  • 3E - Concept
  • 2 Stage Heating/Cooling Recovery
  • All in 1
  • 100% Factory tested
  • 100% Plug and play

1е - Every Climate – from -20°C to +40°C

2е - Every Application – suitable for every application where 100% fresh air is needed, by means of covering all possible air treatment processes:

    Filtration
    Recirculation – 0÷100%
    Heat recovery
    Heating
    Cooling + Dehumidification
    Proces Ventilation

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 - "passive heat recovery" - using air-to-air plate heat exchanger to recover up to 65÷70% of the extract heat from the room

2nd stage - "active heat recovery" - using the evaporator of the air-to-air heat pump to recover from 65÷100% of the extract heat from the room

The max.e2 is an autonomous module heat recovery ventilation unit containing an biult-in heat pump, automation, and a control system.

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
  - Vibrations
  - Loading the controller's software
  - Temperature and pressure checks
  - Setting up the required air flow
  - Recording all parameters of the unit on the test list

A standalone "one-piece" unit, which only needs a duct system and power supply for its start up.

Performance

Take a look at the improved technology

  • Possibility for increased Tsupply at lower ambient temperature in winter mode, due to especially designed booster mode
  • Less maintenance regarding the plate heat exchanger compared with the Rotary heat exchanger
  • More compact design
  • Lower refrigerant content compared to the classical systems
  • Stepless Capacity Control

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.e2 uses the extract air from within the room.

Hardware

Everything you need to know about the machine’s components

  • Design

    max.e2 is designed as a system with the structure of the unit, manufactured as a mono-block. The construction is manufactured from high quality profiles made of extruded aluminum characterized by high strength and resistance to adverse weather conditions.

  • Plate Heat Exchanger

    Plate Heat Exchanger

    For all of the units of the type max.e2 are used plate air-to-air heat exchanger, made from aluminum fins - “epoxy” coated, with condensate drain pain. This special cover of the plate heat exchanger allows extending their useful life and also their best levels of performance for a long time.

  • Heat Pump

    100% DX unit 
    No additional water, electric or DX heating/cooling coils are needed in the max.e2, which makes it independent to other additional heating/cooling sources (boilers, chillers, VRF systems, etc.)

  • Fans

    Fans

    max.e2 use ZAbluefin plug fans with latest EC Blue (Electronically Commutated) from of the company Ziehl-Abegg. Fan wheel statically and dynamically balanced on the axis of the direct-driven motor. Fan wheel together with the motor are mounted on a common base frame with vibration dampers.

  • Automation System

    max.e2 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.e2 is its specially designed by Damvent controller which controls and manages all processes and protects the unit from eventual cut-offs.

     Automation System
  •  Connectivity and mobility

    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.

  • Filters

    Filters are installed at the entrance of the unit to ensure normal operation of the AHU and to prevent contamination of the components.
    Microcell filters are used in the units max.e2. These filters are made of plated micro glass paper and spaced with hotmelt adhesive beads which are uniformly positioned to deliver optimum airflow.

Advantages

  • Initial investment costs
  • Installation costs and labor
  • Installed electric power
  • Energy and exploitation costs
  • Service and Maintenance costs
  • Time
  • Space
  • BMS


In comparison to conventional HVAC equipment, max.e2 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.e2 reduces significant part of the labor costs.

max.e2 can reduce up to 30% the necessary installed power for HVAC system. In some cases even more.category an action comes under.

Providing COP/EERnet = 4÷10, 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.

Traditional Systems
  • AHU with DX/water section
  • Outside mounted air-cooled heat pump
  • Boiler for the water systems – for working on very low outside temperatures
  • Pipes, fastenings, isolation, etc.
  • Pumps (for water systems)
  • Extra Labor
  • Common automation and controlling system
  • Higher installed power electricity capacity – higher costs for wiring
  • Higher BMS costs – two or more systems
  • More space for installation
