Rising Global Temperatures: A Growing Challenge for Industry
The World Is Heating Up
According to the World Meteorological Organization (WMO), there is an 86% chance that at least one year between 2025 and 2029 will exceed 1.5°C above pre-industrial levels, with global temperatures projected to range between 1.2°C and 1.9°C above the 1850 – 1900 average. WMO also warn there is an 80% chance that at least one of the next five years will exceed 2024 as the warmest on record.
The global temperature is increasingly so. Imagine our city getting hotter year by year. Summers becoming unbearable and outdoor work becoming dangerous. These are not prediction, and it is happening now!
India: A Case Study in Climate Stress
India is currently grappling with one of its harshest summers in recent history. The India Meteorological Department (IMD) reported that February 2025 was the warmest since records began in 1901.
Barmer recorded its highest temperature for early April, reaching 45.6 °C. According to meteorological records, this was highest since 1998.
Churu, Rajasthan and Sirsa, Haryana recorded above 50 °C; Delhi records highest temperature at 49.9 °C; Daltonganj, Jharkhand recorded highest temperature in ten years at 47.5 °C; Odisha temperatures crosses 45 °C.
There are several areas seeing temperatures above 45°C, the heatwave has had a significant effect on industrial processes, agriculture, and public health.
The extreme heat had given a stress on our workers and machine, especially in those facilities are lacking with adequate cooling infrastructure.
The Hidden Victim: Air Compressors
As the ambient temperatures increased, so the operational challenges for sensitive equipment like air compressors increasing too. These machines highly sensitive to heat and also critical to industrial operations. Excessive heat will be triggering emergency shutdowns.
These failures not only damage equipment but will cause production downtime, financial losses, and safety risks for workers.
Why Compressors Stop in the Heat
The air compressor shutdown in high heat is because of the rise in internal unit temperature. One of the factors that effect on internal temperature is the ambient temperature. According to Gay-Lussac’s Law, when the volume of a gas remains constant, an increase in pressure will increase the temperature. Therefore, when an air compressor in a warm ambient air, the compressed discharge air becomes even hotter. The more heat will generate during compression tends to remain within the system and raising the internal temperature. The excessive temperature will create some risks include screw contact due to thermal expansion and motor overheating, which may trigger emergency shutdown or trip. To prevent such issues, high cooling performance is essential.
This is where KOBELION air compressors stand out.
KOBELION: Engineered for High Temperature Resistance
Even in India, where ambient temperatures reach 50°C, KOBELION compressors continue to operate reliably. This excellent heat resistance is the result of a globally engineered model designed for harsh conditions.
Key engineering features include:
Optimal Unit Layout for Maximum Performance
Maintaining the proper heat balance inside the unit is essential. Internal cooling efficiency is improved through internal layout optimization and airflow analysis. The improvement is ensured stable airflow even in the hot Indian summer. This also to ensure the stable operation and uninterrupted production for the factory.
Result: stable airflow even at 50°C.
Large Cooler & Turbo Fan
Cooler and fan are the main parts to control the heat. Hence, we increase the cooler capacity to handle the high ambient temperatures. We also optimise the turbo fan technology to generate minimal heat contributes to environmental resilience and improved overall energy efficiency.
Oil-Cooled Motor Cooling (New VS Models only)
KOBELION replace the traditional fan cooling with oil cooling to improve the cooling and resistance to unit condition changes.
These design choices give KOBELION an advantage even in high ambient temperatures.
Intake Temp: 52.2°C
Running at 100% Load
Discharge Temp: 91.3°C

Real-World Case Study
KOBELION’s resilience is not just on paper. It is proven! One of our customers has operated KOBELCO compressors for over eight years under intense heat and dusty conditions without a single issue.
“Reliable and Robust—That’s Why We Chose KOBELCO”
— Mr. Sanjay Singh, Factory Manager
Kansal Group is Manufacturer of Automotive Sheet Metal Parts and Welded Sub-assemblies. Coupled with rich domain knowledge in design, development and engineering. Kansal Group is manufacturing facilities of almost all types of Sheet Metal components.
“We chose KOBELCO for its solid Japanese engineering, durability, and reliability. Before installation, we had many issues due to high heat. Now, we’re fully satisfied with performance, even after 8 years of operation under intense heat and dusty conditions, there have been zero issues.
We were so satisfied with the first unit that we replaced two others from a competitor with KOBELCO units. Now, all compressors at our facility are KOBELCO.
We are also very satisfied with the after-sales service and will continue using KOBELCO for future expansions.” – Mr Sanjay Singh shared.

A big thank you for their trust and valuable feedback. This was a prove to KOBELION’s resilience in harsh real-world conditions.
The KOBELION Development Story - No Compromise at 50°C
Mr. Hamada
Developer of KOBELION V7
Across the global market, KOBELION has made significant progress in durability. Starting with the third-generation model, we completely redesigned the design to developing an oil-cooled motor and reconfiguring the internal layout to ensure operation in a high-temperature environment of 50°C.
The development process presented numerous challenges like unexpected issues that arose just before reaching our goals or trade-offs like improving airflow increases noise. But we never compromised on the idea that “49°C is enough.” As long as there are customers operating in a 50°C environment, we will keep pushing forward. This commitment defines our KCC philosophy and Monozukuri.
Ready to Future-Proof Your Factory
As global temperatures continue to rise, industries must have the way to overcome and ensure the stable operation and production. KOBELION air compressors show how thoughtful engineering and a commitment to quality can deliver reliability, even facing of high ambient temperature. For factories in Japan and beyond, this is more than a product, it is peace of mind.
