MICRA 100 single room air handing unit with heat recovery

• Efficient solution for supply and exhaust ventilation of enclosed spaces.
• Electric pre-heater or post-heater variant available for cold climate conditions.
• Heat exchanger with an enthalpy membrane variant available for humid and hot climate conditions.
• Low-energy ЕС fans.
• Excellent noise control (25-38 dBA).

• Supply air purification ensured by two built-in G4 and F8 filters (optional H13).
• Upgradeable with an exhaust duct to provide air extraction from the bathroom.
• Easy installation.
• Compact size.
• Modern design.

• Polymer coated metal casing decorated with an acrylic front panel.
• Thanks to the modern design the unit can seamlessly blend with most any interior design.
• Heat and sound insulation is ensured by a layer of 10 mm cellular synthetic rubber.
• The front panel provides convenient access for filter maintenance and has a lock for extra security.

• The unit has two ø 100 mm inlet and outlet pipes for fresh air intake and stale air extraction outside.
• The third ø 100 mm pipe (included) can be additionally fitted to the unit to connect the exhaust air duct from the bathroom.

• Supply air cleaning is provided by G4 and F8 panel filters (PM2.5 > 75 %).
• To meet more stringent air purity requirements an F8 filter can be replaced with an H13 (PM2.5 > 95 %) (purchased separately).
• Extract air is cleaned by a panel-type G4 filter.

• The unit is equipped with supply and exhaust air dampers which activate automatically to prevent drafts while the unit is off.

• The units feature efficient electronically commutated (ЕС) motors with external rotor and impellers with forward curved blades.
• These state-of-the-art motors offer the very best in energy efficiency today.

• EC motors are characterised with high performance and optimum control across the entire speed range.
• In addition to that the efficiency of electronically commutated motors reaches very impressive levels of up to 90 %.

• Operation in a cold climate may result in condensate freezing in the exhaust air duct and the external hood.

• Therefore, it is recommended to install the NE Micra 100 heater (purchased separately) to prevent icing.

• Micra 100 units are equipped with an electric pre-heater which protects the heat exchanger from freezing.

• Micra 100 E1 units feature an electric post-heater to raise the supply air temperature as necessary.

• Micra 100 units are equipped with a counter-flow heat exchanger with a polystyrene core.
• In the cold season the extract air heat is captured and transferred to the supply air stream which reduces the ventilation-generated heat losses.
• However, this process may be associated with condensation which is collected in a special drain pan and evacuated outside via the exhaust air duct.
• In the warm season the ambient air heat is transferred to the exhaust air stream.
• This allows for a considerable reduction of the supply air temperature which, in turn, reduces the air conditioning load.

• Micra 100 ERV units are equipped with a counter-flow heat exchanger with an enthalpy membrane.
• In the cold season the extract air heat and moisture are transferred to the supply air stream through the enthalpy membrane reducing the heat losses from ventilation.
• Consequently, it is the ambient air heat and moisture transferred to the exhaust air stream through the enthalpy membrane in the warm season.
• This allows for a considerable reduction of the supply air temperature and humidity which, in turn, reduces the air conditioning load.

• Freeze protection
• There are two types of freeze protection available to protect the heat exchangers in the cold season.
• Micra 100 features an exhaust air temperature sensor downstream of the heat exchanger which disables the supply fan to let the warm exhaust air raise the heat exchanger temperature.
• Once the heat exchanger temperature has returned to normal, the supply fan is re-enabled and the unit reverts to normal operation.
• Micra 100 E units are equipped with an electric pre-heater which warms up the supply air upstream of the heat exchanger to prevent its freezing.
• These features ensure a continuous balanced air exchange regardless of ambient air temperature variations.
• Control
• The units are equipped with a control panel.
• Remote control panels are supplied as standard.

• Following functions are available:

• Each space requiring proper ventilation is equipped with a single or several Micra 100 units.
• A single unit is capable of ensuring efficient ventilation in spaces with floor area up to 100 m².

• Micra 100 units can be upgraded with a bathroom exhaust air duct. 
• To enable such a configuration the units can be additionally equipped with the optional ø 100 mm fitting pipe (supplied as standard).
