Our Sample Cooling Coils

Designed for complex process needs.

This equipment is designed to cool hot water and condensate and to sub-cool steam samples, offering a range of materials and tubing options to suit complex process needs.


Nor’West Sample Cooling Coils

The culmination of 40 years of expert engineering.

Carefully designed by Nor’West Controls, and recently acquired into the TIW Western portfolio, our sample coolers are designed for use with the steam grab samples on our OTSG packages and are custom-engineered to integrate with any process system that requires a cooled sample stream.

About Sample Cooling Coils

designed to cool down process sample streams.

Our tube in tube sample cooling coils are designed to cool down process sample streams. And while critically important for safe handling, sample cooling coils also allow for industrial steam and liquid samples to be cooled to temperatures that facilitate accurate test results and prevent damage to your testing equipment.

Sample cooling coils are a counterflow tube-in-tube arrangement. As the hot fluid travels through the coil, it loses heat to the surrounding cooling fluid until it’s a safe temperature for testing or grab sampling.

Why Choose Our Sample Cooling Coils

engineered to ensure reliable temperature reduction.

Our analytical sample cooling coils are engineered to ensure reliable temperature reduction of process samples in demanding industrial environments.

Each cooler is constructed from standard tube fittings and tubing although we manufacture them in a wide array of materials and wall thicknesses, depending on your process conditions. They’re both versatile and easy to maintain with a modular design that allows for tube extensions at custom connection points to accommodate any sample connection type you prefer.

We’ve designed a counterflow configuration which maximizes heat transfer efficiency, and the absence of sharp bends significantly reduces the risk of fouling or plugging, which we’ve gone one step further to prevent with a fully drainable design for easy maintenance and process integrity.

Additionally, the high-pressure sample tube is built without any external connections, which is a much safer design.

Each unit is supplied with a Canadian Registration Number (CRN) and is suitable for installation in ASME B31.3 piping systems.

Do you need an upgrade?

It might be time For a Replacement

If you have a new high-temperature fluid system that requires frequent testing, your system’s pressure, temperature, or fluid type has changed, or if your current sample cooling coil displays signs of corrosion, cracking, or reduced efficiency, we can provide a replacement, custom-engineered for your system.
