The City of Taylor is accepting bids for modifications to the Taylor Sportsplex refrigeration plant.
The modification will involve the following;
Evaporative condenser.
Removal and disposal of the existing model number Frick XLP-XL 710 condenser, supply and installation Frick model number XLP3-12180533-030 (or similar) flooded sump evaporative condenser. The replacement condenser must be suitable for winter operation. (The Frick condenser was selected due to the dimensions match the existing support structure)
Remote sump.
Removal and disposal of the existing remote condenser water sump and condenser water pump.
Condenser water pumps and components.
Supply and Install two (2) new condenser water pumps, strainers and isolation valves, each sized to meet flow specifications of the replacement evaporative condenser. The condenser water pumps are to be located on the remote sump pad.
Condenser fan motor speeded drive(s).
Supply and install condenser fan motor speed drive(s). Output from each speed drive to the condenser fan motor(s) are to be run in separate conduit(s). Control of the speed drive(s) is to be coordinated with CIMCO Automation Group.
Controls.
Supply and installation of condenser sump heater, sump level control, motorized condenser water makeup valve and motorized blowdown and freeze protection valves. Automation and control of the plant is to be coordinated with CIMCO Automation Group.
Mechanical.
o Contractor is to supply all labor, components, machinery and equipment necessary to perform the tasks listed above.
