Simplify Your Fall HVAC maintenance with a Winters TTD Tridicator

Cooler fall weather may seem far off, but right now is the perfect time to think about HVAC maintenance. Ensuring your heating system runs efficiently through the colder months is crucial, and one way to simplify maintenance is by upgrading to a tridicator.

Tridicators like Winters' TTD Series Tricator greatly simply maintenance and cost by combining highly-precise pressure and temperature measurement into a single, easy-to-use device. The TTD in particular is ideal for use in boiler assemblies with high volumes of hot water and steam.

Available with both 2.5" (63mm) and 3" (75mm) dial faces, the TTD offers dual scale temperature measurement (°F & °C) and options for 1" (25mm) , 2" (50mm) and 2.5" (63mm) stems. The TTD can be customized with multiple temperature and pressure ranges - all of which are compliant with ASME Boiler Code Section IV HG-612 industry standards.

We also offer the TST Tridicator Shut-Off Thermowell as an accessory, which features a spring-loaded design that allows it to stay open when the tridicator is installed and automatically closes upon removal. This design minimizes system downtime with quick instrument replacement, while preventing media from exiting the system. The thermowell is CRN registered, has a pressure rating of up to 250 psi (matching the TTD Tridicator), and comes with a 5-year warranty.
