Supported Applications
The Omega NWHMTOR Series is a circulation heater designed for medium and heavy weight oil applications. The series features a 2½" carbon steel pipe body with a 150 lb construction rating, utilizing three low watt density elements (15 W/in²) to provide heating within the fluid loop.
Operating Conditions & Performance
The NWHMTOR Series operates across power ratings from 1 kW to 9 kW. Electrical supply options include 120, 240, and 480V in both single-phase (1-1) and three-phase (1-3) configurations. The unit incorporates an integral thermostat with a control range of 60 to 250°F.
Physical dimensions vary by model power rating: overall length dimension A ranges from 21¾" to 79¼", width B from 9" to 67", and height C up to 61". Unit weight spans from 10 lb for the 1 kW models to 54 lb for the 9 kW configurations.
Key Specifications
- Power Range: 1, 3, 5, 7.5, and 9 kW
- Voltage/Phase: 120V (1-Ph), 240V (1 & 3 Ph), 480V (1 & 3 Ph)
- Process Connection: 2½" NPT Steel Screw Plug Design
- Element Configuration: Three 0.475" diameter steel sheath elements at 15 W/in²
- Thermostat Range: 60 to 250°F (integral)
- Housing Material: Carbon Steel Pipe Body; Wetted materials include ASTM A53B carbon steel pipe and ASTM A516 Grade 70 carbon steel plate
Configuration Options
The series offers configurable terminal enclosures to suit different environmental requirements. Models are available with E1 General Purpose, E2 Moisture Resistant/Explosion Resistant, or E4 Moisture Resistant enclosures.
- Terminal Enclosure Options:
- E1: General Purpose
- E2: Moisture Resistant/Explosion Resistant (Note — Add 2" to A dimension for E2 Enclosure)
- E4: Moisture Resistant
- Electrical Connection: Convenient field wiring terminals provided for easy installation via a 3/8" NPT Pipe Plug.
- Certifications: UL and CSA approved; other third-party approval, listing, or certification available.
Key Product Differences
The model number structure defines the specific configuration: NWHMTOR-<Number of Elements>-<kW Code>-<Terminal Enclosure Code>-<Voltage/Phase Code>. For example, NWHMTOR-03-005P-E1/240 denotes a unit with three elements (code 03), 5 kW power (code 005P), E1 General Purpose enclosure, and 240V single-phase supply.
Power codes correspond to specific wattage outputs: 003P for 3 kW, 04P5 for 4.5 kW, 006P for 6 kW, 07P5 for 7.5 kW, and 009P for 9 kW. The number of elements is fixed at three (code 03) across the series.
