MXS – Gain and Gate Guide Heater

The Caloritech™ MXS Gain and Gate Guide Heaters are specifically designed to prevent ice build-up on sluice gate guides or bodies. The heater is usually installed in a vertical well or duct of round or square cross section having a round nozzle at the top for fastening. Heating elements are silver brazed into a water tight terminal housing having recessed base for mounting. Unlike open wire heaters with ceramic supports, MXS heaters can be coiled to a six foot diameter to facilitate shipping and handling.

CXF – Flange Heater (Incoloy® Sheath, Low/Medium Density) Suitable for heating oils, gases & mild corrosives

Caloritech™ CXF Flange Heaters are used primarily for heating applications involving oils, gases and mildly corrosive liquids. They are constructed of incoloy® sheathed elements silver brazed to a steel flange, similar to the CXI Flange Heater. However, the CXF model is lower density and more suitable for stagnant or heavy oils, or for high temperature, low flow gas heating.

Unit Heaters

Our electric space heaters are designed and manufactured to comply with the most stringent requirements in a nuclear power plant installation. CCI Thermal Technologies has a standard and custom line of products that support space heating requirements for environmental or process heating. Unit heaters have a specify application in environmental room temperature control.

Duct Heaters

Duct heaters are specifically designed to match the customer specifications and they are qualified and tested to meet the most demanding requirements. Duct heaters are commonly used to heat air and/or gas process streams in process heating or environmental room applications. Applications include: humidity control, machinery pre-heating, HVAC comfort heating.

Circulation Heaters

Circulation heaters are the equivalent to tube and shell heat exchangers with the particular feature that the core bundle is manufactured with electric tubular heating elements. Circulation heaters are used in applications where a process stream needs to be heated to a finely controlled set-point. Typical applications include: air/gas superheating, oil pre-heating, steam superheating, fuel pre-heating and others. Circulation heaters are designed and manufactured in accordance with ASME Section III, Class 1, 2 or 3 and stamped N according to code requirements. Immersion heaters also are designed and manufactured under ASME Section VIII, Div 1 for non nuclear code applications.

Immersion Heaters

Electric immersion heaters are commonly used in tank and pressure vessel heating applications, where there is a requirement to maintain liquid temperature to a certain controlled set point. Typical applications include: antifreeze protection on refueling water storage tanks, oil tanks, fuel-oil tanks, diesel tanks, water tanks, vaporizing vessels and others. Immersion heaters are designed and manufactured in accordance with ASME Section III, Class 1, 2 or 3 and stamped NPT according to code requirements. Immersion heaters also are designed and manufactured under ASME Section VIII, Div. 1 for non nuclear code applications.

Pressurizer Heaters

Electric pressurizer heaters are used to control the pressure in the pressurizer vessel of PWR and PHWR reactors. These heaters are directly installed in the pressurizer vessel and they are electrically powered to provide the heat input required to maintain pressure control during transient conditions. The pressurizer heaters are designed and manufactured in accordance with ASME Section III, Class 1 and stamped NPT according to Code requirements.

HX – Straight Unfinned Tubular Heater (Calrod® type*)

The Caloritech™ HX Straight Unfinned Tubular Heater (Calrod® type*) can be used in most heating applications that require process heating temperatures up to 750°C (1382°F). These tubular elements can be clamped, immersed, cast into metal or spaced away from the work as radiant heaters. They can also be positioned in ducts or vessels for heating air and other gases. All Caloritech™ tubular heater styles offer a selection of sheath diameters and material options, including copper, steel, stainless steel and incoloy®.

KX – Finned Tubular Heater (Calrod® type*)

The Caloritech™ KX Finned Tubular Heater (Calrod® type*) is typically manufactured to custom specifications based on the customer application, where steel fins are spirally wound over a heating element and then metallurgically bonded by furnace brazing, leaving negligable thermal resistance at the joint. They are normally used for forced convection heating applications with outlet air temperatures up to 300°C (572°F), such as forced circulation, air or gas heating systems like ducts, fan forced electric heaters, recirculating ovens and loading resistors. Finned tubular heaters offer distinct advantages over open coil heaters, including minimized risk of fire or electrical shock, longer service life and less overall required maintenance.

MC – Cast-In Immersion Heater

The Caloritech™ MC Cast-In Immersion Heater is used for melting soft metals such as solder, tin, lead and babbitt at temperatures up to 510°C (950°F). The standard units are available in three styles to accommodate a range of installations: over-the-side, through-the-bottom and through-the-side. Custom designed units are also available for specialized applications, such as non-standard single phase and three phase metal melting heaters, heating plates, heat storage systems and corrosive fluid heaters. Large diameter, heavy wall steel element, Iron casting, General purpose terminal box, Rated up to 3 kW at 120V and 10 kW at 240V; two 240V heaters rated 2 kW and above can be connected in series to a 480 volt supply, Watt densities available at 30 W/in2, 14 W/in2 and 20 W/in2 (through-the-bottom model only), The through-the-side and through-the-bottom models supplied with a non-asbestos, high temperature gasket.
