Question about steam heat when hauling latex in a tanker

If your carrier try’s to talk you into putting in transit heat on your tractor I’d think hard about that. I’d rather sit at tank wash to get it steamed then risk anything with my engine. For the little bit of money the carrier charges the customer for using your engine heat…….

 

Used to figure in winter 5 degree drop per 24 hours on fully loaded insulated tank, Iso tank was near 10/24 hours.
The ones we had at least.

 

Personally I would steam it to 115-120. We have newer trailers and plan on losing 2-3 degrees a day in the winter and 1-2 summer. Older trailers plan on losing 5-7 a day in winter and 3-4 summer. I can't honestly remember the steam time on Latex, but I can tell you when I was a driver I would stop every week and have a load of Resin steamed and it was 4-5 hours to get it to 160. (Resin is thinner then Latex)

 

That's a new one on me. Intransit Heat is not going to heat the load up as a rule. It's meant to slow down the heat loss. Any modern truck has a water pump strong enough to run intransit heat. It just circulates the coolant through the trailer as well as the trailer. I have heard of trucks running either hot or cold depending on the temp of the product, but even that is suspicious.

 

When I was at circle C they had a guy cook a load with in transit heat …. They ended up buying the load from Dow of course…… We heard about that screw up for years from management

 

Do not use transit heat on latex. The reason they want you to steam it is so you can monitor the temperature. Latex will change color if overheated Thus it will be a rejected load.
Heat it to the temperature they tell you too and run with it. You will not lose that much heat in 3-4 hours.
