Heavy Equipment Cold Protection

Turn-key cold weather equipment protection systems help maintain optimum performance and reduce breakdowns


Thermex Engineering Systems is a custom design-build supplier of Fluid and Fuel Warming Systems, Idle Reduction SystemsFreeze Protection Systems and Specialty Equipment for heavy industry fleets such as Oil and Gas.


Bitter cold and freezing temperatures can take quickly take their toll on heavy equipment. Hydraulic fluid, fuel lines and batteries can freeze up making it near impossible to keep your fleet running properly. Without using drastic measures such as overnight idling to maintain engine temperature, or running diesel heaters 24 hours a day to keep systems from locking up, there are few options available.


Thermex systems can help you to keep your fleet of heavy equipment in top condition, avoiding costly maintenance or potential system failure and lockup during cold weather. Saving you money on maintenance, fuel costs, and equipment replacement on the job site.
