Circulation heaters are the perfect solution for generating heat and enhancing normal immersion heaters performance. They are designed to heat pressurized circulating fluids and to provide effective, controlled heating to water, oil, steam and other gases. Circulation heaters are composed of all-in-one units with a heater mounted inside an insulated tank. They are made of a flanged or a screw plug immersion heater that is inserted into a pressure vessel or a pipe body. Heaters have inlet and outlet piping where the liquid or gas goes through the tank in order to reach the desired temperature.KEY FEATURES
- Standard sizes: 1.25” NPT screw plug size to 14” diameter
- Steel vessels fitted with 150 lb. flanges
- Thermal insulated vessels
- Custom unit sizes: up to 44” nominal pipe size
- Custom-designed to meet your specifications
- Special sizes, wattages, and materials are available upon request
- Units are available with larger vessels and heavier flanges
- Supplied with stainless steel parts and special design terminal boxes use in high temperature conditions
BENEFITS
- Easy to install
- Compact
- Clean
- Durable
- Highly energy efficient
- Provide fast response and even heat distribution
- Provide greater wattage in a smaller heater bundle
- Provide maximum dielectric strength
- Reduce heat loss from the vessel
- Protect and prevent thermal insulation
- Easy mounting support
- Suitable to general purpose terminal enclosures, weather or moisture resistant terminal enclosures, and unsafe or explosion proof locations
- Compatible with standard industry piping and safety standards
- Designed and built for safety
FACTORS
Please consider the following factors in order to select the proper circulation heater:
- Operating temperature
- Heating element watt density
- Sheath material (corrosive or non corrosive)
- Temperature of the corrodent
- Degree of aeration of exposed corrodent
- Velocity of the corrodent
REGISTRATION
Circulation heaters are sometimes considered as boilers or pressure vessels according to the:
- Heated fluid
- KW rating
- Size of vessel
- Operating pressure
- Outlet temperature
Where applicable, registration requirements are imposed by law and according to the installation location.
EXTRA FEATURES
- Available built-in high limit controls and thermostats
- Standard built-in thermostats: Single pole device limited to 240V up to 30 amps
- For heater voltage over 240V, or heater currents over 30 amps, or three-phase supply, the thermostat is used for pilot duty only and is not factory wired to the elements.
