Short Description:

1. Why Choose a Magnetic Levitation Chiller?

Traditional chillers rely on oil‑lubricated bearings, which introduce mechanical friction, oil migration issues, and regular maintenance needs.
NULITE’s magnetic levitation technology eliminates these pain points completely.

Key Benefits

• Oil‑Free Operation – No oil migration, no refrigerant contamination, no oil return concerns
• Zero Mechanical Friction – Magnetic bearings suspend the rotor in an electromagnetic field, achieving true contact‑free rotation
• Ultra‑High Efficiency – Combined with a variable frequency drive (VFD), the chiller precisely matches load demand, delivering exceptional full‑load and part‑load performance
• Lowest Maintenance – No oil changes, no filter replacements, drastically reduced downtime
• Quiet & Clean – Minimal vibration and noise, environmentally friendly

2. Core Technology & Components

The chiller integrates a magnetic bearing centrifugal compressor, evaporator, condenser, economizer, electronic expansion valve, onboard VFD, and an intelligent control system.

The compressor uses oil‑free magnetic bearings to achieve “0” friction operation. It features a high‑speed direct‑drive motor – no coupling, no gearbox, no mechanical bearings – delivering transmission efficiency close to 100%. Two‑stage compression further enhances performance.

3. Five Core Advantages

Additional Features

• Precise outlet temperature control – High‑precision sensors monitor in real time, ensuring minimal temperature fluctuation (±0.1 °C).
• Full‑condition adaptability – Perfect for HVAC, industrial process cooling, and other complex applications.
• Low noise operation – Magnetic levitation eliminates mechanical contact vibration. Extremely low noise, no additional soundproofing required.
• Environmentally friendly – Oil‑free design avoids refrigerant contamination, meeting modern environmental standards (RoHS, ErP).
• Stable and reliable operation – Soft start technology eliminates power grid surge, ensuring long‑term stability and enhanced system safety.

4. Installation Guide (Quick Start)

4.1 Before Installation

• Site: Indoor, ambient 5 °C ~ 40 °C, good ventilation. Clearance: ≥1.2 m around, ≥1.5 m above.
• Foundation: Level concrete (≤1/1000), capable of supporting operating weight.
• Electrical: Dedicated breaker, grounding, surge protector (Type 2).
• Water system: Install strainers (≥60 mesh), air vents, drain valves at evaporator/condenser connections.

4.2 Lifting & Placement

• Use provided lifting lugs. Sling angle ≤60°. Avoid hitting the control panel.
• Secure with anchor bolts or vibration pads. Recheck level.

4.3 Piping Connections

• Follow flow direction arrows. Install flexible connectors to isolate vibration (max working pressure 1.6 MPa, higher on request).
• Unit comes pre‑charged with refrigerant. No on‑site charging needed unless optional circuits are added (authorized personnel only).

4.4 Electrical Wiring

• Connect main power cable to the control cabinet via a dedicated breaker. Use correct cable gauge (see manual).
• Communication cables (RS485 / Ethernet): shielded twisted pair, run ≥300 mm away from power cables.
• No metal debris or tools left inside the control cabinet.

4.5 Pre‑commissioning Checks

• Verify all valves are in correct position (water valves open, refrigerant valves factory‑locked).
• Measure insulation resistance (≥5 MΩ). Check power phase sequence.
• Set target leaving water temperature, differential, start/stop times (factory defaults acceptable, fine‑tune per project).

4.6 First Start‑up

• Power on and preheat magnetic bearing controller for at least 24 hours (longer in cold ambient).
• Start water pumps and confirm flow (flow switch must activate).
• Press start on the control panel. Monitor: bearing levitation, rotation speed, current, inlet/outlet water temperatures.
• After 30 minutes of no alarms, complete the start‑up report.

4.7 Safety Instructions

• Strong magnetic field near the bearing controller during operation. Persons with pacemakers must stay ≥1 m away.
• Disconnect main power and wait 5 minutes (capacitor discharge) before any maintenance.
• Only certified refrigeration technicians are allowed to service the unit.
