A condensing unit is the heat-rejection assembly of a refrigeration system — a compressor and a condenser packaged together, optionally with a liquid receiver and oil separator. It compresses refrigerant vapour and rejects heat to either air or water before sending liquid refrigerant to the evaporator.

Praj manufactures both air-cooled and water-cooled condensing units. Air-cooled units are simpler to install; water-cooled units are more energy-efficient in hot, humid Indian climates and at larger capacities. Compressor options: Copeland, Bitzer, Frascold.

FAQ

Frequently Asked Questions

What is the capacity range of Praj condensing units?

Air-cooled: 2 TR to 60 TR. Water-cooled: 10 TR to 500+ TR. Custom sizing for special applications.

Which compressor brands do you use?

Praj integrates Copeland (scroll & semi-hermetic), Bitzer (reciprocating & screw), and Frascold compressors. Brand chosen based on capacity, refrigerant and customer preference.

Which refrigerants are supported?

R404A, R22, R134a, R407C and ammonia. HFC blends for smaller commercial-scale units; ammonia for large industrial plants.

Should I choose air-cooled or water-cooled?

Up to 30 TR or in dry climates, air-cooled is usually sufficient. Above 30 TR or in hot/humid coastal climates, water-cooled is 15–25% more efficient.

What is the warranty?

12 months on the complete unit. Compressor warranty follows OEM (typically 12–24 months from manufacturer).

Do you provide installation and commissioning?

Yes. Praj engineers handle full site installation, pipework, electrical, refrigerant charging, leak test, vacuum, commissioning and customer training across India.
