CASING

Polymer coated metal casing decorated with an acrylic front panel. Due to modern design, the unit matches well with any interior. 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 spigots for fresh air intake and stale air extraction outside. The third ø 100 mm spigot (included in the delivery set) can be additionally fitted to the unit to connect the extract air duct from the bathroom.

FILTERS

Intake air cleaning is provided by G4 and F8 panel filters. To meet more stringent air purity requirements, an F8 filter can be replaced with an H13 filter (purchased separately). Extract air is cleaned by a panel G4 filter.

HEAT EXCHANGER

The MICRA 100 units are equipped with a counter-flow heat exchanger with a polystyrene core. In the cold season the extract air heat is transferred to the intake air stream which reduces heat losses through ventilation. However, this can lead to formation of condensate that is collected in a special drain pan and is drained off outside through the exhaust air duct. In the warm season the ambient air heat is transferred to the extract air. This allows for a considerable reduction of the supply air temperature which, in turn, reduces the air conditioning load.

The MICRA 100 ERV unit is equipped with a counter-flow enthalpy heat exchanger. In the cold season the extract air heat and moisture are transferred to the supply air stream through the enthalpy heat exchanger reducing the heat losses through ventilation. The ambient air heat and moisture are transferred to the extract air through the enthalpy heat exchanger 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.

SUPPLY AND EXHAUST AIR DAMPERS

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

FREEZE PROTECTION

The MICRA 100 unit features an exhaust air temperature sensor downstream of the heat exchanger which disables the supply fan to let the warm extract air raise the heat exchanger temperature. Then the supply fan is turned on and the unit reverts to normal operation. Freeze protection for MICRA 100 E1 units is implemented with a preheater.

The units feature efficient electronically commutated (ЕС) motors with an external rotor and impellers with forward curved blades. In addition to that, the efficiency of electronically commutated motors reaches very impressive levels of up to 90 %.

NE MICRA 100 HEATER FOR CONDENSATE FREEZE PROTECTION (OPTIONAL)

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.

VENTILATION SYSTEM ARRANGEMENT

MICRA 100 application in an office space Each space requiring proper ventilation should be 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 extract air duct. For this, the units can be additionally equipped with an optional ø 100 mm spigot (included in the delivery set).
