated chiller unit and steam system have been updated to a heat pump chiller unit (100 horsepower), stopping the use of steam for heating. With the timing for updating the chiller unit, we have ceased the use of steam for heating operations and installed a chiller unit that can provide both cooling and heating, thereby reducing the rising costs of heavy oil usage and achieving energy savings with a newly installed chiller that has a high COP (coefficient of performance). 【Benefits of Implementation】 ■ Reduction in running costs ■ Improvement in air volume *For more details, please refer to the PDF document or feel free to contact us.
