WRA ErP - Chiller
3Pages

WRA ErP The new WRA ERP liquid chillers are the result of a design that has focused on reliability, , and . Thanks to dedicated technological solutions such as imposed by the Ecodesign directive starting from 2021. Process chillers work with high heat loads continuously throughout the year. It is therefore very important that the chiller guarantees the highest performance under all operating conditions. All WRA chillers comply with the limits process applications Thanks to the dedicated versions and accessories, operation at full load is guaranteed up to +45 °C outside air temperature during the summer season and -20 °C during the winter season in the LT version. Standard WRA ErP units produce chilled water with a maximum evaporator outlet temperature of up to +30 °C; minimum standard temperature +5 °C and -10 °C in the BRINE version. The new LT versions for low ambient temperature -20°C, the Brine version for low water outlet temperature Tw-10°C, and the new version for pressurised hydraulic circuits expand the technical equipment of the WRA ErP range, which is therefore able to meet the most varied application requirements, guaranteeing maximum safety of the production process in which the chiller is integrated. General Features External Air Temperature max +45 °C min -20 °C for LT version. Maximum evaporator outlet temperature up to +30 °C; minimum standard temperature +5 °C and -10 °C in BRINE ver
