Air Handling Unit is the "heart" of HVAC system!!!


AIR HANDLING UNITs


An Air Handler is a device used to regulate and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. An air handler is usually a large metal box containing a blower, heating or cooling elements, filter racks or chambers, sound attenuators, and dampers. Air handlers usually connect to a ductwork ventilation system that distributes the conditioned air through the building and returns it to the AHU.
FEATURES:
  • The units are assembled from a wide range of standard sections
  • Hard fastness between panels and frame to ensure good air tightness.
  • The spiroduct can be connected directly to the sections for easy installation.
  • The AHU have very good acoustic and thermal insulation
  • The AHU can be delivered both as galvanised or stainless steel
  • The units are delivered with wave breakers and water traps
  • The fan and motor are mounted on vibration dampers with flexible connections

AHU Cleaning Process

Following is our defined procedure we undertake while cleaning AHU units.
  • We switch off any external installed filteration system or UV lamps. Before turning off the unit, we take various readings of AHU system.
  • We then do a thorough internal inspection, ie. containmined AHU floor, moulds, bacteria, valves etc. If minor dust or mould is found then we disinfect it immediately to prevent cross containmination.
  • Internal lights are checked for problems.
  • All electricals are checked for faults.
  • Fan Belts, Condensor Coils, Drain Trays are checked for any  dirt's, moulds, bacteria build up and any maintenance required that would is checked.
  • The above is necessary to prepare a quote for a complete thorough cleaning.
  • Approval of Work: If you accept our quotation, we then prepare a detailed plan, assign work to various team and schedule your job at a date convenient to you.
  • Cleaning Process: On the Scheduled date, we ensure that staff is uniformed, with proper clothing, protective eye gear for protection from possible eye strain.
  • We start by applying de-greasing chemical to the entire inner and outer walls of AHU.
  •  Then we do a pressure wash to remove the grease and black particulate.
  •  Then the inner and outer walls are sprayed and washed with standard dis-infectant. Coils, Drip tray are cleaned and dis-infected.
  • Floor in the AHU room is vacummed to remove any water spillage.
  • All electrial components are switched on again and unit is re-commissioned.
