The EASYAIR® air handling units are equippedwith a highly effi cient energy recovery system. The airhandling units guarantee an effi ciency of 80 – 90 % inaccordance with the European Guideline DIN EN 308.

The components are specifi cally designed to optimise effi ci-ency. The aerodynamic effi cient arrangement of the compo-nents combined with reduced pressure losses on the air sideand the fans with modern EC drive technology, enable an extremely energy saving operation throughout the year.

By using these components in addition to the high quality casing of the unit it is possible to reduce acoustic emissions signifi cantly.

The intelligent control system of the EASYAIR® is easy tohandle. The control unit manages the energy-optimisedoperation of all components. The complete unit is delivered as a plug-in system, no wiring installation work, just conn-

cet for power (and often cooling and heating medium) and EASYAIR® can be started immediately.

EASYAIR® can be chosen within air volume ranges from 650 to 13.000 m³/h (different sizes).

eneV 2009 (energy saving regulation)EASYAIR® air handling units are manufactured and designed in accordance with the European Guideline EnEV 2009. It must also be highlighted that, as a result of the high efficiency of the heat recovery (80 – 90 %), achieved from the energy efficient motor technology for the fans and due to the intelligent control of all components, all EASYAIR® air handling units are far superior to the current requirements as laid down in EnEV 2009.

VDi 6022 (hygienic requirements)All EASYAIR® air handling units are manufactured and designed according to the European Guideline VDI 6022. The casings of all EASYAIR® air handling units are powder-coated on both sides. Other components are made from galvanized steel. All EASYAIR® air handling units provide easy access for any possible service and maintenance works in accordance with VDI 6022.

heat recoveryA choice can be made between rotary (thermal wheel) or plate heat exchanger-units. Rotary heat exchangers are preferred when re-circulating air operation is possible. To prevent cross-flow contamination between supply and exhaust air, the use of plate heat exchangers is recommended.

i ro- = with Rotary heat exchangeri pL- = with Plate heat exchanger

i RO-04-r = Service side in supply air direction righti RO-04-L = Service side in supply air direction left

splitted design / outdoor designFor unit size 04, there is the possibility to order EASYAIR® in a split design. Thus, the air handling unit can be installed very easily, even e.g. when the access openings (building doors) are limited in width or height. Please refer to the dimension table on pages 4/5 and 6/7.

All EASYAIR® units can be ordered for outdoor installation as weatherproof units. Weatherproof units are only available as one-part units and have a weatherproof roof with drip tray. As an option, weatherproof units are available with an intake and extract hood.

i RO-04-R-X = Casing in non-split designi RO-04-R-T = Casing in split designi RO-04-R-W = Casing for outdoor installationi RO-04-R-h = Casing for outdoor installation with an intake and extract hood

Filter classesAs standard, the EASYAIR® is supplied with highly efficient air filters. In the supply air there is a F7 and in the exhaust air there is a F5 filter installed. The quality of the filters are according to VDI 6022.

equipment standsAll the EASYAIR® air units can be ordered with practical, individual stands which allow the units to be adjusted to each and every situation. The EASYAIR® unit can therefore be correctly assembled in most situations, even when the sub-surface is not ideal.

i RO- = with rotary, heat-exchanger without a standi RC- = with rotary, heat-exchanger with a standi PL- = with a plate, heat-exchanger without a standi PC- = with a plate, heat-exchanger with a stand

unit sizesBoth types of heat recovery units areavailable in various sizes. For each size as well as their optimized air volumes, please refer to pages 4 and 5.

i RO-04 = Size 04, for air volumes between 2.000 and 5.100 m³/h. Sample for selection is done by choosing an EASYAIR®

with rotary heat-exchanger (RO-), size 04 (RO-04).

service sideOf course, it can be chosen where the service side of the EASYAIR® should be located so that easy access is ensured for maintenance and service. The location of the service side is always based on the direction of the supply air. The service side in the right hand, supply air direction conforms to the illustration shown on pages 4 and 5 (f. e.).

DampersThe EASYAIR® is supplied with internal, air tight dampers (tightness class 2). One damper at the air inlet for outside air and one damper at the air outlet for extract air. Therefore, additional dampers are not required to be installed in the supply and/or extract air ducts for the majority of applications. The internal dampers are supplied with actuators.

silencer module (sound absorber)The noise emmissions from the EASYAIR®-Equipment, which are already designed to be minimal, can be further reduced by ordering an optional silencer module. Various silencing options are available and our two silencing units, with differential insulation levels and measurements can comply with most requirements.

evaporator / condensermodule (option)EASYAIR® -units with dimensions from -02 can be operated with a rever-sible cooling and/or heating machine which enables the heating and cooling processes to function without additional hot and/or cold water supplies. The chosen system comprises of an add-on, complete evaporator, expansion valve and control unit. These components are pre-installed and are integrated in the high quality unit housing of the EASYAIR® Add-on. A inverter-controlling unit from LG (Multi V) is installed as an external operating unit. This unit justifies its inclusion due to the high COP/EER-Values and is operated with the highly-efficient cooling element R410A.

controlThe EASYAIR® air handling units have standard integrated controller. All the internal components of the units are prewired and ready for use. An extract air temperature sensor in combination with a heating and /or cooling coil guarantees a constant supply air temperature. The majority of the energy efficient, control functions are integrated in the software and are easily extended by using additional options.

The available options are as follows:

i -ra = Room sensori -DK = Constant pressure controli -VK = Constant air volume controli - aQ = AL-KO air quality control in the extract ducti -rc = Remote control with 10 m cablei -BL = Bus module LONi -Bm = Bus module Modbusi -BB = Bus module Bacnet/Etherneti -cX = Without control

note: The measurement values (data points) and communication commands are permanently configured and are independent of the Bus module and cannot be changed.

Without controlAll field devices are wired for easy connection to an on-site controller, on a terminal strip. Therefore, there is no separat unit or on-site wiring required. Furthermore, a main switch for all-phase switching is installed on the unit. The power fuse is not included in the design and must be supplied on site.

Unit design and options

For EASYAIR® units with rotary heat-exchangers, the connections of the drive motor are supplied through the terminal strip. The unit has no integrated rotor control. Only a rotor drive with integrated speed set point input is provided. The operation is additionally monitored using a potential-free (closing) contact fed through the terminal strip.

The AL-KO air-quality controller AIRQUAlItIZeR® monitors the

quality of the extract air. If this sensor detects odours or emissions in the extract air (VOC = Volatile Organic Compounds), the quantity of air is increased and, within a short period of time, good quality air is guaranteed in the room again. If there are e.g. only a few people in the room, the AIRQUAlItIZeR® can reduce the air volume (partial load operation) and you are able to reduce the operating costs. By using this intelligent air flow management, only the required air flow is conveyed.
