5.3 Practical Retrofit Cases

Case1: Energy Saving Retrofit on Food Packaging Conveyor

Load: Biscuit packaging conveyor system

Before upgrade: Direct-on-line startup with heavy mechanical impact & high power waste

After upgrade: CIMR-AB4A0018FBA realizes soft start/stop & speed auto-adjustment following production cycle

Ergebnis: 30% longer equipment service life, 35% power reduction, 5% higher finished product rate

Case2: Central Air-conditioning Chilled Water Pump Retrofit

Load:5.5kW cooling circulation pump

Before upgrade: Constant-speed running with flow throttled by valve leading to huge energy loss

After upgrade: Inverter adjusts pump speed automatically based on return water temperature

Ergebnis: Approx.28,000 kWh annual power saving, payback period:6 Monate

6. Compliance bei Lufttransporten & Certification Manual

6.1 Air Transport Compliance Judgment

Built-in battery: No lithium cell equipped, only passive capacitors installed; excluded from UN3480/UN3481 lithium battery transport regulation

Shipping classification: General electrical goods, no UN38.3 test report or air identification certificate needed

Verpackung: Original factory carton or ISTA-certified packaging with anti-static & moisture-proof protection

6.2 Key Product Certifications

7. Auswahltipps & Kurzreferenzregeln

7.1 A1000 Selection Mnemonic

AB4A for three-phase 400V, capacity code links output ampere,

switch HD/ND duty freely, BA=with keypad, AA=without spare,

robust vector performance, fits most general industry drives.

7.2 Quick Calculation Rules

400V model prefix: CIMR-AB4A (with keypad) / CIMR-AA4A (keypad-less)

Ca. ND kW ≈ Capacity Code ×0.1; Ca. HD kW ≈ Capacity Code ×0.06

Code 0018 = HD5.5kW / ND7.5kW, rated output 17.5A

Detailed Field Application Breakdown

7. General Fluid Energy Saving (Fans & Pumps, prefer ND7.5kW rating)
8. HVAC Central Air Conditioning

Chilled water pumps, cooling tower fans, AHU supply fans

Funktionsprinzip: Variable speed regulated by water temperature & differential pressure instead of valve throttling; 30~50% power saved

Anwendung: Single pump ≤7.5kW for shopping malls, Bürogebäude & factory central air systems

2. Wasserversorgung & Drainage System

Plant service water pumps, booster pumps for secondary water supply, sewage & rainwater lift pumps

Constant pressure control: Closed-loop regulation with pressure transducer; low-speed running at night to cut idle loss

Suitable for residential pump rooms & small factory wastewater treatment stations

3. Boiler Auxiliary Equipment

Induced draft fan, forced draft fan & boiler feed pump with auto speed adjustment by furnace negative pressure.

5. Förderer & Bulk Material Handling (Constant-torque, select HD5.5kW)
6. Light Industry Assembly Conveyors

Food processing lines, carton packing conveyors, bottle filling & small roller bed lines

Vorteil: Soft start/stop prevents belt rupture; multi-speed switching matches production tact time

2. Small Mining & Aggregate Feeding Equipment

Light-duty belt feeders, spiral screw conveyors for grain, powder and sand transportation

Besonderheit: 150% low-frequency starting torque suits heavy inrush load at startup

3. Warehouse Sorting Equipment

Small sorting conveyors and pallet roller conveyors.

III. CNC & Machining Tools (High-precision speed control via vector drive)

1. Spindle drive for conventional lathe, bench milling & surface grinder: 0~400Hz wide frequency range enables stepless speed change to replace traditional gearbox and improve surface finish; ±0.2% speed accuracy for PG-less vector mode
2. Bench grinders, polishing machines & small wire drawing machines.
3. Textile Machinery (Primary constant tension control application)

Twisting frames, small looms, cone winding machines, fabric setting pull rollers

Nachfrage: Low-speed high torque & stable tension to avoid yarn breakage; A1000 vector drive perfectly matches 5.5kW rated load

1. Light Lifting & Hoisting Applications

Only for light-duty lifting; heavy crane uses H1000 series instead

Small cargo lifting platforms, fixed compact freight elevators, miniature electric hoists

Vorteil: Smooth start/stop prevents load slipping with zero-speed holding torque to eliminate mechanical impact

1. Rubber, Plastik & Verpackungsmaschinen
2. Auxiliary feed screw for plastic extruder & small pelletizer;
3. Horizontal flow wrappers, Siegelmaschinen & film winding machines with constant winding tension control.

VII. Grain & Feed Processing Equipment

Auxiliary drives for grinders, feed mixers, grain elevators and separator fans.

Prohibited & Unadvisable Installation Conditions

1. Explosion-prone chemical workshops: Standard IP20 design without explosion-proof certification; EX-type inverter required;
2. Altitude over 1000m: Minimum 10% power derating mandatory otherwise overheat alarm occurs;
3. Equipment with severe cyclic shock & Vibration (impact crushers, forging hammers): Loose terminals and PCB damage caused by continuous vibration;
4. Direct driving of large shock loads (heavy gantry cranes, large air compressors): Insufficient rated power, select high-power H1000 series;
5. Outdoor open-air mounting without control cabinet: No ingress protection; rain & dust damage internal power modules.

Verified On-site Application Cases

1. Fall 1: ND rated 7.5kW Chilled Water Pump

Injection molding plant pump retrofit: Original valve throttling at fixed speed; variable frequency control by coolant temperature saves around 26,000 kWh yearly.

2. Fall 2: HD rated 5.5kW Packaging Line Conveyor

Biscuit production main transport with frequent start-stop; full-load startup at 0.5Hz without slip; equipment failure rate cut by 70%.

Quick Selection Tip

Fans & Water Pumps → apply ND 7.5kW rating

Förderer, Werkzeugmaschinen, Textile Equipment → apply HD 5.5kW rating
