SCENARIO

Typical duty
Read the process, then the equipment

Plating pre-treatment, machine washing, food processing and chemical storage all need the liquid in a tank or vessel heated and held. Water-based liquids scale, oils and chemicals attack materials, and falling level brings dry-fire risk — together these decide element construction and material.

Scaling and deposits

Hard water and process residue scale onto the element, cutting heat transfer and causing local overheating, so surface load must be limited and cleaning left accessible.

Level and dry fire

When draining or evaporation drops the level, uncovered elements overheat and fail, so level protection is mandatory.

Media corrosion

Acids, alkalis, salts and chlorides attack stainless steel; sheath material — 316L, titanium, PTFE — is chosen against the medium.

Temperature uniformity

A single point in a large tank stratifies; elements must be distributed or combined with circulation and agitation.

SOLUTION PATH

From duty to equipment,
four steps

  1. 01

    Confirm medium and volume

    Establish liquid type, volume, target temperature and heat-up time, then calculate heat-up power and holding power.

  2. 02

    Choose the element form

    Select flanged, threaded or external circulation heating according to tank structure, and fix element position and spacing.

  3. 03

    Set material and load

    Pick the sheath material from corrosivity and scaling tendency, limit surface watt density, and leave clearance for cleaning and replacement in scaling duty.

  4. 04

    Add protection

    Low-level cut-out, over-temperature protection and a temperature controller, with a circulation pump where uniformity needs help.

FAQ

Common questions

01The tank scales heavily — what helps?+

Limiting surface load is the root fix: choose low watt-density elements in scaling duty and descale on a schedule. Where water quality is very poor, external circulation heating keeps the elements out of the bath.

02Can it run in acidic liquid?+

Sheath material follows concentration and temperature — commonly 316L, titanium or PTFE covering. For strongly corrosive media, send the full medium analysis before confirmation.

03Does it cut out when the level drops?+

It can. A level switch or electrode level gauge interlocks into the control cabinet, cutting heating and alarming below the set level to prevent dry firing.
