DamVent Ltd

max.e3 – economiser, a multifunctional concept solution for fresh air.

1e – Every Climate, from -25degC to +60degC.

2e – Every Application, suitable for every application where 100% fresh air is needed by covering all possible air treatment processes.

3e – Every Installation, suitable for mounting internally or externally.

The solutions from the max.e3 series are designed and manufactured in accordance with EN 1886 – (Ventilation for buildings-Air handling units Mechanical Performance).

Microcell filters are used in the units. These filters are made of pleated micro glass paper and spaced with hotmelt adhesive beads which are uniformly positioned to deliver optimum airflow. The frame is constructed from a composite material and 130mm Galvanized steel sheets. The class of filtration is F6 (standard), F7, F8 and F9 (optional).

Sorption rotors provide an excellent method to precool and dehumidify the fresh air before entering the DX cooling coil. Molecular Sieve (HM1) 3Å sorption wheels give exceptional high humidity transfer efficiencies. In general, humidity efficiency is more or less equal to temperature efficiency.

The refrigerant circuit contains 1 or 2 circuits, depending on the size of the unit. The refrigerant used is eco-friendly R407C. A quantity of 1, 2 or 4 Scroll compressors are used depending on the size of the unit. All of the units contain high efficiency direct expansion coils which are made from copper tubes and aluminium fins and are equipped with a condensate drain pan.

Units use EC Blue (Electronically Commutated) Plug Fans with Ziehl-Abegg type Cpro frequency inverters. Fan wheels are statically and dynamically balanced on the axis of the direct-driven motor and mounted together on a common base frame with vibration dampers.

Each unit is fully equipped with all necessary controls. The brain of the unit is its controller which controls and manages all processes and protects the unit. The software is developed with a high level of know-how and it controls all processes. Only the parameters (temperature and relative humidity) of the room need to be input. The controller chooses which process to work in depending on the variables input for the outside temperature, the set point temperature, and the supply and room temperatures.
