Municipal sanitation directors rarely get to electrify an entire department in one budget year. The practical question is always: which electric truck first? For most cities the answer lies between two machines in the Dongfeng sanitation line-up — the KT1D electric garbage truck, which collects the waste, and the KT3E electric road sweeper, which cleans the streets the waste trucks drive on. Both run CATL LFP batteries, both eliminate the high-idle diesel duty that makes sanitation the worst fuel economy in any fleet, and both carry the 8-year/4,500-cycle battery warranty. But they solve different problems, consume energy differently, and pay back on different timelines. This comparison lays out the spec-by-spec differences, the duty-cycle realities, and a budget-splitting framework we use with municipal clients across the Gulf, Africa, Southeast Asia and Latin America.
| Parameter | KT1D garbage compactor | KT3E road sweeper |
|---|---|---|
| Role | Waste collection & compaction | Street, kerbline & site sweeping |
| GVW | 18 t | 16–18 t |
| Battery (CATL LFP) | 200 kWh (232 kWh option) | 166 kWh (200 kWh option) |
| Traction motor (LvKong) | 282 kW peak | 282 kW peak / 150 kW rated |
| Working equipment | 14–18 m³ compactor body, e-PTO hydraulics, bin lifter | 2 side brushes, electric suction fan, 6–8 m³ hopper |
| Daily distance | 25–60 km | 15–40 km sweep + 20–50 km transfer |
| Shift energy draw | 130–170 kWh | 400–520 kWh (needs midday charge) |
| Noise at working speed | 68–72 dB(A) at 7 m | 66–70 dB(A) at 10 m |
| FOB price band | USD 95,000–125,000 | USD 85,000–115,000 |
The most important line in that table is the energy draw. The KT1D finishes a full shift on a single charge — its compaction work is intense but short-cycle. The KT3E cannot: its suction fan and brushes draw continuously for hours, so sweeping is one of the few EV truck duties where midday opportunity charging is a design requirement, not an option. That single difference drives most of the infrastructure and operational planning below.
A diesel compactor's engine runs the moment the crew clocks on — through bin lifts, pack strokes, crawls between stops and the trunk run to the transfer station. Our clients' telematics consistently show 65–75% of engine hours at idle or near-idle. The KT1D converts that waste stream directly: traction energy is metered to the metre, compaction energy to the stroke, and the truck is silent between stops. The operational gains are early-shift starts in noise-restricted zones and an annual fuel-plus-maintenance saving of roughly USD 22,500 per truck against diesel.
A diesel sweeper is worse, proportionally: nearly all its fuel goes to a fan and brushes, not wheels. The KT3E's variable-speed electric fan runs at 18 kW when the street is light and 45 kW only when it is not — an efficiency gain no diesel PTO architecture can copy. Annual energy-plus-maintenance savings run USD 18,800–21,000 per machine, and brush life extends from ~130 to ~250–300 hours because brush pressure is electronically regulated.
Here is the good news for directors who want both: the KT1D and KT3E share the CCS2 interface, the same telemetry platform and the same 18-tonne-class parts inventory. A sanitation depot electrifies cleanly with a mixed fleet:
The KT1D, in contrast, almost never needs midday energy. Its charge discipline is simpler: full overnight, unplug, run the route, replug. If your depot can only fund one charger in year one, the KT1D-first fleet sequence needs the least infrastructure to start.
| Metric | KT1D | KT3E |
|---|---|---|
| Purchase premium vs diesel | USD 25,000–45,000 | USD 25,000–35,000 |
| Annual operating advantage | ~USD 22,500 | ~USD 18,800–21,000 |
| Simple payback | 15–20 months | 15–20 months |
| 8-year lifetime advantage | USD 150,000–180,000 | USD 130,000–160,000 |
| Extra infrastructure per truck | Minimal (overnight AC) | Shared midday DC charger |
The economics are close enough that payback alone should not decide. The right split depends on what your city is being scored on: waste collection frequency and resident complaints (KT1D-led), or street cleanliness indices, air-quality dust limits and tender emissions clauses (KT3E-led).
For a department running, say, 40 sanitation vehicles on a two-year electrification budget, we usually recommend a 60/40 KT1D-to-KT3E first-wave ratio, adjusted by three tests:
Cities often ask where the KT3F and KT7A electric sprinklers fit. They are complementary rather than competing: sprinklers handle haul-road and stockyard dust suppression on high-cycle routes, where the KT7A's 232 kWh pack and 25 t GVW earn their keep at mines and ports. A fully electric sanitation department — KT1D collection, KT3E sweeping, KT3F/KT7A watering — runs on one charger ecosystem, one parts inventory and one training programme. That commonality is worth 10–15% in fleet overhead versus mixed-brand electrification, and it is the reason most of our municipal clients standardise on the full Dongfeng sanitation range in a single phased contract.
We quote KT1D and KT3E fleets together when clients phase delivery, which locks body specification, spares kits and training across both types and typically improves unit pricing by 3–5%. Both types ship with UN 38.3 and IMDG battery documentation, pre-shipment inspection of the working body, and a combined operator/technician handover — the same crews often rotate between machines, so joint training is standard practice. Right-hand drive is available on both for East/Southern Africa, Southeast Asia and Oceania markets. Lead time for a mixed order is 60–90 days from body-builder slot confirmation.
Consider a mid-sized city department running 30 sanitation vehicles that we recently modelled for a Latin American client. The diesel fleet burned 390,000 litres of fuel annually — 25,000 litres across the refuse compactor wing and 22,000 litres across the sweeping wing, the rest on watering and support vehicles. The phased electrification plan converted 10 KT1Ds in year one and 6 KT3Es in year two. Year-one results from the KT1D tranche: fuel down 96,000 litres (the compactor wing retired its worst offenders first), maintenance events down 41% on the converted units, and two noise-complaint investigations closed. Year two added the KT3E tranche with the midday charger and lifted the fleet's cumulative saving to roughly USD 400,000 per year against the diesel baseline. The department's finance office used those audited numbers to fund phase three — the sprinkler wing on KT3F/KT7A machines — entirely from operating savings, without a new capital request. That is the quiet power of the KT1D/KT3E pairing: each tranche generates the evidence and the cash for the next, and the depot, training and spares base built in phase one serves every truck that follows.
Can one charging depot really serve both truck types? Yes — the standard design is one 120 kW DC charger per three KT1Ds on the overnight layer plus one shared 120–240 kW charger for the KT3Es' midday windows; a 1 MVA depot connection covers a 20-truck mixed fleet comfortably with load management. And does the compactor or the sweeper degrade the battery faster? No — both run inside the CATL LFP envelope at under one equivalent full cycle per working day, which is why the 8-year/4,500-cycle warranty applies identically to both machines.
