Critical power · zero margin for error

Critical power. Zero diesel. Zero noise.

Q: How does this compare to our existing UPS + DG combo?

Today: UPS holds the load for 5–10 seconds while the DG starts. Lead-acid UPS batteries need replacement every 3–4 years. With BESS: under-10 ms transfer on an MTX Hybrid critical bus (PTX sites use PCC switching engineered to your single-line design), LFP cells rated ~6,000–8,000 cycles, and runtime sized to your outage profile without any DG start. Many hospitals shrink or retire the lead-acid UPS once BESS commissions.

Q: Will the BESS handle MRI / CT load spikes?

Yes, when sized for it. A PTX-250 runs two 125 kW power modules (250 kW rated, 275 kW max) with 100% unbalanced-load capability. We check MRI, CT and X-ray inrush data during design; imaging-heavy campuses step up to a PTX-500.

Q: What if we lose grid for 6+ hours?

Most deployments keep a smaller standby DG (say 60–100 kVA, BESS-charged when grid returns) for the rare multi-hour case. The BESS handles the bulk of short outages; the DG only spins up beyond the runtime you size for. Net diesel consumption drops 75–85%.

Q: Can we integrate the BESS alarms into our existing BMS?

Yes. The TOBOR EMS exposes Modbus TCP, BACnet IP, and SNMP. Most hospital BMS dashboards have the BESS state (SoC, kW, alarms) pulled in within 1 week of commissioning.

Q: What's the cost vs continuing with our current DG + UPS setup?

Capex on a PTX-250 (250 kW / 257.2 kWh) + light retrofit is typically ₹55–75L (depends on cabling and switchgear). Compare against ongoing DG fuel + UPS replacement + CPCB CEMS — payback is 3.5–4 years. After year 4, savings stay yours for 12+ more years.

Hospitals can't afford 5-second DG warm-ups during a code-blue. 4-star hotels can't afford diesel smell drifting into the lobby. TOBOR BESS gives you under-10 ms transfer on MTX Hybrid critical buses and silent, fume-free runtime sized to your outage profile — every day.

Annual savings

₹14L+ / year

Payback in 3.5–4 years on a PTX-250 (250 kW / 257.2 kWh). The harder-to-quantify upside: no DG warm-up gap during a procedure.

Built for this

Why operators in this segment pick TOBOR.

Fast transfer for OT / ICU

Operating theatres, ventilators, MRI, cold-chain — none of them tolerate a 5-second DG warm-up. The MTX Hybrid switches its critical bus in under 10 ms; PTX systems transfer through PCC switching engineered to your single-line diagram.

Silent operation

No engine, no exhaust stack — just cooling fans. Guest-facing hotel zones stay quiet during outages. Hospital wards don't get a DG roar through the night.

Zero local emissions

No NO₂, no PM2.5, no diesel smell drifting through hotel lobbies or hospital corridors. Pollution Control Board audit risk eliminated.

Replaces lead-acid UPS too

Many hospitals run a separate lead-acid UPS for critical loads. An MTX Hybrid critical bus covers fast transfer and DG-class endurance on one platform; on PTX sites we size the UPS down to the most sensitive loads.

Pairs with critical-load segregation

Most hospitals already split critical (OT, ICU, lifts) vs non-critical (admin, F&B). BESS sits on the critical bus; existing DG can stay for non-critical multi-hour backup.

8,000-cycle LFP · modular power

PTX-250 and up run 314 Ah LFP cells rated ~8,000 cycles. Power is built from paralleled 125 kW modules, so capacity grows with the campus.
