how to service air handling unit

With the X-CUBE compact TROX has created a ready-to-operate and pre-configured air handling unit that combines the excellent features of the X-CUBE in the smallest of spaces. These units handle volume flow rates of 600 to 6,000 m³/h and offer a heat recovery efficiency of over 80 % (dry, to EN 308), hence they are the ideal solution for small and midrange applications. TROX offers nine different X-CUBE compact units with a choice of two different heat recovery systems..Top performance, small size Volume flow rates of 600 to 6,000 m³/h Powerful EC fans also for high external differential pressures High level of hygiene (conforms to VDI 6022) Heat recovery with heat wheel or counter flow plate heat exchanger Air filtration with TROX minipleat or NanoWave filters Ready-to-operate unit (plug and play) Operating side can be changed at a later stage Integral, bus compatible control technology Advantages at a glance Seamless integration into modern building management systems

The X-CUBE CROFCU is a compact ventilation unit that ensures and maintains the essential conditions for all classes of clean rooms. The secondary unit for use with centralised ventilation and air conditioning systems is typically installed in false ceilings.
new outside ac unit costIt dissipates high thermal loads and requires only a low fresh air volume flow.

outside ac unit does not come on Suitable for all clean room concepts Pumped chilled water cooling system with room temperature control Increased flexibility if several units are connected Energy-efficient plug fan with EC motor

Addition of fresh air from 50 m3/h to 2000 m3/h Monitoring of filters downstream Control of airlocks for people and material Contamination check by means of pressure zone control Space-saving due to smaller ducts Simple and quick commissioning due to plug and play With the TROX X-CUBE, an air handling unit with unlimited configuration options, TROX sets a new standard in the AHU market and defines considerably higher levels of quality, performance, flexibility, reliability, energy efficiency, and hygiene. Compelling all down the line. TROX now offers everything from a single source: air handling units and components – ideally complementary to each other.For even more energy efficiency and better quality with less coordination effort. For the ventilation of rooms and entire buildings, for filtering, heating, and cooling the air, for heat recovery as well as for humidification and dehumidification, and for volume flow rates of up to 86,000 m³/h

High-static design meets a wider range of applications than competitive packaged air handler lines.Ultra LOW LEAK Economizer accessory provides ventilation air and “free” cooling with built in Fault Detection and Diagnostic (FDD) capabilities.Cooling coils with mechanically bonded fins provide peak heat transfer.Hot water coil, steam coil, and electric heat accessories are available.Standard factory-installed thermo-static expansion valves (TXV) with removable power element on 40RUA units.Die-formed galvanized steel casings provide durability and structural integrity. Optional paint is available.Optional Staged Air volume (SAVt) system with 2-speed indoor fan VFD controller (07--30 models)FEATURES / BENEFITSEasy-to-install and economical 40RU units provide reliable service.The 40RU Series air-handling units are the best choice for packaged air handlers. Model 40RUA units have direct-expansion coils. 40RUS units are chilled water packaged air handling units. All models offer excellent fan performance, a unique combination of indoor air quality features, easy installation, and affordable prices.

Their versatility and state-of-the-art features will provide economical performance now and in the future.Indoor air quality featuresThe unique combination of features in the 40RU Series air handlers ensures that clean, fresh, conditioned air is delivered to the occupied space. Cooling coils prevent the build-up of humidity in the room, even during part-load conditions. Unit sizes of 10 tons and above feature dual-circuit face-split coils. Two-inch (51-mm) disposable filters remove dust and airborne particles from the occupied space. Thermal insulation contains an immobilized anti-microbial agent to inhibit the growth of bacteria and fungi. The anti-microbial agent is registered with the U.S. Environmental Protection Agency (EPA). Pitched drain pan can be adjusted for a right-hand or left-hand connection to provide positive drainage and prevent standing condensate.EconomyThe 40RU Series packaged air handlers have low initial costs, and they continue to save money by providing reduced installation expense and energy-efficient performance.

Quick installation is ensured by the multi-position design. Units can be installed in either the horizontal or vertical (upflow) configuration without modifications. All units have drain-pan connections on both sides, and pans can be pitched for right-hand or left hand operation with a simple adjustment. Fan motors and contactors are pre-wired and TXVs are factory-installed on 40RU models. High-efficiency, precision balanced fans minimize air turbulence, surging, and unbalanced operation, thereby cutting operating expenses. Economizer accessory precisely controls the blend of outdoor air and room air to achieve comfort levels. When the outside air is suitable, outside air dampers can fully open to provide “free” cooling. Economizer is an Ultra LOW LEAK design that includes return and outside air damper leakage that meets California Title 24 section 140.4 requirements. Controller meets California Title 24 Section 120.2 Fault Detection and Diagnostic (FDD) requirements.Rugged dependabilityDie-formed galvanized steel panels ensure structural integrity under all operating conditions.

Mechanically bonded coil fins provide improved heat transfer. Galvanized steel fan housings are securely mounted to a die-formed galvanized steel deck. Rugged pillow-block bearings (14 thru 30 size) are securely fastened to the solid steel fan shaft with split collets and clamp locking devices. Smaller unit sizes have spider-type bearings.Coil flexibilityModel 40RU air handling units have galvanized steel casings; inlet and outlet connections are on the same end. Chilled water coils have 1/2-in. (12.7mm) diameter copper tubes mechanically bonded to aluminum sine wave fins. All chilled water coils have non-ferrous headers. Direct expansion (DX) coils are designed for use with Puron® R-410A refrigerant and have copper tubes mechanically bonded to aluminum sine-wave fins. Direct-expansion coils include matched, factory-installed thermostatic expansion valves (TXVs) with matching distributor nozzles.Easier installation and serviceThe multi-position design and component layout allow for quick unit installation and operation.
