TwinFresh R-50, R-50-2  new series

Initial Costs Saving

• No need to pay for air ducts
• No need to pay for grilles
• No need to pay for installation of complicated ventilation duct system
• No need to pay for renovation after TwinFresh installation
• No need to pay for regular cleaning of the ducts from dust and other allergens

Energy Saving

• TwinFresh energy demand is as low as 3W. No need to push air through the ventilation duct system
• Extremely high ERV core efficiency up to 91%

Combination of the Initial Cost Saving & Energy Saving makes the TwinFresh application a perfect solution for those who require Easy and Efficient ventilation system for their homes

Features:

• Efficient supply and exhaust single room ventilation
• High-tech ceramic energy accumulator with regenerating efficiency up to 91%
• Reversible EC-motor with low energy demand up to 3 W and safe voltage 12 V
• Integrated automation with four operating patterns
• Silent operation (0.5 – 0.81 Sones)
• Easy installation due to a round telescopic duct adjustable from 913/16" - 181/2"
• Air purification with two built-in G3 filters
• Rated for continuous operation

Front grille (1)

• Modern design of the front grille makes it look great in any interior. The grille is fitted with a thermal actuator and automatic louvre shutters that are opened during operation of the ventilator and are closed during standby. The front grille is made of high quality snow-white ABS plastic.

Air filtration (2)

• Two G3 built-in filters provide fresh air free of dust, pollen, insects.

Motor (3)

• Reversible axial EC-motor driven fan is used for air supply and exhaust. The latest EC motor technology ensures low energy demand up to 3 W. The fan is powered by safe voltage 12 V. The motor has integrated overheating protection and ball bearings for longer service life.

Polymer ceramic energy accumulator (regenerator) (4)

• The ventilator includes a high-tech polymer ceramic energy accumulator with regenerating efficiency up to 91%.
• The unique regenerating accumulator is featured with a cellular structure and a large air contact area. It is made of polimer ceramics with high heat conducting and accumulating properties.
• No equally sized plate or tube recuperator is comparable with a polymer ceramic accumulator in terms of efficiency. As the air flow passes through the accumulator, either in extract or supply mode, it fills the entire cross section of the accumulator whereas only one half of the entire cross section is used in plate or tube heat recovery cores. Created in such a way low air resistance enables use of EC motors with extremely low energy demand.
  

  

Control and operating modes

• The automation system has four operating patterns:

1. Ventilation mode (extract or supply mode) at low speed with air capacity 14.7 CFM;
2. Ventilation mode (extract or supply mode) at high speed with air capacity 29.4 CFM;
3. Reverse mode (regeneration) at low speed with air capacity 14.7 CFM;
4. Reverse mode (regeneration) at high speed with air capacity 29.4 CFM

• The required operation mode is selected using the control panel supplied with the model TwinFresh RA. The control panel for the model TwinFresh R is available upon separate order.

Exterior Hood (5)

• The exterior is constructed of aluminum covered with a special polymer coating to ensure long-lasting protection from the elements. A hood protects water and foreign objects from entering the unit.

How the TwinFresh R Works

The ventilator is designed for two operation modes:
- Reversible mode with heat and moisture regeneration;
- Continuous Supply or Exhaust mode with no regeneration.

• CYCLE I. Warm stale air is extracted from the room passing through the ceramic accumulator, which captures up to 91% of the thermal energy of the air being extracted. As the accumulator gets heated, the ventilator switches to air supply mode.
• CYCLE II. As the fresh outside air passes the opposite way through the accumulator, it absorbs the heat and moisture which was extracted from the room air that was exhausted. As the temperature of the accumulator decreases, the fan switches back to extraction mode and the cycle starts all over again. The ventilator changes its operation mode for supply or extract ventilation every 70 seconds. This time interval can be adjusted during installation from 30 to 120 seconds.
