Supported Applications
The Omega MTO2-LIGHT series consists of lightweight oil immersion heaters featuring a two-element design. These units are explicitly designed for use with lightweight oils. The product overview states that the immersion heater should be used with an approved temperature control device to assure safe operation.
Operating Conditions & Performance
The MTO2-LIGHT series operates on 1-phase power at voltages of 120, 208, 240, or 480V. Power ratings range from 1.5 to 6 kW, with watt densities specified between 23 and 26 W/in². The heater sheath has a diameter of 1.2 cm (0.475").
The series utilizes a rugged steel sheath construction. Electrical connections are made via a 2 NPT Steel Screw Plug, which also serves as the process connection.
Safety and Approvals
- UL Listed
- CSA Certified
- NRTL/C Certified
- Made in USA
A caution note indicates that fire and electrical shock may result if products are used improperly or installed by non-qualified personnel. Additionally, abnormal application or use of heaters at excessive temperatures can create hazardous conditions leading to fire.
Configuration Options
The series is configurable across power ratings, voltage inputs, and enclosure types. The model number guide follows the format MTO-<kW>_<E1/E2>/<Voltage>.
Enclosure Options
The series offers two distinct enclosure configurations:
- E1 General Purpose Enclosure: NEMA-1 rated. Heaters with this enclosure are UL recognized and CSA Certified.
- E2 Moisture Resistant/Explosion Resistant Enclosure: Provides explosion resisting containment of electrical wiring according to the National Electric Code. These units are CSA NRTL/C Certified.
Dimensions by Power Rating (E1 vs E2)
The overall dimension "B" varies based on power rating and enclosure type:
- E1 General Purpose Enclosure Dimensions (Dim. B):
- 1.5 kW: 30 cm (11¾")
- 2 kW: 45 cm (17¾")
- 2.5 kW: 9 cm (19⅝") — Note: Source text lists "9" for this row; verify against physical documentation if critical.
- 3 kW: 63 cm (24⅞")
- 4 kW: 83 cm (32¾")
- 5 kW: 102 cm (40¼")
- E2 Moisture Resistant/Explosion Resistant Enclosure Dimensions:
- The E2 enclosure includes a thermowell dimension of 8.6 cm (3-3/8"), whereas the E1 general purpose enclosure lists a thermowell dimension of 10.2 cm (4").
Key Product Differences
Variants within the MTO2-LIGHT series are distinguished by power output, voltage selection, and enclosure type.
- Power Ratings: Available in 1.5 kW, 2 kW, 2.5 kW, 3 kW, 4 kW, and 5 kW configurations (with a documented range up to 6 kW).
- Voltage Selections: Models are designated by inserting the voltage value into the model number (e.g., "120" for 120 Vac, "208" for 208 Vac, "240" for 240 Vac, or "480" for 480 Vac).
- Enclosure Designation: The model suffix indicates the enclosure type: A denotes the E1 General Purpose Enclosure (NEMA-1 rated), while E2 denotes the Moisture Resistant/Explosion Resistant Enclosure.
- Weight Differences: For a given power rating, the E2 enclosure units are heavier than their E1 counterparts. For example, at 1.5 kW, the E1 unit weighs 1 kg (3 lb), while the E2 unit weighs 3 kg (6 lb).
