ALNOR VENTILATION SYSTEMS LTD - Ventilation Systems Manufacturer

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).

Round spiral ducts are available in diameters from 80 mm to 1600 mm. The ducts are available as made of 0.4 mm to 1.8 mm thick metal sheet; the ducts in diameters of DN 160 mm or greater are also available with corrugation for improved stiffness and vacuum strength. The corrugations are available as a standard feature for diameters of DN 250 mm to DN 1600 mm. All spiral ducts made from galvanized steel sheet, stainless steel sheet or aluminium sheet meet requirements of air tightness class D according to EN 12237.

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.

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.

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 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.

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.

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
