Air cooled industrial liquid chiller, ErP2021, scroll compressors, R410A, 5-47,5 kW The new WRA ERP liquid chillers are the result of a design that has focused on reliability, energy efficiency, extended operating limits and extreme configurability. Thanks to dedicated technological solutions such as the oversized heat exchangers, the standard electronic expansion valve and the new high efficiency fans, each configuration of the WRA ERP chillers is characterized by high thermodynamic performances that exceed the most stringent minimum energy efficiency requirements imposed by the Ecodesign directive starting from 2021. Strengths Energy Efficiency: all WRA liquid chillers comply with the limits required by ErP2021 – SEPR HT (EU) 2016/2281 – SEPR MT (EU) 2015/1095. Extended operating limits: outdoor 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 for BRINE version. New SECBlue LIGHT programmable controller – SMP4600: equipped with advanced proprietary control logics, SMART LASER function and standard dynamic set point function. Installable outdoors: the electrical panel manufactured in compliance with EN 60204 and with IP54 protection degree allows the outdoor installation of all WRA units. Corrosion protection: the HDPE plastic tank, the no-ferrous hydraulic circuit (stainless steel/polymer) and the pump are corrosion-free and preserve the purity of the process fluid. New Version for Hydraulic Pressure Circuits New version with shell and tube evaporator integrated in the cylindrical tank (mod. 5A) LASERPACK ±0.5K and ±0.1K
