Speed Queen Classic Line Industrial Tumble Dryers

The Speed Queen Classic Line is a range of heavy-duty industrial tumble dryers used in hotels, hospitals, mining camps, uniform rental operations, and commercial laundries across South Africa. Six models spanning 14 kg to 90 kg cover every throughput requirement from a boutique hotel linen room to a large-scale industrial laundry running continuous shifts. Every Classic Line speed queen tumble dryer features OPT Over-Dry Prevention Technology — monitoring 267 times more drum surface than conventional sensors — and is available with electric, gas, or steam heating to match the utility infrastructure already in place at your site. As authorised Speed Queen distributor since 1985, Unicorp supplies, installs, and supports the complete Classic Line range across South Africa.

The world’s most reliable industrial tumble dryers

Speed Queen is part of Alliance Laundry Systems — the world’s largest manufacturer of commercial laundry equipment — and has been building professional laundry machines for over 100 years. The Classic Line industrial tumble dryer range is built to the same engineering standard as Speed Queen’s washer-extractor range: tested to 10,400 cycles, with metal-component construction throughout and galvanised steel drums engineered for the corrosive, high-humidity environment of a working laundry. Micromaster 2 electronic controls on the SU055 and above provide programmable cycle management, multiple drying modes, and diagnostic capability that simplifies day-to-day operation and reduces the risk of operator error across multi-shift industrial tumble dryer South Africa installations.

Key benefits

• OPT Over-Dry Prevention Technology — 267× more sensing surface, maintenance-free: Speed Queen’s OPT system covers 267 times more drum surface area than conventional single-point moisture probes. Unlike brush-based sensing systems that require periodic replacement, Speed Queen’s OPT has no brushes and no wearing contact parts — it is entirely maintenance-free. This delivers consistent, accurate moisture measurement across every load, stopping the cycle precisely when linen is dry and eliminating the energy waste and fabric damage caused by over-drying.
• Micromaster 2 control with 30 programmable cycles (SU055–SU200): The Micromaster 2 electronic control system on all Classic Line models SU055 and above provides 30 fully programmable drying cycles, precise temperature management, and integrated diagnostics. Operators can configure dedicated programmes for different linen types — sheets, towels, workwear — and the system will replicate those settings consistently across every cycle with no manual adjustment required.
• Three drying modes — Time, Auto, and Moisture Dry: The Classic Line supports three distinct drying modes selectable per cycle. Time Dry runs for a fixed operator-set duration. Auto Dry combines time and temperature monitoring for consistent results with variable loads. Moisture Dry uses OPT sensing to end the cycle based on actual measured linen moisture, delivering the most energy-efficient drying outcome and the best protection against over-drying delicate fabrics.
• Step Dry — two-temperature drying for fabric protection: Step Dry is a programmable drying profile that applies high heat for the first half of the cycle — when heavy moisture load means heat is absorbed by evaporation rather than the fabric — then automatically reduces to a lower temperature for the second half as the linen approaches dryness. This protects fabric integrity while maintaining throughput speed, and is particularly valuable for hotel linen operations where linen longevity directly affects replacement costs.
• Galvanised steel drums for long-term corrosion resistance: Classic Line drums are manufactured from galvanised steel, providing durable corrosion protection in the permanently humid, chemically challenging environment of a commercial or industrial laundry. The drum geometry promotes even tumbling and balanced airflow distribution across the full load, contributing to consistent cycle-by-cycle drying results.
• Axial and/or radial airflow for maximum air utilisation: Depending on the model, Classic Line dryers use axial airflow, radial airflow, or a combination of both — optimising air circulation through the drum for maximum heat transfer efficiency and even drying across the load. Efficient airflow design reduces cycle time and heating energy per kilogram of laundry processed.
• Electric, gas, and steam heating across the full range: Every Classic Line model is available with electric, gas, or steam heating. Electric heating is the most common configuration for South African sites without an existing gas or steam supply. Gas variants offer faster heat-up and lower energy cost per cycle where natural gas or LPG is available. Steam heating is the most cost-efficient option for sites — typically hospitals and large hotel laundries — with an existing central steam boiler plant.
• 380V / 50Hz / three-phase electrical standard: All Classic Line models are configured for South African three-phase electrical supply — 380V / 50Hz — consistent with the standard industrial electrical infrastructure at hotels, hospitals, and commercial laundry facilities across South Africa.
• Large lint compartment and heavy-duty door hinge: The Classic Line lint filter compartment is designed for easy daily access and cleaning, reducing the maintenance time required between shifts. The heavy-duty door hinge construction withstands years of repetitive opening and closing in high-cycle industrial operation without developing looseness or misalignment.

