RECOM 6 RT EC Rotary Heat Recovery Unit

Why choose RECOM 6 RT EC?

Feel the difference with RECOM 6 RT EC - an extremely powerful ceiling-mounted air handling unit designed for large spaces and maximum comfort. The white-painted casing with 40 mm mineral wool insulation ensures that despite the high 710 m³/h capacity, the unit operates quietly (from 24 dB(A)) and effectively retains heat. Mounted under the ceiling, it frees up floor space and remains invisible in your interior.

By using modern and efficient EC motors, your ventilation system will operate very economically, meeting the A energy class. The integrated Wi-Fi module provides the convenience of controlling air quality directly from your smartphone, no matter where you are.

Rotary technology - comfort without condensate

The heart of this unit is a high-efficiency rotary heat exchanger made of aluminum. It allows achieving up to 87% heat recovery efficiency, so in winter, the air supplied to the rooms is naturally warmed by the heat of the extracted air. The main advantage of rotary technology is that it maintains pleasant natural humidity in the home and prevents the air from drying out.

Furthermore, rotary heat exchangers require absolutely no condensate drainage system, which makes the installation of the air handling unit much easier, faster, and cheaper. It's the perfect choice for everyday home comfort without any extra worries.

Complete ventilation system with REC BalticVent

Even the most powerful air handling unit is just the foundation of a high-quality system. For the system to work quietly and in a balanced manner, it's necessary to select the right 200 mm diameter ducts, silencers, and diffusers. The ORO Haus team will help professionally configure and adapt the entire ventilation system for your home.

"RECOM 6 RT EC" features and capabilities

Advanced automation, smart control via Wi-Fi, and an efficient filtration system ensure that ventilation works flawlessly and requires minimal attention from you.

RECOM 6 RT EC is a very powerful ceiling-mounted ventilation unit, perfectly adapted for installation in spaces above suspended ceilings in larger homes or commercial premises. This guide will help you familiarize yourself with the main installation requirements. The full manufacturer's instructions can be found in the specifications tab.

What is in the box

The standard manufacturer package includes:

• Fully assembled air handling unit with 40 mm insulation, a 2.8 kW electric heater, and integrated automation with a Wi-Fi module.
• Filters: G4 class extract air and F7 class outdoor air filters.

What you will need additionally

For successful ventilation system installation, you will need to purchase additionally:

• Heavy-duty mounting hardware (threaded rods and nuts) [NOT IN PDF].
• Vibration isolation pads for noise transmission reduction [NOT IN PDF].
• Power cable and an appropriate circuit breaker (the unit draws up to 13.7 A).
• Ductwork system components, flexible connectors, and diffusers [NOT IN PDF].
• External sensors (e.g., CO₂ or humidity), if you plan to use them.

Dimensions and location selection

The external dimensions of the unit are 1445 mm in length, 932 mm in width, and 422 mm in height. Due to its 104 kg weight, a strong load-bearing structure must be prepared. When mounting above the ceiling, technical access from the bottom panel side must be left for free filter and component maintenance. This unit is adapted to handle air temperatures ranging from -25 to +40 °C.

Duct connection

Main round 200 mm diameter ducts (4 connections) and one 125 mm connection connect to this unit. To reduce vibration transmission to the duct system, flexible connectors are recommended [NOT IN PDF]. Ducts located in unheated spaces or supplying outdoor air must be properly insulated.

Condensate drainage

Unlike plate heat exchangers, this model uses a high-efficiency rotary heat exchanger, so a condensate drainage system is not required – moisture is effectively returned to the rooms and condensation does not form inside. This makes installation work significantly easier and cheaper.

Electrical connection

Electrical work must only be performed by a qualified electrician. The unit is designed for a single-phase network and powered by 220-240 V, 50 Hz. It is important to note that the maximum unit current with the powerful 2.8 kW integrated electric heater running reaches up to 13.7 A. Reliable grounding must be ensured and appropriately selected circuit breakers used.

Control systems

The air handling unit is very convenient to control via wireless Wi-Fi, using the manufacturer's "RECOM AHU" mobile app on a smartphone. It is also possible to additionally install a wired control panel (e.g., FPD screen) and integrate the unit into home BMS (Building Management Systems).

First start

Before leaving the system for continuous operation, carefully check:

• Whether the G4 and F7 class filters are correctly installed and clean.
• Whether all 200 mm duct connections are reliably sealed.
• Turn on the unit via the "RECOM AHU" mobile app and perform test system balancing, adjusting flows for large spaces.

Maintenance and filters

The guarantee of smooth ventilation is regular air handling unit filter replacement. The unit features G4 class extract air and F7 class outdoor air panel filters. Access to filters and internal components is done by opening the bottom maintenance panel part. The app itself will notify you when filters need updating based on engine hours.
