  • 100% PLUG AND PLAY

1e - Every Climate – from -30°C to +55°C

2е - Every Application –suitable for every application where 100% fresh air is needed, by means of covering all possible air treatment processes:
Recirculation 0÷100%
Heating
Cooling + Dehumidifcation
Process Ventilation.

3е - Every Installation - Every Installation - suitable for all types of installation, indoor (plant rooms, technical floors, etc.) and outdoor.

Recovering up to 120% of the extract heating/cooling, achieved "consecutively" in 2 stages:

1st stage - "passive heat recovery" - using an air-to-air plate heat exchanger to recover up to 65 - 70% of the extract heat/cool from the room.

2nd stage - "active heat recovery" - using the evaporator of the air-to-air heat pump to recover from 65-120% of the extract heat from the room.

The max.e tHVAC is an air-to-air packaged heat pump 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 factory test includes:
· Refrigerant Leakage check
· Vacuum test and loading the system with the exact refrigerant quantity
· 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 operation.

Performance

Take a look at the improved technology

  • max.e technology Space Cooling and Space Heating unit using 100% fresh air, with no recirculation air, nor indoor units. By providing a min.air change rate and with the Free-Cooling mode, the unit will maintain Troom during intermediate seasons (spring and autumn with Tambient ≥ 10oC and ≤ 20oC), which form 30-40% of the total annual working hours) , only by using Free-Cooling and Ventilation,
  • without compressor`s working. That`s a high energy saving feature, that cannot be achieved elsewhere. At design ambient/room conditions (-15oC) COPnet for heating mode of the unit (incl. HR and all fans) reaches: COPnet = 7,64, Which is a value not possible for all classic air-to-air heat pumps and VRF`s

COP/SCOP/COPnet

Higher than the highest standards!
The conventional air cooled heat pumps use 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 inefficient. In comparison, the max.e-tHVAC uses the extract air from the room. Under normal conditions, this air ranges in temperatures from 20-24°C. Firstly, 60-65% of the heat is recovered in the plate heat exchanger and then with a positive temperature between +1-7°C, the air enters the evaporator of the heat pump, thus recovering the remaining 30-35%. In this way, we extract up to and more than 100% of the heat from the extract air.

Advantages

  • For End Users
  • For Designers
  • For Installation Companies

· It completely removes the need of the traditional cooling/heating system-split, multisplit, VRF, pipes etc. With just a duct system (increased size (5h-1), compared to the traditional 2-2,5h-1) and power supply the end user gets total HVAC system.

· No internal units (cassettes, fan coils etc.), no pipes inside the room(s). Only ducts and grilles.

· No condensate lines and wires inside the room(s).

· No refrigerant inside the room(s).

· 100% Plug&Play packaged unit.

· Saves space and footprint – with almost the same size as the traditional ventilation unit, the end user gets much more free space.

· Saves installation time and costs.

· Saves designing time and costs – much simpler design – only duct system and grilles.

· Lower initial installed electric power and energy consumption, due to the lack of electric heater for reheating of fresh air (which is part of the ventilation unit in the classic system), and due to use of free-cooling and ventilation for Troom control in the intermediate modes (spring, autumn with Tambient≥10oC and ≤20oC).

· Saves service time and costs- it requires almost the same service efforts as the standard ventilation unit. There`s only 1 company responsible for the service, unlike the classic system (where usually 1 company is dealing with the ventilation unit and another one with the split/multisplit/VRF).

· Better comfort for the occupants in the rooms, due to 100% fresh air supply at all times. No risk of infections.

· More flexible installation position, depending on project availability (outdoor or indoor, vertical or horizontal).

· Easy to move the unit to another project of the end user if necessary.

It saves time – almost manual design with no need of specialized software for the equipment.

· Easy installation on site (needs only connection to the ducts system and power supply).
· Connection to the BMS system through different protocols.
· Setting up the unit through Internet.
· Lack of working with refrigerants on site.

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
