Moreover, their oil-free design, coupled with the utilization of R134a, an eco-friendly HFC refrigerant, further minimizes emissions, offering an environmentally conscious alternative to harmful refrigerants while promoting sustainability goals.
Energy Efficiency and Operational Sustainability:
Step into the realm of Energy Efficiency and Operational Sustainability, where innovation and eco-conscious practices are reshaping the landscape of buildings and factories. At the heart of this transformation lies the oil-free chiller, a key player in improving energy efficiency and promoting sustainability. Join us as we delve into the impactful role of oil-free chillers in paving the way towards a greener future for both infrastructure and industrial sectors.
Explore Our Compressor
Danfoss Turbocor Compressor
Explore the cutting-edge cooling technology of the Danfoss Turbocor Compressor within the BROAD Oil-Free Chiller. Boasting noise levels below 65 dBA, a multi-compressor system, and exceptional efficiency, this breakthrough guarantees optimal performance while reducing maintenance requirements by 90%. Setting new benchmarks in quiet, efficient, and low-maintenance cooling solutions.
Inverter-Controlled Centrifugal Compressor
The inverter-controlled centrifugal compressor, equipped with an integrated driving module, dynamically adjusts its speed according to fluctuating conditions like decreased condensing temperature or varying load. This adaptability maximizes energy efficiency across the 10-100% range of the rated load, ensuring consistent and effective performance.
Frictionless System
The digital magnetic bearing system operates seamlessly throughout compressor runtime, while its oil-free components prevent the buildup of an oil film on heat exchanger pipes, maintaining peak efficiency. This ensures the chiller’s reliability, consistency, and exceptional performance over its operational lifespan. Unlike traditional chillers with 9% oil content, which can lead to a 15-20% efficiency decrease, the BROAD Oil-Free Chiller enhances efficiency by over 15% thanks to its innovative oil-free lubrication system.
Our Advanced Oil-Free Chiller Technology
Electronic Expansion Valve:
The electronic expansion valve precisely controls the injection of liquid refrigerant into the evaporator, optimizing efficiency by managing compressor, evaporator, and condenser operations. This sophisticated system enhances efficiency by finely regulating refrigeration components.
Low Start-up Current Ampere:
Enabled by magnetic bearing technology, the BROAD Oil-Free Chiller’s compact impeller requires a minimal 2A current for start-up, minimizing disruption to the electrical grid. This is a stark contrast to conventional chillers, which may demand a substantial 1500A start current.
Low Consumption, High IPLV & COP:
While various chillers boast different Integrated Part Load Value (IPLV) ratings, with screw chillers typically ranging from 0.6-0.7 kW/TR and centrifugal chillers from 0.65-0.75 kW/TR, BROAD sets itself apart with an exceptionally low 0.34-0.37 kW/TR.
| Cooling Capacity (TR) | Energy Consumption (kW) | COP (kW/TR) | |
| High | 1401.84 | 503.8 | 0.359 |
| Low | 1211.76 | 647.5 | 0.534 |
| Average | 1156.59 | 553.26 | 0.478 |
The BROAD Oil-Free Chiller achieves an outstanding Integrated Part Load Value (IPLV) of 11.5 (according to AHRI standards), resulting in a remarkable 40% reduction in energy consumption compared to conventional electric chillers.
Saving & Maintenance Features of BROAD Oil Free Chiller
Turbocor Compressor Saving
In traditional compressors, a bearing supports the shaft, necessitating frequent maintenance. However, the Danfoss Turbocor compressor utilizes magnetic levitation, eliminating the need for bearings altogether. This innovative design requires no lubrication, thus eliminating the risk of refrigerant pollution and deration, leading to substantial savings on both maintenance and operational expenses.
Maintenance Cost Saving
BROAD Chillers incorporate top-tier components with extended lifespans, exceeding those of other brands. This translates to nearly 90% savings on maintenance costs compared to conventional electric chillers. Furthermore, since these chillers operate without oil, the savings are even more significant, as illustrated in the table below.
Space Saving
Unlike traditional electric chillers, BROAD packaged chillers offer a more compact design, boasting a reduction in size and weight by 30-50%. Featuring outdoor-friendly BROAD pump sets and stainless-steel enclosures, they are ideal for outdoor installation. This not only conserves space in mechanical rooms but also streamlines the installation process, ultimately reducing land and labor costs.
Our Facility for Customers
Online Monitoring & Localized Services
Since 1996, BROAD has provided complimentary online remote monitoring, fault alerts, and performance tracking for the entire lifespan of the chiller, up to 30 years. Additionally, we offer a dedicated local service team available to assist customers with any issues that may arise. As part of our commitment to quality service, we conduct annual checks on the customer’s chiller to ensure optimal performance year after year.
