Low Environmental Impact

The Montreal Protocol phasing out R-22 incorporated HFCs as controlled substances under the Kigali Amendment in 2016. This sets the direction toward HFC phase-down on a global scale.

Since the Azanechiller uses ammonia, (R717) which has no Ozone Depleting or Global Warming characteristics, it represents a future proof solution immune to the uncertainty of furture HFC gas costs and availibility.

Naturally Efficient Refrigerant

Ammonia offers exceptional efficiencies across a wide range of operating conditions. For typical applications, ammonia offers a 20% improvement in performance compared with systems using HFCs.

Naturally Efficient Operation

The Azanechiller 2.0 range has set a new benchmark in chiller efficiency by integrating variable speed reciprocating compressor technology with EC fans, close evaporator approach design and advanced controls. Azanechiller 2.0 delivers efficiency that is at least 20% higher than competing HFC chiller technology.

Key energy efficient features include:

  • Use of ammonia in a flooded evaporator with a tight approach and negligible superheat
  • EC fan motors
  • Floating head pressure control
  • Floating suction pressure control
  • Minimal suction pressure drop
  • VFD driven reciprocating compressors
