Chillers Products

Overview

An air cooled R410A scroll chiller offering a free cooling variant and a wide span of cooling capacities from 110 to 1010kW. Extremely energy efficient and compact, the DeltaChill™ (DCC) combines quiet, cost effective scroll compressors and the latest fan technology applied in a modular V-frame coil design. In higher capacity models and across all free cooling models, microchannel heat exchangers lift efficiency even higher, whilst still minimising space claim.

Choose from 282 models

A huge range of models provides exceptional flexibility, tailored exactly to your application allowing unit selection to be optimised for efficiency or footprint.

Reducing operating costs and carbon footprint

By selecting the DeltaChill™, you are investing in a chiller that significantly reduces running costs and carbon footprint. The 140 – 1010kW DeltaChill™ FreeCool (DCF) spends up to 95% of the year in free-cooling. During any mechanical cooling, the DeltaChill™ has excellent part load efficiencies, ensuring no power is wasted. Typically in cooling applications, load conditions dictate that a chiller only operates at full load for 3% of the year.

Units within this range are Ecodesign compliant for both process (SEPR) and comfort cooling (SSCEE) applications. Please refer to the technical manual, website, or your Airedale account manager for full details

Features & Benefits

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)
