KOMFORT Ultra EC L2 300

Product catalog summary
Overview
The KOMFORT Ultra EC L2 300 is a compact heat recovery air handling unit designed for efficient supply and exhaust ventilation in residential and small commercial buildings. It utilizes heat recovery technology to minimize ventilation heat losses and maintain a comfortable indoor climate.

Design and Construction
The unit features a double-skinned metal casing with a 20 mm mineral wool layer for heat and sound insulation. It is compatible with 125 mm diameter air ducts and includes rubber-sealed spigots for airtight connections. The hinged panel allows easy access for maintenance.

Fans and Motors
Equipped with high-efficiency EC motors and centrifugal impellers, the unit offers excellent power consumption to airflow ratio, low noise levels, and a controllable speed range. The impellers are dynamically balanced for optimal performance.

Heat Recovery
The unit is available with two types of heat exchangers: a polystyrene plate cross-flow heat exchanger for heat recovery and an enthalpy plate cross-flow heat exchanger for energy recovery, which includes humidity recovery. The heat exchangers ensure complete separation of airflows to prevent odor and contaminant transfer.

Control and Automation
The S2 model includes a CDT E/0-10 speed controller, while the S14 model features an integrated control system with a wall-mounted panel offering functions such as speed selection, summer ventilation mode, and alarm indications. The S14 model also supports advanced settings via a USB connection to a PC.

Mounting Options
The unit can be wall-mounted, floor-mounted, or ceiling-mounted (for the E model). It allows for both left and right mounting configurations by swapping the service and back panels.

Technical Specifications
The unit operates on 230V power, with a maximum airflow of 300 m³/h and a sound pressure level of 33 dBA at 3 meters. It supports a temperature range of -25°C to +40°C and includes G4 and F8 filters for air filtration.

Accessories
Available accessories include panel filters, humidity and CO₂ sensors, silencers, air dampers, electric actuators, and a summer block for seasonal adjustments.
