Freeze Protection & Temperature Maintenance

Nothing freezes overnight and nothing falls out of spec

A frozen instrument line or a batch outside temperature spec costs a shift, not a component, and it always happens on the coldest night of the year. Electric heat trace, immersion heating and pre-traced tubing bundles hold pipes, vessels and instrument lines at temperature, including inside hazardous areas.

How Freeze Protection and Temperature Maintenance Works

Trace the line, heat the vessel, protect the instruments.

1

Trace the Line

Heat trace cable runs the length of the pipework and adds back exactly the heat the line loses, sized from pipe diameter, insulation and the coldest ambient you get.

2

Heat the Vessel or Medium

Immersion heating brings tanks, process fluids and storage vessels up to temperature and holds them there, sized to duty, not chosen off a shelf.

3

Protect Instrument and Impulse Lines

Pre-insulated, pre-traced tubing bundles keep analyser and impulse lines flowing and reading accurately in freezing conditions.

What Sites Get Out of It

The outcomes that matter on site.

Snowflake indicating frost protection

No Frozen Lines When Winter Hits

Frost protection engineered in, not discovered missing during the first cold snap.

Thermometer holding temperature

Process Temperature Held Within Spec

Product stays flowable and in-spec through pipework, vessels and transfer lines.

Compliance shield with tick

Hazardous-Area Certified Heating

Trace and heating systems for certified zones, one compliance conversation, not two.

Instrument gauge reading correctly

Instrument Readings You Can Trust in the Cold

Traced tubing bundles stop impulse-line freezing that corrupts pressure and flow measurement.

Reliable Gas Sampling at a NSW Gas Storage Facility

Sampling and carrier gas lines had to run 50 metres from the storage racks to the chromatograph analysers, hold sample temperature the whole way, and meet Zone 2 IIA T1 Gc. A Thermon BSX-8-2 analyser bundle carried the sampling line; an SP/MP stream-traced multi-tube bundle consolidated hydrogen, nitrogen and zero air into one run, cutting fittings and leak points.

Three Questions We Ask First
Q1

Where does it run?

Ambient minimum, pipe size and insulation, and whether the line is in a hazardous area.

Q2

What is it doing?

Preventing freeze-up, or holding product at a set temperature.

Q3

What if it is wrong?

A frozen line or product out of spec. So we check heat loss and certification before the order.

Send Us the Line, the Medium and the Minimum Temperature

Pipe size and length, insulation, ambient minimum and the temperature you need to hold. We will size the trace or heater, specify the controls, and confirm the hazardous area rating.
