UTW - 38/A
The patented Coolsure UTW is a High Efficiency AC/DC cooling system, ideally suited for telecom access nodes and other small equipment rooms.
Equipped with innovative features and high performance components,
Coolsure UTW air conditioners use less than half the energy of typical comfort
and precision air conditioning systems, in a package that can be deployed
as a direct replacement for standard window units.
Coolsure UTW air conditioners offer the ultimate in cooling availability for critical telecom sites. The double-conversion DC inverter topology permits an ultra-wide input voltage and frequency range, allowing unaffected cooling operation in unstable AC mains conditions. In areas prone to complete AC mains failure, UTW can be powered efficiently from the 48V telecom backup battery via optional BCU4818 DC/DC converter, providing uninterruptible cooling and maintaining network integrity.
The BLDC fan and compressor are operated at variable speeds eliminating the stresses of on/off regulation and extending the life of all major components. Coolsure’s patented control technology features dynamic load sharing and a sophisticated maintenance alarm system, as well as supporting N+1 redundant configurations to prevent system failure caused by unit faults.
Unlike alternative cooling solutions, such as free venting and heatexchangers, Coolsure UTW air conditioners allow operators in warm climates to substantially reduce their carbon footprint without compromising on the reliability and life of the critical telecom equipment and batteries.
