HRUWALLRC is a bidirectional ventilation unit, often described as decentralized or pushpull, with regenerative ceramic heat exchanger. It is intended for single room installation, usually installed in synchronised pairs. The heat exchanger material together with its unique honeycomb structure gives a maximal 82% thermal efficiency ratio (74% acc. to 1254/2014 EU Directive reference measuring point). The operating principle is analogous to HRUWALL unit is working in alternating flow mode, switches the air flow directions every 40120 seconds (pushpull) and it’s equipped with energy efficient EC fan (maximum power consumption is only 6 W for HRUWALLRC15060). The unit casing is made of ABS plastic. A remote controller with LCD display is included in the set. We recommend installing the devices in pairs

The HRUSlimAIR heat recovery unit is designed for residential buildings. The HRU has a capacity of 250 m3/h @ 100 Pa, generated by energyefficient EC fans. Thanks to a counterflow heat exchanger made of a plastic (PET), it achieves up to 90% heat recovery An ERV version with an enthalpy exchanger that recovers moisture is also available. Builtin electric preheater protects heat exchanger against freezing, wireless radio communication connects controllers and sensors, and all of it is enclosed inside a selfsupporting, insulating EPP casing. HRUSlimAIR can be installed in up to 3 positions, thanks to a special condensate drain system.

The heat recovery ventilation unit HRU-PremAIR has an air flow capacity of 350 m3/h at 100 PA. Designed to use aluminum heat exchangers and EPP self-supporting casing. Heat exchangers that are used depend on the model, such as counterflow aluminium heat exchanger (HRV) or counterflow enthalpy exchanger (ERV).

Heat recovery ventilation unit HRUPremAIR is a modern device with 350 / 450 or 500 m3/h air flow @ 100 Pa. Unit is made from cutting edge materials aluminim heat exchanger and EPP selfsupporting casing. Depending on the model, following heat exchangers are used counterflow aluminium heat exchanger (HRV) or counterflow enthalpy exchanger (ERV). Enthalpy exchangers in HRUPremAIRE series have a polymer membrane that effectively recovers heat and moisture from the extract air. Such membrane works like a membrane in waterproof trekking clothing i.e. it allows water vapour to pass through, but not liquid water and air. The enthalpy exchanger also blocks the transfer of odours, bacteria and spores. The exchanger material, is needless to say, primarily optimized for maximum heat recovery efficiency. PremAIR air handling units optionally can be equipped with the Constant Flow system, whose task is to maintain a constant air flow in the installation.

The FLX-PLO-EPP-F plenum boxes are part of the FLX-REKU air distribution system designed for domestic mechanical ventilation systems, so-called the MVHR system, to which an air valve and FLX-HDPE / FLX-HDPE-A ducts with a diameter of Ø75 are mounted.

HRUWALL is a singleroom decentralized heat recovery unit for concealed installation. The unit comes with a ceramic heat exchanger which boasts a maximum heat recovery ratio of 90% (the nominal heat recovery ratio is η=74.3% as per EN 1314182011). The energyefficient EC fan changes the running direction every 70 seconds to alternate between air supply and air exhaust. Low energy consumption and extremely low operating noise make this heat recovery unit a recommended solution for nonstop operation. The heat recovery unit has three speed levels to choose from, depending on the size of the area and indoor demands. HRUWALL10025 provides a sufficient air change level in areas up to 19m2. HRUWALL15060 provides a sufficient air change level in areas up to 45m2. We recommend installing the devices in pairs.

EPP manifold boxes are used for heat recovery ventilation (MVHR). Due to EPP's insulating properties, MVHR manifolds do not need to be insulated. Manifold boxes are intended to distribute 75mm ducting around the house. The number of connectors varies based on the specifications of the user: 4-18 spigots.

The insulated manifold box is used for mechanical ventilation systems with heat recovery (MVHR). MVHR manifolds do not need to be insulated onsite thanks to the insulating properties of EPP. Manifold boxes are designed for distribution of 75mm semi-rigid ducting around. The number of connectors varies depending on the user's specifications: 6-13 connection spigots.

Round ventilation duct made of expanded polypropylene (EPP). The most important features of the product are rigid construction, low weight, easy assembly (integrated malefemale coupling) and good thermal insulation. EPP ducts, used, for example, as sections of the supply and exhaust ventilation systems with heat recovery, do not require additional insulation. The system eliminates the formation of thermal bridges. Lenght EPP ducts 1 m sections Diameters 125, 160 and 200 mm. Wall thickness 15 mm Thermal conductivity 0.039 W / m*K Airtightness class ATC2 (old D) @ 90Pa acc. to PNEN 17192201901

FLXPLO / FLXPRO plenum boxes are components of the FLXREKU system intended for domestic mechanical ventilation systems, also known as mechanical ventilation heat recovery (MVHR) or heat recovery ventilation. The low profile plenum boxes require less installation space than standard solutions, which is very convenient when they should not be prominent once concealed. This advantage helps free up usable indoor area. FLXPLO plenum boxes are made of galvanized steel sheet. Plenum boxes made from stainless steel are available on request. Available also insulated plenum box version FLXPLI and FLXPRI. These plenum boxes have inside a insulation lining made from 9 mm thick rubber foam. FLXPLO plenum boxes are equipped with duct connection spigot Ød2 with a EPDM seal – this type of connection with FLXHDPE ducting is airtight and easy to install.

The smog filter is designed for effective filtration of the socalled particulate matter. The PM2.5 and PM10 particles are the main component of smog, which have an optical diameter of 2.5 and 10 μm (micrometers). The filtration efficiency (removal) of PM2.5 particles reaches up to 73%, and PM10 particles up to 81% (according to tests carried out with a dust particle measuring device). The smog duct filter consists of a sealed filter box and two filters prefilter and smog filter. It is recommended to install a smog filter on the supply ducts in domestic ventilation and heat recovery systems. In the MOCarzCA version prefilter I3 was replaced by an activated carbon prefilter (or activated charcoal). The main purpose of using such a material is deodorization of air and preliminary cleaning of dust and gaseous pollutants. Activated carbon has a huge adsorption surface, which effectively "binds" on its surface particles of pollutants, bacteria, hydrocarbons.

Electrostatic precipitator eMOCarz was design for residential buildings. Compact size and exceptionally low pressure drop makes it suitable for residential heat recovery systems, with little impact on system performance. The filtration efficiency of ePM1 and ePM2.5 particles, the main component of smog, is as high as 95%. Polluted air initially passes through a steel mesh prefilter (which retains larger fractions), then is positively ionized in an electric field due to the “crown discharge” effect. In the last stage, the previously charged particles, are pulled by electrostatic force toward horizontally mounted aluminium plates (electrodes) and build up on their surface. Electrostatic filters (precipitators) have low power consumption (only few Watts), long service life and most of all there’s no need to exchanged dirty (clogged) filters. It is enough to clean in with water and detergent once or twice a year. There is a led status indicator on the casing.
