Power: 22 kW · selected CWD22 examples · Pressure: 7 / 8 / 10 / 13 bar(g) · selected row · Flow: CWD22: 3.8 at 7 / 2.8 at 13 bar(g)

Crownwell's oil-injected catalog separates fixed-speed CWD, CWD PM and two-stage CWD-2S versions. At 22 kW, CWD22 lists FAD of 3.8 / 3.6 / 3.2 / 2.8 m³/min at 7 / 8 / 10 / 13 bar(g), dimensions 1,280 × 850 × 1,160 mm and 580 kg. CWD22 PM has the same listed four delivery entries but dimensions 1,120 × 850 × 1,160 mm and 520 kg. Keep the suffix on the offer and drawing.

CWD22-2S is a distinct 22 kW two-stage package listing 4.2 / 4.1 / 3.5 / 3.2 m³/min at the same four pressures, 1,480 × 850 × 1,180 mm and 820 kg. Motor power alone does not establish equal input, delivery or handling requirements. The manufacturer describes flexible-coupling direct drive, cooling and service-access features, with multiple-unit/base-load control among options. Confirm the actual supplied controls and operating range.

The stated performance basis is ISO 1217 Annex C, edition 4 (2009), at 1 bar absolute inlet, 20°C intake and 0% relative humidity. Agree current selected-model test/reference conditions and complete-package input. Provide logged demand, required pressure at users, distribution losses, shifts and backup requirements; compare proposals over that duty rather than adopting a universal savings claim.

Itemize electrical/cooling conditions, installation/service access, storage, drying, filters, drains and condensate treatment. Close the order with the model/serial drawing and test records, manuals, consumables, commissioning and destination support.
