FEATURES
Air handling units for efficient supply and exhaust ventilation in flats, houses, cottages and other buildings. Heat recovery is provided by the rotary heat exchanger and minimizes ventilation heat losses. Controllable air exchange for creating the best suitable indoor microclimate. Compatible with round Ø 160 and 200 mm air ducts. Additional spigot for kitchen hood air duct connection. DESIGNThe fan casing is made of galvanized steel, internally filled with mineral wool layer for heat and sound insulation. The spigots are located at the sides of the unit and are rubber sealed for airtight connection to the air ducts. KOMFORT Roto EC D(2)E – model with electric heater. The insulation of KOMFORT Roto EC DE is 40 mm, for KOMFORT Roto EC D2E is 20 mm. Unit maintenance is performed from the bottom panel side. The distinctive feature of KOMFORT Roto EC D2E is a low casing profile. |
MOTORS
High-efficient external rotor EC motors and centrifugal impellers with forward curved blades are used for air supply and exhaust. EC motors have the best power consumption to air flow ratio and meet the latest demands concerning energy saving and high-efficient ventilation. EC motors are featured with high performance, low noise level and totally controllable speed range. Dynamically balanced impellers. AIR FILTRATIONTwo built-in filters with G4 and F7 filtration class provide efficient supply air filtration. Optionally, a H13 supply air filter may be used. The G4 filter is used for extract air filtration. MOUNTINGThe air handling unit is designed for suspension to a ceiling, wall mounting or mounting to a horizontal plane. |

KITCHEN HOOD
All the models are equipped with a fifth spigot for connection of the air duct from the kitchen hood. ROTARY HEAT EXCHANGERThe unit has a high-efficient rotary aluminium heat exchanger. The rotary heat exchanger is a short, rotating cylinder, filled with corrugated aluminium sheet layers. The air streams flow through them. The band layers of the heat exchanger first come in contact with the supply and then with extract air flows. Therefore the band is alternatively warmed up and cooled down and the extract air heat and humidity are transferred to the cold intake air. This way heat recovery reduces heat losses in the cold season and reduces operation load for air conditioner in the warm season. The advantages of the rotary heat exchanger as compared to the plate heat exchangers include no condensate generation, maintaining comfort air humidity and high freeze resistance. |
HEATER
The KOMFORT Roto EC D(2)E units are equipped with the electric heater. If the necessary temperature level of the supply air cannot be achieved through heat recovery, the heater turns on automatically and heats the air supplied to the premise. The heaters incorporate protective measures securing the safe unit operation. CONTROL AND AUTOMATIONKOMFORT EC D… S21 units are equipped with an integrated automation system. The remote control panel is not included in the delivery set (purchased separately). The S21 controller allows integrating the unit into the Smart Home system or BMS (Building Management System). The unit can be controlled via the Blauberg AHU mobile application via Wi-Fi.

Data provided for point 1 of the air flow diagram
Calculation of air temperature downstream of the heat exchanger:
t = toutd + khr × (textr - toutd) / 100,
where toutd – outdoor air temperature [°C] textr – extract air temperature [°C] khr – heat exchanger efficiency (according to the diagram) [%]
