Energy Services
Energy Services for Business — One Partner for Fuel, Generators, Tanks and Oils
Most businesses don't need another fuel vendor. They need one partner who keeps the whole energy chain running — from the first liter of diesel to a clean tank, filtered fuel, the right industrial oil and a generator that starts when the grid doesn't. Dolek Energy brings every one of those services under one roof: diesel and heating-oil supply, generator fuel and backup, tank maintenance, industrial oils, on-site fueling and AdBlue — delivered nationwide, to standard, with 24/7 emergency response. This page is the map to all of them.

Why one energy partner beats a list of vendors
Energy is rarely a single purchase. A data center needs diesel for its generators, but also fuel polishing to keep that diesel within spec, tank cleaning before it degrades, transformer oil for its substation and emergency refueling when the grid fails. Handled by separate suppliers, every handoff becomes a gap — in scheduling, in accountability, in the documentation you need when something goes wrong. The fuel arrives from one company, the tank is serviced by another, and no one owns the outcome.
Dolek Energy is built on the opposite principle. We treat your energy supply as one continuous system and take responsibility for the full lifecycle — supply, storage, maintenance and emergency. That means a single point of contact, a consistent customer experience across the country, and one team that already knows your site when an urgent call comes in. We don't sell liters. We protect operational continuity, so the business simply keeps running.

Our energy services
Our services divide into six families. Each one stands on its own, and together they cover the entire energy chain of a business — so you never have to coordinate between providers or chase a different supplier for every need.
Fuel & heating-oil supply
Scheduled and on-demand supply of transport diesel, general-purpose diesel, winter heating oil and kerosene — delivered to specification and on time. Whether you run a generator fleet, an industrial boiler or a building's winter heating, we plan the supply around your consumption so a tank never runs dry at the wrong moment.
Generators & power
Diesel for backup generators, scheduled and emergency refueling, plus generator rental and sales with maintenance. For critical systems, fuel quality and a fast refuel are the difference between a clean failover and a costly outage — so we treat generator fuel as a continuity service, not a delivery.
Tank maintenance
Tank cleaning, fuel polishing and filtration, controlled waste evacuation with certificates, and periodic inspection of underground tanks. Diesel is a "living" fuel — it absorbs water, grows bacteria and forms sludge on the tank floor. Planned tank maintenance breaks that failure chain before the generator that depends on it ever needs to start.
On-site fueling
Fuel delivered directly to your equipment — heavy machinery, earthmoving fleets, cranes, forklifts, marine and emergency refueling — wherever the work is, around the clock. We keep construction sites, ports and field operations moving without the downtime and risk of sending equipment off-site to refuel.
Industrial oils
Transformer (dielectric) oil to IEC 60296, hydraulic oils (HLP 46 / HLP 68), heavy-duty engine oil, gear oils, grease and CNC fluids — supplied with COA/SDS documentation on request. The right oil, to the right standard, keeps transformers, hydraulics and machine tools running reliably.
AdBlue (urea)
AdBlue / urea solution for diesel vehicles, truck fleets and industrial SCR systems — supplied in packaged sizes and in bulk (IBC and larger), so fleets and plants stay compliant and uninterrupted.
Who we serve
These services support a wide range of operations, with the level of criticality shifting by use. Data centers and server farms depend on backup generators that must start without fail, so they need clean fuel, routine polishing and substation oil. Hospitals, institutions and public buildings rely on the same principle of dependable backup power. Industry and manufacturing plants run generators, boilers and machinery that demand steady fuel quality and the correct industrial oils. Winter institutions, residential buildings and hotels need clean heating oil ahead of the season. Construction and infrastructure sites require on-site fueling and hydraulic oils to keep heavy equipment productive. Haulage companies and vehicle fleets lean on stable fuel quality and AdBlue, and agriculture, moshavim and kibbutzim operate tanks, generators and pumps that all need supply and maintenance.
The common thread: energy is operational, not optional — and a single partner who understands the whole picture is the most reliable way to keep it running.
How working with us works
We work in a transparent, organized process, so you always know what is being done and why.
1. Tell us what you run
Share your site, equipment and consumption — generators, tanks, machinery, fleet or heating system. A quick assessment tells us which services fit.
2. Get a tailored plan
We map supply, maintenance and emergency cover into one plan, scheduled around your operation to minimize disruption.
3. We deliver and service
Fuel supply, on-site fueling, tank work and oils are carried out to standard, with documentation (COA/SDS, evacuation certificates) provided on request.
4. We stay on call
A single point of contact and a 24/7 emergency line mean that when something urgent happens, the team already knows your site.
Standards & compliance
Every product we supply is matched to the relevant standard, with documentation available on request. Diesel quality is measured against EN 590 for transport diesel and IS 701 Part 2 for heating oil; transformer oil follows IEC 60296; heavy-duty engine oils meet API CK-4; hydraulic oils conform to DIN 51524-2; and CNC and related fluids follow ISO 6743-7. On the maintenance side, underground tanks are subject to periodic tightness inspection, with a clear regulatory trend toward double-wall tanks. We support both sides of that equation — the technical work and the compliance — so your energy operation is protected operationally, environmentally and legally.

Frequently asked questions
What energy services does Dolek Energy provide?
We cover the full energy chain for businesses and institutions: diesel and heating-oil supply; generator fuel, backup and refueling; tank maintenance (cleaning, fuel polishing, evacuation and underground-tank inspection); industrial oils (transformer, hydraulic, engine, gear, grease and CNC fluids); on-site fueling for heavy equipment and fleets; and AdBlue. The point is to give you one accountable partner instead of a list of vendors.
Do you serve both small businesses and large institutions?
Yes. From residential buildings and private fueling stations to data centers, hospitals, plants and vehicle fleets — the services scale to the operation. We tailor the supply and maintenance plan to your site and consumption rather than offering one-size-fits-all packages.
Which standards do you work to?
Each product is supplied to its relevant international or Israeli standard — EN 590 for transport diesel, IS 701 Part 2 for heating oil, IEC 60296 for transformer oil, API CK-4 for heavy-duty engine oil, DIN 51524-2 for hydraulic oils and ISO 6743-7 for CNC and related fluids — with COA/SDS documentation provided on request.
Do you offer emergency and 24/7 service?
Yes. We operate a 24/7 emergency line for urgent supply, refueling and on-site response, including backup for generators in critical systems. Because we hold a single point of contact, the team already knows your site when an urgent call comes in.
What areas do you cover?
We work nationwide across Israel, with one service center and a consistent customer experience — from the center of the country to the north, Jerusalem and the south.
