As part of the investment for the RWS Retail Park in Kętrzyn, Ratherm provided a complete ventilation and air conditioning solution. The installation included 2 XD air handling units with built-in condensing units and a heat pump function, allowing for independent operation in both cooling and heating modes. The system is complemented by 6 XK air handling and conditioning units, equipped with either rotary or plate heat exchangers, tailored to the specific requirements of the facility's different zones.
