Introduction - Trane CGAX/CXAX Manual

Introduction

Trane is a leader in the air-cooled chillers marketplace,
thanks to excellence in design and manufacturing.
This tradition of excellence is present in the Conquest
air-cooled scroll compressor chillers range, a new
generation of chillers and heat pumps, providing
capacities from 42-160 kW.
Trane Quality
Trane is the designer and manufacturer of the core
components applying modern market standards
of quality in the fi nishing, a rigourous testing and
manufacturing plan, a powerful service portfolio
supporting the life cycle of the equipment.
Useful Effi ciency
The cooling only chillers, model CGAX, are rated Class B
(EER at full load at Eurovent conditions) and optimized
for operation at seasonal part load effi ciency (ESEER)
to maximize energy savings during real life building
demand, across all seasons.
The heat pump version, model CXAX, has been
optimized in the same way. Full Load COP is class B
as per Eurovent standard as well, while the part load
effi ciency ratio SCOP is compliant with Ecodesign
directive.

Acoustic Package
Two acoustical package options are available:
• Standard Noise (SN), with an average sound power of
Lw 86 dB(A)
• Low Noise (LN), for sensitive environments with a
sound reduction of an additional -6 dB(A)
The acoustical package does not bring any degradation
on the performances: cooling capacity, operating map,
or effi ciency.
Smart Chillers
• The operating map of the chiller, allows in cooling
mode, operation between -18°C up to 46°C ambient air
temperature.
• In heating mode, CXAX units can deliver 40°C hot
water, down to -15°C ambient air temperature.
• For industrial applications, with evaporator leaving
water temperature down to -12°C is Ecodesign
compliant (SEPR medium temperature > 2,8).
• The low profi le of the Conquest units allows easy
integration in buildings, thanks to the 1,5 m of height
on most of the units.
• A plug & play integration is supported by the option of
Hydraulic Module (with or without buffer tank).
• Chillers are provided with a Smart Controller and
a new generation interface, the Deluxe Touch Display.
• Full integrability capability thanks to available
communication protocols: Modbus, BACnet, LonTalk
and Trane BMS.
