REC Temovex RT-250S-EC-RS

Product Description

The REC Temovex 250S-EC-RS is an air handling unit (AHU) designed for highly efficient ventilation and heat recovery. It is designed as a part of the white goods range and is ready to be installed on the floor in a bathroom, laundry, or similar. The RT250S-EC-RS consists of fans, filters, an after-heater (electric or water), automatic by-pass, an integrated control panel, and a counter-flow heat exchanger. The casing is made of double hot-galvanised sheet metal with 30 mm insulation between the sheets. The front and side panels are white (RAL 9016, powder painted), and the front door has a magnetic strip to keep it closed. Our counter-flow heat exchanger makes it possible to utilize the thermal energy in the used indoor air and use it to heat the fresh incoming air, also ensuring no leakage between used and fresh air. This results in good operating economy and a sound and comfortable indoor climate.

Key Features:

• ECO2 Control System: An advanced system for low-energy and passive houses, comprising: air flow boost for warm and cold air, modes for cooker hood and stove/fireplace compensation, a mode for energy saving, room or exhaust air control, and advanced night cooling.
• The Most Quiet in its Class*: Recognized as one of the quietest units in its category (Acc. to The Swedish Energy Agency's test in February 2010).
• Lowest Power Consumption (SFP)*: Features the lowest specific fan power in its class (Acc. to The Swedish Energy Agency's test in February 2010).
• High-Efficiency Counter-Flow Heat Exchanger: Ensures effective heat recovery and a comfortable indoor climate.
• EC Fans with Constant Flow Control: Electronically commutated fans with external rotor motor. Each fan is individually set, continuous from 0-100% (dimension to approx. 70-80% of maximum flow), ensuring the air flow is kept at the set level. Fan motors have integrated overheating protection, and impellers have forward-bent blades. Fans have electric plugs for easy service/exchange.
• Integrated Control Panel: A user-friendly control panel is integrated in the front (behind the door). Option to purchase separate remote panels (three different versions).
• Automatic Stepless By-pass: For summer operation, ensuring cool indoor air is recovered on warm days.
• Filters: A filter alarm is integrated, indicating once a year when it's time to check/exchange filters.
