Eliwell EWPlus 961-HC Digital Temperature Controller for Commercial and Industrial Refrigeration Systems, 115V

The Eliwell EWPlus 961-HC is a professional-grade digital temperature controller built for industrial refrigeration systems. Operating on 115V with a 1 HP compressor relay, it uses a high-accuracy NTC probe to ensure precise temperature monitoring and control.

Engineered for durability, the controller supports 1 HP compressor loads at 120VAC, making it ideal for commercial coolers, freezers, and industrial refrigeration units. Its compact design features a clear digital display and an intuitive interface, simplifying temperature adjustments and system management.

The EWPlus 961-HC includes mounting hardware and wire connections for straightforward installation. Multiple terminal connections within a rugged industrial enclosure provide flexible control options for OEM applications and system upgrades.

✅ Pre-Programmed for Easy Installation

This controller comes pre-programmed and ready to install, reducing setup time and ensuring a smooth start-up (Plug-N-Play).

Compatible with standard NTC sensors, this Eliwell controller delivers consistent, reliable, and accurate temperature regulation across a wide range of cooling environments.

Applications

• Commercial Refrigeration: Walk-in coolers and freezers, beverage coolers in restaurants, bars, cafés, and supermarket display cabinets.
• Industrial Cooling Systems: Cold storage warehouses, food processing and packaging facilities, pharmaceutical storage (medications, vaccines).
• OEM Equipment: Ice machines, soft-serve machines, refrigerated vending machines, commercial refrigeration units in laboratories.
• HVAC and Environmental Control: Small-scale industrial HVAC systems, temperature-controlled test chambers, incubators, and greenhouse climate control (cooling sections).

System Types

• Compressor-Based Refrigeration Systems: Supports up to 1 HP compressor loads, ideal for small to medium commercial units; for compressors above 1 HP, an external power contactor can be used.
• Evaporator and Condenser Control Systems: Regulates temperature by switching compressors, fans, or defrost cycles.
• NTC Sensor-Based Temperature Loops: Compatible with standard NTC probes for accurate temperature monitoring.
• Digital Thermostat Integration: Easily retrofits existing systems or is installed in new OEM equipment for precise digital control.
