We take the heat out of your outage window.
Jason Group cleans, maintains and inspects the equipment your generation depends on — heat exchangers, condensers, cooling towers and the systems around them. Mobilised fast, documented properly, handed back on schedule.

What we do
Every hour a unit is offline has a number attached to it. Our operating model exists to make that number smaller.
Fouled tubes cost you backpressure. Backpressure costs you megawatts. We combine mechanical and chemical cleaning with in-house non-destructive testing, so the same crew that cleans the bundle can tell you what condition it is actually in — and put it in writing before you close up.
That single decision removes a second mobilisation, a second scaffold and, on most jobs, several days from the critical path.
How we work →Capabilities
Eleven disciplines,
one mobilisation.
- 01
Heat Exchanger Cleaning
Restore design-point thermal transfer across shell-and-tube, plate and air-cooled units.
Read more → - 02
Condenser Tube Cleaning
Pull back condenser backpressure and recover the megawatts fouling has been quietly costing you.
Read more → - 03
Retubing Services
From single-tube replacement to complete bundle retube, planned around your outage.
Read more → - 04
Cooling Tower Maintenance
Basin, fill and distribution deck cleaning, with structural inspection built into the same visit.
Read more → - 05
Industrial Cleaning
High-pressure water, dry vacuum and chemical cleaning across process equipment and structures.
Read more → - 06
Hydro Excavation
Non-destructive excavation around live utilities, buried lines and congested plant subsurface.
Read more →
Also: tank cleaning, decontamination, pipe cleaning, vacuum truck services and protective coating.

Inspection & integrity
Cleaning without data is just housekeeping.
Our certified inspectors work alongside the cleaning crews, so condition data is captured while access is already open — no second mobilisation, no second scaffold, no second outage.
-
AMPP Coating Inspection
Certified inspectors documenting surface preparation, application and holiday detection at every stage.
-
Eddy Current Testing
Non-destructive tube examination that maps wall loss, pitting and cracking before it becomes a forced outage.
-
Containment Leak Rate Testing
Local and integrated leak rate testing of containment penetrations, airlocks and isolation barriers.
How a job runs
Four steps, no surprises.
- 01
Scope
A call with someone who has done the work, not a salesperson. We ask what the unit is, what the symptom is and what the window is.
- 02
Plan
Written method statement, risk assessment, crew and equipment list, and a schedule that fits inside your outage — issued before mobilisation.
- 03
Execute
Crews on site with their own equipment, working inside your permit system and reporting against the schedule daily.
- 04
Hand back
Documentation package at handover: what was done, what condition it is in, and what we recommend for next outage.
Industries served
Regulated environments,
documented work.
- 01
Nuclear Power
Outage support, decontamination, containment testing and condenser work inside a nuclear quality programme.
- 02

- 03
Combined Cycle
HRSG cleaning, condenser services and balance-of-plant maintenance on short outage windows.
- 04

- 08
Heavy Manufacturing
Process cooling, exchangers and plant-wide industrial cleaning.
“They pulled two days out of a planned nine-day condenser clean and handed us the eddy current report before the unit came back up. That does not happen.”
