About Us | Aircon Cooling Coils & Heat Exchangers

Who We Are

Pioneers in Heavy-Duty Heat Transfer Technology

Founded with a clear vision to bridge the gap between theoretical thermal design and durable shop-floor fabrication, Aircon Cooling Coils & Heat Exchangers has grown into an acknowledged Indian manufacturing leader.

We specialize in bespoke engineered fin & tube cooling coils, heavy shell & tube heat exchangers, and dry cooler systems for continuous-duty industrial applications. Unlike standard off-the-shelf catalogues, our engineering team designs every heat exchanger around the client's actual operating fluids, temperature curves, fouling allowances, and spatial constraints.

Our Mission

To engineer zero-defect thermal exchange solutions that maximize thermodynamic efficiency and eliminate plant shutdown risks.

Our Vision

To be the most dependable global partner for HVAC OEMs and process industries, delivering certified performance with sustainable lifecycle value.

In-House Capabilities

Modern Manufacturing Machinery

Everything under one roof: from precision fin stamping to CNC expansion and automated welding, eliminating sub-contractor delays and ensuring uncompromised quality.

High-Speed Fin Press Line

Equipped with precision multi-row progressive dies producing corrugated, sine-wave, and louvered fin geometries with self-spacing collar heights for consistent airflow distribution.

CNC Hairpin & Return Benders

Fully automatic CNC benders that form seamless copper and stainless steel hairpin tubes without wall-thinning or ovality at the bend radius, maintaining maximum burst pressure.

Vertical Hydraulic Tube Expanders

Multi-rod hydraulic bullet expanders that uniformly expand tubes over their entire finned length, ensuring 100% primary-to-secondary thermal conduction without tube distortion.

Orbital TIG & Induction Brazing

Header joints and distributor circuits are brazed under an inert nitrogen blanket by ASME Section IX qualified welders, eliminating internal carbon scaling and oxidation.

Underwater Hydro Testing Tanks

Deep illuminated water testing tanks where coils are pressurized with dry nitrogen up to 450 PSI (32 Bar) to detect the smallest pinhole bubble leaks across every single tube circuit.

Helium Mass Spectrometer Leak Test

State-of-the-art helium sniffer testing capable of identifying micro-leak rates as low as 1×10⁻⁶ mbar·l/s, providing absolute confidence for expensive refrigerant circuits.

Engineering Integrity

Designed for Real Operating Conditions, Not Generic Theories

In industrial HVAC and process heat exchange, failure is never an option. An undersized coil results in inadequate chilling or freezing, while an inferior expansion bond degrades efficiency rapidly within months.

At Aircon Cooling Coils, our thermodynamic engineers evaluate:

Sensible vs Latent Heat Ratios: Sizing row depth to prevent room condensation while maintaining air velocity below moisture carryover threshold.
Waterside Pressure Drop (WPD): Optimizing parallel circuiting to balance water velocity (between 3 to 6 FPS) and prevent erosion or air binding.
Fouling Factor Allowance: Incorporating adequate surface margin tailored to industrial air quality and process fluids.
