CACA Coolers with or without Tube Axial Fan:-
CACA Coolers (Closed Air Circuit Air Coolers)
We manufacture highly efficient CACA Coolers, engineered to provide closed-loop air-to-air cooling for large rotating machines such as motors, generators, and transformers. These coolers are ideal where external cooling water is not available, and internal air needs to be cooled using ambient air through forced convection.
Available in both variants — with or without Tube Axial Fans — our coolers offer a reliable and self-contained cooling solution tailored to diverse industrial environments.
Technical Highlights:-
- Closed air circuit design with internal recirculating hot air and external ambient air separation
- Plain tube or optional finned tube configuration based on cooling requirements
- Designed for horizontal or vertical mounting
- Optionally integrated Tube Axial Fans for forced-draft ambient air cooling
- Crimped fin tube configuration for improved heat dissipation
- Air guide vanes and baffles for controlled airflow direction
- Compact and rugged casing construction using fabricated steel
- Filter mounting frames (optional) for dust-prone installations
Optional Features:-
- With Tube Axial Fan:-
- Integrated fan mounted externally or internally
- Pre-wired and factory-assembled fan unit with motor and grill
- Designed for forced air convection to improve ambient heat rejection
- Without Tube Axial Fan:
- Suitable for natural convection or externally ducted air systems
- Cost-effective solution where forced air is not required
Manufacturing Process:-
- Precision fabrication of tube sheets, casing, and water boxes
- Assembly of finned tube bundles and housings
- Tube expansion using roller expansion machines
- In-house painting, inspection, and hydro testing
- Fan integration and electrical pre-wiring (for fan-equipped models)
- Final assembly with protective packaging and identification tagging
Quality Assurance & Testing:-
- Designed as per ASME, TEMA, and project-specific standards
- Mock-up testing for tube expansion process
- Fin bonding tests to ensure heat transfer integrity
- Hydrostatic pressure testing (if applicable to design)
- Fan performance and electrical tests (for fan-equipped units)
- Complete documentation, drawings, and test certificates
Applications:-
- Electric Motors & Generators (self-cooled or ventilated enclosures) Transformers
- Transformers
- Hydro & Thermal Power Stations
- Industrial Air-Cooled Enclosures
- High-Altitude or Waterless Cooling Installations
