Ductless rooftop air conditioners LM PRO ORION TOP are an advanced line of outdoor supply and exhaust recuperative units designed for installation on the roofs of buildings.
Rooftop ductless air conditioners are an innovative product on the market ventilation equipment. To create this series, modern technologies, the latest design solutions and many years of experience were used, which made it possible to obtain a whole range of advantages.

The vortex adjustable air distributor, depending on the operating mode, can change the shape of the air stream.

Heating mode

The supply air temperature is higher than the room air temperature. Consequently, the air, having been distributed, rises. How more difference temperatures supply air and air in the room, the less twisted it should be to ensure optimal range and air supply directly to work area

Isothermal mode

The supply air temperature is equal to the room air temperature.

Cooling mode

The supply air temperature is lower than the room air temperature. The air is distributed horizontally parallel to the ceiling. Having been distributed, the air falls down into the work area, without creating the feeling of drafts.

Designed for use on large objects with large open spaces and high ceilings - industrial premises, warehouses, shopping centers, stadiums, etc. The units are installed in the roof of the building and prepare supply air and distribute it directly to the work area, as well as remove exhaust air with the possibility of partial or complete recirculation.

• Dual fans with a “free” wheel provide minimal power consumption and noise, as well as 50% redundancy due to the parallel independent operation of two fans.
• The built-in plate recuperator ensures heat recovery from the exhaust air.
• The adjustable swirl diffuser allows for optimal air flow structure depending on the supply air temperature and the required design solution.
• Heated air valves (optional) allow the unit to be started and operated at outdoor temperatures down to -40 oC (without this option up to -25 oC).

Roof-mounted ductless air conditioners are an innovative product on the ventilation equipment market. To create this series we used modern technologies, the latest design solutions and many years of experience, which made it possible to obtain a whole range of advantages.

Advantages of using INTAKT PRO air conditioners:

• dual EC fans ensure low noise and energy consumption;
• the built-in plate recuperator ensures heat recovery from the exhaust air and saves the heater’s thermal energy;
• to increase the energy efficiency of the installation, it is equipped with a mixing chamber, which utilizes both sensible and latent heat;
• no need for organization ventilation chamber, which allows you to significantly increase usable space building;
• there is no need to design, purchase and install: air ducts, ventilation grilles and diffusers, insulating materials, consumables installation materials, which leads to a reduction in capital costs for engineering equipment building;
• It is enough to connect to this system: electrical wires, heating lines and pipelines of the refrigeration system;
• The issue of the room air conditioning system can be resolved by simply dividing the area of ​​the room by the processed area of ​​the selected INTAKT PRO standard size;
• The vortex adjustable air distributor, depending on the operating mode, can change the shape of the air stream. Unique design allows air to be supplied to the working area of ​​the room at any time of the year without the risk of reducing the comfortable stay of people in the room.

Air jet formation modes

Heating mode. The supply air temperature is higher than the room air temperature. Consequently, the air, being distributed, rises. The greater the temperature difference between the supply air and the room air, the less swirling it should be to ensure optimal range and air supply directly to the work area.

Isothermal mode. The supply air temperature is equal to the room air temperature.

Cooling mode. The supply air temperature is lower than the room air temperature. The air is distributed horizontally parallel to the ceiling. Having been distributed, the air falls down into the work area, without creating the feeling of drafts.

When placing INTAKT PRO units, it is necessary to exclude the possibility of exhaust air from one unit getting into the intake of another unit. To do this, it is necessary to direct the exhaust grilles of the units towards each other. The exhaust grille should not be blocked by anything to ensure effective removal of air from the room. To service the heat exchangers, it is necessary to leave free space on the side of the removable panels; the panels are completely removable and do not have hinges, so a minimum of space is required for maintenance. The supply air stream must be supplied to the working area completely unhindered, therefore, when locating the units, it is necessary to ensure that there are no obstacles in the direct air distribution zone. The units are supported on the mounting frame by their own weight. Silicone is required for sealing polyurethane foam or similar substance. The filter insert on the exhaust part is replaced through the external module (pulled up).

BOX rooftop air conditioners - features and benefits

All BOX rooftop air conditioners consist of two key elements - external and internal units. The external unit is mounted on the roof (supplied with a roof plinth selected for the roof type) and is frame structure from reliable and strong materials. The casing is based on galvanized steel panels filled with polyurethane foam. Panels provide good insulation heat and reduce its losses to the minimum possible number.

External units are also equipped with convenient service panels that are sealed and can be dismantled for repair and maintenance in a minimum amount of time. In external unit usually includes the following elements:

• Air intake, exhaust, recirculation valves;
• Fans;
• Filters of varying degrees of purification;
• Heat utilizers.

The indoor unit works with air coming directly from the room. He gives it and takes it away, ensuring a constant and high-quality exchange. The indoor unit contains a heat exchanger, an air distributor, a counter element for the air duct or an air distribution grille. Since the heat exchanger is mounted inside this unit, you can not be afraid of freezing in winter and operate the air conditioner even in severe frosts. In addition, if desired, the air conditioner can be equipped with a separate air cooler through the internal unit.
