── What We Offer

CHILLER TYPES WE INSTALL

Air-Cooled Screw Chillers

Factory-assembled, minimal water infrastructure required. 50TR to 1,200TR. Ideal for commercial offices, hospitals, and industrial buildings where cooling towers are impractical.
 

Water-Cooled Centrifugal

Highest efficiency for large-scale plants. 500TR to 5,000TR. Magnetic-bearing oil-free centrifugal compressors achieving 0.55 kW/TR — best-in-class for data centres and campuses.
 

Modular Packaged Chillers

Plug-and-play modular units from 20TR that can be combined for redundancy without a dedicated plant room. Rapid deployment for fast-track projects.
 
 

VSD Inverter Chillers

Variable speed drive compressors reduce energy consumption at part-load by up to 40%. Essential for buildings with variable occupancy profiles like hotels and offices.
 
 

Heat Recovery Chillers

Simultaneous chilling and heat recovery for domestic hot water, pre-heating, or process heating. Dramatically reduces overall site energy consumption.

Free Cooling Chillers

Economiser coils allow near-zero-energy operation during cool ambient conditions — ideal for data centres and 24/7 process cooling in North & Central India winters.

── FAQ

COMMON QUESTIONS

Air-cooled chillers are simpler and lower-cost to install, but less efficient and louder. Water-cooled chillers are more efficient and quieter, but require a cooling tower, water treatment system, and more plant room space. For large buildings above 500TR, water-cooled usually gives better lifetime value. We provide a comparative analysis as part of our feasibility study.
 
Modern magnetic-bearing centrifugal chillers achieve 0.15–0.55 kW/TR at full load, compared to 0.7–1.1 kW/TR for older reciprocating or screw chillers. Integrated part-load value (IPLV) is often a more meaningful metric — we provide IPLV calculations for every project.
 
 
A 200–500TR air-cooled chiller installation typically takes 8–12 weeks from order placement. A large water-cooled central plant (1,000TR+) with custom pipework and BMS integration typically takes 16–24 weeks. We provide a detailed programme at tender stage.
 
 
 
Yes. All our chiller projects come with a 12-month defects liability period and an optional Annual Maintenance Contract (AMC) with 99.9% uptime SLA and 24/7 emergency response.
