Ventilation units for efficient supply ventilation in various premises.Controllable air supply, heating and filtration.Compatible with 400x200 up to 800x500 mm rectangular air ducts.
The casing is made of double-skinned aluzinc panels, internally filled with 25 mm mineral wool layer for heat and sound insulation.The casing has fixing brackets with vibration absorbing connectors for easy installation.The hinged casing side panel ensures easy access to the internals for cleaning, filter replacement and other maintenance operations. Asynchronous external rotor motor and centrifugal double-intake impeller with forward curved blades is used for air supply.Single- or three-phase motor modification depending on the fan model type.Integrated motor overheating protection with automatic restart.Dynamically balanced impeller.Equipped with ball bearings for longer service life.Reliable and quiet operation.

The units are equipped with a water (glycol) heater for operation during cold seasons at low outside temperature.The air temperature sensor downstream of the water heater and the return heat medium sensor ensure freezing protection of the water heater. If any of these sensors detects a temperature point below the set minimum value, the signal is sent automatically to the control unit to troubleshoot cooling.AIR FILTRATIONThe built-in G4 supply filter provides air filtration.MOUNTINGThe unit is suitable for mounting on the floor, ceiling mounting or wall mounting with fixing brackets in any mounting position except for the vertical one with air flow downwards.The correct mounted unit must provide free access to the hinged panel for servicing and filter replacement. The units incorporate an integrated control system with a wall-mounted control panel and LCD display.The standard delivery set includes a 10 m cable for connection of the unit and the control panel.Control panel functions:
  • Activating/deactivating the unit.
  • Setting low, medium and high speeds for the supply fan. Air flow control.
  • The models with a water mixing unit have the function of setting and maintaining the supply air temperature by means of controlling the heat medium control valve.
Automation functions:
  • Supply air temperature control by means of controlling the heat medium control valve.
  • Control of the supply air damper actuator (separate order).
  • Control of the external circulation pump on the heat medium feed line.
  • Regulation of heat medium flow in the water heater in case of the differential pressure of the return heat medium below 40 kPa.
  • Water heater freezing protection with the mixing unit and the circulation pump.
  • Control of the cooler with respect to the set indoor air temperature (separate order).
  • Supply fan control.
  • Supply filter clogging control.
  • Shutdown of the unit on signal from the fire alarm panel.

The air flow is 1500 m³/h and the air speed in the cooling unit is 3.5 m/s ➀.To calculate the maximum air temperature find the intersection point of the air flow line ➀ with the rated outer temperature shown in blue line (e.g., -25 °C) and draw the line ➁ to the left until it crosses the water in/out temperature curve (e.g. +70/+50). From this point draw a vertical line to the supply air temperature downstream of the heater (+30 °C) ➂.To calculate the heater power find the intersection point of the air flow ➀ with the rated winter temperature shown in red line (e.g., -25 °C) and draw the line ➃ to the right until it crosses the water in/out temperature curve (e.g. +70/+50). From this point draw a vertical line to the heater power axis (33.0 kW) ➄.
To calculate the required water flow in the heater prolong this line ➅ downwards to the water flow axis (0.42 l/s).To calculate the water pressure drop in the heater find the intersection point of the line ➅ with the pressure loss curve and prolong the line ➆ to the right on the water pressure drop axis (10.0 kPa).
