Mini Cooler
HIGH PERFORMANCE AIR CONDITIONING
Mini Cooler is the indoor package air conditioner,
direct expansion with built-in air cooled condenser
especially designed for telecommunications sites in
cabinet and enclosure (e.g. BTS and other technological environments).
Energy Saving And Cost Effective Cooling
The most modern design and components such as scroll compressor, plug-type fans and the freecooling mode assure high
energy saving and greatly reduce running and lifetime cost.
High Power Density Rate
Faster Start-Up
More and more applications in modern telecommunications
networks are based on small enclosures with an increasing
need for reduced dimensions but with high data process intensity. Mini Cooler is the answer to the need of providing high
refrigerating power in a small environment with up to 5 kW
cooling capacity and a 310x620x1595 mm (WxDxH) frame.
The cooling circuit is pre-charged, fine tuned and fully tested
before delivery. No pressure test is required on site. Installation
is speeded up by using the fast-plug electrical connections (on
request) and the automatic commissioning software: installation and commissioning are completed in less than 25 mins
without need of specialized personnel on site.
High Reliability
Dedicated Accessories
Evaporator fan, damper and control are powered by 48VDC
emergency power sources in case of mains failure. Continued
ventilation and the optional maximised freecooling assure
constant operation of the telecommunications equipment and
continued revenue from the site. The 48VDC supply increases
the lifetime and reliability of the microprocessor and unit.
Mount the especially designed plenum to optimise condensing airflow in the direct expansion mode and reduce the
noise level. It prevents any airflow short circuit in the freecooling mode and any water intrusion.
