Heat recovery ventilation - Import export

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.

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

HRUWALLWI model ductless heat recovery unit comes equipped with a WiFi module. Its basic parameters, including max. heat recovery 82%, airflow rate 60 m3/h, and low sound power level 38 dB (A), are identical to those of the HRUWALL units. Methods for pairing devices and controlling them are different. With the addition of a WiFi module, the device can be connected to a local wireless network and controlled via a mobile app. Moreover, the app allows the pairing of devices by assigning two or more heat recovery units to a group. It is possible to have many groups so that 1 application can serve all HRV units in a building. A temperature sensor and relative humidity sensor are built into the HRUWALLWI, and the app displays their values.

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 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).

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.

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 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.
