We are REKUPEX and we offer. The high efficiency recuperative exchangers. For your heat recovery ventilation systems and air recuperative project. We are happy to be official proud dealer of Czech producer RECUTECH. ABOUT Super efficient REK+ aluminium heat exchanger. REK+ counterflow plate heat exchanger is for transfer of heat between incoming and outgoing air in a ventilation system. The heat exchanger does not mix dirty and fresh air, or transfer humidity. It only transfers heat. Efficiency up to 96% guaranteed by patented technology. Optimized pressure loss computer simulations used. Double folding technology for all the range = the best tightness and durability on the market. Calculation software and DLL library. Possibility to have inbuilt bypass. Possibility of Combi Solution. Certifikation: Eurovent, ILH, TÜV, EAC, QMS, OHMS, EMS. Recutech – Production show. Video will open in a new window. Using the mobile app? Results of exchanger testing. Tested according to EN 308. The inward/outward air flow ratio is 1:1, the outward air temperature -5 °C, and relative humidity 25%. Internal air temperature 25 °C, relative humidity 80%. Air flow volume 150 m3/h – Efficiency 96,2% – Face air flow speed upon entering the recuperator 0,5 m/s – Pressure drop – supply – 22,1 Pa, exhaust – 32,2 Pa. Air flow volume 450 m3/h – Efficiency 95,5% – Face air flow speed upon entering the recuperator 1,5 m/s – Pressure drop – supply – 99,3 Pa, exhaust – 145,8 Pa. Air flow volume 750 m3/h – Efficiency 96,2% – Face air flow speed upon entering the recuperator 2,5 m/s – Pressure drop – supply – 211,3 Pa, exhaust – 313,7 Pa.

The inward/outward air flow ratio is 1:1, the outward air temperature 1 °C, and relative humidity 78%. Internal air temperature 25 °C, relative humidity 28%, calculated by EUROVENT certificated software. Diagram of Efficiency EFF [%] and Airflow volume AV [m3/h] – exchanger REK+31-400-22. DIMENSIONS OF REK+ EXCHANGERS. COMPUTER OPTIMIZED LAMELLA GEOMETRY. The efficiency of the heat exchanger is proportional to the outside temperature. The countercurrent air-to-air heat exchanger is made of durable materials. The casing is made of sheet aluminium and sealed with hot glue. The faces are glued using MS polymer. The heat exchangers do not contain silicone and they comply with the REACH 1907/2006 and RoHS 2011/65/EU Directives. It is composed of individual HIPS plastic plates, which are joined together by ultrasonic welding and are coated with sheet aluminium. The outgoing and incoming air flows between the plates and transfers energy to each other. The outgoing and incoming air does not mix in the heat exchanger. Only the heat is transferred. TECHNICAL DATA AND OPERATING CONDITIONS. Operating temperatures -40°C to +80°C. Relative humidity 0% to 100%. Maximum recommended flow through the faces is 3 m/s on the inlet. We recommend using a heat exchanger with a balanced ratio between the outlet and inlet, or with a maximum imbalance of +/- 50%. The maximum pressure difference between the inlet and the outlet is 800 Pa. The use of double-hem technology on all sizes ensures maximum tightness. The Eurovent certification guarantees up to 96% efficiency. This exchanger you can install instead of Recair, Heatex, Holmak, Klingenburg or Eri recovery corporation. Der Gegenstrom-Plattenwärmetauscher REK+ dient zur Übertragung von Wärme zwischen der Eingangsund Ausgangsluft im Ventilationssystem. Der Wärmetauscher mischt nicht verunreinigte und frische Luft, er überträgt auch keine Feuchtigkeit. Er überträgt nur Wärme. El intercambiador de calor por contracorriente con placas REK+ sirve para la transferencia de calor entre el aire de entrada y el de salida en un sistema de ventilación. El intercambiador de calor no mezcla el aire sucio y el aire fresco, ni transfiere hume.
