Protection and Control Solutions for HVAC Chillers

Products to keep your Chillers running smoothly…

Key product solutions for your HVAC applications offering both protection and control.

Protection

Relays for providing protection of compressors against faults which can occur either during installation or when in use.

• Power supply wiring errors – Prevents compressor from rotating in the wrong direction if phases are reversed
• Voltage stability issues – Protects compressors against overheating where voltage imbalance may occur
• Fuse failure – Protects against “single-phasing” if a phase is lost

PRODUCT Highlights

• Universal product with selectable nominal voltages for global applications
• Adjustable Restart Delay (up to 5 minutes) – Allows the powering up of multiple Chillers to be staggered therefore reducing the demand on the mains supply

PRODUCT Highlights

• Fixed voltage trip settings
• Adjustable Delay prevents compressor shutting down due to momentary voltage fluctuations

Safety

Ensures Chiller equipment (and personnel) are protected in the unlikely event of an Earth Leakage fault.

PRODUCT Highlights

• Adjustable trip and time delay settings
• Choice of toroid sizes to suit various power supply ampacities/Chiller sizes

Product Details

Control/Timing

Used to delay the starting of compressors but also suitable for random starting and and anti-short cycling operation.

PRODUCT Highlights

• Multi-voltage power supply – suits common 24VAC control voltage used in Chillers
• Adjustable time delay with wide range
