K°OOLING KNOW-HOW FOR TODAY AND TOMORROW
14. September 2018 Visitors to the CHILLVENTA trade fair, from October 16-18 in Nuremberg will be invited to take a view beyond the horizon to see how Kelvion Heat Exchangers help reduce energy consumption and offer increased pressure rating CO2 products to benefit applications in the retail sector and much more … Today and tomorrow specifiers, contractors, wholesalers or investors have to take sustainable decisions on optimal, high quality K°ooling – including design parameters, energy savings, superior defrosting, material selection, maximum chilled goods protection, narrow thermal profiles and efficiency. Therefore it is good to know that there are innovation experts to help meeting K°ooling demands now and in the future.
Kelvion’s heat exchanger coils for data center cooling, process heating, cooling, air handling units, heat pumps and chilled beams, to name but a few applications, work across a broad range of liquids, temperatures and pressures. We will be displaying coils from 5mm through to 22mm in a variety of pitches and profiles to meet the many diverse requirements in applications.
Kelvion’s HVAC OEM ranges on display, with tube diameters of 8, 10, and 12 mm, offer lighter, more compact and more cost effective units. The new 8mm coils provide a reduced air side pressure drop and boast a 40% reduced refrigerant charge, compared to 12mm coils.
The second product at this year’s CHILLVENTA will be the new gasketed plate heat exchanger NP150X for district cooling stations, midsize data center cooling, and for high rise building cold supply. The adoption of a plate with shallower plate gap (1.8mm) and a smaller pitch ensures the highest heat transfer performance. The New NP-Series withstands an extremely high test pressure of up to 42bar (g) and is fully interchangeable with other gasketed plate heat exchangers.
Underlining our forward-looking credentials are the GBH-HP, GKS and GVH brazed plate heat exchangers. GBH-HP, for transcritical and subcritical CO2 systems up to 140bar, features safety pressure factors for supermarket refrigeration. The GKS series is used in heat pumps where its newly-shaped flow cells, ensure a higher turbulence and improved heat transfer. The GVH series, for laser cooling and ammonia use, unifies the brazed plate heat exchanger’s compact design and economy, with the benefit of a shell-and-tube heat exchanger.
Another future-oriented and effective new product on show will be the Kelvion CMX blast freezer, available from 13-116kW. An increase of 65% in performance compared to its predecessor.
The electrical power consumption has been reduced considerably, and the air flowrate for blast freezing has been increased by 31% to a maximum of 86.490m³/h. The saved electrical energy contributes to increasing the actually delivered cooling capacity. Precisely matched and even more flow optimized fans and heat exchangers result in an improved distribution of air in the cooler.
The evaporator’s surface can now be specified up to 685m².
In addition, Kelvion is introducing a new version of the KDC unit cooler for 90bar (g) – specifically developed for highly reliable and safe transcritical CO2 refrigeration systems. The air cooler is intended for uses in commercial HVACR, cold rooms, and freezer rooms. Its dual air discharge enables uniform distribution of temperature, and two fan speeds allow either high air capacity, or quiet operation. The new 90bar version provides maximum cooling duty of 1.7 to 23 kW.
New V-Bank condensers with multiple tube and fin patterns enable a flexible mix and match from a modular range. With today’s increasing demands for refrigeration, air conditioning and data center cooling, coupled with the rising global trend of urbanization, Kelvion customers demand for more cooling capacity per square meter has never been higher. The new range is available with a full portfolio of accessories including fan speed control, smart control and adiabatic cooling.
Additional products and services on display during the show are: new condensers, cooling towers, and Kelvion’s updated online product selection tool with new products and more user languages to choose from. Rigorous cooling capacity testing can be experienced at Kelvion’s R&D cold room test chamber that will be conducted and presented during the fair.
