Description
FEATURES  
  • Efficient decentralized ventilation unit for small offices or conference rooms.
  • Visible ceiling suspended installation.
  • A version with electrical preheater is available for cold climate.
  • Clean air due to the use of an ePM1 70% / F7 filter for supply air filtration.
  • Possibility to connect fresh air inlet and exhaust air ducts at top or back side of the unit.
  • Low noise operation from 16 dB(A) at 3m.
  • High level of comfort due to builtin bypass and air dampers.
CASING PREHEATING
  • The casing is made of galvanized sheet metal with white painted decorative cover.
  • The contemporary design of the Uni Max unit will seamlessly blend into any interior.
  • The unit is heat- and sound-insulated with a 20 mm layer of foam.
  • The service panel is easy to open for filter maintenance.
  • The unit is equipped with two Ø125 mm spigots for fresh air intake and stale air exhaust.
  • The position of the spigots can be changed from horizontal to vertical.
  • The Uni Max E S21 units are equipped with an electrical preheater to prevent heat exchanger freezing in the cold climate.
BYPASS
  • The Uni Max units are equipped with a bypass for summer cooling by the cool air from outside.
AIR DAMPERS HEAT RECOVERY
  • The Uni Max unit is equipped with two automatic air dampers, which close automatically when the unit is off to prevent drafts.
  • The Uni Max unit is equipped with a plate counter-flow polystyrene heat exchanger for heat recovery. The unit condensate is collected and drained to the drain pan under the heat exchanger.
  • The Uni Max E unit is equipped with an enthalpy plate counter-flow heat exchanger for energy (heat and humidity) recovery. Due to humidity recovery condensate is not generated in the enthalpy heat exchanger.
  • The air flows are completely separated in the heat exchanger. Thus smells and contaminants are not transferred from the extract air to the supply air.
  • Heat recovery is based on heat and/or humidity transfer through the heat exchanger plates.
  • In the cold season supply air is heated in the heat exchanger by transferring the heat energy of warm and humid extract air to the cold fresh air. Heat recovery minimizes ventilation heat losses and heating costs respectively.
  • In the warm season the heat exchanger performs reverse and intake air is cooled in the heat exchanger by the cool extract air.That reduces operation load on air conditioners and saves electricity.
FANS
  • The units feature high-performance, electronically commutated (EC), external rotor motors with forward curved blades.
  • These state-of-the-art units offer excellent energy efficiency.
  • In addition to that, EC motors combine high performance and optimum control over the entire speed range.
  • EC motors have an excellent power efficiency (up to 90 %).
AIR DISTRIBUTION  
CONTROL AND AUTOMATION  
  • The Uni Max А21 units are equipped with an integrated automation system. The remote control panel is not included in the delivery set (sold separately).
  • The А21 controller allows integrating the unit into the Smart Home system or BMS (Building Management System).
  • Unit control via Wi-Fi using the mobile application Vents AHU. The Uni Max А14 units are equipped with an integrated automation system and the А14 wall mounted sensor control panel with LED-indication.
