Cool room repairs in Henderson
Sam Celesti covers Henderson for cool room, freezer room and commercial fridge repairs. Henderson sits about 25 km from the Perth CBD on the shore of Cockburn Sound, and it is almost entirely industrial. Sam is ARCtick licensed (AU55592), has more than 20 years in commercial refrigeration, and quotes a fixed price before any work begins. He is happy to complete site inductions and work within your permit system.
Grit, fumes and a choked condenser
The local angle in Henderson is what is in the air. Shipbuilding, steel fabrication, abrasive blasting and engineering workshops fill the area with fine metal dust, grit and welding fumes. A condensing unit pulls a large volume of air through its coil every minute, and that air leaves a film behind. Add sea moisture blowing in off Cockburn Sound, plus a bit of oily residue from nearby plant, and the dust bakes onto the fins as a dark crust.
The result is the same as a coil blocked by leaves, only faster and harder to clean. Airflow drops, the refrigerant cannot shed its heat, and head pressure climbs. The compressor runs hotter, draws more current and trips on overload on warm afternoons. Metal particles also lodge in fan motors and electrical contacts, and some dust is corrosive once it gets wet, so fins and connections deteriorate early.
Sam deals with this in a few ways:
- A thorough coil clean with the right chemical, not a quick blast with a hose that drives grit deeper.
- Checking condenser fan motors, contactors and compressor windings for heat damage.
- Advising on shielding or relocating a unit that sits downwind of a blasting bay or grinding area.
- Setting a cleaning interval that suits the site, through planned maintenance.
Who needs refrigeration around the marine complex
The Australian Marine Complex and the surrounding Henderson industrial area employ a large workforce, much of it on shifts. That workforce eats on site, so refrigeration is everywhere even though food is not the main business. Site canteens and crib rooms run walk-in cool rooms, under-bench fridges, drinks fridges and ice machines. Contract caterers keep cool rooms and freezer rooms stocked for daily meals. Lunch bars and food trucks serving the area need reliable fridges from early morning.
Further along the coast toward Cockburn Sound's fishing and aquaculture activity, seafood handlers rely on freezers, cool rooms and flake ice. Engineering suppliers and logistics yards round out the area, and some keep a small cool room or a row of drinks fridges for staff through the hot months. Each of these sites sees heavy door traffic, long operating hours and a dusty environment, which together wear out seals, fans and compressors faster than in a suburban shop.
If the cool room fails on site
Tell the person running the canteen or kitchen to stop restocking the room until it is pulling down again. Then walk out to the condensing unit, see whether it is running and whether the coil is visibly caked, and photograph the coil and the controller display. Those photos help Sam judge what is wrong over the phone.
Check the food for the next shift with a probe. FSANZ guidance keeps potentially hazardous food at 5°C or colder. Where it has been between 5°C and 60°C for under 2 hours, return it to a working fridge; for 2 to 4 hours, serve it now; for 4 hours or longer, throw it out. Log the readings so the site has a record.
Ice machines in crib rooms are covered by our ice machine repair service, and when a system keeps losing gas, Sam can locate the leak and recharge it with a refrigeration regas. For an overview of the faults involved, see Perth cool room repairs.
