Fuel dispensing system with heating system

摘要

Embodiments of a heating system maintains the temperature of a fuel additive (e.g., AUS32) at and/or above freezing temperature to avoid crystallization. The heating system can form a fluid circuit with one or more coaxially arranged sleeves disposed about hoses that transport the additives. The fluid circuit can also include a central compartment that encloses a flow meter. A fluid heater couples with the fluid circuit to provide heating fluid, e.g., to the central compartment. The heating fluid disperses throughout the heating compartment and into the sleeves, thereby direction heating fluid in thermal proximity to the hoses and other components that handle the fuel additive.

主权项

1. A heating system for a fuel dispenser, said heating system comprising:
a central compartment having an inlet configured to receive a fuel additive from a storage tank storing the fuel additive, and the central compartment having an outlet configured to allow the fuel additive to exit the central compartment; and an elongated sleeve coupled with the central compartment, the elongated sleeve being configured to circulate heated fluid therein and circumscribing a hose that is configured to carry the fuel additive in the fuel dispenser such that the circulating heating fluid heats the fuel additive carried by the hose.
