Supported Applications
The Omega ARMTI Series consists of immersion heaters featuring an Incoloy sheath and a 2 NPT stainless steel fitting. These units are designed for severe, hard water applications with a pH range of 5 to 9. Each heater incorporates two heating elements and includes an integral thermostat configured as a temperature control device.
Operating Conditions & Performance
The series operates on 240 or 480V, 1 phase power with wattage ratings ranging from 2 to 15 kW. The process operating temperature is specified at 60 to 250°F; a T-1 Temp Range option provides control for 0 to 100°F. Watt density across the series spans 46 to 51 W/in², depending on the specific model configuration.
Important safety notes state that the integral thermostat functions as a temperature control only and is not a fail-safe device. An approved pressure or temperature control should be used with these heaters to assure safe operation.
Configuration Options
The ARMTI Series offers configurable dimensions, power ratings, and enclosure types to meet specific installation requirements.
- Power & Phase: 240 or 480V, 1 phase; wattage from 2 kW to 15 kW.
- Sheath Material: Incoloy with a diameter of 1.2 cm (0.475").
- Process Connection: 2 NPT stainless steel screw plug fitting containing two heating elements.
- Enclosure Options: Available in General Purpose, NEMA-1 rated enclosures or Type E2 moisture resistant/explosion resistant enclosures.
- Electrical Connections: Features 2 NPT conduit hubs (one side plugged) or a hole for 3/4" conduit.
The series supports various insertion lengths and overall dimensions based on the selected wattage. For example, models range from an overall length of 16.72 cm (6 9/16 inches) (for E1 enclosures at lower wattages) to significantly longer configurations for higher power ratings.
Approvals & Certifications
- NEMA-1 Enclosures: UL Listed and CSA Certified, except models exceeding 48 amps (marked with †).
- Type E2 Enclosures: CSA NRTL/C certified. These are not intended for use in hazardous areas.
Ordering Configuration
The model number structure follows the format: ARMTI-<kW>-<Phase>-<W/in²>-<Dim. B (in)>-<Model No.>-<Enclosure Type>. Voltage is specified by inserting "240" for 240 Vac or "480" for 480 Vac into the part number.
Key Product Differences
Variants within the ARMTI Series are distinguished primarily by power rating, enclosure type, and temperature range settings. The General Purpose (E1) models feature a NEMA-1 rated enclosure, while Type E2 variants provide moisture resistant/explosion resistant housing.
Temperature control ranges vary between standard operation at 60 to 250°F and the T-1 option for 0 to 100°F. Physical dimensions differ by wattage; higher kW models require longer overall lengths (Dim B) ranging from approximately 8 inches up to 54 inches depending on the specific power output.
