A new BacNet DDC system replaced the existing pneumatic system. A new water cooled rotary screw chiller was also installed to handle the increased cooling load. PM/ME – Havighust Hall is a 71,277 sf, three story dormitory building built in 1983. The existing two-pipe fan coil system was replaced with new DDC units. New isolation valves and drain valves were provided at the bottom of the combination chilled / heating hot water risers. Existing multizone air handling units AHU-1, 2 & 3 were replaced with VAV units and VAV w/reheat boxes were provided for each zone. A total mechanical room upgrade was also designed including: steam pressure reducing stations, heat exchangers, pumps, valves, condensate sets, insulation, ventilation, etc. $1,580,000. PM/ME – Project included replacement of two existing air handling units serving the upper three floors of Upham Hall. A demand controlled ventilation (CO2) system was provided to minimize energy used to condition outdoor air. The new air handling system was variable air volume.

PM/ME – Renovation of the existing 37,750 sf single-story building located at 955 Eastwind Drive in Westerville, Ohio. The interior of the building was renovated to support medical office and support space. In addition, the facility included an imaging suite and an ambulatory surgery center. The project required an analysis of the existing mechanical systems and electrical service capacity. Separate from the main building systems, the ASC component required a stand-alone HVAC system and generator backup. Word not found in the Dictionary and Encyclopedia.

Let me give a brief explanation.

The principal of a cleanroom is to dilute particulate concentrations by introducing cleaned air (in some areas, first pass air is used to create a clean zone within a cleanroom), minimise particulates production in the area exclude all foreign sources of particulate. Principal of a clean room air handling unit versus and air-conditioning evaporator/air handling unit: Clean room air handling in commercial air handling unit/evaporator This is by no means an exhaustive list but there are two items you can gain from the above table. Firstly the only item that clean room air handling units can generic evaporators/commercial air handling units have in common is that they address temperature. Secondly the main purpose of both systems is vastly different, one is to facilitate production the other is to facilitate comfort. In mechanical services, it’s like the difference between passenger car and an aeroplane. Both are used to condition the air, but one is expected to be used for work (production) the other is used to make you feel comfortable.

As you would imagine, if you tried to drive a car at the ocean to get New Zealand, you may have some mechanical failures, simply because your car is not being used for its intended purpose. This is the same as trying to use standard air handling units or evaporators in a cleanroom. So what is the solution? The solution is easy: to have a mechanical services system designed and constructed to the specific specification of your cleanroom. One of the frequently asked questions we hear is: I only want entry-level cleanroom, I want to use my existing air conditioning for the cleanroom. Sure, as long as it specifically addresses the requirements of your specification for your cleanroom. If somehow your air conditioning system can be modified to reach your cleanroom specification (even the really simple ones) you’ll find that no manufacturer is prepared to warrant modifications. This is not unjust, just like trying to drive to New Zealand, comfort air conditioning is never designed to meet the requirements of a specific cleanroom.

But here comes the caveat, depending on what type of air conditioning your facility currently uses, the size of your current air conditioning and how clean your current air conditioning system is. There may be some opportunities for reuse existing within the new cleanroom design; things such as access chilled water and ductwork may be incorporated minimising capital and labour costs. Yes, it’s true we design cleanrooms and we also construct them. The benefit we find to this is, it can be constructed to our exacting specification more readily than if we let it out to tender.One of the items we design and construct is our own cleanroom air handling units. Depending on project timelines, size of jobs or access or lifting equipment, it may be necessary for us to design and construct a handling unit, here in our workshop or on-site. If you need and a cleanroom air handling unit for a new facility, facility upgrade, refit or modification, contact us! New cleanroom facility air handling units.

We would be happy to supply air handling units for your new facility, as I previously mentioned above, we understand the issues with air handling units in cleanroom applications, and we understand exacting specifications, the first thing we need for a new facility handling unit is a specification. If you require a cleanroom air handling unit, send your specification here for pricing. If you don’t have a specification and any help with your cleanroom, contact us! A new air handling unit is just one of the services and products that we can offer for your cleanroom. The design of these air handling units needs to be taken into consideration with other modifications that may be required to facilitate your cleanroom upgrade such as ductwork, mechanical controls and chilling equipment for additional heat loads, if you have a specification for a new handling unit for your facility upgrade, please feel free to send it to us for pricing. If you don’t have an air handling unit specification some engineering will be required to ascertain what’s required to achieve the new cleanroom specification.

We are happy to assist you in gaining the details, and engineering required, to organize the required process below: The process to supply a suitable handling unit for a facility upgrade: Details need to be taken as to what is currently in existence, as you can imagine we may be able to design a system that is theoretically meant to provide suitable pressure on volumes, but in reality it accurate details are not found and considered the new handling unit may not operate correctly, details collected are likely to include air volumes drawings layouts air flow schematics details of balancing equipment available space to fit the new equipment in etc. Our engineering Department will undertake a gap analysis identifying what you have in existence and would be required to achieve your new cleanroom specification, taking into consideration, the items being reused. Our engineers will recommend what needs to be replaced, modified or reused. Consideration will be given to capital expenditure, installation costs, resultant effectiveness and ongoing efficiency.
