4 KOMFOVENT OMEKT ir Handling Units Komfovent ir Handling units are made to create healthy indoor climate and ensure efficient energy saving. Products are designed and produced in conformance with high quality and performance requirements. ll components and parts of the units are accurately selected and assembled to achieve the best results in operation. Reliability of the products is based on the deep attention to the details. Your family health protection Units efficiently clean the air from the particulates, allergens, dust and maintain healthy indoor climate. Energy Efficient Silent operation. Reduces expenses for heating, saves electric energy. ue to the efficient heat exchangers which recover up to 9% of exhaust air to warm up the supplied air, the heating expences are reduced up to 0%. Highly efficiencient E (electronically commutated) motors use 50% less energy than (alternating current) motors with voltage control. The special control system designed by our qualified engineers contributes to saving energy. Reliable and durable ouble quality control system. ir handling units efficiency is measured in a new modern laboratory. Units are tested in the independent laboratories in Switzerland and Germany. ouble anticorrosive units casing protection. Wide range of air handling units We are offering an extremely wide range of air handling units in order to fulfil our customers needs. User friendly control system Modern and attractive control panels enable a customer to select the desirable functions, set and change parameters as well as observe the ventilation processes on L screen. KOMFOVENT OMEKT ir Handling Units are intended for residential premise ventilation within 0m to 50m. Two functions in one unit: 1. Ventilates premise: ensures balanced ventilation with heat recovery supplying fresh air and extracting the used one.. Possibility to connect a kitchen hood or any other extraction device. Special design of the units no need to specify the inspection side it is both right and left hand in one. Ventilation units with integrated automatic control are fully prepared for installation: just PLUG & PLY. wide range and extremely compact size of the units allow the customer to mount them not only in the new premise but also in the renovated ones. U MLV reserves the right to introduce changes of parameters and sizes in the process of improvement of the air handling units.

7 Vertical unit OMEKT REGO 00 Unit is specially designed to be integrated into the kitchen furniture over the cooker. Its extremely compact size gives us a perfect possibility of simple mounting in a new flat, renovated premise, etc. Unit is applicable to ventilate the premise up to 10m. Ventilation unit is fully prepared for exploitation. Integrated automatic control with the wall mounted panel which is handy and simple in use ensures the most economic unit functioning and necessary control. Unit REGO 00 performs two functions: 1. ventilates premise: ensures balanced ventilation with heat recovery supplying fresh air and extracting the used one,. extracts the used air through kitchen hood: during cooking a user switches on the hood and the air is extracted through the hood by the unit. Kitchen hood has a specially designed damper inside. The air flow through the hood is adjusted with it. NOTE: There is no danger of rotary wheel greasing because air flows are not mixing in the unit when you are cooking! WHY? ecause when you are cooking you switch on a cooker hood and it opens an internal by-pass damper by this action. Used air from cooking and fumes is extracted by exhaust fan and directed to the by-pass, without getting into rotor. Extract air fan can be easily taken out for cleaning when it is needed. Operation principle: when kitchen hood is switched ON Operation principle: when kitchen hood is switched OFF Extract through kitchen hood Extracted air from premise Supplied air Outdoor air Exhausted air outside Extracted air from premise Supplied air Outdoor air Exhausted air outside U MLV reserves the right to introduce changes of parameters and sizes in the process of improvement of the air handling units. 5

Override = ignore) function is intended for the remote unit s control with an external accessory device. fter this function is activated the current unit s mode becomes omissible and the unit starts working according to the newly set parameters. pplications of the OVR functions: Maintenance of O quantity in a room by adding an additional O sensor (with relay), the main user-set ventilation rate at higher O will be switched to the maximum intensity until the room is ventilated, and then again will return to the user-defined intensity. Maintaining relative humidity in the room after contacting the external relative humidity sensor (with relay), automatically switching to maximum or different set ventilation intensity the humidity level desired by the user will be maintained. Ventilation on demand when the motion sensor is connected to the control contacts, ventilation will be adjusted according to the demand, i.e. if people are indoors, ventilation will be carried out according to the set OVR intensity and if there s nobody in the room - the unit will operate according to the main user intensity, for example, the minimum. Ventilation with additional air extraction connection of an additional extracting device, for example, a kitchen hood or other extraction device without a separate fan, is intended, thus the air extraction is carried out by the unit itself. fter the activation of the function the supply and exhaust air fans start operating at the maximum intensity. Negative pressure compensation intended for the systems where air extraction can be carried out in a separate air extraction fan. Thus, for the compensation of negative pressure in a room, the OVR function can be activated by the separate control contacts. fter the activation of the function the exhaust air fans start operating at the maximum intensity and the exhaust air fan goes off. 6 U MLV reserves the right to introduce changes of parameters and sizes in the process of improvement of the air handling units.
