Tiered annual maintenance contracts and preventive-maintenance programs that keep every centrifugal fan on your site running — whoever built it. You get scheduled visits, a response SLA and ISO 21940 balancing on one contract, in place of ad-hoc breakdown spend.
839 service events over 12 years.
Most fan-maintenance offers stop at the maker's own machines. Jitamitra's do not: our annual maintenance contracts and preventive-maintenance programs cover any make of centrifugal fan, so a single contract can span a mixed fleet — our fans, a competitor's, obsolete and orphaned units alike. You trade unplanned breakdown spend for a guaranteed service cadence, a promised response time and a fixed annual cost.
Because we design, build and overhaul fans in-house, each scheduled visit runs documented maintenance procedures — bearing-temperature and vibration rounds, lubrication, motor-current checks, and impeller and blade-root inspection — and any rotor we touch is re-balanced to ISO 21940 grades before the fan goes back to duty. Faults get caught on the calendar, not on the breakdown call, and every visit lands as a written report in your maintenance log.
Wrap scheduled preventive visits, an agreed spares arrangement and a response SLA into a multi-year contract, tiered from a basic plan up to sensor-bundled cover, on any make of centrifugal fan. Each visit runs the same documented maintenance procedures and re-balances rotors to ISO 21940 grades where work is done. You get a guaranteed service cadence, priority response and a fixed annual cost in place of ad-hoc breakdown spend.
Standard/method. Underlying maintenance follows Jitamitra Manual Section 7; re-balancing to ISO 21940 / ISO 21940 grades (G6.3 general, G2.5 critical) and vibration assessment to ISO 14694 (BV-3) where applicable. The AMC itself is a commercial contract, not a technical standard.
Run scheduled site visits on a duty-based calendar — regreasing bearings, logging bearing-temperature and vibration monthly, checking three-phase motor current quarterly (any phase imbalance over 5% investigated), and inspecting the impeller for deposit and blade-root cracks. Every finding is written to a documented inspection report and your maintenance log, with blades flagged for replacement past 20% erosion and rotors re-balanced to ISO 21940 G6.3/G2.5 after any work. It covers any make of centrifugal fan, so one program spans a mixed fleet.
Standard/method. ISO 21940 / ISO 21940 (balance grades G6.3 general, G2.5 API/critical, applied when a re-balance is done). Vibration assessment references ISO 14694 acceptance limits (BV-3). Lubrication, inspection and overhaul follow Jitamitra Manual Section 7 procedures.
Building a network of vetted independent service firms, certified and trained to our own maintenance and balancing standards (ISO 21940 / ISO 14694), to deliver fan service under the Jitamitra brand closer to your site. The model runs both ways — we authorise partners, or serve as an authorised partner for another OEM — extending brand-backed coverage without local payroll. This is a capability in development, offered on enquiry, not an operating network today.
Standard/method. No product test standard governs the channel model itself. Partner service quality would be benchmarked to Jitamitra's service basis - ISO 21940 balance grades and ISO 14694 vibration acceptance for the field work partners perform - but the network's certification, audit and brand-governance criteria are commercial terms, not a published standard.
