Eaton DILM Contactor for HVAC and Pump Control Systems
HVAC and pump control systems require reliable contactors for motor switching. RF Manda supplies DILM contactors compatible with Eaton Moeller for these applications.
HVAC System Applications
Chilled water systems:
- Primary chilled water pumps: DILM65-DILM150
- Secondary chilled water pumps: DILM40-DILM100
- Condenser water pumps: DILM80-DILM170
- Chiller compressor contactors: DILM100-DILM250
Boiler and Steam Systems
Boiler feed pumps:
- Small boiler feed: DILM25-DILM65
- Medium boiler feed: DILM80-DILM150
- Large boiler feed: DILM185-DILM400
Boiler feed pumps often use star-delta starters to reduce starting current.
Cooling Tower Applications
Cooling tower fans:
- Single-speed fans: DILM40-DILM100
- Two-speed fans: DILM65-DILM150 with reversing configuration
- Large cooling towers: DILM150-DILM250
Water Treatment Systems
Treatment plant pumps:
- Raw water intake pumps: DILM65-DILM150
- Filtration pumps: DILM40-DILM100
- Chemical dosing pumps: DILM17-DILM40
- Sludge pumps: DILM80-DILM170
Coil Voltage Selection for HVAC
Common HVAC control voltages:
- 24V AC: For electronic control systems
- 120V AC: For North American installations
- 220-240V AC: For European and most global installations
Typical Wiring Configuration
Standard HVAC pump starter wiring:
- Power supply L1, L2, L3 to contactor line side
- Motor connections T1, T2, T3 to contactor load side
- Control circuit through contactor coil (24V or 120V or 240V)
- Auxiliary contact for status feedback to BAS/BMS
Reliability Considerations
For HVAC applications, ensure:
- Contactor AC-3 rating above motor FLC
- Adequate enclosure ventilation
- Periodic coil and contact inspection
- Surge protection for coil (DILM-XSPR)
