Dehaha DCO modular oil-free scroll — 8 bar duty and module counts — Dehaha / DHH Compressor (Qidong)

Datasheet

Product overview

Power: Selected table 3–44 kW; model numbers differ · Pressure: 8 bar — published table · Flow: 0.35–5.20 m³/min at 8 bar — separate models

Dehaha's DCO range combines fixed and orbiting scroll elements; its actual compression diagram shows gas pockets shrinking toward the central discharge. Larger machines combine several scroll modules with staged control. The detailed scroll material is used here rather than the page's generic opening sentence about two rotating screws, which describes a different architecture.

The table lists every selected duty at 8 bar. DCO4-8 is 3 kW with one 3 kW module and 0.35 m³/min. DCO15-8 is 11 kW with two 5.5 kW modules and 1.30 m³/min; DCO20-8 is 15 kW with five 3 kW modules and 1.75; DCO30-8 is 22 kW with four 5.5 kW modules and 2.60; DCO60-8 is 44 kW with eight 5.5 kW modules and 5.20. The model number is not the package motor rating, and the full flow reference and pressure basis must accompany the offered duty sheet.

DCO15-8 lists G3/4 outlet, 1670 × 680 × 1698 mm and 360 kg, while DCO20-8 lists G1, 1370 × 860 × 1308 mm and 550 kg. DCO60-8 lists G1-1/2, 1670 × 860 × 2298 mm and 700 kg. These are enclosure dimensions, not service or module-removal clearances. The published noise column lacks test distance and measurement conditions, so it is not used as a guaranteed room-noise value. The original family illustration shows complete cabinet and open module arrangements without identifying every table row.

Give the base and peak load, whether interruption during service is acceptable, and the process air specification. Ask how modules start/stop, rotate operating hours and respond to a failed or isolated module, and obtain available output under the intended maintenance condition. Do not assume that removing one module leaves certified proportional package flow. Agree supply voltage/frequency, ambient and cooling limits, cabinet access, wear-part intervals and controller safeguards. Define dryer/filters, drains, purity sampling and acceptance tests; an oil-free compression method alone does not establish food, medical or breathing-air compliance. Request drawings, inspection records, destination documents, manuals and commissioning/support responsibilities.
