🔹 1️⃣ Heat Exchangers (Core Product)

Heat exchangers are devices that transfer heat from one medium to another.

In simple words:

• AC cools your room
• Heat exchanger throws that heat outside

KRN manufactures:

• Condenser coils
• Evaporator coils
• Micro-channel heat exchangers

These are used in:

🚀 2️⃣ Data Centres Boom

Data centres need:

• 24×7 cooling
• High-efficiency heat exchangers

India is becoming a major data centre hub → long-term tailwind.

---

🚀 3️⃣ Cold Chain & Pharma Growth

India is investing heavily in:
