Description
| USE Single-room energy-efficient supply and exhaust unit intended for decentralised ventilation of social and commercial spaces as well as apartments and houses.FEATURESEfficient solution for supply and exhaust ventilation of enclosed spaces.Electric preheating or post-heating is available for cold climate conditions.Modification with a heat exchanger equipped with an enthalpy core is available for humid and hot climate conditions.Low-energy ЕС fans.Silent operation (25-38 dB(A)).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.DESIGNPolymer 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 Ø100 mm pipes for fresh air intake and stale air extraction outside. The third Ø100 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 (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 %.The unit is equipped with supply and exhaust air dampers which activate automatically to prevent drafts while the unit is off.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 ЕН Freshbox 100 heater (purchased separately) to prevent icing.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 > 95 %) (purchased separately). Exhaust air is cleaned by the panel filter G4.  |
Freshbox E-100 units are equipped with an electric preheater which protects the heat exchanger from freezing.Freshbox E1-100 units feature an electric post-heater to raise the supply air temperature as necessary.The Freshbox 100 units are equipped with a counter-flow heat exchanger 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 units are equipped with a counter-flow heat exchanger 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 moisturetransferred to the extract air stream through theenthalpy membrane in the warm season. This allowsfor a considerable reduction of the supply air temperatureand humidity which, in turn, reduces the airconditioning load. |

| OPERATING PRINCIPLE
Operating principle with extra spigot for bathroom exhaust ventilation |
CONTROL 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. |
