ZEL Zeta R600a compressor constructions

Compare the three start arrangements, not nine keyword pages

The actual source distinction is between HDZ, HPZ and HXZ motor/start groups. All three appear with nominal 100/125/140 identifiers, but their electrical codes differ. Ask ZEL to propose the exact start arrangement for the appliance and provide the model’s complete electrical application file.

Do not select by the number embedded in the model name or assume it is a guaranteed cooling rating. The source has performance columns, but lacks a complete rating basis and unit schedule. This page groups the related entries instead of creating nominal-output or voltage variants as separate search pages.

Resolve the frequency field before any order

The page lists 220–240, 115 and 100 V alternatives at family level while every model row’s frequency field is zero. Those statements do not identify a valid supply for any particular suffix. Ask the supplier to correct the table and name the permitted voltage/frequency and start components for the exact ordered variant.

The HXZ170A photograph does show 220–240 V and 50 Hz, but it is a different model from the nine rows. Its readable label cannot be used to fill their missing frequency data. Retain the discrepancy in the supplier enquiry instead of silently normalising the source.

Resolve the winding and start conflict between documents

The webpage’s nine rows label the winding Al and identify HPZ as CSCR. The manufacturer-linked catalogue’s physical page 11 instead labels the HPZ100A/125A/140A and additional HPZ versions Cu with RSCR. It also provides a broader range of HDZ and HXZ entries. These differences can reflect document versions or configurations, but no cause or current preferred revision was verified.

Request the ordered model/suffix and a current electrical/material schedule. Do not claim the entire platform uses aluminium winding or infer that a copper version has a proven lifetime advantage. Confirm the actual start components and qualification scope applicable to that configuration.

Keep source limits and photograph evidence bounded

The reviewed page states maximum shell temperature 95°C and maximum discharge temperature 120°C in addition to ambient, evaporation and pressure limits. These are upper-limit statements requiring exact-model confirmation, not a recommended operating condition or a simultaneous rated point. Obtain the manufacturer’s envelope and selected performance conditions.

The original HXZ170A image shows mounting feet, a terminal-side assembly, connections and nameplate markings. No full drawing or current issuer verification was reviewed. Visible approval symbols on that photographed unit do not certify the nine listed variants or establish their ordered connection dimensions.

The catalogue’s HXZ170A row gives 170 W cooling, 93 W input and COP 1.83 W/W, with Al winding, 9.2 cm³, RSCR, 4 µF, height 163 mm and mass 7.3 kg. Its static-cooling ASHRAE LBP conditions are −23.3°C evaporation, 54.4°C condensation and 32.2°C for suction, ambient and the source-labelled subcooling temperature. This gives a bounded document example for the pictured identifier, not verified current approval or appliance performance.

Close the corrected selection package

Ask for a current datasheet naming refrigerant, full suffix, electrical configuration, applicable envelope, all units and thermal test method. Require explanations for the asterisk and zero frequency cells and request the actual proposed unit’s outline/connection drawing. The performance columns can only support comparison after those missing conditions are resolved.

Record the start equipment and accessories included, appliance-validation scope, traceability and commercial terms. No current price, lead time or independently checked appliance performance was established. This source-specific Zeta brief helps resolve real catalogue issues rather than giving an unsupported efficiency score.
