VEX200EC (EXact2) Compact air handling units

 

General

VEX200 series

VEX200 is a range energy-friendly air handling units with rotary heat exchangers and EC motors. You can choose between two rotor types, standard and high efficiency.

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. Read more under Variations.
The units are delivered with integrated control systems, that are accessed is the connection box on the front of the unit.
VEX200 units are delivered either as a complete unit (VEX240-250) or split into sections (VEX260-280).

Operating conditions

In principle, EXHAUSTO VEX units are designed for use in comfort ventilation - i.e. under ordinary operating conditions.

Where ventilation solutions are required for rooms with high air humidity - e.g. due to humidification, we recommend you make a test calculation with one of our calculation programs. If the calculation shows a risk of condensation after the heat exchanger, an assessment must be made whether the operating conditions can be changed, or whether the unit must be modified to allow condensate to drain off. This is particularly relevant for VEX100CF.

Contact EXHAUSTO for advice on this.

Sound

VEX200, low-noise air handling units

All of the VEX200 series of air handling units are low-noise and their associated cooling and heating coils are also sound proofed.
For exact sound data, see our calculation programs.
Design

VEX200 design

The compact air handling units are designed in accordance with the German hygiene norm VDI6022, which ensures a unit accessible for service, and where fungus or bacteria are not formed which may reduce air quality. Read more about this standard under certificates at the bottom of the page. 


Enclosures

 
Kabinet_VEX200

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.


Motor sections

 

EC-motor_MC

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.


Fan impeller

 
EXstream ventilatorhjul

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).


AHUC Mainboard

 
EXact2 The easily accessible  connection box with built-in switch disconnector and control system fuses ensures easy access for connecting and service.

Filters

 
Pose og kassefiltre

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). 

Pre-filtering with cassette filter on the supply air side

Double filter for VEX200

It is now possible to insert 2 48 mm filters instead of 1 96 mm filter in VEX200 on the supply air side. By inserting a coarser filter in front of a finer filter, the accumulation of debris in the finer filter can be reduced. Depending on the outdoor air and the desired quality of the supply air, this can be a good idea/option.

The filters (48 mm) are available in the classes: Coarse 60% (G4), ePM10 80% (M5), ePM1 50% (F7) and ePM1 80% (F9).

A pressure drop, etc. can be calculated in the product selection programme EXselect.

 

 


Mounting base

 
VEX200_sokkel

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.


Energy

VEX200 Energy efficient ventilation

In the design of the unit, much attention has been paid to ensuring that the air-flow through the air handling units takes place as smoothly as possible, to keep pressure loss as low as possible.


Rotary heat exchanger

 
 
Roterende veksler 

Aluminium rotary heat exchanger with low pressure loss and a temperature efficiency of 80%. The rotor control comprises a step motor with motor control.

If greater efficiency is required then choose the highly efficient rotor.




EC-Motors

 
 
EC-motor_MC 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.
 

Energy label

 
 
energilabel
Via our calculation programs, it is possible to obtain an energy label which indicates the energy class of the air handling unit, provided the defined operating conditions are met.

Certificates

VEX100/VEX100CF/VEX200/VEX300

EXHAUSTO puts great emphasis on providing accurate data. So we use a third party to measure and check our data.

Eurovent certification

All data provided with the VEX100/VEX100CF/VEX200/VEX300 model has been measured.

The units have completed a major test programme in our development department and all of the capacity, efficiency and sound data is collected via testing and in real operating situations.

  I følge Eurovent test/-godkendelse iht. EN1886 og EN13053 opfylder EXHAUSTO VEX-aggregater følgende krav/klasser:

Unit’s stiffness:
D1(M)
  Air tightness class at -400 Pa : 
L1 (M)
  Air tightness class at +700 Pa:
L1 (M)
  Filter bypass leakage:
F9 (M)
  Insulation class:
T2 (M), U1≤1,0
  Thermal bridge class:
TB3 (M)

This means that a third party has checked that the data that our product calculation program produces complies with the real performance of the unit. Eurovent checks the data by selecting a unit at random and testing that unit at their own facility. If our stated data complies with the Eurovent's test results, we retain our certification. This guarantees the customer that our data is valid.


VDI6022 - German hygiene standard

EXHAUSTO has designed its units in accordance with the German hygiene standard VDI6022.

VDI6022 requirements
The unit's design must make cleaning easy. There may not be areas that cannot physically be cleaned and voids that are inaccessible must be sealed. Plates must be deburred to ensure edges are smooth and corners must be rounded to avoid the risk of injury when cleaning.

In addition,the condensation tray must decline to the outlet, so that water cannot remain in the unit. It is important that the condensation outlet is connected to the drainage system on a horizontal surface.

All non-metallic materials (e.g. seals, filters), are tested to show that they do not promote growth of mould spores and bacteria.


Because the unit is designed in accordance with VDI6022, it is both more hygienic and easier to clean.

Lukkespjæld firkantet studs Closing dampers can be ordered with or without spring-return for indoor or outdoor installation.

Outdoor installation

 
 
VEX240 med tag

The cabinet is insulated with 50 mm mineral wool and therefore well-suited for outdoor installation.

For outdoor installation, the air handling unit will be delivered with a roof which allows cables to be routed out from under the roof on both sides, as well as the rear of the air handling unit.

We recommend that air handling units which are installed outdoors, are secured further as described in the Outdoor-manual.
