- 3E - Concept
- 2 Stage Heat/Cool
- All in 1
- 100% Factory tested
- 100% Plug and play
1е - Every Climate – from -25°C to +60°C
2е - Every Application – suitable for every application where 100% fresh air is needed, by means of covering all possible air treatment processes:
Recirculation – 0÷100%
Cooling + Dehumidification
3е - Every Installation - suitable for all types of mounting, indoor (machinery rooms, technical floors, etc.) and outdoor
Recovering up to 100% of the extract heating/cooling, achieved - "consecutively" in 2 stages:
1st stage - the sorption rotary heat exchanger, recovers more than 70% of the heatig/cooling and humidity.
2nd stage -the evaporator/condenser of the air to air heat pump, recovers the rest up to 100%.
A multifunctional concept solution for fresh air (as well as for covering heating losses and cooling loads at once), which can practically solve entirely the need for Air-Conditioning, Ventilation and Heating at the project site by using only air as fluid. Thus, radiators/fan coils/cassettes, boilers, chillers/VRF systems, pipes, insulations, pumps, fittings, etc., are no longer required. It only needs a duct system, - (which already exists in every conventional system) - and the correct designing of the necessary air quantity.
High reliability and reduced installation costs, achieved by 100% factory tests - each unit is tested under factory conditions.
The test includes:
- Leakage check
- Vacuuming and loading the system with the exact refrigerant quantity
- Functional testing of all fans and compressors
- Loading the controller's software
- Temperature and pressure checks
- Setting up the required air flow
- Recording all parameters of the unit on a test list
A standalone "one-piece" unit, which only needs a duct system and power supply for its start up.

Everything you need to know about the machine’s components
The solutions from the max.e3 series are designed and manufactured in accordance with EN 1886 – (Ventilation for buildings-Air handling units Mechanical Performance).Learn more
max.e3 is designed as a system with the structure of the unit, manufactured as a mono-block (from size max.e3-02 to size max.e3-18. Bigger sizes like max.e3-25, 30, 35 are produced on sections) consisting of aluminium profile, supporting elements, connection angles and locking accessories.
Rotary heat exchangerAll of the max.e3 units use an air-to-air rotary heat exchanger- Sorption type, made from aluminium foil and 3Å molecular sieve, which gives high sensitivity for absorbing water molecules (HM1 type). Sorption rotors provide an excellent method to pre-cool and dehumidify the fresh air before entering the DX cooling coil. Temperature efficiency (Sensible) – E ≥ 70%, Humidity Efficiency – E ≤ 80%.Learn more
100% DX unitLearn more
No additional water, electric or DX heating/cooling coils are needed in the max.e3, which makes it independent of other additional heating/cooling sources (boilers, chillers, VRF systems, etc.)
Fansmax.e3 use ZAbluefin plug fans with latest EC Blue (Electronically Commutated) from Ziehl-Abegg. Fan wheel statically and dynamically balanced on the axis of the direct-driven motor. Fan wheel, together with the motor, is mounted on a common base frame with vibration dampers.Learn more
max.e3 is fully equipped with all necessary automation and all executive mechanisms. The electric switchboard is integrated into the unit and located on the operation side.Learn more
The "Brain" of max.e3 is its specially designed by Damvent controller, which controls and manages all processes and protects the unit from eventual cut-offs.
Connectivity and mobility
All hybrid units allow into the corresponding connector of the ICB controller to be mounted specialized internet circuit board for internet connection. The built-in circuit board allows a permanent internet connection to max.e from any location in the world. This option helps you/us to make adequate reaction to situations requiring fast and accurate solutions to the problem.Learn more
Filters are installed at the entrance of the unit to ensure the normal operation of the AHU and to prevent contamination of the components.Learn more
Microcell filters are used in the units max.e3. These filters are made of plated micro-glass paper and spaced with hot melt adhesive beads, which are uniformly positioned to deliver optimum airflow.
AdvantagesLearn more about what you will save by using our hybrids
- Initial investment costs
- Installation costs and labor
- Installed electric power
- Energy and exploitation costs
- Service and Maintenance costs
In comparison to conventional HVAC equipment, max.e3 reduces the investment costs by removing the need for: radiators/fan coils/cassettes, boilers, chillers/VRF systems, pipes, insulations, pumps, fittings and morе.
Beeing 100% Factory tested and 100% Plug and Play max.e3 reduces significant part of the labor costs.
max.e3 can reduce up to 30% the necessary installed power for HVAC system. In some cases even more.
Providing COP/EERnet = 5÷15, ensures the lowest possible energy costs for HVAC (EUR/kWh).
Maintaining only one unit instead of several, reduces significantly the maintenance cost. Filters are the only components that need to be checked, cleaned and replaced.
It saves time in designing, installation works, start-up and commissioning, service and maintenance, etc...
Whether it's installed indoor or outdoor, the absence of separate (VRF/Chiller), additional pipes, provide "clean roofs" for the buildings.
Significantly reduces the costs for a BMS system regarding its HVAC part.
