Kaltra reveals the new UltraCompact II product line
Press Release (ePRNews.com) - Nuremberg, Germany - Oct 10, 2017 - As a part of its long-term product development roadmap, Kaltra Innovativtechnik introduces the next generation of its UltraCompact product line. This series covers the cooling duty range between 50 and 300kW with the capacity steps of 25kW and provides total or partial heat recovery in a compact machine design and suited for air-cooled applications across many industries.
Powered by scroll compressors, the units deliver best-in-class energy efficiency with average EER of 3.35 thank to innovations in heat exchanging technology deployed by Kaltra.
Kaltra has deployed a number of innovations, including advanced microchannel condensers which help to cut down the condensing temperatures, and brazed all-aluminium corrugated plate evaporators that enable higher evaporation temperatures. The synergy effect promotes significantly higher overall efficiency with EER of up to 3.50.
Additionally, the new UltraCompact II lineup includes a solution for direct evaporative cooling with pads and integrated water distribution system. Kaltra collaborates with many customers located in hot climate zones, and the new evaporative water cooling solution will provide them significant savings.
The evaporative media are made of non-organic aluminum fins with an anticorrosion coating. The fin technology is a combination of a special finned structure and water-retaining coating, designed to keep pressure drop at the minimum while delivering evaporation efficiencies that exceed 90%. Depending on ambient temperature and air velocity, evaporative pre-cooling allows reducing the condenser entering air temperature for up to 10°C at the humidity of 50%. Equipping UltraCompact II chillers with evaporative pads results in significant electricity savings of up to 30% and even higher.
Evaporative cooling system can be equipped with pumping station which integrates circulator pump and water monitoring and treatment appliance for water reuse. The system constantly monitors water quality and tops up evaporative pre-cooling circuit only when it is necessary, thus allowing to save water. Evaporative system is designed to use unpurified water.
New chillers are designed for easy maintenance: all side panels are removable to access the components of refrigerant and water circuits; evaporative pads can also be detached for cleaning and accessing the condenser coils.
The UltraCompact II series chillers are also available with an integrated heat recovery, total or partial.
The next generation UltraCompact II chillers will be produced at the new Kaltra factory in Slovenia.
In 2018, Kaltra is planning to extend UltraCompact II range with free cooling models which, in synergy with evaporative pads option, offer great free cooling opportunities and excellent seasonal efficiency. Free cooling system will be based on microchannel heat exchangers with low airside pressure drop.
Kaltra is a provider of innovative cooling technologies and advanced cooling products for mission-critical applications, such as data centers, cleanrooms, contaminant-free areas, processing plants, and other facilities where the reliability and energy efficiency are key factors. Kaltra’s cooling equipment range includes precision cooling systems, air-cooled and water-cooled chillers, evaporative cooling solutions, dry coolers, and condensers.
