Little Giant EC-1U-DV Mini-Split Condensate Pump
Engineered for ductless mini-split systems, the EC-1U-DV is a compact, aesthetically pleasing condensate pump that operates automatically to remove condensate continuously. It supports dual voltage (110 or 240 V), offers a 4.9-foot cord with lead wires, and is designed to blend with modern indoor units while delivering dependable drainage in tight spaces.
Little Giant HT-VCL-30-P 208-230V Condensate Pump
Designed for high-temperature plenum applications, this 208-230V model handles the toughest commercial condensate removal tasks. It includes an internal float switch, an external test lever for quick verification, and safety wiring to connect to shut-down or alarms. The unit remains a robust choice for installations requiring reliable performance under demanding conditions.
Little Giant HT-VCL-60-P 208-230V Condensate Pump
The HT-VCL-60-P family provides high-temperature, 208-230V operation with a 62-foot shutoff capability for extended drainage runs. Automatic operation is driven by a built-in float switch, and the external test lever ensures quick checks of pump functionality without tank filling. Safety wiring is included to support reliable integration with HVAC control systems in large commercial spaces.
Buying Guide: Key Purchase Considerations
- Voltage and horsepower: Match the pump’s voltage to your power supply and consider horsepower based on the condensate load and run length.
- Plenum suitability: If installed in air handling spaces, ensure UL 2043 or equivalent listings for safe use in plenums.
- Auto operation and testing: Look for built-in float switches and external test levers to simplify maintenance and verification.
- Safety wiring: Verify that safety wiring is included to shut down equipment or trigger alarms as needed.
- Inlet size and installation space: Check inlet diameters and overall dimensions to fit tight spaces or custom plumbing.
- Voltage adaptability: Some models offer dual voltage options or 110/240 V compatibility for flexibility in various facilities.
- Certifications: cCSAus or UL listings add assurance for commercial and regulated environments.
- Noise and mounting: Consider rubber feet and compact form factors to minimize vibration and noise in occupied spaces.
