In commercial kitchens, maintaining the right temperature is essential for food quality, presentation and efficient operation. Quartz and infrared heat lamps, as well as other suitable heating loads, require reliable power control to deliver consistent heat.
United Automation manufactures a range of commercial catering controllers and heated gantry dimmer switches designed for precise control of suitable heating loads in professional catering equipment.
The range includes QLC and QVR phase-angle regulators, with options for RFI suppression, high-surge applications, switched control, terminal-block connections and 110V or 230V systems.

A heated gantry dimmer switch controls the electrical power supplied to suitable quartz, infrared or other compatible heating loads. By regulating the AC power delivered to the load, it allows the operator to adjust the heat output to suit the application.
This type of power control is commonly used in:
For catering equipment manufacturers, a suitable power controller provides a practical way to integrate adjustable heat output control into equipment designs.
United Automation’s QLC and QVR controllers use phase-angle power regulation to control the AC power delivered to suitable loads.
Rather than simply switching a heating load fully on or fully off, phase-angle control allows the power output to be varied according to the position of the control.
On applicable QVR models, this provides 0–98% variable output control.
This makes phase-angle regulators suitable for applications where the operator needs to adjust heat output rather than rely on simple on/off control.
Depending on the model, United Automation’s catering controllers offer:
The exact features vary by product, so the individual product specification should be checked when selecting a controller.
The QLC range is designed for controlling quartz lamp heating systems and combines phase-angle power regulation with switched heat control.
These controllers are particularly suited to heated gantries, food warming systems, quartz heat lamps and commercial catering equipment where controlled heat output is required.
The QLC Standard is a 17A, 230V quartz lamp phase-angle regulator incorporating a 4-position switch potentiometer and Triac inrush protection.
It provides controlled power to suitable quartz lamp loads, allowing the operator to select the required heating level.
The QLC-RFI adds RFI suppression to the 17A, 230V controller, making it suitable for applications where electrical interference needs to be reduced.
The controller also provides a 4-position switched output and Triac inrush protection.
The QLC-HS is a 17A, 230V high-surge quartz lamp voltage regulator designed for applications where the load requires enhanced surge-handling capability. It provides switched phase-angle control for suitable quartz lamps and heating loads.

The QLC-TB-RFI range combines 15A phase-angle control, RFI suppression and terminal-block connections, with versions available for 110V and 230V systems.
The 230V version provides 0–98% variable output control with a 4-position switched output.
The QVR range provides variable AC power control for quartz lamps, heat lamps and other suitable heating loads.
Unlike a simple on/off controller, a QVR regulator allows the heating output to be adjusted continuously across its operating range.
The range is suitable for applications including heated gantries, quartz lamps, Bain-maries, hot food cupboards, ovens, moulders, dryers and other compatible heating equipment.
Available in 110V and 230V versions, the QVR Standard provides variable phase-angle control using a non-switched potentiometer.
The 230V version provides 0–98% variable output control and incorporates Triac inrush protection.
For applications requiring enhanced surge handling, the QVR High-Surge provides 17A, 230V variable phase-angle control with high-surge capability.
▷ View QVR High-Surge 17A 230V
The QVR-RFI combines variable phase-angle control with RFI suppression, providing adjustable power control for suitable quartz lamps, heat lamps and resistive heating loads.
For applications requiring both variable heat control and integrated switching, the QVR/S range combines phase-angle regulation with a switched potentiometer.
This makes the range particularly useful where the operator needs to switch the equipment and adjust the heat output using the same control.
Available configurations include:
The QVR/S-RFI provides variable phase-angle control, switching and RFI suppression in a 17A, 230V configuration.
It provides 0–98% variable output control for suitable quartz lamps and resistive loads.
The QVR/S-TB-RFI provides a 15A terminal-block configuration, with RFI suppression and switched variable control.
The 230V version provides 0–98% variable output control for suitable quartz lamps and other resistive loads.
