COOLING
Features and advantages
■■ Eighteen sizes with nominal cooling capacities from 345
to 4652 kW.
■■ The 16NK absorption chillers are designed for cooling
applications where low-pressure steam is available as
waste heat.
■■ Can tie into district steam systems.
■■ Allows diversification of critical cooling requirements.
Critical cooling loads are met with minimal electrical
power input.
■■ Allows use of smaller emergency generators since the
electrical load associated with an absorption chiller is
minimal.
■■ Environmentally balanced and CFC-free.
■■ Minimises global warming effect by greatly reducing
power consumption and eliminating the generation of
greenhouse gases.
■■ Reduced noise and vibration levels. The absorption chiller
does not use a large motor-compressor, leading to quiet,
vibration-free operation.
■■ Small footprint. The high efficiency associated with
double-effect chillers results in a reduction of the required
installation space.
■■ Auto-diagnosis system monitors operating conditions,
predicts chiller information and maintains stable operation.
■■ Advanced high-precision control system.
■■ Absorption pump with inverter control for efficient,
energy-saving operation.
■■ High-performance purge system minimises maintenance
requirements.
■■ State-of-the-art protection devices guarantee enhanced
operating safety.
