MAX.E-MINI

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.

- 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.

COP

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.

HARDWARE

DESIGN

max.e-mini is a single "1 piece" (standalone) unit consisting of aluminum profiles, fastenings and connecting angles.

Side Panels single skin, manufactured from 1.2 mm galvanised sheet steel mounted to supporting columns with bolts. Side panels are internally lined with sound insulation material only.

PLATE HEAT EXCHANGER

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.

HEAT PUMP

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.)

FANS

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

AUTOMATION SYSTEM

max.e-mini 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.e-mini is a controller which controls and manages all processes and protects the unit from eventual cut-offs.
