GERMANY: A further development of Roller’s DLK series of air coolers sees the introduction of new units for use with CO2.
The DLK Next air coolers for applications up to 80bar expand the performance range of optimised evaporators with reduced tube volume for CO2 applications.
Special attention has been paid to installation flexibility with the new coolers. This includes an easy-to-install aluminium housing with practical and generously dimensioned cutout options to meet the diverse requirements of installation engineering. This is complemented by flush ceiling suspension brackets made of stainless steel.
The evaporator blocks are available with 4 and 6 rows of tubes, accompanied by correspondingly large heat exchanger surfaces. For deep-freeze applications, the units are offered in T-design with electric defrosting systems in block and tray.
The DLK Next offers a pre-installed electronic expansion valve with precise superheat control settings for 40 refrigerants, including CO2.
Available in sizes up to 14kW cooling capacity, the new DLK Next is equipped with 1 to 4 high-efficiency EC fans as standard. Roller says it will eventually replace the DLK/T…EP (Euroline Plus) units.
