Automation system

max.e 3- DH 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. The "Brain" of max.e3 is specially designed by Damvent controller, which controls and manages all processes and protects the unit from eventual cut-offs.

Rotary heat exchanger

All of the max.e 3-DH units use an air-to-air rotary heat exchanger- Sorption type, made from aluminium foil and a 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 - E ≤ 80%

Heat pump

100% DX unit. No additional water, electric or DX heating/cooling coils are needed in the max.e 3-DH, which makes it independent of other additional heating/cooling sources (boilers, chillers, VRF systems, etc.)

Additional DH Re-heater

The additional re-heater is an integral part of the refrigerant circuit and recovers heat. The re-heated air is supplied with the desired parameters (e.g. T/RHsupply = 18°C/50%) without using any electric or water source.

Fans

max.e 3-DH use ZAbluefin plug fans with the latest EC Blue (Electronically Commutated) from Ziehl-Abegg. The fan wheel is statically and dynamically balanced on the axis of the direct-driven motor. The fan wheel and the motor are mounted on a common base frame with vibration dampers.

Integrated steam humidifier

During the winter season, we recover up to 85% of the extract RH(%) from the room, but still, an additional steam humidifier must be implemented into the max.e3-DH to reach the necessary Rhroom(%) or to produce the required humidity when the unit is being started up. The humidifier could be fully integrated within the unit or installed within the building, but in both cases controlled by our ICB.

achieved - "consecutively" in 3 stages:
1st stage - Cool / Humidity Recovery in the rotary wheel +

2nd stage - deep cooling and dehumidifcation in the evaporator +

3rd stage - re-heating by the additional re-heater (condenser) in summer, spring and autumn seasons and 1.Heat/Humidity recovery by the rotary wheel + 2.Heating by the Condenser + 3.Humidification by the Steam Humidifier in the winter season.

max.e - multifunctional concept solution for fresh air with built-in reversible heat pump and integrated automation system.

High reliability and reduced installation costs, achieved by 100% factory tests - each unit is tested under factory conditions
The factory 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

Stand alone "one-piece" unit, which only needs a duct system and power supply for start up.

COP/SCOP/SPF

Higher than the highest standards!
A conventional air-cooled heat pump uses the ambient air for the evaporation process, and during the winter, this air can reach temperatures of -10°C, -15°C or even -20°C. Extracting heat from the ambient air is an inefficient process. In comparison, max.e3 uses the extract air from within the room.

Hardware

Everything you need to know about the machine’s components

  • Design

    The solutions from the max.e3 - DH series are designed and manufactured in accordance with EN 1886 – (Ventilation for buildings-Air handling units Mechanical Performance).
    max.e3-DH is designed as a system with the structure of the unit, manufactured as a mono-block (from size max.e3-02 DH to size max.e3-18 DH. Bigger sizes like max.e3-25, 30, 35 DH are produced on sections) consisting of aluminium profile, supporting elements, connection angles and locking accessories.

    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.e3-DH  from any location in the world. This option helps you/us to make adequate reactions to situations requiring fast and accurate solutions to the problem.
