🏢 Company Overview

Parameter	Details
Founded	2017
Industry	Heat Exchangers & Refrigeration Components
Products	Condenser coils, evaporator coils, micro-channel heat exchangers
End Markets	HVAC, air conditioners, refrigeration, data centres
Manufacturing	India (export-oriented capability)
Business Type	B2B manufacturing (OEM supplier)

KRN is not a consumer brand.
It is a component supplier to large OEMs in cooling and refrigeration.

This makes it:

Less dependent on retail demand
More dependent on industrial and infrastructure growth

⚙️ What Exactly Does KRN Manufacture?

Understanding the product is key.

🔹 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:

Split ACs
Commercial HVAC systems
Chillers
Cold storage units
Industrial cooling
Data centre cooling

🔹 2️⃣ Micro-Channel Heat Exchangers (High-Value Segment)

This is the most important part of KRN’s future.

Micro-channel exchangers:

Use aluminium instead of copper
Are lighter
More energy efficient
Cheaper at scale
Environment-friendly

Most global HVAC OEMs are shifting from copper to aluminium micro-channels.

This is a structural industry shift, not a temporary trend.

🔹 3️⃣ Refrigeration Coils & Assemblies

Used in:

Cold chains
Food storage
Pharmaceutical logistics
Supermarkets
Industrial refrigeration

As India builds more cold storage and pharma infrastructure, this demand grows.

🧩 Business Model – How KRN Makes Money

KRN follows a B2B OEM-supplier model.

Step-by-step flow:

HVAC / refrigeration OEM gives design & specs
KRN manufactures heat exchanger components
Supplies in bulk on long-term contracts
Revenue comes from volume + value addition

🔹 Key Business Characteristics

✔ Repeat orders
✔ Long client relationships
✔ High switching cost for OEMs
✔ Volume-driven growth
✔ No marketing expense

Once a supplier is approved by an OEM, replacement risk is very low.

🌍 End-Market Demand Drivers (Very Important)

KRN’s growth depends on cooling demand, not just AC sales.

🚀 1️⃣ Rising Air-Conditioner Penetration

India’s AC penetration is still below 10%.

As incomes rise:

Residential AC demand rises
Commercial HVAC demand explodes

Every AC = heat exchanger demand.

🚀 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:

Food storage
Vaccine logistics
Pharma cold chains

All require industrial refrigeration.

🚀 4️⃣ Energy Efficiency Regulations

Governments globally are pushing:

Lower power consumption
Eco-friendly cooling

Micro-channel exchangers fit perfectly here.

🧱 Competitive Moat – Why KRN Has an Edge

⭐ 1️⃣ Technical Know-How

Heat exchangers are not commodity products.

They require:

Precision engineering
Thermal design capability
Metallurgical expertise
Quality consistency

Entry barriers are higher than they look.

⭐ 2️⃣ OEM Approval Barrier

Getting approved as a supplier:

Takes years
Requires audits
Requires performance testing

Once approved → very sticky relationship.

⭐ 3️⃣ Shift to Aluminium Micro-Channel

KRN is positioned in a structural transition segment:
Copper → Aluminium

Not all players can adapt quickly.

⭐ 4️⃣ Asset-Efficient Manufacturing

Compared to heavy engineering:

Lower capex
Faster capacity addition
Better scalability

⭐ 5️⃣ Export & Global Opportunity

Global HVAC OEMs are diversifying supply chains away from China.
Indian suppliers like KRN benefit from this China+1 strategy.

📊 Financial & Operational Characteristics (Conceptual View)

(Exact numbers aside, understand the nature)

Revenue growth driven by volume expansion
Margins improve with scale
Working capital required but manageable
No customer concentration ideally (over time)
Capex linked to capacity expansion

This is a classic manufacturing scale-up story, not a trading stock.

🧑‍💼 Management Philosophy

KRN management focuses on:

Capacity expansion
Product up-gradation
Long-term OEM relationships
Export readiness

The mindset is engineering-first, not marketing-first.

⚠️ Risks You Must Understand

No business is perfect.

⚠️ 1️⃣ Customer Concentration Risk

If revenue depends on a few OEMs, bargaining power can reduce margins.

⚠️ 2️⃣ Commodity Price Risk

Aluminium & copper price fluctuations can impact margins.

⚠️ 3️⃣ Cyclical Demand

HVAC demand can slow during economic downturns.

⚠️ 4️⃣ Technology Change Risk

If a new cooling technology emerges, constant up-gradation is required.

⚠️ 5️⃣ Scale Execution Risk

Rapid capacity expansion must be executed carefully.

These are manageable risks, but investors must be aware.

🔍 Where KRN Fits in the Value Chain

Layer	Example
Raw Materials	Aluminium, copper
Component Supplier	KRN Heat Exchanger
OEM	AC / HVAC / refrigeration brands
End User	Homes, offices, data centres

KRN sits in the middle layer, which often has the best risk-reward.

🔮 Long-Term Growth Outlook (2025–2035)

🔹 Structural tailwinds:

AC penetration growth
Data centre infrastructure
Cold chain expansion
Energy efficiency norms
Export opportunity

🔹 Company-specific levers:

Capacity expansion
Higher value micro-channel products
New OEM tie-ups
Export growth

If executed well, KRN can evolve from:

Component supplier → strategic cooling solutions partner
