Hydrolevel Highlights Steam Pro Kit for Upgrading Mechanical Low Water Cut-Offs

Hydrolevel Company, a leading manufacturer of temperature and liquid level controls for residential and commercial heating applications, is proud to highlight its Steam Pro Kit, a low water cut-off kit designed specifically for steam boiler gauge glass attachments.

The Steam Pro Kit combines an advanced electronic low water cut-off with rugged components and installer-friendly features to deliver reliable protection, streamlined installations, and straightforward retrofits. The Steam Pro Kit features an electronic low water cut-off with a single probe design that provides reliable operation, reducing maintenance requirements and minimizing nuisance service calls for contractors and building owners. As a replacement for popular mechanical steam low water cut-offs, the Steam Pro Kit serves as a direct upgrade path for existing installations, making it easy for contractors to specify and install in place of legacy controls. Quick hook-up fittings speed up the installation process, helping installers reduce labor time and costs.

To support broad field use, the Steam Pro Kit adapts to all 8" to 14" sight glasses, delivering universal compatibility that eliminates the need to stock multiple models and simplifies inventory management. It uses Hydrolevel’s patented cast iron hub assembly for durable, long-lasting performance and overall system integrity in demanding steam environments, while an included wiring whip streamlines setup with simple, clear wiring that reduces installation time and minimizes errors. The Steam Pro Kit also incorporates indicator LEDs for visual status confirmation, enabling technicians to quickly troubleshoot and monitor operation without additional tools. Flush to test technology allows easy system verification so installers can confirm proper operation on site before leaving the job.

The kit is available in automatic reset versions, the 400 24V Cut-Off Kit and 450 120V Cut-Off Kit, providing convenience for applications where automatic operation is preferred and helping to reduce downtime after a low water event, while manual reset versions in the 500 24V Cut-Off Kit and 550 120V Cut-Off Kit offer a safety-focused option that requires manual intervention before the system restarts.

Installers can match the Steam Pro Kit to existing system requirements using these 24V and 120V models, providing flexibility without the need for additional transformers or power accessories. The automatic reset kit is designed to replace the McDonnell & Miller 67 series while the manual reset kit replaces the McDonnell & Miller 67M and the 67 series using an M switch. This enables easy retrofit of common existing installations and expanding market opportunities for contractors who service older steam systems, making the Steam Pro Kit a reliable, cost-effective solution for steam boiler low water cut-off protection.
