DESIGN

FANS

Polymer coated metal casing decorated with an acrylic front panel. Heat and noise 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 pipes for fresh air intake and stale air extraction outside. The third Ø 100 mm pipe (included in the scope of delivery) can be additionally fitted to the unit to connect the exhaust air duct from the bathroom.

The units feature efficient electronically commutated (EC) 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 %.

AIR DAMPERS

HEAT AND ENERGY RECOVERY

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

AIR FILTRATION

Supply air cleaning is provided by the G4 and F8 filters. To meet more stringent air purity requirements the F8 filter can be replaced with an H13 Filter (purchased separately). Exhaust air is cleaned by the panel filter G4.

OPERATING PRINCIPLE

The cold outdoor air passes through the filters and the heat exchanger and then is delivered to the serviced space by the supply centrifugal fan.
Warm stale air from indoors passes through the filter and the heat exchanger and is discharged outdoors by the centrifugal fan.
The supply and exhaust air flows are fully separated which helps eliminate the possibility of odour or microbial transfer between the streams.

The Freshbox 100 WiFi units are equipped with a counter-flow heat recovery core with a polystyrene core.

In the cold season the exhaust air heat is captured and transferred to the supply air stream which reduces the ventilation-generated heat losses.
Some condensate may form during heat recovery. The condensate is collected in the drain pan and is removed from the exhaust air duct.
In the warm season the intake air heat is transferred to the extract air stream. This allows for a considerable reduction of the supply air temperature which, in turn, reduces the air conditioning load.

The Freshbox 100 ERV WiFi units are equipped with a counter-flow energy recovery core with an enthalpy membrane at the core.

In the cold season the exhaust air heat and moisture are transferred to the supply air stream through the enthalpy membrane reducing the heat losses through ventilation.
Consequently, it is the intake air heat and moisture transferred to the extract 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.

PRE-HEATING
Freshbox E-100 WiFi, Freshbox E2-100 WiFi units are equipped with an electric pre-heater for freeze protection of the heat exchanger.

RE-HEATING
Freshbox E1-100 WiFi, Freshbox E2-100 WiFi units feature an electric re-heater to raise the supply air temperature as necessary.

FREEZE PROTECTIONFreshbox 100 WiFi features an exhaust air temperature sensor downstream of the heat exchanger which disables the supply fan to let the warm extract air warm up the heat exchanger. After that the supply fan is turned on and the unit reverts to the normal operation mode.
Overheating protection for Freshbox E-100 WiFi and Freshbox E2-100 WiFi is implemented with a pre-heater.

CONTROL

The unit is equipped with a control panel.The remote control is supplied as standardWi-Fi communication.

MOUNTING EXAMPLE

Each space requiring ventilation is equipped with one or several Freshbox 100 WiFi units.
A single unit is capable to ensure efficient ventilation in spaces with floor area up to 100 m².

Freshbox 100 WiFi 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 spigot (supplied as standard).
