MAX.E3

max.e3 - "e-conomizer" with "2 stage thermodynamic heat recovery technology"- recovering up to 100% of the extract heat/cool/humidity. It is designed to maintain the indoor climate whenever 100% fresh air is needed. Typical projects include cinemas, theaters, discos, restaurants, museums, casinos, banks, hotels, airports, office buildings, shopping malls, hospitals and production areas.

3е-concept

- Every Climate – from -25°C to +60°C
- 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

- Every Installation - suitable for all types of mounting, indoor (machinery rooms, technical floors, etc.) and outdoor

2 stage heating/cooling/humidity recovery technology

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%.

All in 1

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.

100% factory tested

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 a test list

100% Plug & Play

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

COP/SCOP/SPF

Higher than the highest standards!

According to EN14825, the highest Energy Efficiency Class for Heat Pumps is A+++ with a SCOP=3,75 (high temperature) -4,38 (low temperature). With a SCOP=3.8÷6.5 (of the refrigerant circuit) and a COPnet of the whole system SCOPnet= 5÷15 , max.e3 is far ahead of the competition.

ROTARY HEAT EXCHANGER

For all of the units of the type max.e3 are used air-to-air rotary heat exchanger - Sorption type, made from aluminum foil and  molecular sieve which gives high selectivity for absorbing water molecules (HM1 type). Sorption rotors are providing an excellent method to pre-cool and dehumidify the fresh air before entering DX cooling coil. Temperature efficiency (Sensible) –E ≥ 70%, Humidity Efficiency – E ≤ 80%.

HEAT PUMP

100% DX unit

No additional water, electric or DX heating/cooling coils are needed in the max.e3, which makes it independent to other additional heating/cooling sources (boilers, gas, chillers, VRF systems, etc.)

FANS

max.e3 use EC Blue (Electronically Commutated) Plug Fans - with EC Drive Technology and direct driven wheel Cpro from Ziehl-Abegg. The wheels made of high-performance ZAmid composite Material in one-shot injection moulding process, so it does not have any welded seams or critical connections.

This shape alone produces higher efficiency, enabling performance which saves up to 15% energy during operation.

Using EC Blue fans max.e3 ensures the highest IE4 Premium Efficiency and ErP conformity- 2015/EC controller integrated

AUTOMATION SYSTEM

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.
The "Brain" of max.e3 is a controller which controls and manages all processes and protects the unit from eventual cut-offs.

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.e3. These filters are made of plated micro glass paper and spaced with hotmelt adhesive beads which are uniformly positioned to deliver optimum airflow.
