━ REFILLING · COLLECTION & RETURN
Extinguisher refilling and maintenance contracts, done on a bench not a doorstep.
DCP, CO₂, AFFF, water and clean-agent cylinders collected from your site, refilled and tested at the Serai Road workshop, then returned with a dated tag and a receipt.

WHAT WE REFILL
Every agent we service, and what the refill involves.
Agent grade is matched to the risk and to the cylinder’s own rating — not to what happens to be in stock.
DCP - ABC powder
Multipurpose monoammonium phosphate for paper, wood, cloth, plastics and electrical equipment. Weighed to the stamped capacity, then nitrogen charged.
DCP - BC powder
Sodium bicarbonate based, for gas, oil and electrical fires where the residue of ABC powder would damage equipment.
CO2
Clean, residue-free discharge for server rooms, labs and electrical panels. Cylinders are weighed before and after filling.
AFFF foam
Aqueous film-forming foam settled on hydrocarbon fires — fuel storage, generators and workshops. Ratio checked against the cylinder’s rating.
Water & wet chemical
Water for Class A, wet chemical for kitchen oil fires in commercial kitchens and hotels.
Clean agent & Halotron
FM-200 and Halotron cylinders for sensitive rooms where a dry powder discharge would write off the equipment.
THE REFILL, STEP BY STEP
What happens to your cylinder while it is with us.
Nine steps. The ones that get skipped in a cheap refill are exactly the ones that make an extinguisher fail when it is needed.
Depressurise
Residual pressure discharged safely before any work begins — never worked on live.
Empty & dispose
Old agent fully removed and disposed of, never topped up over compacted powder.
Inspect shell
Internal and external check for corrosion, dents and pitting. Condemned shells are reported, not refilled.
Strip the valve
Valve, siphon tube, spring and stem removed, cleaned and inspected.
Replace seals
O-rings and worn components renewed so the cylinder holds pressure.
Refill & re-weigh
Correct agent grade filled to stamped capacity and weighed, not eyeballed.
Re-pressurise
Nitrogen charged to manufacturer pressure and held to confirm no leak.
Seal & tag
New tamper seal, dated tag and entry in your log book.
Return & hand over
Cylinders go back on the scheduled run, refitted in position and signed off against your register.
ANNUAL CONTRACTS

Included in every contract
- Scheduled visits booked around your operations, not ours
- Dated tag on every cylinder and a signed visit report
- Register and log book kept up to date
- Priority on fault and emergency calls
- Refills as due within the agreed allowance
Quoted separately
- Cylinders condemned at inspection (replacement, not repair)
- Hydrostatic testing outside the cycle
- New installations and additional equipment
- Damage caused by discharge, misuse or third-party work
A refill is not topping up powder through a funnel.
Done properly it is a nine-step process with a weighed fill, a pressure test and a record. If you are being quoted well below market, ask which of those steps is being left out. Weighed fill Nitrogen charged Tamper sealed Dated tag Log book entry
QUESTIONS
Refilling, asked before the first collection.
How often should extinguishers be refilled?
Is refilling done on site?
How long does a collection and return take?
Can you refill a cylinder that has been in storage for years?
Do you supply the extinguishers as well as refill them?
What does an annual maintenance contract cover?
Do you cover Hyderabad and Nooriabad?
Can you work outside working hours?
COVERAGE
Collection and return across the city.
Our workshop sits inside the city rather than on its edge, so cylinders spend less time in a vehicle and more time being worked on. Outside the city, equipment ships by courier.
Industrial estates
Factories in Nooriabad, Jamshoro and the Hyderabad belt are served on a scheduled route rather than a same-day promise — the drive is roughly two hours each way. For plant-wide contracts we survey once and then run scheduled visits, so your team is not chasing several suppliers across a dozen buildings.

FREE SITE ASSESSMENT
Tell us what is on site. We will scope it in writing.
Send cylinder counts, panel make, or a photo of the label — that is usually enough to come back with a real number instead of a range.

NEED A DECISION TODAY?
Three ways to reach us, depending on what you need.
A fault at 2am and a new-installation quote are different problems — so they come in through different doors.
Talk to an engineer
