Description

TwinFresh Expert RW-30-14 V.2 is a single-room energy-efficient supply and exhaust unit intended for decentralized ventilation of residential and commercial spaces as well as apartments and houses.

FEATURES

Efficient energy saving supply and exhaust ventilation in flats, houses, cottages, social and commercial spaces.
Reducing heat losses caused by ventilation due to heat recovery.
Humidity balance and regulated air exchange create individually controlled microclimate.

Controlled by Android or iOS smartphone or tablet.
Wi-Fi communication between several single-room ventilation units for coordinated operation.

DESIGN

TWINFRESH EXPERT RW-30-14 V.2 UNIT OPERATION LOGIC

The unit is designed both for reversible mode with energy regeneration and for supply or extract mode with no regeneration.

CYCLE I.

Warm stale air is extracted from the room, then it passes through the ceramic energy accumulator and while flowing through it, heats and moistens the ceramic accumulator by transferring thermal energy. After a while, as the ceramic heat exchanger gets heated, the ventilator switches to supply mode automatically.

CYCLE II.

Clean fresh air from outside passes through the ceramic energy accumulator, absorbs moisture and is heated up to the room temperature due to the accumulated heat. When the temperature of the accumulator drops down, the fan switches to extract mode and the cycle is renewed. The ventilator changes its operation mode between supply and extract ventilation every 70 seconds.

CONTROL

Connection of units to a single network via Wi-Fi for synchronous operation.
Connection of units to the Smart Home system.

Remote unit control from anywhere in the world.
The unit is controlled via control panel located on the casing of the ventilator or via a smartphone.

		VENTS TwinFresh V.2 is available on the Google Play Market and the App Store

MOUNTING

The unit is designed for through-the-wall mounting into a hole provided in the outer wall. The best ventilation solution is pairwise installation of reverse phase synchronized units. Some units ensure supply of fresh air to the room and the other units extract air from the premise. This way the most efficient balanced ventilation is arranged.
