max.e-mini - “e-conomizer” with “2 stage thermodynamic heat recovery technology”- recovering up to 100% of the extract heat from the room. 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.

  • Hybrid HVAC solution
  • 2 stage thermodynamic heat recovery technology
  • All climate zones from -20oC to +40oC

- Every Climate – from -20°C to +40°C
- Every Application – suitable for every application where 100% fresh air is needed, by means of covering all possible air treatment processes:

  • Filtration
  • Recirculation
  • Heat recovery
  • Heating
  • Cooling

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

2 stage thermodynamic heat recovery technology

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 55÷60% of the extract heat from the room

2nd stage - "active heat recovery" - using the evaporator of the air-to-air heat pump to recover between 45÷40% of the extract heat from the room

All in 1

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

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 the test list

100% Plug & Play

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

  • 3 е - concept
  •  2 stage thermodynamic heating recovery
  • All in 1
  • 100% factory tested
  • 100% Plug & Play

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 -10oC, -15oC or even -20oC. Extracting heat from the ambient air is an inefficient process.

max.e-mini uses a plate air-to-air heat exchanger made from aluminum fins with a condensate drain pain and a mounted motorized damper (bypass and "free-cooling"). 

Efficiency (Sensible) – E ≤ 65÷70%

The plate heat exchanger is EUROVENT certified - Certificate: 03.01.242.

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

max.e-mini 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.e-mini ensures the highest IE4 Premium Efficiency and ErP conformity- 2015/EC controller integrated
