Run around coil system for efficient heat recovery

The TROX run around coil system Hygienic, safe, efficient Run around coil systems (RAC) are regenerative heat recovery systems in which the airflows are completely separated from one another. As a result, they are suitable for applications in which no leakages between the supply and extract air are desired or permitted for hygienic reasons: for example in hospitals as well as in the food and pharmaceutical industries. They are also used if supply and extract air units are set up separately from one another due to the layout situation. A run around coil system consists of at least one heat exchanger...

The advantages at a glance Reliable data by certified design software The X-CUBE Configurator sales tool has been certified by the Association of Air Handling Unit Manufacturers for configuration of RAC systems as well. The calculation software has been specially developed in-house at TROX. Planners and system owners will receive precise and reliable figures for their planning within a very short time. High energy efficiency The TROX X-CUBE and TROX hydraulic unit have been consistently designed for energy efficiency. Low life-cycle costs are made possible by the design principle, insulation,...

The perfect overall system Optimum flow rate relationship The TROX hydraulic unit continuously balances the exchanger operating fluid flow rate with the air flow rate, and adapts them optimally. This guarantees high energy efficiency in all operating statuses. High operational reliability Pressure monitors with two switching points, a membrane expansion vessel and an 8 bar safety valve in the TROX hydraulic unit ensure high operational reliability. State-of-the-art technology ■ igh-pressure H multistage centrifugal pumps with IE4 motors ■ igh-quality stainless steel press-fit system H up to nominal...

Optional cold and heat feed A RAC system creates a closed hydraulic circuit, which means it is possible to feed additional heating or cooling capacity into the system. This option makes the air handling unit more compact, and eliminates the air-side pressure loss from cooling coils or heating coils. Depending on the building‘s requirement, the feed capacity can be controlled by various hydraulic circuits. Flexible feed control ■ hrottle T circuit E.g. for systems with condensing boilers or district heating connection Throttle circuit circuit For a variable flow rate in the consumer circuit and...

90% Dehumidification recovery 100% By using dehumidification recovery (referred to as: DHR), it is possible to reduce mechanical cooling for dehumidification of the outside air, e.g. for laboratories, clean rooms and the like. At the same time, this arrangement means there is no need for subsequent heating using conventional heating technology. A cooling coil (PCW) in the supply air unit dehumidifies the warm, moist outside air. The downstream heat exchanger integrated in the RAC system provides subsequent heating of the Nutzereingaben: dehumidified air to bring it to nominal temperature. The...
