Heat Recovery Unit

HEAT RECOVERY DEVICE Heat recovery units are produced in order to save energy in the neighborhoods where fresh air is needed. It is produced in the air flow range of 500 m3 / h to 5000 m3 / h. It is designed in such a way that it can be easily installed and maintained at a height that can be placed in the suspended ceiling. High efficiency recuperator with centrifugal fans, silent direct coupled motor,is a compact device with maximum sound insulation and full sealing cell with heat isolation. In today’s conditions, buildings are constructed as highly insulated in order to prevent energy loss. The construction techniques developed in recent years have led to the construction of buildings in a more rigid and sealed structure.

TECHNICAL SPECIFICATIONS •

It meets the fresh air requirement of the environment in the areas it is used and prevents condensation in winter. • Heat recovery ventilation system helps in the treatment of asthma and allergy by removing dust and microscopic dust insects from the environment. • It provides the fresh air requirement of crowded environments such as classrooms and dormitories with energy saving up to 72%.

BODY STRUCTURE

The whole body is made of 1 millimeter galvanized sheet painted with electrostatic RAL 7035 color code. 25 mm thick glass wool insulation material is used for sound and heat insulation.

FANS

Directly driven forward-missing bladed radial fans with dynamic and static balances are used. Radial fans are designed to be eaten 200 Pa outside pressure according to the project conditions. The fans are manufactured as single speed 2 speed or 3 speed according to order conditions. The speed control is suitable motor and has low noise level. The sound levels of the fans were chosen considering the flexible channel. Carriage heat exchanger In the fresh air device with carriage heat recovery heat exchangers with high and low pressure losses are used.

FILTER G4 class synthetic fiber based filters are used which are easily accessible and cleanable. Both fresh air and exhaust effort inlets are equipped with filters. In this way, both the particles in the air are retained and the plate heat exchanger is protected.

ELECTRICAL HEATERS AND HEAT CONTROL

Different sizes and capacities of electric heaters are produced for each model in order 

to connect to the fresh air flows of heat recovery devices depending on the place of use 

and need. The outer body of the resistors is made of stainless steel pipe. Thus, corrosion 

resistance is high

Electric heaters are manufactured with rectangular cross section in accordance with fresh air outlets from heat recovery units and suitable for flanged connection.

SPEED CONTROL In accordance with the changing needs, the fan speed can be adjusted with speed control to save energy
