Robertshaw ecl-35 Evaporator Low Temperature Limit Control

Product Description

The Robertshaw ecl-35 is an evaporator low temperature limit control designed for refrigeration and HVAC systems. It protects the evaporator coil from freezing by monitoring suction line temperatures and cutting power to the compressor when conditions become unsafe. HVAC technicians and refrigeration service pros rely on this type of control to prevent coil freeze-up, which can damage equipment and reduce system efficiency. The ecl-35 mounts directly to the suction line of the evaporator coil using its preformed clip, making installation straightforward and secure without extra hardware. Once attached, the device is wired in series with the Y connection to the compressor. Its normally closed contact opens when it senses that the evaporator coil is approaching freezing temperatures. When that happens, the contact interrupts the signal to the compressor, shutting it down before ice buildup can cause damage. This protects the compressor, the coil, and the refrigerant circuit from the stress of operating under frozen conditions. The ecl-35 is a passive, temperature-actuated device. It does not require a separate power supply or complex wiring. It works with the existing control circuit, making it compatible with a wide range of residential and light commercial refrigeration units, walk-in coolers, and air conditioning systems. Refrigeration technicians use low temperature limit controls like the ecl-35 to solve recurring freeze-up problems, improve system reliability, and reduce service callbacks. The clip-on suction line attachment means the sensor stays in direct contact with the line for accurate temperature detection. If you are servicing a system that keeps icing up, or replacing a failed low temp limit, the Robertshaw ecl-35 is a direct and dependable solution.

• Normally closed contact shuts down the refrigeration compressor when evaporator coil freeze-up is detected
• Preformed clip attaches securely to the evaporator suction line for fast, tool-free mounting
• Wires in series with the Y compressor connection for simple integration into existing control circuits

Product Highlights

The Robertshaw ecl-35 provides reliable freeze protection for evaporator coils by cutting compressor power the moment dangerously low suction line temperatures are detected. Its clip-on design and simple series wiring make it a practical choice for HVAC and refrigeration service work.
