Engineered Air's HRA Series is an energy recovery package specifically designed to reduce the high costs of conditioning ventilation air by recovering a significant portion of the thermal energy from the exhaust air.

Application

Air to air heat exchangers can be employed in any ventilation system to reduce energy consumption. Systems that see the greatest benefit are the ones that have high volumes of hot exhaust air that also need to preheat cold outside air.

With options including auxiliary heating, cooling, flexibility in unit configurations, control systems and protective coatings, HRA units can be effectively used in many situations. Learn More

Engineered Air's UV-C Lighting System, UV-Centurion, uses the latest UV-C lighting technology to control surface mold and microbial growth on your Air Handling Unit's (AHU) cooling coil, drain pan and filter bank. Placement of the UV-Centurion within the AHU is critical to properly irradiate the surface pathogens. Use of this total lighting system ensures the absence of surface growth, providing reduced maintenance costs and continued maximum operational efficiency of the air handling unit.

UV-Centurion direct and indirect irradiation design provides proper UV-C ray dispersion to cover the total controlled surface, killing most common molds, bacteria and viruses in under 60 seconds.

UV-Centurion triple zone coverage separates the rain pan/lower cooling coil module from the cooling coil / filter module to irradiate the areas where molds, viruses and bacteria are most likely to collect. This combination creates system lethal to pathogens. The drain pan module with reflector , directly and indirectly cover Engineered Air's Fast Pan / drain pan system keeping them clean and free flowing. The coil face / filter module continually bathe the face of the cooling coil killing any pathogens that may be deposited there, keeping them from multiplying and eventually clogging the coil. The downstream side of the filters is also bathed continually in UV-C, killing any growth on the leaving side before it can be released downstream.

Case Studies

• Grant Bone and Joint Revitalization Project - Columbus, Ohio - D5582 (TC-597)

  The Grant Bone and Joint Center building was originally a downtown Holiday Inn that over the years had been modified. As a former hotel the facility did not have any existing mechanical rooms and space on the roof was already limited with the existing chillers and air handling equipment.

  Grant Bone and Joint Revitalization Project

  

  ---

  Background:
  
  Grant Medical Center has been named one of "America's Best Hospitals" by U.S. News & World Report for excellence in orthopedics. Their all-inclusive specialty center features a comprehensive team of physicians committed to providing the most advanced treatment and therapy for everything from fractures to total joint replacement. Grant's experienced total joint replacement surgeons perform more than 1,500 cases a year.
  
  Grant Medical Center, a division of Ohio Health, decided to renovate their existing Bone and Joint Rehabilitation facility into a more modern facility with expanded service operating rooms for replacement of joints, bones, and additional orthopedic surgical needs.
  
  The Grant Bone and Joint Center building was originally a downtown Holiday Inn that over the years had been modified. As a former hotel the facility did not have any existing mechanical rooms and space on the roof was already limited with the existing chillers and air handling equipment. The downtown location of this building required any additional units to be roof mounted.
  
  The Application:
  
  The new operating rooms required temperatures to be maintain at 60º F (15.6º C) with a 50% constant relative humidity. These conditions were critical because many of the surgeries use unique sutures and glues that are dependent on precise levels of humidity to properly adhere.
  
  This, in combination with the surgical garbs worn by the surgical teams also required a lower temperature in the space with a consistent humidity. These conditions from the surgeons played a large role in this design of the new surgical suites.
  
  The Challenge:
  
  The existing chilled water system did not have enough capacity, or lower water temperature needed to meet the operating rooms air temperature requirements. There was also not enough roof space available to add a new low temperature chiller with an air handler.
  
  The cost of the chiller system was found to be more expensive than a packaged DX system. Another alternative proposed was to use a desiccant dehumidification unit but this would have also been cost prohibitive.
  
  In addition the consultant specified that when the surgery suites were not being used, the air volume had to be cut in half during “unoccupied mode/non surgery time”. This presented a major hurdle for a low temperature mechanical cooling application to overcome.
  
  The Solution:
  
  Working with Engineered Air’s Special Pricing Department, Columbus Sales proposed a dual cool unit design with an Engineered Air model FWA-186/O/MV/UVC. The equipment design was able to satisfy the surgeons comfort requirements. When the dual cool unit operates at 100% air volume during “Surgery Mode” it provides a 45°F/45°F (7.2°C/7.2°C) leaving air temperature utilizing both the first and second DX coils.
  
  The equipment also includes optional condenser reheat coil supplying 5°F (9°C) reheat to the dehumidified air temperature as needed. To provide additional zone temperature control the consultant had reheat boxes installed for each surgical suite.
  
  When the suites are in the “Non Surgery” mode the airflow is reduced to 50%, and the second DX system switches off only operating the first mechanical DX coil with a 55°F (12.7°C) leaving air temperature. Truly providing two operating systems in one.
  
  Summary:
  
  From this project we have received other multiple requests for this type of system. By including an ultra violet light “UV Centurion” system, it has made this a complete package for us to market. It is becoming more of a trend for surgery centers to be built in smaller or existing buildings where owners are unable to put in a low temperature chiller system. Since this project we have had another similar design with the consultant that is currently going out for pre-purchase.

The SI Series Oxidizer Units are self-contained air purification products designed to reduce high concentrations of odor & VOCs. They are a very economical solution, using minimal power consumption & requiring no additional chemicals or high priced media for operation and have extremely low maintenance.

The Oxidizer process is simple. High static voltage ionizes oxygen and then using basic principles of organic chemistry it naturally breaks down (oxidizes) gaseous compounds, leaving CO₂, H₂O and O₂ as the primary end products.

For maximum results, the Oxidizer units should be connected to the suction side of any ducted system to maximize contact time between the oxidant and odorous gases.

The Oxidizer units are easily adaptable to the A-TAC¹ system to create an automated air purification system, continually balancing oxidant levels with load levels for the air.

The Oxidizer will treat air problems in spaces where there are no existing air ducts² or can be used to inject ozone into ducted air systems.

¹ A-TAC is a series of IAQ sensors for air sampling on equipment regulation
² recommended use with A-TAC system if used in occupied space.

Oxidation Process

Oxidation technology can be effectively employed to break down odorous gases formed in wastewater facilities or any industrial site that causes problems for those living or working nearby. The oxidation process allows a form of oxygen (ozone) to combine with odorous molecules to break down the chemical structure and reform the atoms into simple compounds. Ozone is found naturally in the outdoors. Ozone is created by ultra violet rays from the sun or by high voltage electrical discharge during lightning storms. EngA’s Oxidizer 2000 copies nature by using high voltage to create a concentrated ozone discharge.

The TRI MED® Patented Process

The Oxidizer 2000 produces concentrated ozone within high voltage modules. A powerful fan draws the ozone from the modules combining them with the odorous gas molecules. The mixture of ozone and odorous gases is discharged into a specially designed reaction chamber. Chemical reactions take place that result in a deodorized mixture that is discharged to atmosphere. This patented process is completed with minimal operating cost, no hazardous waste to dispose of and no costly consumables to replace.
