CogenS™ — Cooling Tower Module
Cooling Tower Selection & Lifecycle Cost
Select and compare commercial and industrial cooling towers with proprietary CoolTools and YorkCalc performance models. Complete lifecycle cost analysis including water consumption, energy, and maintenance costs.
Why CogenS™
Beyond Equipment Selection. Total System Economics.
Cooling tower selection impacts far more than equipment cost. Water consumption, fan energy, chemical treatment, and maintenance drive the majority of lifetime costs. The right tower for your climate and load profile may not be the cheapest one.
CogenS™ uses proprietary CoolTools and YorkCalc performance models with local TMY weather data to simulate real-world cooling tower performance hour by hour -- revealing the true total cost of ownership.
Capabilities
Complete Cooling Tower Analysis
Integrated performance modeling, water cost analysis, and lifecycle economics.
All Major Tower Configurations
Open and closed circuit cooling towers. Centrifugal and axial fans. Counterflow and crossflow designs. Single-speed, two-speed, and variable speed controls for optimal energy modeling.
Proprietary Performance Models
Built-in CoolTools (35-coefficient) and YorkCalc (27-coefficient) vendor performance models for accurate capacity and efficiency simulation across varying wet bulb conditions and load ratios.
Water Cost Analysis
Tiered water and wastewater billing for cooling tower makeup water. Evaporation rates, blowdown cycles, and drift losses calculated hourly. Fixed charges, volume tiers, and seasonal adjustments included.
Integrated Chiller Coupling
Cooling towers are automatically paired with water-cooled chiller selections. Analyze the complete chiller-tower system as a unit for accurate total cost of ownership.

Why It Matters
Solving the Hardest Parts of Cooling Tower Selection
Open vs Closed Circuit
Open circuit towers are cheaper but expose process water to contamination. Closed circuit towers protect water quality but cost more. CogenS™ quantifies the lifecycle cost trade-off for your specific application.
Water Consumption & Cost
Cooling towers consume significant water through evaporation, blowdown, and drift. Water and wastewater costs can represent 10-20% of total operating cost. CogenS™ models tiered water billing for accurate projections.
Fan Control Strategy
Single-speed, two-speed, and variable speed fans dramatically affect energy consumption and noise levels. CogenS™ simulates hourly fan power across the full range of wet bulb conditions your site experiences.
