The Caloritech™ CPA Fully Packaged Control Panel is suitable for use in a variety of electric heater installations – please consult with your Caloritech™ rep for details.

The Caloritech™ CPB Basic Control Panel is used to interface with electric heaters that have remotely located thermostats, limit controls, percentage timers or other control components. Please note that this model does not include a disconnect switch.

The Caloritech™ CPG Ground Fault Protection Control Panel is specifically designed to provide ground fault protection of permanently installed commercial and industrial heating equipment such as infrared radiant heaters, and to protect the heating equipment from damage due to excessive leakage currents. It is not suitable to provide shock protection. A factory wired ground fault sensor continually monitors the circuit for harmful leakage currents and opens the circuit when a threshold value has been reached. The wide 10mA to 100mA adjustable setpoint of the ground fault sensor provides protection of single or multiple heaters. This unit is for use in conjunction with other devices providing main circuit isolation, overcurrent or short circuit protection.

The Caloritech™ CPP Power Pack Control Panel consists of a prewired contactor, transformer, pilot light and fuses in a Type 4 enclosure for a quick and convenient installation. Control circuits are 120 VAC. Panels can be built to meet weather resistant or hazardous location specifications. Check factory for details.

The Caloritech™ CPS Control Panel (Contactor Stages) is ideal in scenarios where more than two levels of staging are required. The CPS series includes a modulating temperature control driving a step control, which in turn brings on a number of contactor stages. Time delay between steps is adjustable to match the system dynamics. The high limit is a 543 manual reset, with thermocouple for -20°C to 1100°C (-4°F to 2012°F) range.

The Caloritech™ CPXD Control Panel is normally supplied with the XDF Explosion-Proof Duct Heater. These control panels are available in two basic types – type 4 moisture-resistant or explosion proof, and with four different control packages (see Catalog for details). All CPXD control panels are supplied with magnetic contactor, HRC fusing, fused 120V control transformer, high limit controls, control circuit, ON/OFF switch, control ON light, high limit indicator light, high limit push-to-reset, terminals for connection of temperature controls and differential air pressure switch.

Caloritech™ Solid State Power Control Panels come in two different series. CPSS Series The Caloritech™ CPSS Solid State Power Control Panel with Base Load uses a combination of contactor stages controlled by a step control and an SCR solid state power control for fine tuning. Typically the SCR stage switches 20 to 30% of the total load with contactors making up the balance. The control package automatically determines when extra base load contactor steps need to be brought in or dropped out. Many adjustments such as proportioning band, zero and span, and time delay between stages are field adjustable to fine tune to the process. CPE Series The Caloritech™ CPE Full Solid State Power Control Panel is designed for automatic control of electric heaters using proven concepts and procedures. All Caloritech™ control panels can be custom built to meet various environmental requirements including dust, oil, and water, as well as corrosive or hazardous materials. The CPE unit features full SCR control. Multiple backup contactors are used to protect and facilitate wiring to the process heater. Where necessary, Type 12 enclosures include fans and vents to keep ambient temperatures to a safe level.
