Lennox was founded in Marshalltown, Iowa (USA) by Dave Lennox. Their international headquarters are based in Dallas, Texas. Being a leading provider of climate control solutions Lennox' net sales rose above 3.7 billion $ in 2006. Lennox designs, manufactures and markets a broad range of products for the heating, ventilation, air conditioning and refrigeration markets. Lennox International employs approximately 16,000 employees throughout the world with 1,700 in Europe. Lennox Europe operates four factories in Europe.

Lennox is allocating 3% of its turnover on Research and Development in Europe. Together with the industry recognised R&D power of Lennox USA, Lennox wishes to be seen as the leading player in HVAC innovation. Every year Lennox applies for patents, and also works closely with their partner suppliers on common research programmes. All of Lennox' manufacturing centres of excellence are equipped with state of the art laboratories. This enables Lennox to test products in all conditions to reach the highest level of reliability possible. The laboratories are used with new product development and advanced research where new concepts are constantly tested.

Lennox provides a variety of air to air products, from small packaged equipment to the rooftop packages, the range is from 2 kW to 250 kW. Lennox packaged products have superior reliability and efficiency. Perfectly adapted to single floor buildings such as retail centres or factories, rooftop packages include air filtration, cooling capability, and different types of units in a single product. Lennox rooftop packages are the cutting edge of the market. Innovation applies to noise level, life cycle cost and indoor air quality making Lennox rooftop packages undisputedly top of the market. With the development of geothermal applications, most of these products are available with water cooled possibilities. To serve the market with a high level of fresh air, Lennox supplies the heat recovery rooftop packages. Close control units are an important part of the company portfolio, specifically designed for telecom and data centres.

With chiller from 8 to 750 kW and fan coil units or air handling units, Lennox can provide a full system optimized for hotel applications or office buildings. The chiller range includes cooling only or heat pump, either aircooled or watercooled. On top of a long list of options, Lennox offers the custom made units for even more flexibility. Chilled water cassette, concealed fan coil or pressure fan coils are examples of terminal units available. The water system solution from LENNOX constitutes an ecological alternative to systems VRV and VRF. The use of water to transfer energy from refrigeration or heating reduces the costs of installation and maintenance compared to direct expansion systems with a refrigeration circuit. The implementation of the Lennox system results in an economic installation. Additional options, in particular of user interface of the fan coils, complete the system and make it the ideal solution for small offices or modular buildings. Hydrolink offers a total flexibility to combine the fan coil units in order to fulfil the requirements of your application.

New design meets new requirements. Just as the theory of Moore’s law, the design of data centres & computer rooms moves us fast into a new era. The respect for the natural environment, green solutions and energy efficiency need to meet tomorrow's demand. High-tech environments require dedicated environmental control. Energy efficiency, flexibility and modularity are criteria of today’s equipment design. The complete range has been developed using the latest state of the art designing tools to reach a maximum functionality 24 hours a day, 365 days a year. Lennox can provide @DNOVA™ units which are designed for inside or outside installation of telecom shelters in the range of 2.5 kW to 25 kW. The series of INNOV@™ (6 kW to 249 kW) Close Control Air Conditioning units are designed to guarantee and respect all environment protection parameters; they represent the perfect answer to all technical requirements of different technological plant concepts (computer rooms, datacenters, control rooms, EDP rooms, textile industry, metrological rooms, etc ...).

Monitoring and building management systems are the last parts of the system puzzle. It creates the link between the customer and the system. Lennox designs and provides building management systems adapted to all products and sites. Lennox can provide two solutions; ADALINK™ for BMS “light” system up to 32 units and LennoxVision™ for connection to all the Lennox units and external components up to 750. ADALINK™ is the LENNOX solution for HVAC installation monitoring. It can control up to 32 units on the same site. It can be connected to different units of the Lennox range, rooftops and chillers. Very easy to install, it can be used on any computer through Internet Explorer locally and remotely via an internal modem (RTC or GPRS).The LennoxVison™ software gives you access to different pages in order to fully manage the different units on the site; unit page, service, alarm, curves and scheduling pages. The system includes remote connection via modem (options), communication with other BMS, management of alert messages by SMS or Email and lighting management.
