DRX OPTI H

Recuperator connections: located in a horizontal position
Efficiency: DRX 300 H OPTI - do 350 m³/h DRX 400 H OPTI - do 450 m³/h DRX 500 H OPTI - do 550 m³/h
Energy efficiency class: A
Controller: Defro Air
Efficiency: to 95%
Standard equipment: The air handling unit is equipped with a unit operation controller with a 4.3" color display, a set of wall brackets.
Optional equipment - for an additional fee: ST-505 internet communication module (LAN) or WiFi RS internet communication module. Additionally, it can be equipped with a CO₂ sensor and an HR humidity sensor. Possibility of using elements for ceiling mounting: mounting console suspended from the heat recovery unit or on a base for the heat recovery unit.

Modulating pre-heater

Pre-heater for even greater control of the exchanger against freezing. AFC system – ANTI FREEZE CONTROL – working with a modulated heater.

100% Bypass

Only 100% bypass guarantees fresh and cool air in the summer.

Quiet operation

Our recuperators are among the quietest ventilation units available on the market. This is due, among other things, to the use of special EC radial fans dedicated to heat recovery.

Thermal and acoustic insulation

Thanks to the use of a thick layer of insulation, the air handling unit is protected against condensation of water vapor in the recuperator, and heat losses are virtually eliminated.

Opening from two sides

Our ventilation units have inspection flaps on both sides of the recuperator. This gives us easier access to inspection activities. Possibility of rotating the control unit and universal installation.

Wall mounting console

Set includes - 2 pcs.
