RackWatt is a fully offline field toolkit for data center critical facilities technicians, operations engineers, and commissioning agents. Data halls are radio hostile and access controlled, so everything works with zero connectivity. THE METHOD OF PROCEDURE, DIGITIZED The core of RackWatt is procedure execution. Build or import a Method of Procedure, then execute it step by step. Initial every line, capture an automatic timestamp, add notes, photos, and readings, and finish with technician, peer reviewer, and manager signatures. Export a signed PDF record ready for the operations file. Pre execution guardrails confirm authorization, risk level, the current redundancy state, and the back out plan before any critical work begins. Pause or abort with a reason, and get a hard prompt to execute the back out plan. CALCULATORS THAT SHOW THEIR WORK A full power and cooling suite: UPS battery runtime, UPS sizing and loading, generator fuel runtime, three phase power, rack power density, power usage effectiveness, redundancy modeling for N, N plus 1, 2N, and 2N plus 1, arc flash awareness, airflow and heat load, delta T targets, airflow by density, and refrigeration. Every result shows the formula, the source, and the intermediate steps. EQUIPMENT TROUBLESHOOTING AND REFERENCE Searchable, offline reference across UPS, generators and transfer, electrical distribution, air cooling, monitoring, and the underserved liquid cooling edge: cold plates, manifolds, Coolant Distribution Units, rear door heat exchangers, and the hard won detail that mechanical seal life scales with discharge pressure. Every entry gives the warning signs and then an ordered list of what to check, most likely cause first. A UPS on bypass leads with the fact that the critical load is unprotected right now, even though it is still up. A generator that starts and then shuts down is kept separate from a no start, because fuel, battery and cranking are already proven and the diagnosis goes somewhere else entirely. Guided decision trees walk you through utility loss, unit on battery or bypass, breaker trips, high inlet temperature, cooling failures, abnormal delta T, leak alarms, and alarm storm triage, with red stops on safety critical steps. DOCUMENTS AND COMMISSIONING Standard and Emergency Operating Procedure libraries, commissioning levels one through five, rounds and readings with out of range flagging, preventive maintenance by asset class, work orders, incident and near miss reports, lockout tagout and energized work permits, arc flash and PPE assessments, and the change and risk record. Route any document to preset recipients. Emails queue and send when connectivity returns. SAFETY AND UPTIME DISCIPLINE Emergency power off, NFPA 70E awareness, and the discipline of never breaking redundancy without an approved procedure and a known back out plan. PRIVACY BY DESIGN No account, no cloud, no analytics, no ads, no third party SDK. Your procedures, records, and documents stay on device. RACKWATT PRO Free: the reference library, the three phase and delta T calculators, and signed records. Pro unlocks the other calculators, decision trees, redundancy model and procedures. $9.99 monthly or $79.99 yearly. The yearly plan starts with a 7 day free trial for first time subscribers; any unused part of the trial is forfeited if you subscribe during it. Payment is charged at confirmation, or when the trial ends, and renews automatically unless cancelled 24 hours before the period ends. Manage or cancel in Apple account settings. RackWatt is a field aid, not a substitute for the site approved procedures, the manufacturer manuals, NFPA 70E, the site arc flash study, or the engineer of record. Calculations are estimates to be verified by a qualified person.
