Evaporative Cooling Systems
Visibility into efficiency for cooling towers, evaporative condensers, and other air conditioning systems can lead to big mechanical and operations savings.
Out of sight but not out of mind.
Heat exchangers that use water like cooling towers, evaporative condensers, swamp coolers, and other evaporative equipment are complex. The number of potential failure points are many.
This equipment is often out of sight, either on rooftops or in secure areas accessible by qualified staff only. When hardware sensors fail –and they will –the event often appears as a ‘false-positive’ on existing alarm screens. When issues go undiscovered, the impact from equipment failure or unexpected downtime can be significant.
…Now we can see things and figure out what is going on. This saves service visits, water, and makes the equipment last a lot longer.

See what you’re missing.
Water use monitoring and analysis in real time lets you see mechanical, operational, and process failures early. When an event is detected, staff and service providers get the actionable information when they need it to diagnose and repair the issue the first time.
An enterprise-grade dashboard accessible 24/7 makes portfolio-wide comparisons possible. Performance differences between assets and facilities become obvious. Data gives you visibility to help understand why.
Now you can achieve corporate cost reduction targets, and drive toward efficiency and sustainability goals with confidence.
Get evaporative credit where it’s due.
Offered by water and sewer utilities, evaporative credits offset the cost of sewer fees for water that has evaporated in the cooling process. These are often available but frequently overlooked.
Apana monitors heat exchanger water make-up and sump discharge blow-down.
Using this data, evaportion rates are easily calculated so you can claim the credits.
If credits are available from your utility, the service often pays for itself in 12 months or less.
From detection to resolution in under 4 hrs.
Blowdown valves are a common failure point. Because most are designed to fail open, water can flow constantly from the heat exchanger sump with a ‘false-positive’ signal being sent to the alarm screen. This type of failure is often missed during routine inspections, so water waste can continue for a long time.
In this example, Apana identified an issue early and sent an alert to maintenance staff with easy to follow guidance. Critical information was provided so the appropriate technician was able to make repairs the first time.
Simple, step-by-step instructions.
Whether it’s an everyday wasteful practice or a one-time leak, you can’t fix what you can’t see. We monitor your operations 24/7 and send instant email notifications when waste is detected, so you’re always in the know.

Descriptive and actionable.
Emails have a standard “at a glance” format designed to allow managers to delegate follow-up with clear, practical guidance.
Real-time data. Big-time insights.
Water data visualization provides additional context showing the exact time and severity of the problem.
Practical trouble-shooting steps.
Non-technical site staff are shown how to triage problems and call the correct service provider if there’s not an easy fix.
