Speed Queen SC Series Medium Speed Washer-Extractors
Commercial-grade hardmount washers for hotels, hospitals, and on-premise laundries — 9 kg to 36 kg capacity
The Speed Queen SC Series is the benchmark hardmount speed queen washer extractor for commercial laundry operations requiring proven durability, straightforward installation, and predictable long-term performance. Built on a welded steel A-Frame chassis and tested to Speed Queen’s 10,400 cycle standard, the SC Series is available from 9 kg (SC20) through 36 kg (SC80) with Quantum Gold Gamma control, 200G medium speed extraction, and an inverter drive motor — establishing it as the standard industrial washing machine South Africa hotels, hospitals, laundromats, and on-premise laundries rely on for multi-shift daily throughput. Unicorp supplies and supports the full SC Series range as authorised Speed Queen distributor since 1985.
Hardmount precision for commercial laundry operations
The SC Series hardmount design — bolted directly to a concrete floor slab — eliminates the internal vibration management complexity of softmount machines, making it the simpler and more cost-effective installation choice for most South African commercial laundry environments where a concrete floor is already in place. The welded steel A-Frame chassis provides structural rigidity that maintains drum alignment and extraction geometry over years of daily multi-shift operation without fatigue or loosening. Quantum Gold Gamma control with 30 fully programmable cycles provides precise wash parameter management across different linen types and soil levels, while the inverter drive motor reduces energy consumption by up to 33% compared to fixed-speed equivalents. Water Guardian leak detection, stainless steel inner and outer tubs, and both 230V and 380V electrical configurations across the range make the SC Series a durable, efficient, and electrically flexible commercial washer-extractor for South African laundry operators at every scale.
Key benefits
- Welded steel A-Frame chassis for structural rigidity: The SC Series is built around a fully welded steel A-Frame — not a bolted frame assembly. Welded construction eliminates the joint fatigue and frame loosening that occurs in bolted chassis designs after years of high-speed extraction cycling, maintaining drum alignment, bearing geometry, and extraction performance across the machine’s full working life.
- 200G medium speed extraction: The SC Series extracts at up to 200G, removing a significant proportion of residual moisture from linen before it reaches the dryer. Higher extraction G-force directly reduces tumble dryer cycle time and energy consumption per kilogram of laundry processed — making the SC Series a cost-efficient choice for on-premise laundries balancing washing and drying throughput.
- Quantum Gold Gamma control — 30 programmable cycles: The Quantum Gold Gamma control system provides 30 fully user-programmable wash cycles with precise temperature, spin speed, water level, and cycle time parameters. Operators configure dedicated programmes for sheets, towels, workwear, delicates, and other fabric categories — and the system replicates those parameters consistently every cycle, eliminating manual adjustment and reducing operator-dependent variation in wash quality.
- Inverter drive motor — up to 33% electrical savings: The SC Series inverter drive motor continuously adjusts speed and torque output to match the actual load condition throughout the wash cycle, reducing electrical energy draw during low-demand phases. Compared to fixed-speed AC motors, inverter drive technology reduces total cycle electrical consumption by up to 33% — a meaningful operating cost reduction across the daily cycle counts of a commercial laundry.
- Water Guardian leak detection: Water Guardian continuously monitors water fill levels during the wash cycle and automatically shuts the machine down if an abnormal fill condition is detected, preventing flood damage to the laundry room. This protection is standard on the SC Series and is particularly important in hotel upper-floor laundry installations, hospital laundry departments, and any location where a water leak would cause structural or operational damage.
- Stainless steel inner and outer tubs: Both the inner drum and the outer tub on the SC Series are manufactured from stainless steel, providing corrosion resistance in the permanently humid, chemically aggressive environment of a commercial laundry. Stainless steel construction extends the working life of both components significantly compared to plastic or coated steel alternatives.
- Six capacity options from 9 kg to 36 kg: The SC Series spans six models — SC20 (9 kg), SC30 (13 kg), SC40 (18 kg), SC60 (23 kg), SC65 (27 kg), and SC80 (36 kg) — allowing Unicorp to specify the exact capacity that matches your daily linen throughput without over- or under-sizing the equipment for your operation.
- 230V and 380V electrical configurations: The SC Series is available across South African electrical supply configurations — 230V / 50Hz single-phase for smaller models suited to lighter commercial environments, and 380V / 50Hz three-phase for the larger industrial-grade models — ensuring every model can be connected to the existing electrical infrastructure at your site without upgrade work.
