Cooling Tower Replacement: Efficient Heat Rejection

Cooling towers are the critical link between your chillers and the atmosphere. When towers deteriorate, chiller efficiency suffers, water consumption increases, and the risk of Legionella contamination rises.

We manage complete cooling tower replacement projects from equipment selection through commissioning. Whether you need a simple like-for-like replacement or an upgrade to more efficient, quieter technology, our team ensures minimal downtime and optimal integration with your existing systems.

Improved efficiency

Modern towers with high-efficiency fills and VFD fans reduce condenser water temperatures, allowing chillers to operate more efficiently and consume less electricity.

Water conservation

Advanced drift eliminators reduce water loss to less than 0.001% of circulation rate. Better water treatment compatibility means fewer blowdown cycles and lower water consumption.

Health & safety

New towers with proper drift eliminators and designs that support effective water treatment significantly reduce Legionella risk and support regulatory compliance.

Types of cooling towers

Different buildings have different requirements based on capacity, space, noise sensitivity, and existing infrastructure. We work with all common tower configurations.

Induced Draft

Fans on top pull air through the fill. Most common type for condo buildings. Efficient and relatively quiet.

Forced Draft

Fans push air into the tower from below. Good for retrofit situations with height restrictions.

Crossflow

Air flows horizontally through falling water. Lower pump head requirement, easier maintenance access.

Counterflow

Air flows upward against falling water. More thermally efficient, smaller footprint.

Closed Circuit

Water in closed coils, no direct contact with air. Used where water quality is critical.

Hybrid/Adiabatic

Dry coolers with evaporative assist. Reduced water use, good for water-restricted sites.

Deteriorating cooling tower requiring replacement

Why proactive tower replacement?

Cooling towers operate in harsh conditions—constant water exposure, summer heat, winter freeze cycles, and airborne contaminants. Deterioration is inevitable, and the consequences of failure are severe.

  • Chiller efficiency: Degraded towers deliver warmer condenser water, forcing chillers to work harder. Every 1°F increase in condenser water temperature costs 2-3% in chiller efficiency.
  • Legionella risk: Old towers with deteriorated drift eliminators, dead legs, and areas difficult to treat create Legionella risk. Modern towers are designed for effective water treatment.
  • Structural safety: Corroded basins and supports can fail catastrophically. The weight of a full cooling tower on a compromised structure is a serious safety hazard.
  • Noise complaints: Worn bearings, unbalanced fans, and deteriorated components increase noise levels, often leading to resident complaints and municipal noise bylaw issues.

FAQs

Equipment lead times currently range from 10-20 weeks depending on manufacturer, size, and material (galvanized vs. stainless vs. FRP). Once equipment arrives, on-site work typically takes 2-4 weeks from old tower removal to new tower commissioning. We coordinate crane operations, often completing the swap in a single day to minimize cooling system downtime.

Cooling towers reject heat from the chiller condenser. Degraded towers deliver warmer water to the chiller, forcing it to work harder. Modern towers with efficient fills and proper airflow deliver cooler condenser water—every 1°F improvement translates to 2-3% better chiller efficiency. For a building spending $50,000/year on cooling, this can mean $5,000-15,000 in annual savings.

Legionella is a serious concern for cooling towers. New towers are designed with proper drift eliminators (reducing aerosol release), accessible basins and components (enabling effective cleaning), and configurations that support proper water treatment. We coordinate with water treatment providers to ensure the new system is properly set up and that your ongoing treatment program is effective.

For buildings with multiple cooling towers, we can stage replacement to maintain partial capacity. For single-tower buildings, we typically schedule during spring or fall when cooling demand is minimal. The actual tower swap often takes only 1-2 days. If summer replacement is unavoidable, temporary cooling solutions can be arranged.

Fiberglass reinforced plastic (FRP) towers offer superior corrosion resistance and typically last 25-30+ years with minimal maintenance. Galvanized towers cost less initially but are susceptible to corrosion and typically last 15-20 years. Stainless steel falls in between. For most Toronto condos, FRP offers the best long-term value despite higher initial cost.

Costs depend on tower capacity, material (galvanized, stainless, FRP), crane requirements, and piping modifications needed. Typical projects range from $75,000 for smaller towers to $300,000+ for large multi-cell installations. FRP construction adds 20-40% to equipment cost but offers significantly longer life. We provide detailed proposals after site assessment.
