Dunham-Bush has launched a new chiller series to cater for high ambient region. The new HELIOS series air-cooled horizontal screw compressor – ACHX-BHVD, designed with inverter compressors and variable speed fans, is 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 419RT (432 to 1472kW)

• Environmentally Friendly Refrigerant

Refrigerant R134a (Non-toxic, Not flammable and Zero ODP)

• High Ambient Application Compressor

Semi-hermetic variable speed horizontal screw compressors with superior part load performance

• Variable Speed Condenser Fans

VFD condenser fans to optimized part load performance and provide better unit IPLV

• Enhanced Heat Exchanger

All Aluminum Micro-Channel (MCHX) condenser with TCP-Coating for corrosion resistance. (Optional Fin and Tube Condenser)

• Independent Circuits

Single/Twin 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 1250F (520C) ambient temperature
