Dunham-Bush has extended HELIOS series air-cooled horizontal screw compressor – ACHX-BHVD from 420TR to 590TR, making it one of the largest capacity range air-cooled chiller series in the market. This chiller series was designed based on Middle East region requirement and able to deliver optimum performance and superior part load efficiency at high ambient environment.

Some of the features include: –

• Wide Capacity Range

Nominal cooling capacity range from 123 to 590RT (432 to 2073kW)

• Environmentally Friendly Refrigerant

Refrigerant R134a (Non-toxic, Non-flammable and Zero ODP)

• High Ambient Application Compressor

Semi-hermetic variable speed horizontal screw compressors
optimized for high ambient application and superior part load
performance

• Variable Speed Condenser Fans

VFD condenser fans to optimize part load performance and lower
noise operation.

• Enhanced Heat Exchanger

All aluminum Micro-Channel (MCHX) condenser with TCP-coating for
corrosion resistance. (Optional enhanced E-coating protection and
finned tube type condenser)

• Independent Circuits

Multiple Compressors with independent circuits for redundancy and
reliability

• User-Friendly Controller

Easy to operate DB Vision controller with electronic expansion valve
(EEV), to provide superior capacity control and stability

• Excellent Efficiency

AHRI certified and meets/exceeds ASHRAE 90.1 standard

• Designed for High Ambient Environment

Able to operate up to 125 0 F (52 0 C) ambient temperature
