Thermal Performance:

2.1

The tower shall be capable of cooling

 

_____ GPM of water from ____ °F to

 

_____ °F at a design entering air wet-

 

bulb temperature of _____ °F. The cool-

 

ing tower manufacturer shall guarantee

 

that the tower supplied will meet

 

the specified performance conditions

 

when the tower is installed according

 

to plans.

2.2

The purchaser will arrange for an

 

on-site thermal performance test, to

 

be conducted in the presence of the

 

manufacturer and owner, and under

 

the supervision of a qualified, disinter-

 

ested third party in accordance with

 

CTI (Cooling Technology Institute) ATC-

 

105 standards during the first full year

 

of operation. If the tower fails to per-

 

form within the limits of test tolerance,

 

then the cooling tower manufacturer

 

will install additional cells and/or make

 

such corrections as are agreeable to

 

the owner and shall pay for the cost of

 

a retest. If the tower still fails to per-

 

form as specified, then the manufac-

 

turer shall make such reimbursements

 

as are appropriate and agreeable to the

■Your reason for purchasing a cooling tower is to obtain a continuing flow of cooled water as defined in the first paragraph at left. If the tower that you purchase is incapable of performing as specified, then you will not have received full value for your money.

Bear in mind that the size—and cost—of a cooling tower varies directly with its true thermal capability. This paragraph is intended to protect you against either intentional or inadvertent under sizing of the tower by the manufacturer. Judging the level of performance of a cooling tower on critical processes is never easy, and the potential risk of a non-performing cooling tower usually causes the requirement for a mandatory acceptance test to be very desirable.

Your contract with the successful bidder should establish the accept- able remedies for missed performance, which might include:

•The addition of one or more cells of tower, as necessary, to bring the cooling tower to the specified level of performance. This is usually limited to the scope of work as defined in the specs, which means that you (the owner) will have to pay for the additional basin, wiring, start- ers, piping, etc.

•The reimbursement of a portion of the total contract price equal to the percentage deficiency in performance.

Under no circumstances should you allow the manufacturer to re-pitch the fans to increase motor brake horsepower above that shown in the proposal. That creates additional operating costs that will continue for the life of the tower—and imposes no penalty on the manufacturer.
