ABOUT
Super efficient – REK+ aluminium air to air 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
100% tightness testing
Easy handling – using handling strips
Calculation software and DLL library
PassiveHouse ready
Possibility to have inbuilt bypass
Possibility of Combi Solution
Certifikation: Eurovent, ILH, TÜV, EAC, QMS, OHMS, EMS

USE
The heat exchanger is used in heat recovery units, where it returns the exiting heat. The accumulated heat returns and thus significantly affects energy consumption. The efficiency of the heat exchanger is proportional to the outside temperature.
DESCRIPTION
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
GERMAN DESCRIPTION
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.
RUSSIAN DESCRIPTION
Противоточный пластинчатый теплообменник REK+ предназначен для переноса тепла между входным и выходным воздухом в системе вентиляции. Теплообменник не смешивает загрязненный и свежий воздух, а также не переносит влагу. Переносит исключительно тепло.
SPANISH DESCRIPTION
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
