Heaters

Featured products below are a small representation of the depth of the line.
Ramco Innovations is prepared to work with you configuring just the right solution for your process:

Watlow has developed a line of process air heaters that offer performance and versatility in medium to low-temperature applications. This rugged and reliable line of industrial heaters efficiently conducts heat.
Air heaters can be used to prevent freezing and condensation in electrical and mechanical housing or can be placed in ducts for forced-air heating.

Watlow's immersion heaters are designed primarily for direct immersion in liquids

Watlow's immersion heaters are designed primarily for direct immersion in liquids such as water, oils, solvents and process solutions.

These compact heating systems are ideal for fluid and gas applications such as purified and inert gases, supercritical fluids, and liquids like de-ionized water.

Fluid delivery heaters produce consistent results by reducing temperature and viscosity variations.

Flexible heaters from Watlow are thin, bendable, and shaped to fit almost any type of equipment.

Controllers


The ASPYRE Power Controller Family is flexible and scalable and available with a variety of options allowing one platform to be re-used across a wide range of applications, which can help save time and money. ASPYRE models available include sizes from 35 to 700 amps.

This power controller family features multiple advanced microprocessor-based firing and control mode algorithms. Combined with diagnostics and several communications options the product enables equipment and factory automation.

Controller firing modes include zero cross, burst firing, single cycle, delayed triggering, and phase angle. These smart algorithms enable the product to easily control a wide base of heater loads including Nichrome®, moly, silicon carbide, tungsten quartz, and infrared lamps, and transformer-coupled loads. ASPYRE offers a comprehensive list of modular options that deliver space and labor savings including controlled legs (1, 2, or 3), semiconductor fusing, load current measurement, amperage size, and user interface.

The WATCONNECT standard control panels are quickly configured to your specific application requirements and delivered expeditiously. WATCONNECT panels integrate Watlow’s high-quality heater, sensor, temperature controller and power controller products for a complete thermal solution. Normally, competitive custom panels require significantly longer lead times. The broad range of standard features allow customers to quickly configure panels that usually would be considered custom.

Watlow’s Sensors, Wire and Cable

A wide variety of temperature sensors including thermocouples, resistance temperature detectors (RTDs), wire, mineral insulated cable, connectors and hardware.

These sensors are suited for applications where accuracy and stability are essential for proper control in applications that operate at or below 1200°F (650C).

Thermocouples are best suited for high temperatures, extreme environments or applications requiring microscopic size sensors.

SERV-RITE® wire is used for connecting a sensor to an instrument or controller. Insulation temperature ranges from -328 to 2350°F (-200 to 1290°C).

Remote Access


The RMA PLUS Remote Access Module, an enhanced version of the legacy EZ-ZONE® RM remote access module. The RMA PLUS communicates quickly and efficiently and features an integrated USB connection that provides easy connection from a PC without the hassle of a converter.

The RMA PLUS offers plug-and-play access to the powerful EZ-ZONE RM family of controllers and integrates easily into existing systems. It comes standard with a built-in Ethernet switch eliminating the need to provide an additional switch for small systems. The RMA PLUS also offers port mirroring for troubleshooting and protects from broadcast and multicast storms. The integrated USB connection ensures real-time communication from software packages and the Modbus® TCP and Modbus® RTU capabilities allow users to connect to third-party and legacy devices.

The RMA PLUS is capable of data logging as well and users can log up to 16 gigabytes of data standard or upgrade to a user supplied 32 gigabyte SD card. Note, 32GB is the maximum size SD card allowed by design. Configuration and data logs are available as Windows® files so they can be easily accessed.
