Instant Process Heating. Maximum Efficiency.
Precision Process Heating from Hydro-Thermal
When product quality depends on precise temperature control, Direct Steam Injection (DSI) delivers. Hydro-Thermal systems inject steam directly into the process fluid to provide near-instant heating with temperature accuracy within +/- 1°F, reducing process variability while eliminating many of the fouling and maintenance challenges associated with traditional heat exchangers.
As your Hydro-Thermal partner, Crane Engineering helps you select the right solution to improve process performance, product quality, and operating efficiency.
From the HYDRON™ Sanitary Hydroheater designed for hygienic food and beverage applications, to the flagship Hydroheater® for industrial process heating, every product is engineered for performance, reliability, and total cost of ownership.

What Is Direct Steam Injection?
Direct Steam Injection (DSI) is a process heating method that injects steam directly into a flowing liquid stream, transferring heat instantly without the need for a traditional heat exchanger.
Unlike shell-and-tube or plate heat exchangers that rely on indirect heat transfer, DSI heats process fluids immediately and uniformly. The result is rapid temperature control, improved energy efficiency, and reduced maintenance by eliminating fouling surfaces that require frequent cleaning.
Whether you're heating water, slurries, chemicals, food products, or process liquids, Direct Steam Injection delivers fast, consistent performance while helping protect product quality.
