Simplified Ownership and Operation for Efficiency

We efficiently manage advanced technologies like a variable-speed drive compressor, energy-optimized hybrid cooling, and expertly designed air-to-liquid free cooling coils to maximize year-round efficiency.

Efficiency

Hybrid mode combines the best technologies to boost part-load efficiency.

Simplicity

Packaged controls and single-point convenience simplify operation.

Reliability

Get assured performance from the variable-speed leaders who have over three generations of expertise.

Fast Payback

Payback possible in as little as two years – and we can prove it.

Features

  • Packaged controls for single-point convenience to easily accommodate process or building changes
  • Variable-frequency inverter technology enables a zero-inrush soft start and a high-displacement power factor across the entire operating range
  • Performance is assured by AHRI certification, the first for an air-cooled screw chiller with free-cooling
  • Open-loop and closed-loop design solutions for different building systems
  • Intelligent controls also optimize the balance between using fans to move air over the free-cooling coils
  • Quick Start option achieves full load after a power loss in four minutes or less
  • Integrated air-to-liquid, free-cooling coils, designed by our heat transfer experts, reduce or eliminate the need for mechanical cooling when conditions allow
  • 115-500 TR, 400-1750 kW

Quick Start

YVAA chillers quickly restart in only 34 seconds after a power outage, thanks to their Quick Start feature and variable-speed drive. This allows all compressors to start simultaneously, ensuring a swift return to full capacity compared to standard chillers taking up to 10 minutes.

Hybrid Mode Technology

Traditional free-cooling chillers with fixed-speed compressors save energy only during compressor shutdown in very cold weather. Johnson Controls Arabia introduces Hybrid Mode, optimizing year-round energy use. Using free-cooling coils to reduce mechanical cooling at higher temperatures, VSD compressors enhance long-term performance and efficiency.

Free-cooling Technology

YVFA air-cooled chillers excel with high leaving water temperatures, maximizing capacity in a compact design. Intelligent control valves save pump energy when free-cooling isn't required, and the chiller seamlessly switches modes to save energy.
