2 Knocks Down the Barriers to Cost-Efficient Comfort. The "new" Core with Ultra-thin 25 µm film has Achieved the Best Performance ever. Fresh air makes the difference For creating and maintaining indoor environments that are comfortable, healthy, and cost-efficient an air conditioning system alone is often not enough. Indoor air can grow stale with time, becoming polluted with formaldehyde, pollen, cigarette smoke, dust, and carbon dioxide. This is where the line of ventilators comes to the rescue, simultaneously expelling stale air and pumping in the vital fresh air needed to maintain optimum health and comfort. What s more, sensible and latent heat are both fully recovered, saving energy and reducing the overall operating costs of the system. Even more reasons to choose Improved sound attenuation makes Lossany units quiet enough even for places where very low noise levels are required such as meeting rooms. A free-cooling function is also available to help reduce costs and increase. The integrated system design makes installation and system management easy, and a wide range of models are available to meet the needs of any building type. A new "Ceiling-concealed" model has been launched for business use. It combines a "Hyper Core" to dramatically increase moisture permeability and gas shielding, and offers greatly improved heat exchanging to achieve the highest performance ever for a unit. Functions include "Multi-ventilation Mode," allowing the balance between air supply and air exhaust to be varied dynamically, and an external heater control circuit to cope with use in cold climates. The unit is able to handle a wide range of ventilation requirements, and is now even simpler to use.

This provides moisture permeability and air barrier properties, but the two-layer construction makes a certain thickness unavoidable. Supply airflow Non-porous ultra-thin film material: 25 Consists of a specially processed structure based on a single-layer non-porous ultra-thin film material. Moisture exchange (water vapor transmission) is promoted by the special ultra-thin film, which increases the affinity for moisture. (The thinner the film, the higher the permeability.) The non-porous ultra-thin film material acts as a barrier against air leakage.

Outdoor air though is rarely, if ever, the same temperature as that maintained by the building, s air conditioning system. In the summer, it is too hot. In the winter, it is too cold. This puts added stress on the air conditioner to compensate for the intake of the hot or cold air adding to the expense of operating the system. all but eliminates this problem with original energy-recovery technology that uses the heat of the stale indoor air to be expelled in order to either heat or cool the incoming fresh air to a temperature much closer to the existing indoor air. This process reduces the load on the air conditioning system without cutting off the supply of vitally necessary fresh air. Core Construction & Principle Stale air exhaust (dirty indoor-air) Outdoors Fresh air exhaust (fresh heating/cooling air) Indoors The basic principle The remarkable technology that permits the intake of fresh air with minimal loss to indoor temperature is know as the Lossany Core. The cross-flow, plate-fin structure of the energy-recovery unit along with a specially processed diaphragm keep supply and exhaust air separate, ensuring that only fresh air is introduced to the indoor environment while also allowing for the efficient transfer of heat. The improvements Power air supply/exhaust Most widely-used pattern forming the basis for traditional ventilation design. This allows the most efficient ventilation while maintaining the air supply/exhaust balance. The optimum ventilation rate can be maintained by setting to Power air supply/exhaust mode with the air supply switch to "" (or "") and the air exhaust switch to "" (or "Extra high") on the main unit. For example in an office, the control switches can be set to "" to run in Power air supply/exhaust mode when a large number of employees are present, and then ideally switched to "" to run in Energy-saving ventilation mode late at night or on holidays when there are few people present. Power air supply In smaller offices or tenant buildings, there may be insufficient air supply to the main rooms or offices with overall ventilation to the zones on each floor, due to the excessive exhaust via extractor fans located in toilets or kitchen areas. Setting to Power air supply mode with the air supply switch on "" (or "") and the air exhaust switch on "" on the main unit allows efficient ventilation while making up for the insufficient air supply. Power air exhaust In locations such as smoking areas, dirty air must be exhausted swiftly. Setting to Power air exhaust mode with the air supply switch on "" and the air exhaust switch on "" (or "") on the main unit allows efficient extraction of cigarette smoke and odors. Maintaining the area at a negative air pressure also prevents dirty air from spreading to surrounding areas. The microscopically small pores of the diaphragm have been made even smaller, decreasing the rate at which water soluble gases such as ammonia and hydrogen pass through. Further, a new specially processed paper used to make the diaphragm has been developed with high moisture permeability characteristics that aid in the Stale air induction transference of moisture for improved energy exchange. Fresh air induction (dirty heating/cooling air) These developments further improve moisture permeability and (fresh air) effectiveness in shielding unwanted gases, resulting in a lower rate of gas transference and more highly efficient energy transfer. 3 4

