Forestry fuel polishing

Diesel is the lifeblood of a harvesting operation, and Northland is hard on it. The climate is warm and humid, rain is heavy, and fuel lives in tanks, trailers and pods parked on exposed skid sites. Every temperature swing pulls moist air in, condensation collects in the bottom of the tank, and diesel bug grows where water meets fuel.

Then the sludge goes into a harvester, processor, skidder or loader with a high-pressure common-rail fuel system. Blocked filters stop the machine. Contaminated fuel can damage injectors and pumps, and most engine warranties exclude damage caused by dirty fuel.

Why polishing beats dumping on a forestry block

When fuel on a remote site goes bad, the usual answer is to pump it out, cart it away and truck in replacement diesel. That’s expensive, slow and an environmental risk on a forestry block. Our rule-of-thumb estimate: disposing of and replacing a 5,000 L tank costs around $20,000, against roughly $5,000 for polishing and a maintenance programme, before you count a crew standing idle.

Polishing cleans the fuel you already have, where it sits.

How we work on forestry sites

1. Test each tank at three depths, including fuel trailers and service trucks.
2. Polish the fuel through our filters and coalescer, with high-flow lances to break up sludge, and return it clean.
3. Advise on breathers, filling practice, outlet filtration and where tanks are parked.
4. Maintain on a schedule that fits your harvest moves, so fuel stays clean from one block to the next.

We work with harvesting contractors, roading and earthworks crews, forest managers and log yards.

Standby generator fuel polishing

Northland knows what a long outage looks like. Cyclone Gabrielle in 2023 left communities across the region without power for days, and generators that had sat for years didn’t always start, or stopped once old fuel from the bottom of the tank reached the filters.

Cyclone season runs from November to April, so now is the time to check. We look after generator diesel for:

• Rural homes, lifestyle blocks and farms
• Marae and community halls that act as welfare centres
• Medical centres, aged care and schools
• Orchards, packhouses and cool stores
• Dairy sheds and water pumping
• Water treatment, council and telecommunications sites

We test the fuel, polish it back to clean and set up a maintenance plan, with remote monitoring for critical sites.

Other diesel we look after in Northland

• Boats: launches, yachts, charter, dive and fishing vessels in the Bay of Islands, Whangārei Town Basin, Tutukākā and Mangōnui
• Orchard and farm irrigation pumps
• Quarries, civil contractors and earthmoving plant
• Transport yards and bulk diesel storage

Areas we cover

Whangārei, Kerikeri, Paihia, Russell, Kaikohe, Kawakawa, Kaitaia, Mangōnui, Dargaville, Ruawai, Maungaturoto, Mangawhai, Ruakākā and the wider Far North, Whangārei and Kaipara districts.
