OptiChill™ FreeCool

OptiChill FreeCool 750 – 1365kW

A low energy, low sound R134a air-cooled screw chiller with a large capacity to meet a range of cooling loads.

More than 95% free-cooling over a year
Save more than 50% of the energy consumed by a conventional chiller

Features

  • Over 200 models
  • Quiet and Extra Quiet ranges
  • Dual independent refrigeration circuits for resilience
  • Up to 95% free-cooling
  • 12.5°C increase in operational evaporating temperature range allowing supply water temperatures to be increased, thus raising the free cooling threshold and giving enhanced compressor efficiency and reduced power input
  • Latest fan technology reduces sound and power input
  • 8 stages of cooling for more precise capacity match
  • Large surface area condensing coils
  • High efficiency shell and tube evaporator
  • Large surface area condensing coils
  • High efficiency shell and tube evaporator
  • Free-cooling virtually all year round
  • Efficient shell and tube evaporator with freeze protection offers high evaporating temperatures
  • Large surface area condenser coil with enhanced tube and fin for improved heat exchange and low noise
  • Two sizes of free-cooling coil (2 and 3 rows) for increased annual efficiencies
  • Automatic rescheduling of chilled water
  • Economisers, each with dedicated EEV, to enhance compressor performance at full and part load operation

Options

  • Modem link for remote monitoring
  • Leak detection system for F Gas compliance
  • Corrosion-resistant condenser coils for aggressive atmospheres
  • Coil guards to help prevent fin damage
  • Condenser fan air discharge plenum – choice of two heights
  • Anti-vibration mounts
  • Low ambient kit for operation in ambients as low as -30°C
