Designed for contractors and trades professionals working in utilities, construction, confined space, and industrial environments, this unit is UL Listed and CSA Approved for safe, reliable operation. It runs on standard 120V, 60 Hz power and features an easy-to-adjust thermostat for precise temperature control.

Technical Specifications

Available Items

Unlike open-element portable heaters, the Allegro 9401-50 features fully enclosed heating elements and a sealed motor, reducing exposure risk in dusty or debris-laden job site environments. Its all-steel rigid housing provides durability that plastic-bodied consumer heaters cannot match, making it a purpose-built solution for demanding construction and industrial applications.

Key Features & Benefits

All-Steel Rigid Metal Housing

The rugged all-steel construction withstands the physical demands of active job sites, including impacts, vibration, and rough handling. This heavy-duty design ensures the heater holds up through repeated use across multiple projects.

1500 Watts / 5,000 BTU Heating Power

Delivers enough heat output to raise the air temperature inside an Allegro work tent by approximately 50°F (10°C), significantly improving worker comfort and productivity in cold conditions. The 115 CFM airflow ensures heat is distributed efficiently throughout the enclosed space.

Easy-to-Adjust Thermostat

The user-friendly thermostat knob allows workers to dial in temperatures between 32°F and 100°F (0°C to 37.7°C) without tools or complex controls. This range gives contractors precise control over the work environment regardless of outdoor conditions.

Overheat Protection

Built-in overheat protection automatically safeguards the unit during extended operation, reducing the risk of equipment damage or fire hazard on the job site. This feature supports safe, unattended use during work shifts.

High-Quality Sealed Motor

The sealed motor design keeps out dust, debris, and moisture that are common on construction and industrial sites, extending the service life of the unit. A reliable motor means fewer breakdowns and less downtime.

UL Listed & CSA Approved

Third-party safety certifications from UL and CSA confirm the heater meets established electrical safety standards, which is often required for use on regulated job sites and in confined space applications. These certifications give contractors and safety officers confidence in the unit's compliance.

Lightweight & Portable

Despite its heavy-duty steel construction, the heater is designed to be lightweight and easy to transport between work areas or job sites. Portability reduces setup time and allows the unit to be repositioned as work progresses.
