ABOUT RSF+ plastic air to air exchangers
The RSF+16 plastic heat exchanger
offers the highest effi ciency and optimum
pressure drop thanks to the unique plate
shape and 3,2 mm plate distance. The product
is available in lengths from 100 mm to 600 mm.
The Net Energy Performance is the
difference between the energy recovered
by the heat exchanger and energy
necessary to overcome its pressure drop by
the fans. The RSF+16 and generally
RECUTECH heat exchangers achieve top
values of this important parameter.
Every single product manufactured in
RECUTECH including the RSF+16
goes through strict tightness control.
We guarantee that the leakage of our
heat exchangers is always below 0,5 % of the
nominal air fl ow.
RECUTECH are committed to making the best
efforts to protect the environment. All our products are strictly silicone free.
The RSF+16 is ideal solution for compact
residential heat recovery units. The ratio of
effi ciency and pressure drop provides you with
the best Net Energy Performance. The
dimensions are compatible with the most
common solution on the market (366x366).

DIMENSIONS OF RSF+ EXCHANGERS
KEY TO CODING OF RSF+ EXCHANGERS
COMPUTER OPTIMIZED LAMELLA GEOMETRY AND EFFICIENCY
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 -20°C to +60°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 pressuredifference between the inlet and the outlet is 800 Pa.
The use of ultrasonic welding technology on all sizes ensures maximum tightness.
The Eurovent certification guarantees up to 95% efficiency.
