Heat Recovery Units
The ISIS heat recovery unit is designed for residential use, available in two sizes with airflows of 300 and 500 m3/h. It features high heat transfer efficiency up to 90%, integrated electric heating for low temperatures, and a bypass for summer cooling. The unit is easy to install, suitable for dry interiors with temperatures from 0°C to +40°C and relative humidity up to 80%. The housing is made of insulated sandwich panels, painted white (RAL 9010).
Specifications for different models include output power characteristics, noise data across frequency bands, and efficiency graphs. The HR-A-03 and HR-A-05 models are highlighted with specific sound power levels and sound pressure values.
The unit must be installed vertically and securely, with sufficient access for maintenance and free from flammable materials within specified distances. Air ducts connect via a rubber-sealed circular neck, and a siphon is necessary for condensate exhaust.
The ISIS units come with a remote controller and a 5-meter communication cable. Key features include fan speed control, electric heater output control, frost protection, and filter soiling indication. Accessories such as siphons and communication cables are available with specific ordering details.
Wiring diagrams are indicative, and installation should follow the product's nameplate ratings and instructions. A differential pressure switch indicates air filter pollution.
The coding system explains heat efficiency, presence of a bypass, electric heater, filter type, installation orientation, and nominal airflow.
The VENUS series offers nominal airflows of 150, 300, 500, and 700 m3/h with heat recovery efficiency up to 93%. It features AC or EC fans, low noise levels, and a compact design suitable for under-ceiling installations. The VENUS Comfort model includes advanced regulation systems and can be equipped with internal electric preheating.

Required accessories include siphons and temperature sensors for room and duct measurements. Optional accessories include manual control shut flaps, with recommended combinations provided for different unit types.
The document outlines various models of heat recovery units, including HRB and ALFA series, with specifications for horizontal and vertical installations. The units are designed for both indoor and outdoor use, with efficiency up to 93%. They feature EC motors for low energy consumption, double skin insulation, and integrated heating options.
Installation guidelines emphasize following the rated values and instructions provided directly on the device. Wiring diagrams are for informational purposes only, and the recommended minimum rating for electrical input power cables is specified in the manual.
Recommended combinations of unit types with accessories such as heaters, silencers, and sensors are provided. The document also includes noise specifications and performance characteristics for different models.
Necessary and optional accessories are listed, including servodrives, electric heaters, CO2 sensors, and filtration inserts. Each accessory is described with its function and compatibility with specific unit types.
The ALFA 95 series is highlighted for its smart regulation with touchscreen control, suitable for commercial applications. It operates efficiently in ambient temperatures from -20°C to +60°C, ensuring air free from pollutants.
Detailed technical parameters for each model are provided, including voltage, frequency, rated input, and total current. Characteristics of electric batteries and motors are also detailed, along with airflow and temperature specifications.
Operational diagrams and performance graphs illustrate the efficiency and noise levels of the units under various conditions. The heat recovery efficiency is shown to vary slightly between humid and dry environments.
