Description
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 125, 160 and 200 mm air ducts. Additional spigot for kitchen hood air duct connection.

DESIGN

The fan casing is made of galvanized steel, internally filled with mineral wool layer for heat and sound insulation. The spigots are located at the top of the unit and are rubber sealed for airtight connection to the air ducts. The insulation of KOMFORT Roto EC SE 280, 400 and 600 is 40 mm. KOMFORT Roto EC S(2)E: model with electric heater.

KITCHEN HOOD

All units are equipped with a 5th spigot for connection to the kitchen hood air duct.

 

FANS

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 FILTRATION

Two built-in G4 and F7 filters provide efficient supply air filtration. The unit KOMFORT ROTO EC S2E 280 features F7 filter.The G4 filter is used for extract air filtration.

HEAT RECOVERY

The unit has a high-efficient rotary heat exchanger.The rotary regenerator is a short, rotating cylinder, filled with corrugated aluminium sheet layers. The air streams flow through them.The band layers of the heat regenerator 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 regenerator as compared to the plate heat exchangers include no condensate generation, maintaining comfort air humidity and high freeze resistance.

  HEATER

The KOMFORT Roto EC SE 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.

MOUNTING

The units can be fixed to the wall or mounted on the floor.During mounting stage the front and the back panels can be reversed providing either left-handed or right-handed unit mounting.

CONTROL AND AUTOMATION

KOMFORT Roto EC S... 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.

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) [%]
