Power Efficient Chillers

Overview

While BROAD India is globally renowned for non-electric absorption chillers, we recognize that some facilities require ultra-high-efficiency electric cooling. Our Power Efficient Chiller line utilises advanced magnetic-bearing, oil-free centrifugal compressor technology to deliver the highest Coefficient of Performance (COP) available in the commercial HVAC market - reaching up to 11 under part-load conditions.

By eliminating the oil management system entirely, these chillers remove the single biggest cause of efficiency degradation in conventional electric chillers: oil coating the heat exchange tubes. The result is a cooling system that maintains its day-one efficiency year after year, operates with whisper-quiet acoustics, and significantly reduces ongoing maintenance requirements.

Frequently Asked Questions

Why is 'oil-free' operation so important for chiller efficiency?
In conventional chillers, lubricating oil inevitably mixes with the refrigerant and circulates through the system. Over time, this oil coats the copper tubes in the heat exchangers, acting as an insulator. Even a thin layer of oil can reduce heat transfer efficiency by 10-15%. By completely eliminating oil, magnetic-bearing chillers maintain their original 'day-one' efficiency for the entire life of the equipment.
How does the part-load efficiency compare to conventional chillers?
It is significantly better. Most commercial buildings operate at partial cooling loads (40-70% capacity) for over 90% of the year. Magnetic-bearing chillers use an integrated Variable Frequency Drive (VFD) to slow down the compressor at partial loads. Because there is no mechanical friction, the compressor remains incredibly efficient at low speeds, achieving Integrated Part Load Value (IPLV) COPs of 9 to 11, compared to 5 to 6 for standard chillers.
Are magnetic-bearing chillers more expensive to maintain?
No, they are actually much cheaper to maintain. Conventional chillers require regular oil analysis, oil changes, oil filter replacements, and eventually, expensive mechanical bearing replacements. A magnetic-bearing compressor has no oil management system and no physical wear on the bearings, virtually eliminating mechanical maintenance.
