Total Cost of Ownership Calculator

The calculator combines four cost components over your selected time horizon (typically 10 years): (1) Capital cost — purchase price plus installation labor, including replacements when units reach end-of-life, (2) Electricity cost — average running watts × annual operating hours × your electricity rate, (3) Maintenance cost — typical annual service expenses, and (4) Expected downtime cost — probability-weighted risk based on each option's historical reliability. The result is the realistic 10-year cost of ownership for each option, not just the sticker price.

VoltAire air-conditioner pricing is published list price drawn live from our catalog. VoltAire heat exchangers are quote-only, so their capital costs in this tool are illustrative estimates (marked with an asterisk) until you request current pricing. Competitor pricing for OEM enclosure ACs is NOT publicly listed (most competitors are quote-only through distributors), so the calculator uses customer-reported typical purchase prices for equivalent OEM units in the U.S. market — these are estimates, and actual quoted pricing varies by distributor, region, and quantity. Electricity consumption is based on nameplate ratings adjusted for typical duty cycles. Maintenance estimates and reliability factors are derived from industry-typical service data, not statistically validated benchmarks. Use this calculator as a planning framework, not a binding cost estimate. For an accurate side-by-side, request a quote from your competitor and a quote from VoltAire and run the numbers with real values.

Three reasons: (1) lower purchase price, (2) dramatically lower electricity consumption — fans only, no compressor (typically 5-10x less power), and (3) longer service life with no compressor to wear out. The tradeoff is that heat exchangers can only cool to a few degrees above ambient, so they require ambient temperature lower than your target internal temperature to work.

Downtime cost varies enormously by application. Use these typical ranges: small PLC cabinet ($500-2,000/hour), industrial process line ($5,000-25,000/hour), telecom site ($1,000-10,000/hour depending on subscribers affected), data center ($10,000-100,000/hour). If unsure, use $2,000/hour as a conservative default — it's a common figure for industrial enclosure failures.

The "Do Nothing" baseline assumes no cooling investment but accounts for elevated equipment failure risk from running components above their rated temperatures. The 70% reliability assumption produces significant expected downtime cost. Real-world results vary widely — some operators run hot equipment for years without failure, while others see catastrophic component failure within months. Use this option as a conservative reference point.
