DeltaChill™ & DeltaChill™ FreeCool

Efficiency

• ESEER up to 4.88
• Up to 38% more cooling k W/m² than previous generation compact free cooling chiller
• Free cooling models spend up to 95% of the year in free cooling
• Microchannel coils reduce life cysle costs and reduce footprint

Flexibility

• Single, dual or triple independent refrigeration circuits allowing 2-9 stages of cooling
• Modula ‘V’-frame coil fan arrangement for improved part load performance and control
• Easy access to components

Operational Costs

• Models up to 450kW included on the Energy Technology List (remaining models pending), offering potential for 100% first year capital allowance
• Free cooling at up to 109% of nominal capacity for reduced operating costs and carbon footprint
• Virtually entire range contributes to a building achieving an additional 2 BREEAM points

Quality / Reliability

• Single and standby pumps for resilience

• Large surface area, corrosion-resistant condenser coils for enhanced heat exchange

Features

• 110 – 980kW (DCC) and 140 – 1010kW (DCF) nominal cooling capacities
• 151 models (DCC) and 131 models (DCF)
• Optimised for R410A which only requires a minimum refrigerant charge and has a high heat transfer coefficient
• Low sound ranges: Quiet (R) and Extra Quiet (X)
• Sequenced scroll compressors minimise sound and allow capacity to more precisely match the application
• Electronic Expansion Valves increase ESEER by 30%
• Optional head pressure set point management achieving optimum EER

Options

• EC fans – increasing ESEER to 4.88
• High airflow EC fans (DCF Quiet models)
• Variable supply water temperature control to save power and raise the free cooling threshold
• Leak detection system for F Gas compliance
• Automatic refrigerant pump down in the event of a refrigerant leak, which together with leak detection, qualifies the DeltaChill™ for one BREEAM point
• Compressor enclosure minimising sound
• Low ambient kit for use in ambient temperatures as low as -30°C (model dependent)
