For a 450mm GR module for lower-power air-handling assemblies, the GR45C-ZIK.DC.CR 116248/H01 gives engineers an exact ZIEHL-ABEGG part reference to carry into equipment selection and service work. In the Cpro range, the GR design is a ventilation module for integration into the customer casing; the family is built around a lightweight ZAmid impeller and seven backward-curved fluted blades. The listed configuration is a 450mm installation envelope, 3-phase 380-480V supply, 1800W input power and 1800RPM speed. The final selection still depends on the customer casing, duty point and control arrangement.

Selection Considerations
Select the module against the complete air path, including the customer casing and any filters or coils.
Match the customer casing opening, inlet geometry and outlet path before selecting the module.
Check whether the air feed is horizontal or vertical and preserve the intended rotation and discharge direction.
Use the official curve and project duty point to set the airflow and pressure target.
Allow for filters, coils, grilles and duct losses when reviewing the operating point.
Replacement Guidance
For service work, start with the complete installed reference and record the air-path orientation before removing the original module.
Record the exact GR45C-ZIK.DC.CR 116248/H01 reference and the 450mm installation envelope before disconnecting the original unit.
Confirm the inlet, outlet, rotation and air-feed direction against the equipment drawing.
Match the 3-phase 380-480V supply and the documented input and protection requirements.
Frequently Asked Questions
Q1: What is the Cpro GR design used for in the GR45C-ZIK.DC.CR 116248/H01?
A1: GR modules are intended for compact integration in customer applications with horizontal or vertical air feed, including industrial air-conditioning packages and clean-room air-handling sections where the project specification is met.
Q2: How should the GR45C-ZIK.DC.CR 116248/H01 be compared with the original fan?
A2: Match the 450mm installation envelope, mounting plane, inlet geometry, air-feed direction and electrical supply first, then compare the fan curve at the required duty point.
Q3: Does the listed noise figure for the GR45C-ZIK.DC.CR 116248/H01 equal the sound level in the machine?
A3: No. Where a noise value is listed, it is a product reference; casing, ductwork, operating point and installation position affect the final sound level.
Q4: What is the safest purchasing reference for the GR45C-ZIK.DC.CR 116248/H01?
A4: Use the complete model and article number shown for this page. Do not shorten an article-specific reference when requesting drawings or service documentation.
