>> Over the Side
TruHeat has considerable experience in aqueous immersion heating elements. The first heating assembly offered by TruHeat was an immersion screw plug unit in 1959. Flanged and pipe plug units are very popular in the OEM immersion market, and TruHeat offers a broad range of options in both applications.
Over the side immersion units provide benefits such as retrofit ability, ease of use, and the ability to remove the heating assembly without draining the tank, thus offering practical replacement.
There are two critical points to consider when designing immersion elements, Watt Density, and Sheath Material.
Watt Density needs to be low enough to hold the solution under the recommended operating temperature and Sheath Material must be considered when dealing with corrosive solutions (See Table TH1).
TruHeat offers eleven standard sheath materials:
- Cold Rolled Steel (CRS)
- Copper Coated Steel (CCS)
- Aluminum (ALUM)
- Copper
- 304 Stainless Steel (SS304)
- 321 Stainless Steel (SS321)
- 316 Stainless Steel (SS316)
- Incoloy 840 (I840)
- Incoloy 800 (I800)
- Incoloy 825 (I825)
- Titanium (TITAN)
- Monel is available upon special request.
TruHeat offers three standard enclosures:
- NEMA 1 – General Purpose
- NEMA 4 – Weather Resistant
- NEMA 7 – Explosion Proof
* For immersion wattage estimation tables see Table TH2 for water based solutions and Table TH4 for oil based solutions. See Table TH5 for Amperage conversion tables for single and three-phase units. See Graph TH3 for Heat Losses from Water & Oil Surfaces.
