Datasheet

Product overview

Power: CP22M 22 kW; CP75M / CP75DM 75 kW · Pressure: Published columns 0.7 / 0.8 / 1.0 / 1.3 MPa · Flow: At 0.8 MPa: CP75M 12.80; CP75DM 15.5 m³/min

Dehaha's CP product page publishes separate CPM single-stage and CPDM two-stage permanent-magnet variable-speed sheets. The single-stage sheet describes an integrated shaft arrangement, LCD display and PID pressure control. Its pressure columns are 0.7, 0.8, 1.0 and 1.3 MPa. CP22M lists 22 kW with 3.70 / 3.60 / 3.20 / 2.80 m³/min respectively, a G1 outlet, 1140 × 780 × 1210 mm dimensions and 370 kg mass. The original complete CP22M product image depicts that model, not the larger two-stage enclosure.

At 75 kW, single-stage CP75M lists 13.60 / 12.80 / 11.30 / 9.50 m³/min at those four pressures. Its installation data are G2 outlet, 1750 × 1272 × 1560 mm and 1120 kg. Two-stage CP75DM instead lists 16.0 / 15.5 / 12.8 / 10.2 m³/min, G2, 2100 × 1433 × 1590 mm and 1700 kg. At the same published 0.8 MPa duty, their flows are 12.80 and 15.5 m³/min. These are published selection points; they do not establish matched package input, full flow-reference conditions or actual annual savings.

The two-stage sheet separately gives CP55DM: 55 kW and 13.6 / 12.3 / 10.15 / 7.0 m³/min; CP90DM: 90 kW and 20.7 / 19.5 / 16.15 / 13.2; CP110DM: 110 kW and 24.8 / 24.0 / 20.2 / 15.21; CP132DM: 132 kW and 29.0 / 28.0 / 23.2 / 18.7, at the same pressure columns. The single-stage CP55M row prints 255 in its kW cell, so it is excluded from the motor examples rather than silently corrected. DHH75DM-8 in a historical energy-equipment catalogue is not automatically the same name as CP75DM.

State the selected stage arrangement and pressure, continuous/peak demand and operating hours. Obtain the full volume definition and pressure basis, minimum and maximum speed, part-load behavior and actual package input at your duty. Agree the supply voltage/frequency, ventilation and heat rejection, service access, receiver and dryer/filter scope, moisture/oil/particle targets, drains and destination documentation. Compare the offered machines with the same test boundary rather than using motor nameplate power or a generic saving percentage.
