How much does a compressed air leak actually cost per year?

A single 1/4 inch leak at 100 psi can pass roughly 100 CFM and cost several thousand dollars a year in wasted compressor power. The Compressed Air Leak Loss calculator converts orifice size and pressure to CFM, then to kWh and dollars at your rate and running hours. Because leaks run 8,760 hours a year, a leak survey often finds 20 to 30 percent of total air demand is loss, making repairs one of the fastest utility paybacks available.

How do I quantify steam trap failure losses?

A failed-open trap blows live steam continuously, and loss scales with orifice size and pressure. Steam Trap Loss estimates pounds of steam per hour through the failed orifice, then Steam Leak Cost multiplies by boiler fuel cost per thousand pounds. A single 1/8 inch trap failed open at 100 psig can waste thousands of dollars annually, so surveying a population where 10 to 20 percent typically fail between checks builds a clear repair budget.

How do I convert a cooling load to refrigeration tons?

One refrigeration ton equals 12,000 BTU per hour of heat removal. The Refrigeration Tonnage calculator takes flow and temperature drop, or process heat load, and returns required tons. For chilled water, tons equal GPM times delta-T in Fahrenheit divided by 24. Pair it with Chiller Load and Process Cooling Capacity to confirm the plant has headroom, and with Refrigeration Energy per Unit to see the power cost of each ton at your operating conditions.

What is the boiler efficiency gap and why track it?

The Boiler Efficiency Gap is the difference between your boiler's design or best-achieved efficiency and its current running efficiency, driven by excess air, high stack temperature and scale. Even a 3 to 5 point drop raises fuel cost proportionally. Combine it with Boiler Blowdown Loss and Condensate Return Savings, since returning hot condensate and controlling blowdown both cut the makeup water and fuel needed to hold steam output.

How does peak demand drive my utility bill?

Utilities bill many plants on peak kW demand measured over a 15 or 30 minute interval, not just total kWh. The Utility Peak Burden calculator identifies which loads coincide at the peak, often chillers, compressors and large motors starting together. Staggering startups or shifting a chiller off the peak window can cut demand charges that persist for months, sometimes a larger saving than reducing overall consumption.

When does water reuse or treatment investment pay back?

Water Reuse Payback compares the capital and operating cost of reclaim equipment against saved intake, discharge and Utility Water Treatment Cost. In plants with high sewer surcharges or cooling tower blowdown, reused water can pay back in one to three years. Feed it Plant Water Use per Unit to normalize consumption against production and Utility Meter Coverage to confirm you are actually metering the streams the savings case depends on.
