Sanitary Screw-Plug Immersion Heaters for Water



Heat water through direct contact in sanitary areas such as food, cosmetic, and pharmaceutical plants. Made of 316 stainless steel, these immersion heaters won’t corrode from harsh cleaners and sanitizers. To minimize bacteria growth and make them easier to clean, the heating element has an electropolished finish that’s free of crevices. Rated NEMA 4, their housing is protected against dirt and washdowns.
These heaters have screw plugs for mounting to threaded container openings or pipe couplings.
Heaters with an adjustable thermostat automatically turn on when the water drops below a set temperature and turn off once it reaches that temperature. Heaters without an adjustable thermostat require a temperature switch or controller (not included) to control heat output.
Note: Fully immerse the heating element in liquid to prevent heater failure.

Sanitary Thermocouple Probes for Liquids and Gases

Designed to measure temperature in dairy and food-processing applications, these probes are built to maintain sanitary standards. They have a sanitary quick-clamp connection that’s easy to disconnect for cleaning. IP65 and NEMA 4 rated, they seal out water from washdowns from top to bottom. The probes are polished stainless steel, so they're easy to clean and won't corrode from harsh cleaning chemicals or immersion in liquids or gases. The stainless steel also shields the sensor inside from impact, while magnesium oxide protects the wiring. Remove the cap on the head to wire the thermocouple to your application. The fitting is welded on, so you can’t adjust the probe’s length.
Pick the thermocouple type that best covers the temperature range you expect your liquid or gas to be. You should also make sure the thermocouple type you choose is compatible with the device you plan to connect it to. They’re often used with temperature controllers, thermometers, and other temperature-reading devices.
These thermocouples are manufactured to conform to ASTM E230 for accuracy. Accuracy is how far off the reported value is from the actual temperature.

Heated High-Pressure Wet-Food and Beverage Hose with Sanitary Fittings

- Temperature Range: 72° to 450° F
- Maximum Vacuum: 28" of Hg @ 70° F
- Material: PTFE with Vinyl Plastic Cover and 304 Stainless Steel Braid
- Color: Blue
- Environmental Rating: IP65
- Specifications Met: FDA Compliant 21 CFR 177.2600
Warm viscous food and beverages, such as syrup and honey, to keep it flowing even when the temperature drops. This hose is lined with heating wire. To regulate heat output, a built-in thermocouple measures the hose’s temperature and sends it to your temperature switch or controller (required but not included).
This hose is FDA compliant, so it’s safe to use with food. A stainless steel braid strengthens the hose and resists chemicals commonly found in cleaning processes for food plants. To prevent damage to the braid, a vinyl cover surrounds it. Rated IP65, this hose also seals out spraying water.
The fittings on this hose are also called tri-clamp fittings. They attach to other quick-clamp fittings with a gasket and a clamp.
