At the SPS IPC Drives in hall 5 at stand 170 and 270 the häwa GmbH presents cooling and ventilation solutions for cabinets. The exhibited cooling units KF1900 EX-P a cooling device with condenser with Microchannel Technology and KF 1000 RD, a filter fan with EC Technology constitute only a small extract from häwa’s vast portfolio of cooling solutions.
häwa’s new KF1900 EX-P cooling unit was designed for the application as attachment in the EX-P area and is deliverable with an enclosure from sheet steel or stainless steel. The EX-P cooling unit provides the degree of protection IP65 and the installed fans are approved for temperature class T4 (EX approvals external fans II 2G EEx d IIC T4). The display in front for the indication and adjustment of all parameters is placed behind a special protective cover. The KF1900 EX-P cooling unit is very easy to maintain, deliverable in versions of roof construction and of sidewall extension and is particularly well suited for the customer-specific application in the chemical sector, on offshore platforms or in refineries.
häwa’s cooling unit KF 1000 RD with sheet steel enclosure that is executed without filters and therefore, requiring little maintenance benefits from a slim design and minimal installation depth concerning partial installation. It offers a useful cooling output of 1000 Watt through its integrated condensate vaporization and was designed for an operating temperature range of +20°C to +50°C. A display in front provides the easy retrieval and setting of all functions and parameters. The KF 1000 RD cooling unit is perfectly suitable for the application in cabinets for industrial use.
häwa’s product portfolio includes a number of cooling units with condenser in Microchannel Technology and a useful cooling output from 500 up to 3000 Watt. Thanks to the Microchannel Technology the installation depth of the condenser is reduced by approximately 50 mm. Furthermore, the efficiency level of the devices increases since a part of the saved depth is used in order to achieve a more efficient flow of air around the condenser. Through the smaller size less refrigerants are needed (approximately 40% less than with conventional condenser tube-set), what significantly reduces the weight of the cooling units and contributes at the same time to environmental protection. Additionally, a enhanced thermal conductivity and higher corrosion protection can be achieved by the exclusive use of aluminum (whereas conventional condensers consist of copper and aluminum). From a useful cooling output of 1400 W, the devices offer an integrated condensate vaporization.
Filter fans with EC-Technology from häwa are executed very flat (only 6 mm looming) and offer an autonomous and infinitely variable rotational speed regulation. The EC-Technology involves that the fan runs with only a partial load and the rotational speed is adjusted by a module of the respective temperature inside the cabinet. Thus, power consumption and noise level decrease considerably, as the fan operates less often under full load and maximum rotational speed. Moreover, life expectancy of the device increases through less processes of switching on and off. The application of the filter fan with EC-Technology is particularly profitable where the power dissipation inside the enclosure fluctuates heavily or the up to now used filter fans have only short starting times/runtimes.
