About the Customer
Lakshmi Vacuum Technology Pvt. Ltd. is one of India’s trusted manufacturers of vacuum heat treatment furnaces, brazing furnaces, sintering systems, and high-temperature thermal processing equipment.
Their machines are used in industries like aerospace, automotive, tooling, medical implants, and defence—where precision and reliability are non-negotiable.
Because their products involve high-temperature heating, their factory and machine surroundings naturally experience very high ambient heat.
Customer’s Challenges
1. High Ambient Temperature in Production Area
The furnaces operate continuously at extreme temperatures.
This leads to:
-
Electrical panels heating up quickly
-
Frequent component tripping
-
Reduced life of electronics
-
Need for stable cooling even during peak heat load
Standard panel ACs cannot handle such harsh temperature conditions.
Lakshmi Vacuum required a cooling solution that would perform reliably in high-ambient environments.
2. Export Requirements – 60 Hz Power Supply
Lakshmi Vacuum exports a major portion of their furnaces globally (US, Europe, Middle East, etc.).
Most export countries use 60 Hz power supply, while India uses 50 Hz.
They needed a panel AC that:
-
Works on both 50 Hz and 60 Hz
-
Performs without derating or modification
-
Allows them to ship the same furnace design worldwide
This avoids redesigning electrical systems for each country and saves engineering time.
3. Need for a Consistent OEM Partner
Since furnaces require panel cooling in every model, Lakshmi Vacuum needed a reliable OEM supplier who could support:
-
Continuous supply
-
Consistent quality
-
Fast technical support
-
Easy serviceability
-
Long-term product stability
They wanted a partner—not just a vendor.