Models and Specifications

The Speed Queen Classic Line spans six models from the 14 kg SU030 to the 90 kg SU200, providing a complete solution for every commercial and industrial laundry throughput requirement. All models are available with electric, gas, or steam heating; all operate on 380V / 50Hz / three-phase supply. The SU030 uses Dual Digital or Coin control for simpler self-service applications; the SU055 through SU200 use Micromaster 2 electronic controls with full programmability and diagnostics.

SU030 — 14 kg Entry-Level Industrial Tumble Dryer

The SU030 is the entry point to the Speed Queen Classic Line industrial range — compact in footprint (711 × 1191 × 1622 mm) but built to the same durability standard as the larger models. With a 271L drum, OPT moisture sensing, and either Dual Digital or Coin control, the SU030 is well suited to smaller hotel linen rooms, guest houses, bed and breakfast establishments, and self-service laundromat installations that need an industrial-grade dryer without the footprint or power requirement of a larger model. Available with 21 kW electric, gas, or steam heating on 380V / 50Hz / three-phase supply.

SU055 and SU075 — 23–34 kg Mid-Range Workhorses

The SU055 (23 kg / 530L) and SU075 (34 kg / 634L) are the most commonly specified Classic Line models for medium-volume hotel, hospital, and commercial laundry installations across South Africa. Both use Micromaster 2 electronic controls with 30 programmable cycles, three drying modes (Time, Auto, Moisture), and Step Dry capability. The SU055 and SU075 share the same height (1,946 mm) and similar width (981 mm), making them straightforward to pair side-by-side or with a Speed Queen SC Series or SY Series washer-extractor in a balanced-throughput laundry room layout. Available with 30 kW (SU055) or 36 kW (SU075) electric heating, or gas or steam variants.

SU120 — 55 kg High-Capacity Industrial Dryer

The SU120 steps into large-capacity industrial tumble dryer territory at 55 kg / 1,021L, suited to large hotel linen rooms processing 200 or more rooms’ worth of linen per day, hospital laundry departments, and commercial laundry operations running extended daily shifts. Micromaster 2 controls, OPT moisture sensing, and 60 kW electric heating (or gas or steam alternatives) make the SU120 a self-contained high-throughput drying solution. At 1,178 mm wide, 1,725 mm deep, and 2,177 mm tall, it requires careful site planning — Unicorp will confirm clearances, exhaust ducting requirements, and electrical supply specifications during the quotation and site assessment process.

SU170 and SU200 — 77–90 kg Maximum Capacity

The SU170 (77 kg / 1,408L) and SU200 (90 kg / 1,656L) are the largest models in the Classic Line range, designed for mining camp laundries, large industrial uniform rental operations, major hotel groups, and hospital linen services processing high daily volumes across multiple shifts. At this capacity tier, electric heating is not available — steam or gas heating is required, making these models most appropriate for sites with an existing steam boiler plant or reliable gas supply. Both models use Micromaster 2 controls and share the same 1,349 mm width and 2,388 mm height, differing in depth (1,749 mm vs 1,948 mm). Unicorp manages the full project — site assessment, utility coordination, delivery, installation, and commissioning — for SU170 and SU200 installations across South Africa.
