Description

FEATURES

Efficient solution for supply and exhaust ventilation of enclosed spaces.
Available modifications with an electric preheater and/or reheater for cold climate conditions.
EC motors with low energy demand.
Supply air purification up to 99 % ensured by two integrated G4 and F7 filters. Additional air purification due to recirculation. An H13 filter is optionally available.

Upgradeable with an extract air duct to provide air extraction from the bathroom.
Easy installation.
Compact size.
Modern design.
Control via Android/IOS mobile application.

OPERATING PRINCIPLES

The supply and exhaust air dampers close when the air purification function is turned on.
The recirculation damper opens.

The room air circulates through the filters.
Then it is returned purified back to the room.

CONTROL

The units are equipped with a control panel.
A remote control is included in the delivery set.
WiFi connection available.
Control via a smartphone or a tablet based on Android or IOS.
Control via Android/IOS mobile application.

VENTS MICRA is available on the Google Play Store and the App Store

FANS

CASING

The units are equipped with efficient electronically commutated (ЕС) motors with an external rotor and impellers with forward curved blades.
These state-of-the-art motors are the most advanced solution 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 %.

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.

PREHEATER

SUPPLY AIR REHEATER

The MICRA 200 E ERV WiFi and MICRA 200 E2 ERV WiFi units are equipped with an electric preheater which protects the heat exchanger from freezing.

The MICRA 200 E1 ERV WiFi and MICRA 200 E2 ERV WiFi units are equipped with an electric reheater to raise the supply air temperature when necessary.

HEAT EXCHANGER

The MICRA 200 ERV WiFi unit is equipped with an enthalpy counter-flow 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.

Ventilation system arrangement

Each space requiring proper ventilation should be equipped with a single or several MICRA 200 ERV WiFi units.
A single unit is capable of ensuring efficient ventilation in spaces with floor area up to 100 m².

The MICRA 200 ERV WiFi 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).
