Blauberg Freshbox 100 ERV

Electric preheating or reheating is available for cold climate conditions.Units with enthalpy heat exchangers are available for use in hot and wet climates.Low-energy EC motors.Silent operation.Supply air purification ensured by two built-in G4 and F8 filters (optionally H13).Upgradeable with an exhaust duct to provide air extraction from the bathroom.Easy installation.Compact size.

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 ∅ 100 mm pipes for fresh air intake and stale air extraction outside. The third ∅ 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-ofthe- 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 %.

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

Supply air cleaning is provided by the G4 and F8 panel filters (PM2.5 > 75 %). To meet more stringent air purity requirements the F8 filter can be replaced with an H13 (PM2.5 > 99 %) (purchased separately). Exhaust air is cleaned by the panel filter G4.

PREHEATING

Freshbox E-100 units are equipped with an electric preheater which protects the heat exchanger from freezing.

HEATER FOR CONDENSATE FREEZE PROTECTION

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 EH Freshbox 100 (optional) heater (purchased separately) to prevent icing.

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.

	Operating principle with extra spigot for bathroom exhaust ventilation

The unit is equipped with a control panel.The remote control is supplied as standard.

FUNCTIONS

FREEZE PROTECTION

There are two types of freeze protection available to protect the heat exchangers in the cold season.Freshbox 100 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.The Freshbox E-100 units are equipped with an electric preheater 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.

Each space requiring ventilation is equipped with one or several Freshbox 100 units.A single unit is capable to ensure efficient ventilation in spaces with floor area up to 75 m².

Freshbox 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 ∅ 100 mm spigot (supplied as standard).
