• High-efficient EC fans, backward-curved, external rotor. Low power consumption at any speed, low noise level and stable operation in any climate conditions.
• Integrated plug-and-play controls on the basis of the Carel kVent. controller. Easy connecting via web-interface using the Ethernet-Modbus and BACnet.
• Insulated double-skin frameless casing.
• High-efficient counter-flow heat exchanger is made of profiled aluminium plates and impregnated with elastic heat-resistant sealant.
• The stainless steel drain pan is located on the inlet and outlet sides.
• The casing panels are made of steel with zinc-aluminium coating and internally lined with 40 mm heat- and sound-insulating mineral wool layer. The units have C4 corrosion resistance class in compliance with ISO 12944. Each model is available in left- and right-handed modifications. The units have service access on both sides and on the bottom.
• Washable F7, G4 (optional) panel filters in exhaust and supply air streams.
• Integrated control panels:
  • A30 th-Tune: standard control panel with handy interface ensures basic setup of parameters.
  • A32 pGDe: control panel with expanded functionality ensures complete setup of parameters.
• Integrated 100 % bypass of the heat exchanger with automatic damper and Belimo actuator ensures active freeze protection. Free heating and cooling functions are also available. Built-in automatic external air dampers with Belimo actuators.
• ECO-Design’18 compliant.

• Supplied units come with “Plug-&-Play” control system based on Carel programmable controller. Depending on the unit configuration, the system is fitted with 3 temperature sensors: outside, supply, and exhaust air temperature; return water temperature sensor and frost protection relay for water heater configuration; overheating protection relay for electric heater configuration. Standard controller outputs allow to connect various additional sensors. The list of the optional sensors may be found in the accessories section.
• Plug-and-play control system is fitted with Carel th-Tune control panel which ensures basic setting options and has user friendly interface. Carel PGDe extended control panel may be fitted on request and provides more flexibility and sophisticated control adjustments. The compact dimensions and elegant design make both suitable for all types of premises.

• Operation in comfort, precomfort or economy mode.
• Temperature control.
• Weekly schedule setting: holiday and special day functions, selection of up to four daily time bands with settings for each operating mode.
• Coils and heat exchanger auto protection.
• Air pressure control, air flow and humidity control (with optional sensors).
• Air quality control (with optional CO₂/IAQ sensors.
• Freecooling or freeheating mode (according to model).
• Pumps control, overload alarms and anti-blocking for each pump (according to model).
• MODBUS supervisor protocol and user friendly WEB-interface via Ethernet port.
• PGDe panel’s extended settings.
• Parameters settings divided by level (user, installer or manufacturer) with password-protected access.
• 3 adjustable fan speeds.
• Priority to temperature or humidity control by room/supply/extract sensors.

heat-resistant sealant. The sealing provides a reliable separation of the

supply and exhaust air, eliminating internal flows, and not allowing moisture,

dirt, odors and microorganisms transfer between streams. Bypass channel

on heat exchanger with automatic Belimo actuator provides active frost

protection, freeheating and freecooling functions. Drain pan is installed under

the heat exchanger on both supply and exhaust sides.

The advantages of this type of fan are: extremely low power consumption at any speed,

no need for external speed control and compact size due to motor with external rotor.

• Better thermal resistance.
• Lower weight of the unit.
• No thermal bridges.
• Suitable for outdoor installation in cold climate.
• High mechanical strength.
