B.P. - TOWER REPAIR

image
PROJECT DETAILS

The three cell tower was originally designed as a wet/dry cooling tower, with mechanically operated internal dampers to reduce the plume.

Each cell was fitted with a 12’ wide x 30’ high finned coil on one side of the tower and the opposite side of the tower consisted of Vee bar with 16’ air travel.

The return water from the process was pumped through the finned coil and then through the cross over pipe and into the hot water basin.

With plume abatement no longer an issue the system was redesigned by Colt Engineering to cool 13,500 USGPM from 95 to 80 @ 73 wet bulb, and the project consisted of the following modifications;

  • All the finned coils were completely removed
  • New 20’ diameter FRP fans were installed for maximum airflow
  • New hot water basins and nozzles to match water flow
  • New FRP louvers
  • New hangers and Vee bar
  • Structural repairs

McMASTER UNIVERSITY - 2 CELL ADDITION

image
PROJECT DETAILS

The customer required an additional cooling tower be added to the following design conditions:

Flow: 3,395 usgpm
Entering Water: 95.0°F
Leaving Water: 85.0°F
Wet Bulb: 76.0°F

Site Conditions:
Install new packaged steel or build additional cells onto the existing cross flow induced draft wood tower.

The last photograph is standing on the existing fan deck of the original tower looking at the new two cell addition. We had reconstructed the original tower and added the new fibreglass fan stacks in previous years. Note: New Hot water basin joins to original hot water basin forming one complete tower.

The third photograph shows the existing tower and in the background with the new safety railing are the new CTM cells that were added to the existing.

EATON'S CENTER SHOPPING MALL - TOWER REPLACEMENT

image
PROJECT DETAILS

Original Equipment: 2 cell Marley Series 15; installed 1975; Designed HH Angus
Design Conditions: 6,600 usgpm
Entering Water: 95ºF
Leaving Water: 85ºF
Wet Bulb: 76ºF

Site Conditions:
Because the system is heat recovery, the cooling tower operates all year long therefore we were required to rebuild the system while the chilled water plant continued to operate throughout the winter months.

The towers are located on the roof 35 stories above grade at the corner of Yonge and Dundas Street. Crane lifts were unreasonable given the site conditions and the height.

Photographs are of the first phase of the project. The first shot shows the January 2004 completion of a section of the tower while the dilapidated original section continues to operate. The second shot is of the fibreglass casing and access door that replaced the original MNA asbestos casing. Note the new fibreglass fan stacks protruding from the top of the tower.

CONOCO PHILLIPS - TOWER COLLAPSE

image
PROJECT DETAILS

The 63,000 USGPM, 9 cell single flow cross flow tower located in Burstal about 120 KM north of Medicine Hat in Alberta was struck by a tornado in July of 2005 which resulted in the total collapse of all 9 cells and the entire plant had to be shut down.

We visited the job site and with in days of the collapse we were part of the team involved in supplying and setting up over 30 portable rental cooling towers which were piped into the existing sump, allowing the plant to be in operation within 6 weeks of the collapse.

The rental towers were in operation for approximately 2 months while a new cooling tower was erected within the original concrete basin.

PROJECT DETAILS

Original Equipment: 2 x 3 cell Marley Series 10; Installed 1970;
Designed ECE Group Design Conditions: 4,150 usgpm
Entering Water: 105/95ºF
Leaving Water: 85ºF
Wet Bulb: 76ºF

Site Conditions: Because the system is heat recovery, one bank of cooling towers operate all year long therefore we were required to rebuild the system while the chilled water plant continued to operate throughout the winter months.

The towers are located on the roof 56 stories above grade at the corner of Bay and King Street. Crane lifts were unreasonable given the site conditions and the height.

TORONTO STAR BUILDING - NEW TOWER REPLACEMENT

image
PROJECT DETAILS

The existing three cell Series 10 Marley Cooling Tower was in poor condition and had to be replaced without interruption to the operation of the plant,

This was achieved by keeping two cells in operation at all times while each cell was completely removed and replaced.

In addition to the tower replacement, the concrete piers were repaired and new hot dipped galvanized supporting steel was replaced at the same time.

The new three cell Midwest Cross Flow Tower was designed to cool 4000 USGPM from 100 to 85 @ 76 wet bulb temperature.

ORFORD STACK

PROJECT DETAILS

This is a one of a kind natural draft cooling tower which was built in 1974 and is located at INCO in Sudbury.

The scope of work involved the complete removal of the entire asbestos cement casing panels, drift eliminators, heat transfer surface and spray system.

These asbestos components were replaced with fiberglass casing, high efficiency PVC eliminators, high efficiency cross fluted PVC heat transfer media and Schedule 40 PVC spray system and nozzles.

In addition to this there was significant degradation and spalding of the concrete sump and supporting concrete columns and beams.

The columns were cleaned up and fitted with Stainless forms and filled with high strength fast drying specialty grout, all concrete beams were replaced with Steel beams and the concrete inlet louvers were replaced using marine grade pressure treated plywood complete with a steel guard rail.

The bulk of the work as done during the summer shutdown in 2005 & 2006, however much of the upper level columns were done over the winter with the tower online in conditions well below -20 Celsius.

PROJECT TESTIMONIALS

"Your company attained an outstanding safety record of zero injuries over the entire construction period. We look forward to working with you in the near future in the hope of achieving similar safety results. "
