Supported Applications
The Omega HTWAT Series consists of silicone rubber heating tapes with built-in adjustable thermostat control. These flexible heaters are designed for process temperature control, freeze protection, and supplemental heat applications.
Documented use cases include wrapping around valves, pipe lines, bearings, filter housings, actuators, and similar objects to maintain a set temperature via the integral controller.
Operating Conditions & Performance
The HTWAT series features an adjustable thermostat range of 10 to 218°C (50 to 425°F). The maximum exposure temperature for the heater is rated at 232°C (450°F).
- Power Density: Nominal watt density is specified as 6.0 Watts/in² (0.009 Watts/mm²).
- Bend Radius: The minimum bend radius is 12.7 mm (0.5").
- Suitability: Suitable for use on electrically conductive surfaces.
- Resistance Properties: Models are described as moisture and chemical resistant.
Voltage & Power Supply
The series operates on 120 or 240 Vac. Electrical connections differ by voltage model: 120V models include a power cord with plug, while 240V models are supplied without plugs and feature stripped lead ends requiring termination.
Configuration Options
The HTWAT series is configurable across multiple dimensions including width, length, voltage, and total wattage. The flexible tape construction utilizes an extruded silicone rubber outer sheath with fiberglass knitted and braided internal components.
Sizing Options (Width x Length)
- 0.5" Width: Available in lengths from 2' to 10'. Power ranges from 72 W to 360 W for 120V models.
- 1.0" Width: Available in lengths from 2' to 10'. Power ranges from 144 W to 720 W for 120V models.
- 2.0" Width: Available in lengths from 2' to 10'. Power ranges from 288 W to 1,440 W for 120V models.
- 3.0" Width: Available in lengths from 2' to 10'. Power ranges from 432 W to 1,440 W (or up to 1,800 W on specific 240V configurations) for 120V models.
Model Numbering Structure
The series follows a model number guide format of HTWAT-, where the segments denote width, voltage type (1 for 120VAC, 2 for 240VAC), and length. For example, HTWAT051-002 represents a heating tape with specific dimensional and electrical parameters.
Key Product Differences
Variants within the HTWAT series are distinguished primarily by physical dimensions (width in inches/mm) and total length, which directly determine the wattage output. The primary functional variation is between 120VAC models equipped with a NEMA plug on a 1.8 m (6') cord and 240VAC models supplied without plugs.
Specific power outputs vary by size; for instance, the largest available configuration in the series reaches up to 1,440 W or 1,800 W depending on voltage selection. The integral thermostat is standard across all variants, providing temperature maintenance within the specified range of 50-425°F (10-218°C).
