SLTT two-stage PM variable-speed screw compressors — Sollant Machinery (Linyi works)

Datasheet

Product overview

Power: 22 kW · SLTT-22V example · Pressure: 8 / 10 / 13 bar versions · Flow: 2.00–4.55 m³/min at 8 bar · SLTT-22V

Sollant's SLTT range combines two-stage oil-injected screw compression with permanent-magnet variable-speed drive. The product description identifies oil injection for cooling between stages. It is an oil-injected route; two stages and a PM motor do not make the resulting air an oil-free classification.

The original specification graphic gives SLTT-22V as 22 kW with capacity ranges 2.00–4.55 m³/min at 8 bar, 1.72–3.83 at 10 bar and 1.36–3.04 at 13 bar. The row lists 732 kg, DN40 and 1,610 × 1,050 × 1,380 mm. Keep the working pressure attached to the flow range and obtain the offered reference/test conditions and package input.

SLTT-75V is a separate 75 kW selection. The corresponding ranges are 7.56–16.80 at 8 bar, 6.30–13.99 at 10 bar and 5.53–12.30 at 13 bar. Its listed mass is 2,100 kg and outlet DN50. Length 2,285 mm and height 1,800 mm remain listed, while width changes from 1,500 mm at 8/10 bar to 1,685 mm at 13 bar. Approve the pressure-specific drawing before planning access and handling.

Send normal, peak and minimum demand by shift, supply, ambient and user air-quality requirements. Ask how the offered controller handles demand below the published range and sequencing with other machines. Itemize treatment, receiver, drainage, inspection records and maintenance access. Compare energy at matched operating conditions rather than treating advertised savings as guaranteed for every plant.