- Hardmount installation simplicity: Unlike softmount machines, hardmount washer-extractors do not require internal vibration suspension systems or the additional engineering assessment those systems require. Bolting the SC Series to an existing concrete slab is a straightforward installation that Unicorp manages end-to-end — including anchor bolt specification, electrical connection, and commissioning.

SC20 and SC30 — 9 kg and 13 kg
The SC20 (9 kg) and SC30 (13 kg) are the entry models in the SC Series, running on 230V / 50Hz single-phase supply — the standard electrical connection available at most South African commercial premises without three-phase infrastructure. They are well suited to small hotels and guest houses, salons, small on-premise laundries, and laundromats with limited electrical supply capacity. Despite their smaller capacity, both models carry the full SC Series A-Frame construction, 200G extraction, and Quantum Gold Gamma control — delivering commercial-grade performance at a footprint and electrical load appropriate for light commercial environments.
SC40 and SC60 — 18 kg and 23 kg
The SC40 (18 kg) and SC60 (23 kg) are the workhorse models of the SC Series — the most commonly specified Speed Queen hardmount washer-extractors for medium-volume hotel laundry rooms, hospital laundry departments, and commercial on-premise laundries across South Africa. Both require 380V / 50Hz three-phase supply and deliver 200G extraction with Quantum Gold Gamma control and 30 programmable cycles. The SC40 and SC60 are typically paired with Speed Queen Classic Line SU055 or SU075 industrial tumble dryers in balanced-throughput laundry room layouts.
SC65 and SC80 — 27 kg and 36 kg
The SC65 (27 kg) and SC80 (36 kg) are the largest hardmount models in the SC Series, designed for large hotel linen rooms, mining camp laundries, hospital linen services, and industrial uniform rental operations processing high daily linen volumes across continuous-shift operation. The SC80’s 36 kg capacity is the highest available in the hardmount tier of the SC Series. Both models require 380V / 50Hz three-phase supply and are typically paired with Speed Queen Classic Line SU120 or larger industrial tumble dryers to maintain balanced washing and drying throughput. Unicorp manages the full installation project — site assessment, concrete anchor specification, electrical connection, commissioning, and operator training — for SC65 and SC80 installations across South Africa.

Frequently Asked Questions
The Speed Queen SC Series is a range of hardmount medium speed washer-extractors designed for commercial and industrial laundry operations that need reliable, continuous daily throughput. It is the standard Speed Queen washer-extractor for hotels, hospitals, guest houses, laundromats, nursing homes, and on-premise laundries across South Africa — available in six capacity sizes from 9 kg (SC20) to 36 kg (SC80), covering operations from a small guest house to a large hospital linen service. Unicorp supplies and supports the full SC Series range as authorised Speed Queen distributor.
The SC Series is a hardmount washer-extractor — it bolts to the floor and extracts at up to 200G. The SY Series is a softmount washer-extractor — it uses an internal vibration suspension system, requires no floor anchoring, and extracts at up to 400G. The SY Series removes more residual moisture per cycle, reducing drying time and energy cost, but requires a more involved site assessment and typically a higher capital investment. The SC Series is the more straightforward installation and is the right choice for most South African commercial laundry environments where a concrete floor is available and 200G extraction meets throughput requirements.
The right SC Series model for a hotel laundry depends on room count, linen types, and daily shift patterns. Small hotels and guest houses processing up to 30–40 rooms typically suit the SC20 or SC30. Mid-size hotels in the 50–100 room range usually specify the SC40 or SC60. Larger properties with over 100 rooms, or those processing heavy towelling volumes across multiple shifts, typically require the SC65 or SC80 — or multiple machines in parallel. Unicorp will specify the correct model configuration for your property during the quotation and site assessment process.
The SC20 and SC30 run on 230V / 50Hz single-phase — the standard South African commercial electrical supply available at most premises without an electrical upgrade. The SC40, SC60, SC65, and SC80 require 380V / 50Hz three-phase supply, which is the standard industrial electrical supply at most hotel, hospital, and commercial laundry facilities. If you are unsure about your site electrical supply, Unicorp will confirm the requirements and advise on any electrical work needed during the site assessment process.
Yes. The Speed Queen SC Series is widely used in South African laundromats, typically in the SC20 and SC30 capacity range for self-service customer use, and SC40 or SC60 for attended vended laundries or drop-off laundry services. The Quantum Gold Gamma control system supports coin and cashless vend configurations via LaundryConnect, and the machines’ 10,400 cycle durability standard makes them the practical long-term choice for laundromat owners who cannot afford frequent machine replacement or extended downtime. Unicorp can advise on the most appropriate configuration for your laundromat layout and customer base.
