Dehaha CP PM VSD screw and DCO oil-free scroll, Qidong

Dehaha / DHH is the English face of Dehaha Compressor Jiangsu Co., Ltd. The official site describes a company focused on industrial air-compressor research and manufacture, and it names oil-free water-lubricated, oil-cooled permanent-magnet VSD and two-stage screw as the energy-saving story. Homepage figures claim 27 years of brand history, coverage in 12 provinces, 170 outlets and shipments to 29 countries. The contact block gives Xiyuan Road 1199, Qidong Economic Development Zone, as Jiangsu headquarters and a Jing\'an office on Gonghexin Road, Shanghai. Those sentences are the public file.

The product centre that matters here is wider than two rows. Tiles and menus name CP-series PM VSD screw, centrifugal air, water-lubricated oil-free screw, other PM VSD frames, laser-cutting specials, dry oil-free, oil-free scroll, oil-free screw blowers and aftertreatment (adsorption dryers, refrigerated dryers, receivers). Only DHH-CP and DHH-DCO are catalogue SKUs on this desk. Water-lubricated oil-free, laser packages, centrifugals and blowers stay on the official nav.

CP is an oil-injected permanent-magnet VSD package: one-shaft direct-drive language, large host / low speed, and a variable-speed story sit on the homepage. DCO is oil-free scroll. The official DCO page describes orbiting-scroll compression, no oil in the process, few wearing parts, digital / staged control and a small replaceable host (the page mentions a host weight of about 20 kg). It names medical, food and electronics as clean-air uses. Scroll is not a substitute for a 160 kW two-stage plant compressor. Do not send a factory-hall FAD and expect a DCO price.

kW, bar and FAD stay on the quotation. The fetched CP and DCO pages did not give this desk a complete English performance table to copy. Voltage, frequency and whether a dryer belongs on the skid are buyer data.

No ISO 8573 class, CE or ASME stamp is printed here. The homepage quality block talks about German, European and Chinese national standards without naming a certificate number this desk will invent.

The homepage also tiles a centrifugal air compressor and a water-lubricated oil-free screw. The water-lubricated page says water replaces oil, names food and pharma as uses, and describes two screw stages. That is a third architecture. Keep it off the CP packing list and off the DCO scroll row. If that is the duty, write water-lubricated in the remarks.

Laser-cutting specials and aftertreatment (adsorption dryer, refrigerated dryer, receiver) are likewise official nav items. A laser package needs cutter pressure. A dryer needs a dew point. Neither is an extra compressor SKU here. Twenty-seven years, twelve provinces and 29 countries are homepage scale claims. They help a buyer see an export-capable OEM. They do not set a lead time or a CE number. Write the destination standard on the RFQ if the machine must land with a named paper.

Two-stage screw language on the homepage energy-saving block is a design claim, not a third catalogue SKU. If the buyer wants two-stage oil-injected rather than CP single-stage VSD, write two-stage in the remarks and keep it off the DCO scroll row. 5S production language on the homepage is a shop slogan. It is not a certificate. Ask for the paper the destination market actually requires. The plant in Qidong remains the seller. Dehaha quotes.