6 A Breath of Freshness in Restaurants, Offices, and Schools Restaurants Offices Schools A restaurant can never be too clean and its air never too fresh The atmosphere of a restaurant is crucial to securing customers and making them happy enough to come back for more. Cleanliness is the key to an attractive atmosphere and restaurants devote significant effort to ensuring the premises are sanitary. Sanitation and cleanliness, however, are not enough. No matter how clean a restaurant may look, if there are bothersome odors lingering in the air, all those efforts go to waste and the restaurant's clean image is tarnished. For these reasons, we invite restaurant owners to leave the air to. s superior ventilation capabilities ensure that every breath is a breath of freshness keeping guests happy. also keeps owners happy with its remarkable heat recovery technology that supplies fresh outdoor air with minimal change to indoor temperature, saving on energy and expense. Fresh air improving the overall quality of working life Many office buildings today are heavily insulated air-tight structures with little or no natural ventilation. The unnatural environment created by air conditioners without added ventilation is a breeding ground for bacteria. Factor this in with the accumulation of pollutants and odors in the form of cigarette smoke, formaldehyde, pollen, dust, and carbon dioxide, and the necessity of ventilation becomes ever more apparent. In fact, poorly ventilated buildings can give rise to Sick Building Syndrome, a malady that is known to cause headaches, sore eyes, itching, and concentration loss. This results not only in discomfort at best and sickness at worst for the building's occupants, but also the reduced productivity of the workforce. Fresh air, effectively ventilated throughout the building, is therefore essential to the overall quality of working life. Creating the best possible environment for our children to succeed Children deserve all the help we can give for them to grow up healthy, happy, and prosperous. No matter how good a school's curriculum, no matter how positive and enthusiastic the teacher, a child who does not feel well will have a hard time learning. The constant flow of fresh air is nowhere as important as it is in our schools. In classrooms where large numbers of students are gathered for long periods of time, carbonic gases have the tendency to accumulate, decreasing the levels of oxygen that are vital for alertness and concentration. This is especially true during the winter months when windows tend to remain closed. ventilates fresh outdoor air into classrooms to replenish the supply of oxygen and expels not only carbon dioxide, but also other pollutants and odors that inevitably sully the air. If it s... If it s... If it s... Ventilators work to exhaust stale air and supply fresh, clean air free of the odors associated with cooking, cigarettes, and the people working and dining. Simultaneous forced-air supply and exhaust introduces fresh, outdoor air into the building, effectively ventilating even fully airtight structures. The continuous influx of fresh, outdoor air and the exhaust of stale, indoor air ensure that the indoor oxygen level is maintained at just the right balance for comfort and health. Change in room temperature is kept to a minimum during ventilation thanks to the heat-recovery function. Multiple split-type units operate independently of one another, simplifying system set up and ensuring a layout that optimally matches nearly any office design. Occupants have the luxury of breathing fresh air at all times even in highly air-tight buildings. The ventilators operate very quietly so those in the midst of enjoying their meals will not be bothered by any excess noise. operation can be interlocked with air-conditioning system operation. 's sound attenuation qualities prevent outside noise from penetrating into the room, helping to maintain a quiet environment for productive study. A large array of ventilators is available to match the layout of just about any restaurant. Heat that is commonly lost due to ventilation is collected and reused thanks to the Core, reducing air conditioners energy load and cutting operating costs. Heat-exchange technology prevents fluctuations in temperature for significant energy savings when either heating or cooling a room.
