Trane offers a complete line of self-contained systems. capacity ranges from 3 to 110 Tons in varied configurations for air-cooled, water-cooled and remote air-cooled requirements. self-contained systems designed specifically for renovation as well asAll of our products are designed to provide years of reliable, efficient, and quiet operation. Depending on the unit, our microprocessor controls offer direct or sensor interface, and always provide maximum operating efficiency. Several of our self-contained systems can be interfaced with building automation systems and several qualify for energy rebates, lowering the total cost of ownership.There are several different ways that water is used in air conditioning. The most common use is in cooling towers. A cooling tower can be any size, from really gigantic down to the size of an automobile. In a cooling tower, air blows over water to create evaporative cooling, and this cooler water is used in the heat exchanger of, say, an air conditioner.

A more direct form of evaporative cooling is often found in greenhouses, farmers' markets and chicken houses. In these kinds of systems, water flows over a mesh, and a fan blows air through the wet mesh into the building. Humid, cooler air is the result.

Water-Cooled Water Chilling and Heat Pump Water-Heating Packages. A factory-made and prefabricated assembly (not necessarily shipped as one package) of one (1) or more compressors, condensers and evaporators, with interconnections and accessories including controls, designed for the purpose of cooling or heating water.

It is a machine specifically designed to make use of a vapor compression refrigeration cycle to transfer heat from a cold water fluid circulating system to a warm water fluid circulating system.A unit that is not specifically listed in a publicly available sales brochure, magazine advertisement, website posting or Catalog / Selection Rating Application that is a single instance product which contains components or additions that change the performance such that ratings can no longer be obtained by utilizing the Participant’s Catalog / Selection Rating Application. Custom Units shall not be certified and shall not be listed in the AHRI Directory of Certified Product Performance.A unit that is produced and provided to a customer, for the purpose of gathering data on potential new products. These units are intended to transition into regular production should the field trial be successful. Field Trial Units are subject to the requirements of Custom Units. Field Trial Units shall not be certified and shall not be listed in the AHRI Directory of Certified Product Performance.

A new product is one that falls under the Program scope that is available to be marketed, but is not available for standard production and is not listed in the AHRI Directory of Certified Product Performance. Within nine (9) months after AHRI has received notification of New Product Introduction Unit, the Participant shall add the New Product Introduction Units to the Directory in accordance with Section 9.2 or else be in violation of AHRI’s Certify-All Policy.A modular chiller is a unit that is made up of multiple chillers that can function individually or as a single unit. Modular chillers shall be certified, provided that the chiller is rated and listed in the AHRI certification directory as a complete unit with a specific combination of modules and with a total capacity that is within the scope of the program. In this case, the complete Modular Chiller consisting of multiple modules must be certified as a single complete unit as part of the certification program.
