ACTC Replace Cooling Tower

The existing cooling tower is nearing the end of its useful life. The packing and piping of the cooling tower has noticeable scale build-up, which negatively affects the efficiency of the tower. The galvanized steel basin has rust build up which causes contamination of the water and could lead to severe damage to the (2) condenser pumps serving the system. The existing cooling tower will be replaced with an updated multi-cell model that has the same capacity, while reusing the existing chiller. This means the majority of the above grade existing condenser water piping will need to be replaced to accommodate the new tower. The existing fan starters will be removed along with the associated controls specific to the existing cooling tower. The new multi-cell cooling tower is designed to meet the full cooling demand of building. However, if one of the cells requires maintenance or is having issues, we will be able to isolate the cell while the other is still in operation. Whisper Quiet propellers will be used for sound attenuation which are much quieter compared to the existing aluminum propellers. The basin would be constructed of 304 Stainless Steel. This is covered by a 5-year leak warranty. The overall footprint of the new tower will require the existing concrete pad to be extended to the existing retaining wall. All electrical connections/controls will be located in the basement mechanical room. New motor starters for each fan will be located in the existing Motor Control Center and each fan will have its own VFD.
