VEX200

VEX200 is a range of energy-friendly air handling units with rotary heat exchangers and EC motors. You can choose between two rotor types, standard and high efficiency. Choose ALC™ when you want to ensure a good indoor climate. ALC™ allows you to transfer humidity while eliminating recirculation of particles, aerosols, viruses, etc. The many versions of the VEX200 range permit a high level of flexibility in installation and location as you can choose spigot location in the units end, top and bottom.

The units are delivered with integrated control systems, that are accessed via the connection box on the front of the air handling unit.

VEX200 air handling units are supplied either as a complete air handling units (VEX240-250) or sectional units (VEX260--280).

Functioning principles

The VEX 200 brings fresh, filtered air into the building and recovers heat from exhaust air using its high-efficiency heat exchanger. The incoming air can be heated and/or cooled using a comprehensive range of coils.

Main features

The ALC™ (Automatic Leakage Control) option is the patented solution that prevents the propagation of viruses by air handling units equipped with rotary heat exchangers. It measures, checks and constantly adjusts the pressure difference between supply and return airflows to ensure that no stale air comes into contact with the clean air produced by the unit.

The aluminium rotary heat exchanger with low pressure drop and a temperature efficiency of 80%.

The rotor control comprises a step motor with motor control.

Efficiency:

Rotor with wave height of 1.4 mm - very high efficiency
Rotor with wave height of 1.8 mm - very high efficiency

The combination of modern EC motors and the EXHAUSTO motor controller delivers extremely low energy consumption and with the EXstream impeller, a high output is achieved.

An energy label that states the energy class of the air handling unit in relation to defined operating conditions is available via our product calculation programs.

MECHANICAL PERFORMANCE:

According to DS/EN 1886 and certified by Eurovent:

Casing strength: D1 (M)
Airtightness under negative pressure at -400 Pa: L1 (M)
Airtightness under positive pressure at +700 Pa: L1 (M)
Filter bypass leakage: F9 under negative and positive pressure
Thermal transmittance: T2 (M)
Thermal bridging factor: TB3

The cabinets are made from Aluzink AZ185 class C4 and insulated with 50 mm mineral wool. This results in low noise emissions to the external environment/installation location.

The panel construction minimizes the formation of thermal bridges in the air handling unit.

The motor sections are mounted in vibration dampers, which reduces noise in the ducts and eliminates the need to fit flexible connections between the unit and the duct system.

The motor sections can be pulled out for easier servicing.

The motors are of type EC and are extremely efficient. They comply with the requirements of the Ecodesign Directive.

EXstream performance:

The units are equipped with EXHAUSTO EXstream impellers, one of the leading air fan impellers on the market in terms of low energy consumption and low sound level.

The fan impeller rpm and the number of vanes have been optimised so that the “vane frequency” is in the 500 Hz band. This means that fewer/smaller silencers are required than normal and it costs less to sound proof at frequencies of 500 Hz than it does with frequencies of 125/250 Hz (the typical range).

The easily accessible connection box with built-in switch disconnector and control system fuses ensures easy access for connecting and service.

The mounting base has feet with an adjustable height.

The base is an accessory for VEX240/250, but standard on the other models, where the unit is assembled at the bottom by using the base, and via trunk fasteners at the top.

VEX200 series can be supplied with panel filters and bag filters.

Filter class in acc. with EN779:

Panel filters: Coarse 85% (M5) or ePM1 55% (F7)

Bag filters: ePM10 60% (M5) or bag filters ePM1 60% (F7).

With some projects, limited space means that internal transport of the air handling unit is difficult or impossible. This is why the VEX200 is available as a split version. It means that the air handling unit can be assembled and tested at the factory as normal – just without sealant. The air handling unit can therefore be easily taken apart at the installation site, transported as single sections, assembled, sealed and commissioned.

EXact2 control system:

- 0–10 V
Configuration and monitoring via:
- Wired remote control
