Application intelligence / Collection 1.0
HVAC & geothermal
Turn operating temperatures, formulation data, and service history into a more useful heat-transfer-fluid specification.
From application to a better specification
Freeze protection is not the whole operating envelope
Separate the protection objective from the evidence needed to operate and pump the selected fluid.

Make unknown fill chemistry and missing acceptance evidence visible before ordering replacement fluid.
Read the guide →03 / Research briefRead geothermal case studies at the right scale

Read the guide →04 / Application guideInhibited and uninhibited glycol are different purchases
What an inhibitor package is, what it is not, and the four things to write down so a quote answers the right question.
Read the guide →05 / Purchasing guideA corrosion-inhibitor claim is a claim about evidence
Which parts of an inhibitor claim you can actually read, which sit behind a paywall, and how to record the difference.
Read the guide →06 / Application guideColour tells you who dyed it, and nothing else
What a glycol’s colour does and does not mean, and what actually governs how the drum is stored.

Build a requirements brief
Keep requirements, evidence and open questions together. Entries stay in this page’s memory until you leave or reload; this worksheet does not submit them. Download a text copy for your own review. Do not enter confidential or controlled technical information.
Connect the requirement to the material
Once your team has defined the application requirements, review the exact product’s available documents. Ask about packaging, lot evidence and unresolved sourcing questions; an industry listing is not an application approval.
